The Working Principle Of The Lithium Battery

Lithium battery:

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: Li + MnO2 = LiMnO2

Lithium ion battery:

Lithium ion batteries are generally use lithium alloy metal oxide anode material, graphite as the cathode material, using nonaqueous electrolyte battery.

For the charge on a positive response

LiCoO2 = = Li (1 -) x CoO2 + XLi++ Xe - (electronic)

For the charge on a negative reaction

6 c + XLi++ Xe - = LixC6

Rechargeable batteries overall reaction: LiCoO2 + 6 c = Li CoO2 + LixC6 (1 - x)

The anode

The anode materials: many optional battery anode materials, mainstream products with lithium iron phosphate. The positive materials of the different control:

The positive reaction: discharging lithium ion embedded, charging lithium ion embedded. Charging: LiFePO4 - Li1 - xFePO4 + xLi + + xe - discharge: Li1 - xFePO4 + xLi + + xe - - > LiFePO4.

The 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
