Understanding Heat Generation in Lithium Batteries
1. Internal Resistance
Every battery has some level of internal resistance, which generates heat when current flows through it. Higher currents lead to more significant heat generation.
| Current (A) | Internal Resistance (Ohms) | Heat Generated (W) |
|---|---|---|
| 10 | 0.05 | 5 |
| 20 | 0.05 | 10 |
| 30 | 0.05 | 15 |
2. Charging and Discharging Cycles
During charging, lithium ions move from the cathode to the anode, releasing energy as heat. Similarly, during discharging, energy is consumed, which also generates heat.
| Cycle Type | Heat Generation Mechanism |
|---|---|
| Charging | Ions moving create resistance |
| Discharging | Energy release causes resistance |
3. Ambient Temperature Effects
The surrounding environment significantly impacts battery temperature. High ambient temperatures can exacerbate heating issues, leading to potential thermal runaway if not managed properly.
| Ambient Temperature (°C) | Battery Temperature Increase (°C) |
|---|---|
| 20 | +5 |
| 30 | +10 |
| 40 | +15 |
