摘要
铁镍二次电池的充电效率低和高倍率性能差,一直以来严重制约其快速发展~([1])。近年来,本课题组在新型铁镍二次电池负极材料的研究方面取得了一定进展~([2])。研究发现,FeS直接用作负极材料时表现优异的倍率性能和循环性能。在该研究基础上,近期,本课题组通过简单的共沉淀法成功制备出FeS/RGO纳米复合材料。该材料在不添加任何导电剂和电极填充量达到40mg/cm~2的情况下,能实现20C倍率的充放电,且循环性能优异。
For the first time,FeS nanoparticles anchored on reduced graphene oxide(RGO) nanosheets are synthesized via a facile,environmentally friendly direct-precipitation approach.As an alkaline battery anode,the FeS/RGO electrode delivers a superior high-rate charge/discharge capability and outstanding cycling stability,even at a condition of without any conductive additives and a high electrode loading of ~40 mg cm~(-2).By virtue of its superior fast charge/discharge properties,the FeS/RGO nanocomposite is suitable as an advanced anode material for high-performance alkaline secondary batteries.
