How does LiFePO4 technology work?
LiFePO4 technology uses lithium iron phosphate as the cathode material, providing excellent thermal stability and safety. During charging, lithium ions move from the cathode to the anode, and during discharge, they flow back, generating electricity. This process allows for high energy density and long cycle life while minimizing risks of overheating.
What are the advantages of using LiFePO4 batteries?
LiFePO4 batteries offer several advantages, including high safety, long lifespan (up to 6,000 cycles), and excellent thermal stability. They are environmentally friendly, with non-toxic materials, and provide high energy efficiency (over 95%). Additionally, they have low self-discharge rates and can operate effectively in various temperature conditions. LiFePO4 batteries offer several significant advantages:
- Safety: Low risk of thermal runaway compared to other lithium technologies.
- Long Cycle Life: Can last over 4000 cycles, making them cost-effective.
- High Efficiency: Excellent charge/discharge rates with minimal energy loss.
