- Challenges: Susceptible to damage from moisture absorption and environmental degradation.
3. Phase Change Materials (PCMs)
Phase change materials (PCMs) are substances that absorb or release heat as they transition between solid and liquid states. These materials are particularly effective in regulating temperatures within EV batteries, as they can absorb excess heat during high-temperature periods and release it when temperatures drop.
- Advantages: Highly effective in stabilizing battery temperature, energy-efficient.
- Challenges: More expensive and complex to integrate into battery designs.
4. Polymeric Insulation Materials
Polymer-based materials, such as polyurethane and polyethylene, are also widely used in the EV battery insulation market. These materials are often chosen for their excellent thermal resistance properties and ease of processing into complex shapes.
