Lithium batteries are generally use lithium manganese dioxide as positive pole material, metal or its alloy metal anode materials for batteries, the use of water electrolyte solution. Discharge reaction: Li + MnO2 = LiMnO2 lithium ion battery: the lithium ion battery is usually USES lithium alloy metal oxide anode material, graphite as the cathode material, using nonaqueous electrolyte battery. Charge on a positive reaction for LiCoO2 = = Li (1 -) x CoO2 + XLi++ Xe - (electronic) charge is happening on the cathode reaction is 6 c + XLi++ Xe - = LixC6 rechargeable batteries overall reaction: LiCoO2 + 6 c = Li (1 -) x CoO2 + LixC6 anode anode materials: many optional battery anode materials, mainstream products with lithium iron phosphate. Different cathode material control: LiCoO2 3.7 V 140 mAh/g Li2Mn2O4 4.0 V 100 mAh/g LiFePO4 3.3 V 100 mAh/g Li2FePO4F 3.6 V 115 mAh/g the positive reaction: embedded discharging lithium ion, charging lithium ion embedded. Charging: LiFePO4 - Li1 - xFePO4 + xLi + + xe - discharge: Li1 - xFePO4 + xLi + + xe - - > LiFePO4 cathode anode materials: use graphite more. A new study has found that titanate can be better materials. The cathode reaction: discharging lithium ion embedded, rechargeable lithium ion embedded. Charging: xLi + + xe - + 6 c - > LixC6 discharge: LixC6 - xLi + + xe - + 6 c
