 Iron phosphate lithium

I.  Brief introduction to products
Characteristics: dark grey powder, accordant color, no     impurity and caking.
Advantages:
1. High density of the energy : specific capacity>140 mAh/g.
2. High security: It is the safest cathode material for lithium battery at present, no harmful heavy metal, and the battery assembled with this material won’t explode when over charged and discharged, and won’t be hot when quickly charged and discharged.
3. Long cycle life, more than 1000 Charge-Discharge Cycle Counts under 100 % DOD condition.
4. No memory effects.
5. Steady physical and chemical characteristics between different batches
 
Application: Cathode material for lithium- ion battery
Packaging: two-seal HDPE. 20kg/ barrel.
Attention to storage and transport: Store in dry and ventilated warehouse; no humidity; avoid acid mist, rain and strong sunlight and being stored and transported with food and combustibles; handle with care to avoid packing breakage.
