Description

Technical Field

[0001] This invention belongs to the fields of novel solid-state derived energy storage, modular battery adaptation, and wide-temperature-range energy-saving energy storage technology. Specifically, it relates to a micro solid-state energy storage and battery adaptation method, which is applicable to various scenarios such as civilian energy storage, vehicle power supply, high-altitude and deep-sea power supply, and special power supply. It has a wide range of applications and outstanding adaptability. Background Brief

[0002] Currently, mainstream energy storage batteries are divided into liquid electrolyte systems and high-temperature sintered rigid solid-state systems, both of which have inherent drawbacks. Liquid batteries are prone to leakage and evaporation of the electrolyte, freezing at low temperatures, and aging and corrosion at high temperatures, leading to plate failure, cumbersome maintenance, and high pollution. High-temperature sintered batteries suffer from blocked powder pores, impaired electrochemical activity, inability to release deformation stress, increased internal resistance due to cracking, and difficulty in disassembling and regenerating materials. Conventional energy storage technologies struggle to simultaneously achieve wide-temperature operating stability, structural vibration resistance, reusability, and low-energy production requirements. There are currently no mature technologies on the market that can simultaneously address the shortcomings of both types of traditional batteries. This method abandons the two extreme forms of pure liquid and fully rigid solidification, adopting a micro-solidified powder energy storage mode, coupled with a differentiated electrochemical raw material system, to achieve flexible battery adaptation and upgrades, effectively compensating for the various shortcomings commonly found in existing technologies. Currently, no micro-solid-state energy storage technology solution has been found that simultaneously possesses room-temperature non-sintering molding, wide-temperature stability, removable powder replacement, and nitrogen inert protection, representing a long-standing technological gap in the industry. This method specifically addresses these industry pain points. Core Invention Concept

[0003] This method differs from previously submitted sponge-type energy storage material formulations by completely replacing the positive and negative electrode active powders, ion-conducting media, and binding and moisturizing components. It retains the room-temperature mixing, layered arrangement, flexible conductivity, modular assembly and disassembly, and internal nitrogen protection architecture. Instead of using a free-flowing liquid medium or high-pressure, high-temperature rigid sintering, it relies on a novel composite bonding system to form a loose, micro-solidified structure of the powder, preserving sufficient ion transport pores and deformation buffer space. Based on a completely new and independent electrochemical material system, it can flexibly adapt and assemble batteries according to the actual power and temperature scenarios. This solution completely breaks free from the technical constraints of traditional liquid and high-temperature solid-state batteries, pioneering a new technical route for powder micro-solidified energy storage, and represents a substantial innovation compared to existing publicly available technologies and the applicant's prior patents. Key technical features

[0004] Micro-consolidated energy storage body design Abandoning the liquid flow state and overall hardened structure, the newly formulated powder, after being adjusted at room temperature and lightly compressed, forms a stable, non-dispersible, and porous elastic micro-consolidated state. This eliminates leakage and freeze-thaw problems, while also buffering volume deformation during charging and discharging, ensuring smooth ion migration. Micro-consolidation, as defined here, refers to a special state in which the powder is shaped by a binding agent, without flowing or hardening, while retaining interconnected pores and a small amount of elastic deformation space. This is a novel intermediate structure distinct from traditional liquid, sintered solid, and loose powder energy storage.

[0005] A brand-new differentiated material system and precise formulation Breaking away from the original raw material categories such as lithium iron phosphate, biomass hard carbon, and silica sol, it selects brand-new electrochemical energy storage active materials, special ion-conducting ceramic powders, and high and low temperature resistant composite bonding media to construct the energy storage core. The electrochemical reaction system is substantially different from the prior patent. The material components are safe and non-toxic, without highly toxic heavy metals or harmful substances, and will not cause pollution hazards in production, use, or later recycling. The standard mass ratio of each functional layer is as follows: Positive electrode micro-consolidated energy storage powder layer: 62% vanadate composite energy storage powder, 25% manganese-based multi-element active powder, 10% iron-based pyrophosphate powder, and 3% magnetically doped modified micro powder; Negative electrode micro-consolidated energy storage powder layer: 70% modified pitch-based carbon powder and 30% tin-titanium composite oxide powder; Intermediate ion conduction and isolation powder layer: 42% magnesium oxide powder, 33% yttrium oxide ceramic powder, and 25% lithium silicate modified powder, which can be combined with ultrafine diatomaceous earth to adjust the permeability parameters; The micro-consolidated bonding medium is composed of aluminum-based composite inorganic colloid and modified borate colloid in a 55:45 ratio. The total amount of bonding medium added is 2.5%~4.5% of the total mass of the energy storage powder, which can be flexibly adjusted according to the molding tightness and operating temperature.

[0006] No heat treatment forming process The entire process of powder mixing, layering, conductive network laying, and sealing assembly is completed at room temperature. There is no sintering, drying, or high-pressure compaction, which preserves the original energy storage activity of the powder to the greatest extent. The production process is simple, low-energy, low-carbon and environmentally friendly, and the processing cost is highly controllable.

[0007] Layered core structure The energy storage core adopts a layered arrangement of positive electrode layer, ion isolation conduction layer, and negative electrode layer, combined with a multi-layer staggered flexible conductive network, which increases the conductive contact area, reduces the overall internal resistance, ensures uniform current distribution, reduces local heat loss, and ensures stable electrochemical reaction operation.

[0008] Nitrogen inert environment protection In existing technologies, nitrogen is mostly used only for the safety inertization, temperature control, or long-term storage oxidation prevention of finished batteries, and is not applied to the molding and preparation process of energy storage materials. This invention innovatively integrates nitrogen into the entire room-temperature micro-solidification molding process, providing inert protection simultaneously during powder placement, body shaping, and cavity sealing stages. This effectively avoids the problems of active material oxidation and deterioration, frequent electrochemical side reactions, and maintains stable pressure within the cavity. In this invention, nitrogen is a core component of the energy storage body manufacturing process, unlike traditional batteries where it is simply a complementary safety protection accessory. This effectively overcomes the industry's technical challenges of high energy consumption during high-temperature processing, easy structural cracking and damage, and the susceptibility to oxidation and failure of materials prepared at conventional room temperatures.

[0009] The sealed cavity is filled with nitrogen to isolate oxygen and external moisture, suppress the oxidation side reaction of the material, and greatly improve the structural stability of the micro-solidified core under extreme cold, high temperature and vibration environments, effectively slowing down the performance degradation rate of the energy storage material.

[0010] Global inert nitrogen pressure stabilization protection and wide temperature range adaptive adaptation The micro-solidified energy storage core is completely sealed inside a nitrogen-inert cavity, which maintains a slightly positive pressure nitrogen atmosphere, completely isolating it from oxygen, water vapor, and external corrosive impurities. In low-temperature environments, the non-freezing gaseous properties of nitrogen protect the pores of the micro-solidified powder from freezing, cracking, shrinkage, and blockage. In high-temperature environments, the inert and flame-retardant properties of nitrogen inhibit internal oxidation side reactions and eliminate the risk of thermal runaway. Combined with a brand-new high- and low-temperature resistant micro-solidified inorganic bonding system, the entire structure can stably adapt to a wide temperature range from -190℃ ultra-low temperature to 120℃ medium- and high-temperature operating conditions, with temperature tolerance performance far exceeding that of conventional energy storage products.

[0011] Flexible adaptation mode for multiple working conditions Depending on the usage requirements, a sealed heat insulation structure or a convection heat dissipation structure can be selected. The material ratio and assembly specifications can be adjusted according to the voltage, capacity and discharge parameters of existing technology equipment. It can be adapted to different types of products such as small portable power supplies, high-power industrial energy storage, and high-altitude and low-temperature special batteries, and is suitable for a wide variety of scenarios.

[0012] Detachable and reusable structure Adopting a modular structure with separate shell and material, the outer shell and conductive components can be reused, and the internal energy storage powder can be replaced and disposed of separately after its performance deteriorates. The waste material contains no highly hazardous or toxic components, and dismantling and recycling are simple and convenient, greatly improving resource utilization and aligning with the concept of green and circular development.

[0013] Core advantages compared to existing energy storage technologies Its form factor offers a balance of advantages and disadvantages, avoiding the defects of liquid and hard solidification. The micro-solidified structure is more stable, and its resistance to bumps and compression is better than that of conventional batteries. It is more suitable for outdoor mobile and vehicle-mounted applications, and its structure is less prone to damage and failure under complex conditions.

[0014] Wider temperature range With new temperature-resistant materials and nitrogen protection, it is not prone to clogging and failure at low temperatures, nor is it prone to decomposition and bulging at high temperatures. Its extreme environmental tolerance surpasses that of ordinary commercial energy storage batteries, breaking through the temperature limit of traditional batteries from -20℃ to 60℃.

[0015] Electrochemical performance steadily improved The new material system, combined with a porous conductive structure, enables energy storage capacity comparable to mainstream batteries of the same volume, with a longer cycle life, slower capacity decay over long-term use, and higher economic benefits over the service life.

[0016] Significantly improved safety and environmental friendliness It contains no highly corrosive liquids or hazardous heavy metals, poses no risk of leakage or fire during use, has low pollution emissions during production and disposal, meets the requirements of current green energy storage development standards, and is safe, environmentally friendly, easy to recycle, and free of residual toxicity throughout its entire life cycle.

[0017] Highly adaptable and versatile The entire assembly method allows for flexible adjustment of specifications and parameters, enabling it to adapt to various battery casings and electrical devices of different models. Its application scalability far exceeds that of single-type energy storage products, and it has great potential for industrialization and promotion.

[0018] Key points for distinguishing between the two prior patent applications At the material level: all core energy storage raw materials are completely replaced, with no overlapping components, and the formulation system is completely independent. At the naming and positioning level: micro-solidification is used as the core morphological identifier, focusing on battery adaptation and combination applications, forming a clear technical route to differentiate it from sponge-type loose energy storage. At the innovation focus level: prior patents focus on the characteristics of civilian general-purpose sponge energy storage, while this solution is biased towards differentiated material systems and compatibility with multiple battery models, effectively expanding the boundaries of technology application. At the protection level: each is an independent technical solution, which does not constitute redundant research and development, and can form a complete series of patent layouts, comprehensively building technical barriers, without any technical overlap or rights conflict.
