Product Description
Lithium Iron Phosphate (LiFePO₄, abbreviated as LFP) batteries are a type of lithium-ion battery that uses lithium iron phosphate as the cathode material. Distinguished from other lithium-ion battery chemistries (such as lithium cobalt oxide, LiCoO₂), LFP batteries exhibit unique characteristics that make them highly suitable for specific lighting applications. Their core advantages include excellent thermal stability, long cycle life, high safety, and environmental friendliness—traits that directly address the critical requirements of emergency lights, explosion-proof lights, and solar lights.

1. High Safety: The LiFePO₄ chemistry offers exceptional thermal and chemical stability. Its olivine structure inherently minimizes thermal runaway risk, making it resistant to fire or explosion. The battery pack typically includes protection circuits (or BMS) for protection against overcharge, over-discharge, and short circuits, offering safety superior to some other lithium-ion batteries.
2. Long Cycle Life: High-quality LiFePO₄ batteries offer a very long cycle life. Well-maintained cells can achieve over 2,000 cycles (to 80% of initial capacity). This translates to over 4 years of service with one cycle per day, making them cost-effective in the long run.
3. Wide Temperature Adaptability: Emergency lights may operate in harsh environments, from cold warehouses (-20°C) to hot industrial facilities (60°C). LFP batteries perform reliably within a temperature range of -20°C to 60°C, whereas lead-acid batteries often lose capacity in low temperatures and degrade quickly in high temperatures.
4. Environmental protection and ease of use: They are free of heavy metals like cobalt and lead, non-toxic and non-polluting, making them more environmentally friendly. They have no memory effect, allowing convenient recharging at any time without needing a full discharge.
