1. As a lithium ion secondary battery, lithium iron phosphate battery has a cycle life of more than 2000 times, which is much longer than lithium manganate battery.
2. Lithium iron phosphate battery is still stable at 600℃, but lithium manganate battery is much worse.
3. Lithium manganate batteries are expensive, while lithium iron phosphate batteries are much cheaper.
4. Lithium ferrous phosphate will not ignite and explode when it is overcharged to 100%; The lithium battery will deflate and expand when it reaches the specified value.
Characteristics of lithium iron phosphate battery: lithium iron phosphate battery can be used whenever it is charged, no matter what state it is in, and it does not need to be discharged before charging. However, lithium ferrous phosphate has low tap density and compaction density, low battery yield and poor consistency.
Characteristics of lithium manganate battery: Lithium manganate battery is a battery with lithium manganate as the positive electrode, and its nominal voltage reaches 3.8V, which is the mainstream power battery at present. This battery has medium energy density, average life, safety and environmental protection, and no patent restrictions.
Sanyuanli battery system &; The difference between ternary lithium battery and lithium iron phosphate battery in lithium iron phosphate battery system: lithium iron phosphate battery is more resistant to high temperature and ternary lithium battery is more resistant to low temperature; Ternary lithium batteries are more efficient than iron phosphate batteries; The cycle life of lithium iron phosphate battery is better than that of ternary lithium battery.
