11. LiFePO4 olivine
structure
NCM layered
structure
Thermal decomposition test of
different types of Li-ion batteries
The thermal decomposition
temperature of NCM is
lower than 200 ℃ , and
oxygen is generated during
decomposition, which is
easy to burn and catch fire;
The decomposition
temperature of LiFePO4
material is 250 ℃ , and no
oxygen is generated during
decomposition.
VS
Stable structure and high safety
Olivine structure, P-O bond is stable and
difficult to decompose. Even at high
temperature or overcharge, it will not
collapse or produce strong oxidizing
substances, and the structural stability is
excellent.
Long life
LiFePO4 ：3000~10000
cycles
NCM：500~2000 cycles
Low cost and rich resources
Rich in raw material resources, free of
precious metal elements and low price,
it is the first choice for high safety and
low-cost power batteries.
High safety LFP cell
Product advantages

12. Ultra long cycle life ：
More than 90% of the capacity remains after 1000
cycles.
Excellent discharge performance ：
The maximum discharge rate of more than 30C can
improve the ignition voltage, increase the ignition
efficiency and save fuel.
