Advantage of li ion battery
- High voltage platform. The higher the voltage platform, the greater the specific capacity. Certainly the same volume, weight, and even the same ampere-hour battery. The ternary material lithium battery with a higher voltage platform has a longer range. The voltage platform of the ternary material is obviously higher than that of lithium iron phosphate, the high line can reach 4.2 volts, and the discharge platform can reach 3.6 or 3.7 volts.
- High energy density
- High tap density
Disadvantage of li ion battery
Poor high temperature resistance
Advantage of LiFePO4
longer life cycles. The lithium iron phosphate power battery has a cycle life of more than 2000 times, and can be used up to 2000 times with standard charging (5 hour rate).
Disadvantage of LiFePO4
1. The tap density of the positive electrode of the lithium iron phosphate battery is small, and the density is generally about 0.8 to 1.3.
2. Poor conductivity, slow diffusion rate of lithium ions, the actual specific capacity is low when charging and discharging at high power.
3. The low temperature performance of the lithium iron phosphate battery is poor.
The life of a single battery of lithium iron phosphate battery is long, about 2000 times, but the life of lithium iron phosphate battery pack is short, generally about 500 times.
