| Abstract: | Research progress in porous silicon-based anode materials for Li-ion batteries was reviewed, focusing on the effects of their morphology and compound on the electrochemical properties. The reasons of poor cycling performance are analyzed. It is pointed out that to control the huge volume change and SEI growth during the cycling is an effective way for improvement of the performance. Outlook for the future development of porous silicon composite anode materials and further research of designing porous structure based silicon nanocomposites for the application of silicon anodes are finally outlined. |
