Introduction
Wang et al. suggested a self-heating Li-IB (SHLB) design to heat the battery at low temperatures. The design contains a thin nickel foil of 50 μm inside the battery cell that has a resistance of 56 mΩ (Fig. 5 a). There are two tabs on this foil, one attached to the negative terminal and one extending outside as the activation terminal.
Zhu et al. conducted experiments to verify the state of health of batteries for 240 heating cycles. They reported that the temperature difference between the Li-IB was <2 °C even at a high discharge current, and there was no significant degradation in the battery.
Internal preheating of Li-IB Internal preheating refers to the process of heating the battery internally and can be divided into two groups. The first type, self-heating technology, preheats the battery utilizing cell energy.
