摘要：
A bio-inspired nanofibrous polypyrrole/silicon composite derived from natural cellulose substance was synthesized. Due to its unique porous network structure and PPy coating on the silicon fibres, it showed improved reversible capacity, cyclability and rate capability upon long-term charge/discharge cycling when employed as an anode material for lithium-ion batteries.
