For post-lithium batteries, carbon is still an opportunity as electrode materials, as hard carbons for anode purpose or as carbon fluorides as cathode one. Progresses in those fields will be rapid with the perfect mastery of electrochemical mechanisms and the use of characterization techniques coupled to galvanostatic cycling.

As the negative electrode material of LIBs, carbon materials have the advantages of low voltage, high safety, and low cost [ 133 ]. At the same time, the diversity of heat transport characteristics allows them to be used in different thermal fields, such as heat dissipation and thermal management.
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.
In the first place, the effects of carbon materials as electrodes on battery safety performance and electrochemical properties were summarized. Subsequently, the roles of each component during TR and the process were introduced, the importance of carbon materials was highlighted.
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 [ 93 ].
