Research Development of Preparation Methods and Properties of Si/C Nanocomposites Used for Cathode of Lithium-Ion Battery

The main preparation methods for Si/C nanocomposites used for cathode of lithium-ion battery in the last decade were introduced, including pyrolysis, chemical vapor deposition, milling, hydrothermal, gel method and so on. The microstructure characteristics of Si/C composite and their effects on specific capacity and cycling performance of composite were introduced, too. At last, the prospects of study direction of Si/C nanocomposites were showed.
