Abstract:

Graphite has been widely used as the commercial anode of secondary ion batteries. Its current specific capacity nearly reaches to its theoretical value, which cannot satisfy the requirements of high-performance batteries. The anodes with high specific capacity, such as the metal in IA group as well as the elements in IVA or VA group, have attracted enormous attention, but the poor cycle performance and safety issues restrict their practical application. As a result, the framework-design strategy has been put forward. Carbon materials are the promising frameworks for the high specific capacity anodes of secondary ion batteries because of their extensive sources and adjustable properties. This paper reviews the applications of carbon frameworks in silicon-, phosphorus-, germanium- and tin-based anodes as well as Li and Na metal anodes from the aspects of pore structure, specific surface area, electronic conductivity, ion conductivity, heteroatom doping and interface modification, and puts forward the outlook for the development of carbon supports.

Key words: Carbon framework, High specific capacity, Anode, Secondary ion battery
