Air and liquid are used as media to transfer heat to the battery. Air preheating with a low thermal efficiency needs a large space due to poor thermal physical properties [15] and is not suitable for the preheating requirements of highly integrated battery packs. Liquid preheating has a higher heating rate than air preheating.

The Development of Flexible Batteries for Future Electronics

The requirements for flexibility vary from application to application. A flexible battery for cell phones (thickness: 3 mm) is expected to suffer a minimal strain of 5% when bent (radius of 30 mm) (Liao et al. 2019 ). Most flexible battery applications aim to achieve a trade-off between flexibility and performance.
