In situ fabrication of nanohybrid carbon/polyamide film providing robust binding and conductive network in silicon anode for lithium-ion battery

Engineering of a composite electrode containing Si-based anode materials is important for the practical applications of Si-based lithium-ion batteries. In this work, a hybrid composite anode of silicon/carbon/polymer was fabricated in situ by optimized heat treatment of the coating slurry containing silicon power and polyamic acid polymer, without adding any carbon agent. The resulting electrode has a three-component (silicon-carbon-polyamide)...
