AI Technical Summary
Existing lithium-ion batteries have poor thermal management performance under different climatic conditions, resulting in shortened lifespan and safety issues. Traditional aerogel materials cannot achieve effective heat preservation and heat dissipation at the same time.
By employing a thermally tunable aerogel layer, the thermal conductivity is changed through compression and recovery states. Combined with a liquid cooling plate, active regulation of battery temperature is achieved. The difference in thermal conductivity of the aerogel under different compression states is utilized to control heat transfer.
It enables wide-range and continuous adjustment of battery temperature, improving the working efficiency and lifespan of the battery pack, and ensuring the safety and stable performance of the battery in all seasons and over a wide temperature range.
