Hard Carbon for Na-ion Battery

Sodium ion batteries and lithium-ion batteries have similar principles and production processes, and sodium resources are widely distributed, in recent years has been widespread concern. Whether it is a lithium-ion battery or a Na-ion battery, the magnification performance is a key indicator of its performance. At present, sodium ion battery cathode material research and development has made important progress. However, for anode electrodes, the graphite electrode widely used in lithium ion batteries has no electrochemical performance in sodium ion batteries. Hard carbon material, also known as non-graphitizable amorphous carbon, is currently the best of many negative materials in the overall performance. Due to the high capacity of the material, stable cycle performance and a wide range of precursors, it will play an important role in the commercialization of sodium ion batteries. In recent years, with the different precursors, different structures and doping technology research, hard carbon as battery anode material, the performance has been further improved.
