In this paper, the influence of different heating methods on thermal runaway of lithium-ion batteries was studied. Spring heating coils and cylindrical heating rods were used as heating devices to carry out thermal runaway experiments on 18,650 lithium-ion batteries with different SOC.
The heat radiation transmission of batteries may be influenced by the color variations of different films. Hence, in order to determine the specific heat capacity of the battery, it was imperative to eliminate any external components affixed to the battery’s surface.
It was found that, when the battery was under high SOC, the negative and positive electrode reactions contributed the most to the thermal runaway. Based on the principle of induction heating, kriston et al. used induction heating coil to induce thermal runaway of lithium-ion battery.
For the embedded heating elements, Wang et al. embedded nickel foil inside the battery and utilized the heat generated by the nickel foil to heat the battery. Although this method can heat the battery from −20 °C to 0 °C in 20 s, it requires a redesign of the battery structure and the effect on battery safety is not clear.

A primary contributor to the capacity degradation of LIBs at low temperatures is lithium plating . Therefore, it is important to avoid lithium plating during the low-temperature heating process.
