基于同轴碳/四元氧化物复合负极构建柔性、集成的可充电锂电池
Construction of a flexible, integrated rechargeable Li battery based on a coaxial anode with a carbon fiber core encapsulated in FeNiMnO4 and a nitrogen-doped carbon sheath
摘要
Abstract
A coaxial anode with a carbon fiber core encapsulated in nanocrystalline FeNiMnO4 with a nitrogen-doped carbon sheath was prepared using carbon fiber cloth as the core, FeNiMnO4 nanocrystallite arrays as the first coating layer and nitrogen-doped carbon derived from F127 (a kind of triblock copolymer)-resorcinol-melamine gel as the outer layer. After annealing at 600℃ it was used as the anode material of an all solid flexible lithium ion battery using LiFePO4 as the cathode material and boron nitride modified polyethylene oxide as the electrolyte. The battery had a large areal capacity of ～1.40 mAh cm?2 and satisfactory cycling stability under different bending and strain states. Annealing below 600℃ leads to incomplete carbonization of the nitrogen-doped carbon and thus a low electrical conductivity while above 600℃ aggregation of FeNiMnO4 nanocrystallites and their detachment during cycling are observed under bending and strain.关键词
