Lithium iron phosphate Basic Attributes

Molecular Weight ：157.76

EC Number ：476-700-9

Characteristics

1. high energy density its theoretical specific capacity of 170mAh / g, the actual specific capacity of the product can exceed 140mAh / g (0.2C, 25 ° C);

2. safety is currently the safest lithium-ion battery cathode material; does not contain any heavy metal elements harmful to the human body;

3. long life in 100% DOD conditions, can be charged and discharged more than 2,000 times; (Reason: lithium iron phosphate) Good lattice stability, lithium ion embedding and detachment of the lattice has little effect, so it has good reversibility. The shortcomings are poor electron-ion conductivity, unsuitable for high-current charging and discharging, hindered in the application. Solution: electrode surface coating Chemicalbook conductive materials, doping for electrode modification.)

4. No memory effect

5. charging performance lithium iron phosphate cathode material lithium batteries, you can use a large times the rate of charging, the fastest in 1 hour to fill the battery. Specific physical parameters: loose packing density: 0.7g/cm vibration density: 1.2g/cm medium particle size: 2-6um specific surface area <30m/g coating parameters: LiFePO4:C:PVDF=90:3:7 pole compacted density: 2.1-2.4g/cm electrochemical properties: gram capacity>155mAh/g test conditions: half-cell, 0.2C, voltage 4.0-2.0V cycle times: 2000 times.

Lithium iron phosphate Use

Batteries using lithium iron phosphate cathode materials can be widely used in many fields due to the innate structural stability characteristics of lithium iron phosphate, especially in terms of safety and cycling performance with unparalleled advantages.
