Jun 04 2025Why do lithium iron phosphate batteries dominate the home energy storage market?
As the global demand for renewable energy surges, lithium iron phosphate batteries (LiFePO₄) have become the absolute mainstream of home energy storage systems. But why can this type of battery beat other options such as lead-acid batteries and ternary lithium batteries? The following analyzes the reasons from the perspective of technical advantages and practical applications.
1. The core advantages of lithium iron phosphate batteries
(1) High safety，Not prone to fire and explosion
The thermal runaway temperature of lithium iron phosphate batteries (LiFePO₄) exceeds 270°C, which is much higher than that of ternary lithium batteries (about 60°C). This means that in extreme cases such as overcharging, short circuit or physical impact, lithium iron phosphate batteries will hardly catch fire or explode, which perfectly meets the stringent safety requirements of home scenarios.
(2) Long cycle life, longer service life
The cycle life of lithium iron phosphate batteries (LiFePO₄) can reach 4,000 to 6,000 times, which is 3-6 times that of lead-acid batteries (300-500 times) and ternary lithium batteries (1,000-2,000 times). Based on one charge and discharge per day, its service life can easily cover more than 10 years, and the long-term use cost is significantly lower than other battery types.
(3) Strong stability, suitable for extreme use environments
Whether in extremely cold environments of -20°C or high-temperature areas of 60°C, lithium iron phosphate batteries (LiFePO₄) can operate stably. This feature makes it particularly suitable for China's large north-south span and diverse climate scenarios, while providing reliable support for overseas energy storage markets (such as Northern Europe and the Middle East).
(4) Excellent environmental performance, conducive to sustainable development
Lithium iron phosphate batteries do not contain scarce metals such as cobalt and nickel, which not only avoids the damage to the environment caused by mining, but also avoids the risk of price fluctuations of raw materials. Its materials are 100% recyclable, in line with the global carbon neutrality goal, and are a truly green energy storage solution.

2. Significant defects of other batteries
Lead-acid batteries: bulky, short life (only 3-5 years), and risk of sulfuric acid leakage.
Nternary lithium batteries (NCM/NCA): high energy density but poor thermal stability, with great safety risks.
Lithium titanate batteries (LTO): Although the life span is more than 10,000 times, the cost is high and it is only used in special fields.
In contrast, lithium iron phosphate batteries (LiFePO₄) achieve a perfect balance between safety, life, cost and environmental protection, becoming the "gold standard" for home energy storage systems.
With the popularization of distributed energy sources such as photovoltaics and wind power, household energy storage batteries need to balance efficiency and reliability. Lithium iron phosphate batteries (LiFePO₄) have been widely used around the world, demonstrating their excellent performance from urban household rooftop photovoltaics to off-grid systems in remote areas. In the future, with the iteration of technology and the reduction of costs, its dominant position will be further consolidated. Whether it is to configure a "self-generation and self-use" energy system for the family or to pursue a long-term and stable power supply, lithium iron phosphate batteries (LiFePO₄) are the only choice that takes into account safety, life and cost-effectiveness.
