This product is designed for home energy storage system integrators and residential energy equipment manufacturers, effectively addressing core industry pain points including high thermal runaway risk of traditional batteries, short cycle life, fast capacity attenuation, and poor customization compatibility. Our products strictly follow international safety and performance standards, with core technological breakthroughs in intelligent battery management system (BMS) design and high-consistency cell assembly. To date, our products have been applied in dozens of countries and regions, with performance verified in scenarios including residential energy storage, commercial and industrial energy storage, portable power supplies, and backup power systems. The products have obtained multiple international authoritative certifications, and are recognized as a high-reliability technical solution in the global energy storage sector.
Home energy storage LiFePO4 battery is a type of secondary rechargeable battery that uses lithium iron phosphate as the cathode material, carbon material as the anode, and lithium salt organic electrolyte as the electrolyte, realizing energy storage and release through the intercalation and deintercalation of lithium ions between the cathode and anode. Developed based on core technologies including independent cell screening and intelligent BMS management, it can achieve stable charge and discharge, long cycle life, and high safety performance under various application scenarios. As a core component in the new energy energy storage sector, it has become an indispensable technical support for residential photovoltaic energy storage and backup power systems.
To meet the diversified needs of different application scenarios, our home energy storage batteries cover the following mainstream series, and provide customizable technical solutions for special scenarios:
1. Standard Residential Energy Storage Series: Positioned for residential photovoltaic supporting energy storage, with core features including long cycle life and maintenance-free operation.
2. Customized Adaptation Series: Positioned for home energy storage systems with special size or voltage requirements, with core features including flexible customization and compatibility with mainstream energy storage inverters.
The core working principle of the home energy storage LiFePO4 battery is based on the reversible intercalation and deintercalation reaction of lithium ions in the lithium iron phosphate material, paired with intelligent BMS dynamic management. The complete implementation logic is as follows:
1. During charging, lithium ions are extracted from the lithium iron phosphate cathode, embedded into the anode carbon material through the electrolyte, to store electric energy.
2. During discharging, lithium ions are extracted from the anode and returned to the cathode, releasing electric energy to supply household loads. The intelligent BMS monitors the voltage, current, and temperature of each cell in real time, dynamically adjusting the charge and discharge strategy to avoid overcharge, over-discharge, and abnormal temperature conditions.
Compared with traditional lead-acid batteries commonly used in home energy storage scenarios, our technology has achieved core breakthroughs as follows:
1. Traditional lead-acid batteries have a cycle life of only 300-1000 times, while our LiFePO4 batteries have a cycle life of ≥2000-5000 times, reducing the full life cycle cost by more than 60%.
2. Traditional batteries have a high risk of thermal runaway, while our products have good thermal stability, are not prone to fire, and have significantly improved safety performance.
All parameters of our home energy storage batteries are tested in strict accordance with international test standards, with clear test conditions and strict tolerance control. We can provide full parameter test reports for each batch of products, and support third-party authoritative testing.
