Description

Technical Field

[0001] This invention belongs to the fields of new energy storage technology, power energy storage technology, energy-saving energy storage and magnetic field-assisted voltage regulation technology. Specifically, it relates to a composite long-lasting energy storage technology based on the principle of physical magnetic energy stabilization and solidification, combined with a rubber-like sealed inner liner that can be arranged inside and outside, high-temperature sealing, and vacuum liquid nitrogen injection and vaporization. It is applicable to the fields of power batteries, static energy storage power stations, high and low temperature outdoor energy storage, new energy power generation supporting energy storage and energy-saving and environmentally friendly power equipment technology. Background Technology

[0002] Existing commercial energy storage batteries, such as lithium iron phosphate and ternary lithium batteries, all rely on pure electrochemical oxidation-reduction reactions to achieve energy storage and release, which has inherent technological shortcomings.

[0003] Existing technologies have many shortcomings: 1. Electrochemical energy storage relies on the active energy storage of materials. After long-term charge and discharge cycles, the materials are prone to pulverization, agglomeration, and activity degradation, resulting in irreversible capacity decay and limited service life, making it difficult to achieve long-term solid-state energy storage. Traditional batteries lack a physical stable and fixed electrical structure, resulting in disordered escape of ionized charges within the cavity, high self-discharge rate, large fluctuations in voltage and current output, and poor energy storage performance when left undisturbed for a long time. Conventional batteries are prone to internal heat buildup, large-area overheating of the casing, and continuous temperature rise when charging, operating under high current, or in high-temperature environments in summer. High temperatures can accelerate the oxidation of internal materials, electrolyte evaporation, and structural aging, posing safety hazards such as thermal runaway and spontaneous combustion. Traditional battery protection often uses equipment to pump room-temperature gaseous nitrogen for filling. However, the filling and replacement are incomplete, there is a lot of residual air and moisture in the dead corners of the cavity, the gas purity is low, the airtightness is poor, the protection level is low, and it cannot achieve full-area pure inert protection. Existing nitrogen protection technology can only achieve basic oxygen isolation and does not have bidirectional constant temperature capability. It cannot lock in temperature and prevent heat accumulation at high temperatures, nor can it prevent freezing and stabilize capacity at low temperatures. In sub-zero environments, the internal substrate is prone to solidification, the electrolyte thickens, and the battery cell freezes, resulting in a sharp drop in battery capacity, inability to start normally, and serious power supply instability. 6. Conventional batteries do not have a dedicated flexible sealing structure, and the sealing gaps are prone to air leakage and moisture absorption. With long-term use, the protection fails quickly and the durability is poor.

[0004] Among the publicly available energy storage patents and industry technologies, no solution possesses an integrated and complete technical architecture that combines: high-temperature sealing with a rubber-based inner liner, deep vacuum, direct injection of liquid nitrogen for natural vaporization, physical magnetic energy for stable and solid electricity, and bidirectional high and low temperature protection.

[0005] This invention is completely different from traditional gaseous nitrogen filling protection technology. It has created a unique liquid nitrogen liquid injection phase change protection system, combined with a physical magnetic energy stabilization and solidification structure, to create a brand-new energy storage technology system that is not hot at high temperatures, does not freeze at low temperatures, maintains constant temperature all year round, stabilizes voltage and solidifies electricity, and is resistant to aging and safe. Summary of the Invention

[0006] The purpose of this invention is to overcome the technical deficiencies of existing energy storage devices and provide a physical magnetic energy stabilization and solid-state energy storage adaptation scheme, constructing a brand-new four-in-one energy storage system that integrates "chemical energy storage as the foundation, physical magnetic energy stabilization and solid-state energy storage, multi-functional auxiliary material adaptation and optimization, high-temperature sealing and sealing + liquid nitrogen vaporization full-temperature range constant temperature three-dimensional protection for life extension". Core Original Principles

[0007] Based on electrochemical energy storage, this invention utilizes multi-form permanent magnets to construct a constant closed magnetic field inside the cavity. By relying on physical magnetic field force to constrain free charges, solidify the electric field, and regulate the current flow, it stabilizes the output voltage and current from a physical perspective, firmly locks in the stored energy, reduces self-discharge, stabilizes the energy storage capacity, and suppresses performance degradation, thus achieving the core objectives of stable, solid, and long-term energy storage.

[0008] Meanwhile, this invention features a unique and exclusive sealed protection process: the battery cell is fully encased in a rubber-based inner liner → all seams and gaps are sealed with high-temperature hot-melt sealant → deep vacuuming is performed to remove air and moisture → liquid nitrogen is injected in a measured amount → the liquid nitrogen naturally heats up, vaporizes, expands, and fills the cavity → the outer shell is pressed together for permanent sealing.

[0009] This invention is completely different from the traditional air-filling and nitrogen-filling process in the industry: the traditional technology uses external equipment to pump ready-made gaseous nitrogen into a non-complete vacuum chamber, resulting in a large amount of residual nitrogen, low purity, and poor protective effect; this invention directly injects liquid nitrogen into a vacuum environment, which naturally vaporizes due to the temperature of the chamber itself. There is no external air-filling or external gas mixing, and the replacement purity can reach over 99%. There is almost no residual impurities in the chamber, and the airtightness, purity, filling uniformity, and temperature stability effect surpass traditional air-filling technology.

[0010] The high-purity inert gas formed after liquid nitrogen vaporization envelops the entire battery cell, achieving bidirectional constant temperature protection: in high-temperature conditions, it isolates heat accumulation, suppresses temperature rise, is flame-retardant and does not support combustion, and prevents high-temperature aging and thermal runaway; in sub-zero cold conditions, it locks in the internal temperature, blocks the intrusion of external cold air, prevents the internal substrate from solidifying and freezing, and avoids low-temperature hardening failure of the battery cell, achieving constant temperature and voltage stability and stable power storage under all operating conditions in spring, summer, autumn and winter. Overall structural composition

[0011] The entire system is integrated within a single sealed energy storage enclosure, and is deployed as a single unit, including: 1. Positive electrode energy storage layer and negative electrode energy storage layer; 2. Multifunctional composite substrate: mica, conductive carbon black, activated carbon, diatomaceous earth, layered and zoned gradient formulation; 3. Full-domain magnetic energy stabilization and solidification system: permanent magnet fine powder full-domain filling, side wall permanent magnet strips, gap permanent magnet blocks, and through-type hollow copper magnetic tubes; 4. Multi-gradient formulation system, suitable for static, dynamic, high load, and high and low temperature complex working conditions; 5. Can be internally and externally arranged with rubber-like one-piece molded sealed inner liner, high temperature sealing sealed structure, and vacuum liquid nitrogen injection vaporization three-dimensional constant temperature protection system. Material Function Adaptation Instructions

[0012] 1. Mica: Balances the electric field, provides insulation and voltage stabilization, prevents localized breakdown, and stabilizes the layer structure; 2. Conductive carbon black: Constructs a dense conductive network to ensure smooth charging and discharging; 3. Activated carbon: Adsorbs electrolyte impurities, inhibits polarization, and delays aging; 4. Diatomaceous earth: Absorbs moisture and stabilizes temperature, balances the internal microenvironment, and improves environmental tolerance; 5. Multi-morphological permanent magnets: Construct a constant closed magnetic field to achieve charge locking, stable electricity, stable current output, and inhibit self-discharge; 6. Rubber-based sealed inner liner: Contains butyl rubber and various flexible elastic rubber materials, uniformly manufactured into standard cubic and cuboid structures, with high elasticity, strong airtightness, resistance to electrolyte corrosion, and resistance to high and low temperatures. It can be used to internally encase battery cells or externally cover the shell, and can adapt to the expansion and deformation caused by liquid nitrogen vaporization; 7. Liquid nitrogen: A liquid low-temperature inert medium that naturally vaporizes into an ultra-high purity inert gas within the vacuum chamber, possessing multiple properties such as heat insulation, constant temperature, flame retardancy, oxygen isolation, corrosion prevention, anti-condensation, and anti-aging. Complete and exclusive assembly process

[0013] 1. First, the energy storage cell assembly is neatly assembled and shaped; 2. The cells are completely encased in a rubber-based inner liner. After encasing, all seams, edges, and corners are sealed with high-temperature hot-melt sealant to completely block any tiny air gaps, forming a completely sealed, independent, flexible cavity; 3. A deep vacuum is performed on the sealed cavity through a pre-set air nozzle interface to completely remove air, moisture, and impurities, creating a high-vacuum sealed environment; 4. Liquid nitrogen is injected directly and quantitatively under high vacuum conditions without using any air pump or connecting to an external source of gaseous nitrogen; 5. The liquid nitrogen heats up naturally based on the cavity's temperature, completely transforming from a liquid to a gaseous inert gas, expanding uniformly and filling the cavity without any dead zones; 6. The elastic adaptive deformation of the rubber inner liner is used to match the vaporization pressure, ensuring uniform and stable internal pressure; 7. Finally, the outer shell is pressed and sealed, and the interfaces are permanently sealed, completing a fully sealed, high-purity, inert, constant-temperature protective structure. Full-temperature-range bidirectional constant temperature core protection principle

[0014] 1. Core function in high-temperature operating conditions The high-purity inert gas produced by liquid nitrogen vaporization does not store heat, accumulate heat, support combustion, or participate in electrochemical reactions. It can evenly distribute the heat generated by the battery cell during operation, prevent local high-temperature accumulation, continuously balance the internal temperature of the cavity, and avoid the battery from getting hot during charging or the casing from becoming too hot to touch.

[0015] The inert environment completely isolates oxygen, eliminating high-temperature oxidation, high-temperature evaporation of electrolyte, and high-temperature pulverization and degradation of materials. It eliminates the risk of thermal runaway, fire, and spontaneous combustion from the root. Combined with the magnetic energy structure, it stabilizes the power output, achieving high-temperature stable power, high-temperature anti-aging, and high-temperature safety protection.

[0016] 2. Core function in low-temperature operating conditions Inert gases have extremely low freezing points and uniform temperature conduction, maintaining a stable gaseous state even in extremely cold environments down to -30 degrees Celsius. This effectively prevents extreme external temperatures from penetrating the cavity, slowing down internal temperature loss and preventing electrolyte thickening, substrate solidification, and cell freezing. The high-purity nitrogen gas, after vaporization, has extremely stable physical and chemical properties, only liquefying at around -195 degrees Celsius, and maintaining a stable gaseous state under normal extremely cold operating conditions down to -30 degrees Celsius. Because the cavity is pre-vacuumed to thoroughly remove water vapor and impurity gases, there is no freezing medium inside, so there will be no freezing, frost or solidification in extremely cold environments. It can effectively block the conduction of external low temperature into the inside, slow down the loss of heat inside the cell, maintain a relatively constant internal temperature, avoid electrolyte thickening and cell activity reduction, and ensure stable and stable operation in low temperature environments.

[0017] It can maintain a relatively constant temperature range inside the cavity, preventing the battery capacity from plummeting at low temperatures, internal resistance from soaring, starting power failure, and power supply fluctuations. Relying on the magnetic field to lock in the power, it can achieve normal voltage stabilization and power storage and stable power output in extremely cold environments. Description of the adjustable three-dimensional protective structure

[0018] This invention provides a rubber inner liner that can be installed internally or externally, supporting free switching between single-layer simple protection and three-layer three-dimensional superimposed protection: for general scenarios, a single-layer vacuum liquid nitrogen protection is used, which is simple in process and low in mass production cost; for harsh scenarios such as high temperature and high load, extreme cold outdoor, and high corrosion, a three-layer three-dimensional protection is used, with the inner cell, middle cavity, and outer shell being synchronously inertly sealed, and the protection is superimposed layer by layer, ensuring the battery's stable power and service life in all dimensions. Beneficial effects

[0019] 1. Unique process, completely different from traditional nitrogen filling technology in the industry. This invention adopts high temperature sealing and vacuum liquid nitrogen direct injection and natural vaporization, which is not the traditional equipment for air filling and nitrogen filling. The medium form, process path, replacement purity and protection principle are completely different, which is highly novel and completely avoids existing patent barriers.

[0020] 2. Ultra-high purity replacement with minimal impurities and excellent airtight protection. Liquid nitrogen is injected into a vacuum environment, and the vaporization filling purity can reach over 99%. There is almost no air, water vapor, or impurities remaining in the cavity. The purity and uniformity of protection far exceed those of traditional air-filling processes, ensuring long-term airtightness without failure.

[0021] 3. Magnetic energy support enables stable, solid, and long-term energy storage. By relying on the physical magnetic field to lock the internal free charge, regulate the current flow, effectively reduce self-discharge, stabilize the output voltage and current, and firmly retain the stored energy. It is not easy to lose power or capacity when placed for a long time, and the energy storage stability is greatly improved.

[0022] 4. Full-temperature range bidirectional constant temperature, stable operation under all seasons, high temperature protection against heat accumulation and overheating, flame retardant and explosion-proof, and delays high temperature aging; low temperature protection against freezing and solidification of the medium, and avoids sudden drop in capacity at low temperatures, maintaining stable power supply and power storage in both high and low temperature environments.

[0023] 5. The sealing structure is robust and adaptable to flexible deformation. The rubber inner liner is combined with a high-temperature sealing process, ensuring a tight seal without leakage. It can adapt to the expansion deformation caused by liquid nitrogen vaporization, and the structure is stable and not easily damaged. The airtightness remains good even after long-term use.

[0024] 6. Wide range of applications, high safety factor, effectively avoids various failures such as thermal runaway, spontaneous combustion, corrosion, and moisture, and can be fully adapted to various application scenarios such as vehicle power supply, outdoor energy storage equipment, wind and solar energy storage power station, and industrial backup power supply.

[0025] 7. Raw materials are readily available, production costs are low, and mass production is easy. The rubber material, mineral substrate, permanent magnet material and liquid nitrogen medium used are all common materials on the market, with no technological monopoly. The assembly process is simple and efficient, and industrial mass production can be achieved quickly. Specific Implementation

[0026] 1. Long-lasting static energy storage ratio: High magnetic powder combined with high mica content, featuring low self-discharge, long-term solid energy storage, and maintenance-free daily use; 2. Balanced dynamic energy storage ratio: Balanced combination of magnetic materials and conductive carbon black, taking into account both total energy storage and dynamic discharge output stability; 3. High and low temperature adaptable energy storage ratio: Enhanced adsorption and temperature-stabilizing substrate ratio, specially adapted to complex outdoor operating conditions such as high temperatures in summer and extreme cold in winter.

[0027] All three implementation models are equipped with a high-temperature sealing and vacuum liquid nitrogen injection vaporization constant temperature protection process to comprehensively ensure the equipment's stable power storage performance and service life. Feature Summary

[0028] This invention is an independent and complete innovative technology system for magnetoelectric composite energy storage, which is completely different from traditional pure electrochemical batteries and traditional gaseous nitrogen filling and protection technology.

[0029] This invention features a unique high-temperature sealing and sealing process combined with a vacuum liquid nitrogen direct injection and natural vaporization ultra-high purity inert protection process. This, along with a full-domain physical magnetic energy stabilization and solid-state structure, achieves a bidirectional constant temperature and voltage stabilization effect, ensuring that the battery does not accumulate heat, become hot, age, or spontaneously combust at high temperatures, and does not freeze, lose capacity, or experience capacity loss at low temperatures. This completely solves the industry pain points of traditional energy storage devices, such as high temperature sensitivity, unstable output, limited energy storage time, short service life, and insufficient safety.

[0030] The entire technology is novel and unique in principle, original in processing technology, reasonable in overall structure, and highly feasible for mass production. It can be adapted to high and low temperature operating conditions in all scenarios and has extremely high creativity, practical application value and industrial promotion value.
