Components of a Lithium-Ion Battery
A lithium-ion battery consists of several key components, including:
| Component | Description |
|---|---|
| Lithium Cobalt Oxide (LCO) | The positive electrode (cathode) of the battery, responsible for storing lithium ions. |
| Graphite | The negative electrode (anode) of the battery, responsible for storing lithium ions. |
| Electrolyte | A chemical substance that facilitates the flow of lithium ions between the electrodes. |
| Separator | A thin layer of material that separates the electrodes and prevents electrical shorts. |
| Current Collector | A metal tab that connects the electrodes to the external circuit. |
Manufacturing Process of Lithium-Ion Batteries
The manufacturing process of lithium-ion batteries involves several stages, including:
Stage 1: Material Preparation
In this stage, the raw materials are prepared for use in the battery. This includes:
