How Lithium-Ion Batteries Work – The Science Behind It
A lithium-ion battery is a rechargeable electrochemical device that stores and releases energy by the movement of lithium ions between two electrodes: the anode and the cathode, via an electrolyte.
Core Components and Their Functions:
| Component | Function | Common Materials |
| Anode (-) | Stores lithium ions during charging | Graphite, Lithium Titanate (LTO) |
| Cathode (+) | Stores lithium ions during discharge | Lithium Cobalt Oxide (LCO), NMC, LFP |
| Electrolyte | Allows ion transport between electrodes | Lithium salt in organic solvent |
| Separator | Prevents short-circuiting | Polyethylene (PE), Polypropylene (PP) |
| BMS | Controls charging/discharging cycles | Digital microcontrollers + sensors |
The Charge/Discharge Cycle:
- Charging: Lithium ions move from cathode → anode and are stored.
- Discharging: Lithium ions flow back from anode → cathode, releasing energy to the device.
Key Battery Performance Metrics:
