How It Works ยท Science
Lithium-Ion Battery
Rechargeable electrochemistry
Lithium-ion batteries use intercalation in anode and cathode materials; ions shuttle through electrolyte during charge and discharge.
- anode
- cathode
- electrolyte
- separator
- cycle life
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.

Why it matters
Climate Resilience
Climate resilience reduces damage from climate-related hazards and speeds recovery.
Comparison
Mitosis vs Meiosis
Mitosis makes matching cells for growth and repair, while meiosis creates sex cells and introduces genetic variation.
Examples
Osmosis
Osmosis is water diffusion through a semipermeable membrane toward higher solute concentration.
