柔性锂金属电池用无枝晶生长的碳基复合锂电极
Dendrite-free carbon/lithium metal anodes for use in flexible lithium metal batteries
摘要
Abstract
Flexible energy storage devices are of great importance for the rapid growth of flexible electronic devices. Metallic lith-ium is considered a core anode material in high energy density rechargeable batteries because of its high theoretical specific energy density, the lowest redox potential, and high mechanical flexibility. However, safety issues and a short cycle life induced by lithium dendrites restrict the practical uses of lithium metal batteries. Here we described a nitrogen-doped graphene/lithium metal composite as an anode, in which the Li metal nucleation and growth was guided by doped heteroatoms in the graphene framework. Dendrite-free plating/stripping behavior was detected on the composite anode and its use in flexible lithium-sulfur batteries was validated.关键词
