A review of thermal physics and management inside lithium-ion batteries for high energy density and fast charging

Traditionally it has been assumed that battery thermal management systems should be designed to maintain the temperature around room temperature. That is not always true as lithium-ion (LIB) R&D pivoting towards development of high energy density and fast charging batteries. Therefore, necessary have a comprehensive review considerations for LIBs targeted charging, i.e., optimal condition, physics (heat transport generation) inside battery, strategies. As charge rate increases, can shift higher than In first part various sources heat generation approaches minimizing are summarized. The importance mixing due ion diffusion during also highlighted. To improve uniformity avoid excessive internal rise, transfer needs enhanced, reducing contact resistance between electrodes separator significantly increase effective conductivity second challenges latest developments related properties discussed. Finally, summary advancement on smart control discussed depending ambient temperature; retained or dissipated elevate rise.
