还原氧化石墨烯微观结构调控及储钠性能研究
Study on Microstructure Regulation and Sodium Storage Performance of Reduced Graphene Oxide
摘要
Abstract
The development of efficient anode materials for carbon-based sodium ion batteries(SIBs)is a hot research topic.The prereduced graphene oxide(GO)was annealed at different temperatures to obtain wavy reduced graphene oxide(rGO)with different interlayer spacings for sodium-ion batteries(SIBs)anodes,and the electrolyte was further regulated to explore the relationship between the microstructure of graphene and sodium storage performance and sodium storage mechanism.The rGO anode after balancing the tuning layer spacing and conductivity shows a high initial coulombic efficiency of 82%in SIBs and excellent cycle stability of 93%capacity retention after 100 cycles through the sodium storage mechanism of intercalation and solvation Na+ co-adsorption in ether electrolyte.关键词
