435mAh/g(Journal of the Chemical Society chemical Communications, 2012,48,
3321).Such material have huge development potentiality, but its in charge and discharge process as electrode volume expansion caused by
The variation of electrode material structure can cause the decaying of battery capacity, to restrict its development.In addition, metal oxide, titanate,
Organic matter etc. also can be used as the negative electrode material for sodium-ion battery.
Higher and higher as the requirement of energy storage device to sodium-ion battery with the research and development of new energy, people thirst for
Develop high-energy-density, long circulation life and the sodium ion negative electrode material for preparing the features such as simple.
