Thermal Management in Battery Packs: Why It Matters
How heat affects lithium cells and what builders use to control it.
· 3 min read
Key takeaways
- Lithium cells age faster when hot.
- Thermal barriers slow heat spreading between cells.
- Aerogel sheets are used in modern EV packs.
Heat and battery life
Cells perform best in a moderate temperature window. Heat accelerates ageing.
Thermal barriers
Thin insulating layers between cells help stop one overheated cell from heating its neighbours.
For DIY builders
E-bike and power-station builders should follow cell manufacturer guidance and use proper BMS protection.
