锂离子电池用硅基材料的研究进展
Research progress of silicon material as anode for lithium-ion batteries
摘要
Abstract
Silicon materials are attractive candidates for the next generation of fithium-ion batteries due to their high theoretical specific capacities (4 200 mAh/g).However,the commercial use of silicon anodes has been hindered to date by their low cycle life and high initial capacity loss.To overcome the damage of the electrode from the targe volume change and thus obtain better capacity retention and cycle life for Si anodes,various approaches have been used: using nano-partictes,forming multiphase composites,fabricating thin film electrodes and alloys,using selected binders and electrolyte,operating vottage control,et al.Here,the methodologies adopted for reducing the capacity fade observed in silicon-based anodes were reviewed,the challenges that remained in using silicon and silicon-based anodes were discussed,and the possible approaches for overcoming them were proposed.关键词
