Comparison

Lithium iron phosphate battery LFP

Ternary lithium battery  Li(NiCoMn)O2

Cost

Low cost

Both phosphorus and iron are elements widely distributed in nature.

High cost

Because the positive pole material contains a rare metal cobalt.

High temperature capacity

High temperature capacity is good

Compared with normal temperature, the capacity of 55℃ at high temperature is unchanged, or even slightly increased.

High temperature capacity is generally

Under the condition of high temperature 55℃, there is little change, and the capacity will decrease slightly, usually about 99%.

Stability of material/safety

Stability of material is high

Thermal runaway temperature can reach about 500-800℃, so it is not easy to cause fire, high safety.

Stability of material is general

Thermal runaway temperature is usually about 200℃, flammable and explosive. Therefore, higher requirements are put forward for BMS.

Cycling time

Cycling life is long

The main cell cycle life is about 2000 times; Long cycle cell can reach more than 6000 times.

Cycling life is general

The main cell cycle life at room temperature is 800-1500 times, the main  cell that manufacturer usually promise more than 600 times.
