Research progress of coal based carbon anode materials in sodium-ion batteries
Considering the high dependence on foreign lithium resources in China,the development of sodium-ion batteries to partially replace lithium-ion batteries is of great significance to the safe,independent and sustainable development of China's energy storage business.Carbon materials have become the key anode materials to promote the industrialization of sodium ion batteries due to their ex-cellent structural stability,good electrical conductivity and high specific capacity.With the endowment of coal resources in China,it is of great significance to develop coal-based carbon materials and use them in sodium ion batteries to realize the high value-added utili-zation of coal resources under the background of carbon peaking and carbon neutrality.Based on this,this paper summarizes the appli-cation of coal-based carbon anode materials in sodium-ion batteries and their structural regulation methods,and indicates their future improvement directions.
