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.
