Description

Docket No.57TIA12652WO / 209565-89 ACTIVE COLD-WEATHER PROTECTION GARMENT CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application depends from and claims priority to U.S. Provisional Application No.63 / 542,911 filed October 06, 2023, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure is generally directed to heated garments, and more specifically, garments having a low-profile heating capability and robust power source technology. BACKGROUND

[0003] Currently, most available heated clothing uses wires mounted onto separate panels whereby these panels are then stitched or bonded to synthetic fill or other textile substrates. The heating elements are formed from a combination of thick and thin wires. The power source is typically a large battery or power bank that is stored in a pocket. Other types of heated clothing include single-use packs containing heating chemicals that become hot when exposed to air. Other single-use packs contain a gel and are microwaved before use. These single use packs stay warm for a limited but uncontrolled time and since they have no temperature control, they can become too hot.

[0004] Current technologies have limitations in usability, temperature range, and power constraints, among others. Current cold weather protection is provided by multi-layer systems that are typically bulky and impede range of motion making activities difficult to perform. Furthermore, these systems can cause thermal burden if a person is physically active while wearing them. Multi-layer systems, while tailorable and scalable, are difficult to adjust (removing layers) while being worn.Docket No.57TIA12652WO / 209565-89

[0005] Additionally, currently available heated clothing is not capable of being effectively washed without removal of the power source due to the risk of damaging the electrical components, shorting the battery, and in some instances damaging the insulation.

[0006] Accordingly, a need exists to develop heated clothing that operates in extreme temperatures, is capable of being washed, and optionally reduces the bulk of currently available options. SUMMARY

In some embodiments, the heated textile architecture includes a management circuit communicatively coupled to the power source, optionally configured to discharge the power source to a voltage of less than 0.1 Volts, optionally about zero Volts. In some embodiments, the heated textile architecture includes a temperature sensor, optionally communicatively coupled to the management circuit. In someDocket No.57TIA12652WO / 209565-89 embodiments, the heated textile architecture includes a user input, optionally communicatively coupled to the management circuit, such that the user input device can modulate the current generated by the power source.

[0009] In another embodiment, the present disclosure provides a heated garment comprising a fabric base layer and a heated textile architecture. Optionally, the fabric base layer includes a 4-way stretch material. In some embodiments, the fabric base layer and the heated textile architecture are intrinsic to the design of the heated garment.

[0018] This disclosure provides heated textile architectures and heated garments, along with methods of producing and using such garments. The garments generally include a fabric base layer, fashioned into an article of clothing, and one or more integrated heating elements, such as the heated textile architectures of the present disclosure. Aspects of the present disclosure address a need for energy storage capabilities and operation in extremely cold environments; provide adaptability of the heated garment during various activities, preventing the need to shed or adjust layers; and provide an active heating solution that can extend the length of time a wearer can spend in the extreme cold. These and other advantages of the heated textile architecture and garments of the present disclosure will become clearer from the following description.

[0019] Heated garments as provided herein generally include integrated heating elements referred to herein as a “heated textile architecture.” Referring now to the drawings, FIG. 1 schematically depicts an exemplary embodiment of a heated textile architecture 100 in accordance with the present disclosure. In some embodiments, the heated textile architecture 100 provides warmth to the heated garment by converting electrical energy into heat through conductive materials, described in greater detail herein.Docket No.57TIA12652WO / 209565-89

[0020] The heated textile architecture 100 may provide tailorable, active warmth, optionally in extreme cold weather environments. Tailorable, active warmth in a heated garment refers to the ability to provide adjustable and customizable thermal comfort to the wearer, allowing for control over the level of warmth based on individual preferences of the wearer and / or environmental conditions, described in greater detail herein. In some embodiments, the heated textile architecture 100 is configurable and adjustable for the preference and / or needs of the wearer, described in greater detail herein. For example, and without being bound by theory, the heated textile architecture 100 may be integrated into a management circuitry, depicted FIG.3 and described in greater detail herein, to allow the wearer to adjust the temperature settings of the heated textile architecture 100 within the garment. In some embodiments, the management circuitry responds to changes in the surrounding environment or the wearer's activity level, providing warmth when needed and conserving energy when conditions are comfortable.

[0021] The heated textile architecture 100 may be constructed such that all or part(s) of the architecture may be a stand-alone component that can be integrated into a garment at any desired location. For example, the heated textile architecture 100 may be designed to allow for integration within a garment, meaning that all or specific components of the heating architecture can function as stand-alone modules. It will be appreciated that a modular design enables strategic placement of the heated textile architecture 100 in specific locations within a garment. For example, a modular design may allow for placement of the heated textile architecture 100 in areas where heat retention is more desired (e.g., near internal organs), while omitting the heated textile architecture 100 in other areas.

[0022] In some embodiments, the heated textile architecture 100 may include zoned heating elements. As used herein, zoned heating elements refers to a design approach where heating components are strategically placed to provide targeted warmth. Zoned heating may be achieved by alternating between conductive thread 104 and conductive strips 102, such as shown in FIG. 1. Alternatively, zoned heating may occur by the strategic placement of a plurality of heated textile architectures 100 within desired region(s) of a garment. The zoned heating elements may be configured to be independently controlled, optionally by the management circuitry, described in greater detail herein.Docket No.57TIA12652WO / 209565-89

[0023] Optionally, the heated textile architecture 100 may be constructed such that it intrinsic to the design of the heated garment. As used here in, “intrinsic” refers to a feature that is built into the core concept, structure, or function of a garment, such as fabric, cut, construction technique, or functional details that are integral to how the garment is made and worn. Intrinsic features cannot be added or removed without fundamentally altering the heated garment.

[0024] The heated textile architecture 100 may be sized and shaped such that the heated textile architecture 100 may be incorporated into a variety of sizes and / or garment types with little adjustment. For example, and without being bound by theory, the heated textile architecture 100 may be sized and / or shaped for a specific garment type or specific region of a garment. Although the heated textile architecture 100 is depicted as having a rectangular geometry in FIG. 1, the design of the heated textile architecture 100 is not limited to such geometric footprints and instead may be any suitable shape or size and containing any number of conductive strips 102 and / or conductive threads 104, described in greater detail herein. Other suitable geometries include, but are not limited to, circular geometries, elliptical geometries, triangular geometries, hexagonal geometries, radial geometries, spiral geometries, irregular shapes, linear shapes, grids, tessellated patterns, combinations thereof, and the like, though any suitable size or shape is contemplated and possible.

[0025] In some embodiments, such as shown in FIG. 1, the heated textile architecture 100 may be coupled to (e.g., stitched to) or directly integrated into a fabric base layer 10. Optionally, the heated textile architecture 100 is a low-profile, low-bulk heating system. The terms “low-profile” or “low-bulk” as used herein refer to a heated textile architecture 100 with minimal protrusion from the fabric base layer 10 to which it is attached. “Minimal protrusion” refers to a slight or negligible extension of the heated textile architecture 100 beyond the surface of the fabric base layer 10. It will be appreciated that, in some embodiments, the heated textile architecture 100 does not create a significant raised or bulky area on the fabric base layer 10, optionally avoiding noticeable elevation or irregularity in the garment’s profile, preserving the appearance and feel of the fabric base layer 10.Docket No.57TIA12652WO / 209565-89

[0026] The integration of the heated textile architecture 100 within garments may be achieved through various design and construction methods. In some embodiments, described in greater detail herein, the heated textile architecture 100 may be directly integrated into the fabric base layer 10, optionally incorporated into a garment during final assembly. In some embodiments, the heated textile architecture 100 may be overlayered with a fabric base layer 10. For example, the heated textile architecture 100 may be directly constructed onto or embedded into the garment during the manufacturing process. It will be appreciated that the integration method depends on factors such as the garment's design, intended use, structural and / or aesthetic characteristics, and the desired performance of the heated textile architecture 100.

[0027] The heated textile architecture 100 generally includes one or more conductive strips 102, 102’, conductive thread 104, and a power source 106. In some embodiments, the conductive thread 104, the conductive strips 102, 102’ and / or the power source 106 are electrically coupled to one another. As used herein, “electrically coupled” refers to two or more components being connected in such a way that they can transmit electrical signals and / or power between them. It will be appreciated that electrically coupled refers to both direct and / or indirect connections. As used herein, a direct connection refers to a physical link between two or more components where electrical current flows without the need for intermediate devices. Exemplary direct connections include wiring between components, soldering joints, traces, and / or terminals. Contrastingly, an indirect electrical connection refers to a connection between two or more components that is mediated by intermediate elements, such as resistors, capacitors, inductors, transformers, or electronic circuits, rather than a simple wire or conductive path. These intermediaries may modify or regulate the flow of electrical current or signal between the components. Exemplary indirect connections include transformer-based connections, capacitive coupling, optocoupling, relay switches, and the like.

[0028] In some embodiments, the heated textile architecture 100 includes one or more conductive strips 102, 102’ electrically coupled to the power source 106. It will be appreciated that, in some embodiments, the conductive strips 102, 102’ distribute current throughout all or targeted portions of the garment, optionally serving as both electrical conduits and heatingDocket No.57TIA12652WO / 209565-89 elements. In some embodiments, an electrical conduit does not have sufficient resistance to allow functional heating, whereas a heating element does.

[0029] The conductive strips 102 may be conductive textile strips, textile strips that incorporate one or more conductive elements, such as metal fibers, conductive threads, and / or conductive coatings, and / or other configurations referred to herein collectively but without limitation as strips. Conductive strips 102 may be woven, embroidered, printed, and / or coated with conductive materials. In some embodiments, the conductive strips 102, 102’ distribute current from the power source 106. Optionally, the conductive strips 102, 102’ may be arranged over and / or through the fabric base layer 10.

[0030] The conductive strips 102, 102’ may be formed from any suitable conductive material, such as textiles that are woven or coated with conductive materials (e.g., silver or carbon) to make them conductive, textiles that incorporate conductive elements (e.g., wires or conductive threads) into the textile structure, or textiles that have a metallic coating, (e.g., aluminum or copper) to make them conductive. Optionally, the conductive strip(s) 102 may be formed from a low-resistance material. As used herein, a low-resistance material refers to a material that offer minimal opposition to the flow of electric current, allowing energy to pass through. It will be appreciated that low-resistance materials may enable even distribution of current across a garment’s surface, thereby reducing localized overheating or loss of efficiency.

[0031] The material of the conductive strips 102, 102’ may be selected to withstand the mechanical stresses of wearing and removing the garment while maintaining electrical communication with the power source 106 and the conductive thread(s) 104. Optionally, the material of the conductive strips 102, 102’ may be selected to withstand the mechanical stresses of laundering or submerging the garment while maintaining electrical communication with the power source 106 and the conductive thread 104.

[0032] The material used to form the conductive strips 102, 102’ may be dependent on its placement in a garment or the type of garment. For example and without being bound by theory, the conductive strips 102, 102’ may be made of a light-weight and / or flexible material (e.g., silver or carbon-coated fabric) to maintain conductivity while reducing bulk. As used herein, a light-weight material refers to any fabric or material engineered to have a reduced mass-to-Docket No.57TIA12652WO / 209565-89 volume ratio, providing ease of wear and movement, while still delivering mechanical strength, flexibility, and conductivity. Flexible material refers to a fabric or material designed to stretch, bend, or compress without permanent deformation or damage, while maintaining the structural integrity and conductivity. Exemplary light-weight and / or flexible materials include nylon, microfiber, rip stop fabrics, spandex, TENCEL®, polyester blends, smart textiles with shape- memory alloys, GORE-TEX®, combinations thereof, and the like.

[0033] In other embodiments, the conductive strips 102, 102’ may be made of stiffer materials for regions and seams where flexibility is less critical, or where excess movement may degrade conductivity. Conductive strips 102 may be constructed using woven, knitted, or nonwoven conductive textiles depending on the electrical performance needed to transmit the electrical current. It will be appreciated that these textile structures may have differing stiffness properties. Stiffer materials may provide a balance between electrical performance and mechanical stiffness, optionally making them suitable for seams that maintain shape and resist wear while transmitting electrical current efficiently. The stiffer materials may be used to prevent wear or breakage in the heated garments, optionally at seams or other locations where movement and bending may otherwise degrade conductivity over time.

[0034] Optionally, conductive strips 102, 102’ within the same heated textile architecture 100 may be made from different materials.

[0035] The conductive strips 102, 102’ may be layered and / or stitched together. In some embodiments, the conductive material may be folded into the conductive strip 102, such as shown in FIG. 2. Any suitable folding or layering method is contemplated and possible to achieve the conductive strips 102. Exemplary folds include trifolds, bifolds, Z-folds, combinations thereof, and the like.

[0036] The conductive strips 102, 102’ may be arranged such that they do not impede the garment’s ability to conform to the wearer’s body. In some embodiments, the conductive strips 102, 102’ are disposed in selective areas such as seams or low-wear areas, to distribute current, and optionally serving as an electrical bus for the heated textile architecture 100, described in greater detail herein. It will be appreciated that, in some embodiments, the conductive strips 102, 102’ may serve as both electrical conduits, delivering current to the conductive threadDocket No.57TIA12652WO / 209565-89 104, and a secondary heating mechanism in the heated textile architecture 100. A low-wear area, as used herein, refers to a region of a garment that experiences minimal friction, stress, or stretching during regular use. Low-wear areas may be less exposed to the wear and tear caused by movement, body contact, or abrasion with external surfaces.

[0037] Referring again to FIG. 1, the heated textile architecture 100 generally includes a plurality of conductive threads 104 coupled to and / or integral with the conductive strips 102. In some embodiments, the conductive strips 102, 102’ and the conductive thread 104 may be coupled to one another, optionally by stitching conductive thread 104 through the conductive strips 102, 102’. This stitched connection mechanically and electrically couples the conductive strips 102, 102’ and the conductive thread 104, enabling the transmission of current from the power source 106 across the heated textile architecture.

[0038] The conductive threads 104 may be formed of thin, smooth, and / or flexible materials. It will be appreciated that the material forming the conductive threads may be selected based on a variety of desired properties, including, but not limited to, conductivity, durability, corrosion resistance, flexibility, weight, and / or efficiency. Suitable materials for forming the conductive threads 104 include stainless steel, stainless-steel hybrids, metal-coated textile threads, conductive polymers, carbon nanotube composite yarns, combinations thereof, and the like.

[0039] Optionally, the conductive threads 104 are arranged to maximize heating efficiency, distribute heat evenly, and prevent shorting or overheating. The length, quantity, and / or stitch pattern of the conductive threads 104 may optionally be tailored to maximize heating while retaining stretch and comfort in the fabric base layer 10. For example, and without being bound by theory, in high-flex areas of a garment, such as elbows or knees, the conductive thread 104 may be arranged using a looser stitch pattern to allow for movement, while in areas where maximum heat is desired, such as the chest or back, the conductive thread 104 may be arranged in a dense stitch pattern to enhance electrical and functional properties of the heated textile architecture 100. It will be appreciated that a dense stitch pattern increases the amount of conductive material in a given area, thereby improving the overall conductivity and allowing for higher current capacity without overheating the fabric base layer 10.Docket No.57TIA12652WO / 209565-89

[0040] Optionally, the conductive thread 104 is arranged to allow current to pass from the power source 106 through the conductive thread 104 to generate heat via the resistive heating principle, to maintain controlled warmth in the heated textile architecture 100. The resistive properties of the conductive thread 104 enable the generation of heat as the electrical current passes through it. This conversion of electrical energy to thermal energy is used to provide controlled warmth throughout the heated textile architecture 100, ensuring that the wearer experiences consistent and comfortable heat without excessive power consumption. Optionally, the design of the conductive thread 104 arrangement and / or stitch pattern may be tailored to meet the specific heating requirements of the garment, such as maintaining a set temperature range or providing localized heating to specific areas, all while ensuring that the overall fabric remains comfortable and functional for the wearer, described in greater detail herein.

[0041] The heated textile architecture 100 also generally includes a power source 106. Optionally, the power source 106 is electrically coupled to the conductive strips 102, 102’ and / or the conductive thread 104. In some embodiments, the power source 106 is communicatively coupled to a management circuit, illustrated in FIG. 3 and described in greater detail herein. In some embodiments, the power source 106 is a battery. In some embodiments, the power source 106 includes a plurality of batteries, optionally distributed throughout the garment, described in greater detail herein.

[0042] Optionally, the battery includes one or more cells, described in greater detail herein. A cell within the power source 106 may be a button cell, optionally of varying sizes. In some embodiments, the power source 106 includes multi-layer, stacked pouch cells, optionally of different sizes and / or footprints. In some embodiments, the power source 106 includes wound prismatic and / or cylindrical cells. It will be appreciated that the cell size and voltage of the power source 106 may be selected to meet the power and energy demands for the heated textile architecture and / or the heated garment, described in greater detail herein.

[0043] Optionally, the power source 106 can be a single cell operating at about 1.0 Volt (V) to about 4.5 V, optionally about 2.5 V to about 3.3 V. In some embodiments, the power source 106 has a discharge voltage of about 1.0 volts. The power source 106 may have a max voltageDocket No.57TIA12652WO / 209565-89 of about 2.75 V and a discharged voltage of about 1.6 V. In some embodiments, the power source 106 has a plurality of cells, optionally combined in series or in parallel to generate the required operating voltage range.

[0044] The power source 106 may be configured to be distributed throughout a portion of the fabric base layer 10, such as by being sewn into or incorporated in the fabric base layer 10. Optionally, the power source 106 may act as an additional heating element, providing warmth to the wearer. For example, and without being bound by theory, in some embodiments, the power source 106 may be a battery that is designed such that it is incorporated into thread or a strip. In some embodiments, the power source 106, optionally a battery, may be incorporated anywhere in the garment. In some embodiments, the power source 106, optionally a battery, may be incorporated into the seams of the garment, described in greater detail herein.

As a non-limiting example, the power source 106 may be integrated into the heated textile architecture 100 and / or the heated garment, but remains removable by the wearer. In some embodiments, the power source 106 is selectively positioned within the garment at specific region(s), such as a side, forearm or other reachable area. In some embodiments, the power source 106 may be integrated into the heated textile architecture 100 and / or the heated garment and is not removable. In some embodiments, the power source 106 is robust and physically flexible. As used herein, “physically flexible” refers to a power source 106 that is capable of conforming to a three-dimensional surface. In some embodiments, a physically flexible power source 106 is one with similar flexibility to a webbing. Optionally, a physically flexible power source 106 is capable of forming other shapes by no more effort that imparted by a wearer of a garment.

[0049] The power source 106 may be configured to be repeatedly discharged. Optionally, the power source 106 is configured to be discharged to 0 volts without loss of performance of the battery.

[0050] Optionally, the power source 106 is capable of withstanding the zero-volt state for a long period of timesuch as but not limited to days, including 1 day, 2 days, 3, days, 4 days, 5 days, or 6 days, including any subrange having endpoints defined by any two of the aforementioned values.

[0051] It will be appreciated that the power source 106 being capable of storage in a zero- volt state enables the power source 106 to remain with the heated garment during servicing, such as washing and drying, without risk of shorting the battery or any portion of the garment. In some embodiments, the zero-volt state of the power source 106 enables the heated garment to be launderable and / or submergible.

[0052] Without being bound by theory, any suitable power source 106 is contemplated and possible. Exemplary power sources 106 include those disclosed in U.S. Patent Nos.11,309,544, 11,165,065, and 10,700,386, and those containing cathode materials disclosed in any of U.S. Patent No.6,855,461, U.S. Patent No. 6,921,609, U.S. Patent No.7,381,496, U.S. Patent No. 9,209,455, U.S. Patent No. 9,391,31, U.S. Patent No. 11,158,853, or U.S. Patent No. 10,501,335, the contents of each of which are incorporated by reference herein in their entireties.

[0066] As described briefly above, in some embodiments, the heated textile architecture 100 and / or the various components of the management circuit 300 may be coupled to and / or directly integrated into a fabric base layer 10. The fabric base layer 10 is generally the foundational textile into which all components are integrated. In some embodiments, the fabric base layer 10 provides flexibility, breathability, and comfort while housing the heated textile architecture 100 without adding unnecessary bulk.

[0067] The fabric base layer 10 may be made from any suitable material for supporting the heated textile architecture 100, described in greater detail herein. In some embodiments, the fabric base layer 10 is a material that balances heat retention and moisture management. In some embodiments, the fabric base layer 10 has low thermal conductivity to trap body heat, while breathability ensures moisture control during high levels of exertion. Low thermal conductivity in a fabric refers to the material's ability to limit the transfer of heat through it. Fabrics with low thermal conductivity resist heat flow and are characterized by their ability to reduce heat exchange between the body and the environment. Breathability refers to the fabric’s ability to allow moisture vapor (such as sweat) to pass through its fibers. Breathable fabrics may draw moisture away from the skin and spread it across the fabric’s surface for faster evaporation. Exemplary fabrics with low thermal conductivity and breathability include merino wool, bamboo, silk, cotton-polyester blends, TENCEL®, nylon, polyester, blends of synthetic and natural fibers, combinations thereof, and the like.Docket No.57TIA12652WO / 209565-89

[0068] Optionally, the fabric base layer 10 is a low-profile textile. As used herein, a low- profile textile refers to a fabric that is designed to have a minimal bulk or thickness while maintaining functionality and comfort. In some embodiments, a low-profile textile is designed to reduce volume of garments for layering purposes.

[0069] Optionally, the fabric base layer 10 is chosen for tactile characteristics (e.g., soft hand fabrics), resilience, breathability, ventilation, and / or moisture-wicking properties. In some embodiments, the fabric base layer 10 is a 4-way stretch material, such as spandex, spandex blends, microfiber, jersey knit, neoprene, and the like. Alternatively, the fabric base layer 10 may be a grid construction knit. Optionally, the fabric base layer 10 is specifically designed to resist melting and / or dripping when exposed to high temperatures (i.e., a non-melt fabric or no-drip fabric according to ASTM D6413 and / or ASTM F1930).

[0070] In some embodiments, such as illustrated in FIG.6, the fabric base layer 10 may be fashioned into any suitable garment or article of clothing, including but not limited to, shirts, pants, underwear, socks, gloves, jackets, coats, hats, face masks, blankets, and the like, to form the heated garment 600. In some embodiments, such as when layering, the garment 600 may be the closest layer to the skin of the wearer. The heated garment 600 may be fit to the wearer’s body (i.e., garment measurements are close to body measurements) to keep the heated textile architecture 100 close to the body without shifting.

[0071] Optionally, the various components of the management circuit 300 may be discreetly integrated into the garment 600. The controller 302, power source 106, sensor 306, and / or other component(s) are optionally placed inside seam allowances, hidden in stitches, or placed in hems or pockets for integration. Optionally, the heated garment 600 is submersible or launderable.

[0072] In some embodiments, the user input 308 is placed on the heated garment 600 such that the user input 308 is easily accessible to the wearer. For example, and without being bound by theory, in embodiments where the heated garment 600 is a shirt, the user input 308 may be embedded into the sleeves of the shirt, such as on the wrist area or in the cuff of the shirt. In other embodiments, the user input 308 may be embed in the collar of the shirt to allow easy access to the user input 308.Docket No.57TIA12652WO / 209565-89

[0073] The heated textile architecture 100 is optionally positioned within the garment 600 such that the heated textile architecture is near targeted areas on the wearer’s body for supplemental warmth and / or cold protection. Optionally, one or more heated textile architecture(s) 100 are located in a chest, shoulder, upper arm, forearm, back, lower back, neck, wrist, upper leg, lower leg, midsection, head, forehead, or other desired location in the heated garment 600, or a combination thereof.

[0074] Various aspects of this disclosure are illustrated by the following non-limiting examples. The examples are for illustrative purposes and are not a limitation on any practice of the disclosure. It will be understood that variations and modifications can be made without departing from the spirit and scope of the disclosure. EXAMPLES Example 1

[0075] The recharging capabilities of a Li-ion pouch cell, combining a graphite-lithium nickel oxide (gLNO) cathode with a high-rate lithium titanate oxide (LTO) anode were evaluated at -50 °C.

[0076] Voltage vs. capacity measurements were performed at various current rates, including 0.6A, 3A, 6A, 8A, and 10A, to assess the charging and discharging efficiency, the results of which are depicted in FIG. 4. The results demonstrated that the cell could be recharged effectively even at -50°C, a temperature at which conventional lithium-ion cells typically experience significant capacity loss or complete failure.

[0077] These findings suggest that the gLNO / LTO pouch cell is capable of maintaining recharging functionality at extremely low temperatures. This ability to sustain functionality at extreme temperatures highlights the potential for these cells in applications requiring reliable energy storage in extremely cold environments. Example 2Docket No.57TIA12652WO / 209565-89

[0078] A 2.5 Ah pouch cell containing a CAM-7®cathode (CAMX-Power) and a lithium titanate anode (Ishihara Sangyo Kaisha LT-106) was subjected to 1,000 full charge-discharge cycles to assess its long-term durability. Despite undergoing such a high number of cycles, the battery cell demonstrated no capacity fade and maintained consistent room-temperature charge and discharge characteristics. Additionally, the battery was stored in a fully discharged, zero- volt condition for 33 months.

[0079] The data, shown in FIG.5, demonstrates stable charge and discharge characteristics across these rates, indicating robustness in both energy delivery and recharging processes. Notably, the battery retained its capacity and voltage profile even after extensive cycling.

[0080] This extended cycle life and zero-volt tolerance highlight the advanced electrochemical stability and design flexibility of the battery, making it a suitable candidate for demanding applications where deep discharge or prolonged storage is expected. Its ability to withstand zero-volt conditions for extended periods without significant degradation positions it as a reliable energy storage solution. Example 3
