6 FAQs about [What materials are used for heat dissipation in battery cabinets]
Why is aluminum used in battery packs?
In lower-performance battery packs, aluminum has been the primary material, often used for mechanical structure and heat spreading. For higher-performance battery packs, the amount of aluminum needed for safe, efficient operation may result in a pack that is too heavy and bulky.
How to isolate battery cells to protect against heat propagation?
The primary strategies to isolate battery cells to protect against heat propagation all have pluses and minuses. Designing a battery module or pack requires balancing several competing thermal factors. The most common strategy is to provide just-enough thermal management to achieve the battery pack’s fundamental goals.
How to prevent thermal propagation in cell battery packs?
Spreading is the best way to prevent thermal propagation in pouch and prismatic cell battery packs because it prevents propagation while extending cell cycle lifetime and fast charging while cutting size and weight. Flexible graphite heat spreaders outperform aluminum and can support high-performance, small, lightweight battery packs.
What insulating material should be used to prevent heat transfer?
Combining different insulating materials such as aerogel, fiberglass, phase-change, mica, polyimide, ceramics, and air-gaps prevents heat from transferring. A minimum of 4mm to 6mm of insulation material is typically needed between cells to stop propagation.
Is graphite a good battery pack?
For higher-performance battery packs, the amount of aluminum needed for safe, efficient operation may result in a pack that is too heavy and bulky. Aluminum is dense and has poor thermal conductivity (200W/mK), but graphite is lightweight and has high thermal conductivity (400W/mK to 1,100W/mK).
