Which types of cells are rechargeable ?

Explanation

### Step-by-Step Solution

1. **Understanding Rechargeable Cells**:
- Rechargeable cells, also known as secondary cells, are types of electrochemical cells that can be charged and discharged multiple times. Unlike primary cells, which are designed for single-use, rechargeable cells can restore their original chemical composition after discharging.

2. **Discharge Process**:
- During the discharge process, a rechargeable cell converts stored chemical energy into electrical energy. This process generates discharge products that may deposit on the electrodes.
