| Abstract: | The Si-based cathode for lithium ion batteries draw much attention for its high theoretical capacity,However,during the Li insertion,the volume expansion of the silicon lattice occured,and this resulted in cracking and disintegration of the electrode,which thereby showed the bad cycling performance and had hindered the silicon cathode from being commercialized.To overcome or alleviate these problems,the researchers have put up with many developed preparation processes to improve the initial discharge capacity and cycling performance.Here some developed preparation processes were summarized and the prospects of Si-based cathode for lithium ion batteries were pointed out. |
