LFP Lithium iron phosphate Carbon coated Battery grade

High energy density: Its theoretical specific capacity is 170mAh/g, and the actual specific capacity of the product can exceed 150mAh/g (0.2C, 25°C)(new model can reach 160mAh/g).

1. 
   

2. Safety: It is currently the safest lithium-ion battery positive electrode material; it does not contain any heavy metal elements that are harmful to the human body.
   

3. Long life: Under 100% DOD conditions, it can be charged and discharged more than 2000 times; (Reason: Lithium iron phosphate has good lattice stability, and the embedding and extraction of lithium ions have little effect on the lattice, so it has good reversibility. The disadvantage is that the electronic ion conductivity is poor, which is not suitable for large current charging and discharging, and hinders in application. Solution: Coat the conductive material on the electrode surface and dope it to modify the electrode.)
   

4. No memory effect
   

5. Charging performance: Lithium batteries with lithium iron phosphate positive electrode materials can be charged at a high rate, and the battery can be fully charged in 1 hour at the fastest.
   

6. The core methods of lithium iron phosphate modification are carbon coating (low cost, high conductivity) and metal doping (high energy density), supplemented by nano-sizing to improve kinetic performance. Industrial production focuses on the combination of solid phase method and carbon coating, and future technology will focus on composite modification and optimization of ultra-thin coating layers.
