报道了一种硒/微介孔碳球纳米复合物（Se/MPCS）双功能纳米结构电极材料。由于在MPCS基底中存在不寻常的链状Sen分子，Se/MPCS纳米复合材料在金属Li二次电池（即Li-Se电池）中表现出令人印象深刻的电化学性能。此外，通过将Se/MPCS阳极与传统的层状阴极耦合，构建了性能优异的新型锂离子全电池。采用Se/MPCS阳极组装的锂离子电池的新设计保证了良好的安全性、高容量和长寿命。
A bifunctional nanostructured electrode material of a selenium/micro–mesoporous carbon sphere nanocomposite (Se/MPCS) is reported. With the unusual chain-like Sen molecules hosted in a MPCS substrate, the Se/MPCS nanocomposite presents impressive electrochemical performances in metallic Li secondary batteries, i.e. Li–Se batteries. Furthermore, a new Li-ion full battery with remarkable properties is constructed by coupling the Se/MPCS anode with the traditional layered cathode. The new design of the as-assembled lithium-ion cell with the Se/MPCS anode promises good security and high capacity as well as a long lifespan.
