Lithium-Ion Battery

Rechargeable electrochemistry

Lithium-ion batteries use intercalation in anode and cathode materials; ions shuttle through electrolyte during charge and discharge.

Inputs

Electrical energy during charging drives ions from cathode to anode.

Process

During discharge, ions move back to the cathode through electrolyte while electrons flow through the circuit.

Outputs

Electric power delivery; over cycles, capacity slowly declines due to side reactions.
