According to the development process of TR, its initial cause is that the SEI decomposition on the negative electrode surface leads to the reaction between negative electrode material and electrolyte. Thus, the performance of the negative electrode material plays an important role in the battery thermal safety.
The carbon negative electrode produces an exothermic reaction at about 100 °C–140 °C. Although it releases less heat than that from the positive electrode, it could still make the temperature of the battery reach 220 °C. In the meantime, oxygen would be released from the lithium metal oxide, resulting in TR of the battery.
When the temperature is higher than 180 °C, the negative electrode will begin to be decomposed, which will also cause heat accumulation and release flammable gas, and finally lead to the combustion even explosion of LIBs. In the process of TR, the ISC produces only 1/49 of the chemical reaction heat.
Therefore, improving the thermal stability of SEI is also an appropriate way to improve the safety of negative electrode. Mild oxidation, deposition of metals and metal oxides, coating of polymers and other types of carbon modification methods have enhanced the surface structure of the graphite anode .
The electrochemical performance of graphite is relatively stable; The actual specific capacity density is close to the theoretical one, which is the main reason why graphite has been widely used as negative electrodes . Fig. 9 shows the energy storage mechanism of anode materials for LIBs. Fig. 9.
In the process of high temperature or repeated charging, the collapse of electrode material structure would cause that of the battery . Different types of carbon materials also have different safety performances.
