[Display omitted] •Micro-sized porous Si@PEDOT composite anode was synthesized.•NaOH etching of AlSi powder is prefer to HCl to maintain the micro morphology.•Si@PEDOT exhibited a high rate capacity of 1168 mAh g−1 at 2000 mA g−1. To address the serious volume expansion and poor conductivity of sili...
