Free-standing molybdenum disulfide/graphene composite paper as a binder- and carbon-free anode for lithium-ion batteries

摘要: Abstract Two dimensional nanosheets, such as graphene and metal disulfides, have attracted a great deal of attention anode materials for lithium-ion batteries, owing to their unique capability storage. In this work, we integrate MoS 2 nanosheets into free standing film form using simple vacuum filtration method. As-prepared composite could be readily employed binder- carbon-free removing the polymeric binders conductive carbon additives that are required preparation conventional electrodes. addition, interconnected structure sheets provide good electrical conductivity entire electrode. When tested electrochemical performance an electrode exhibits superior compared exfoliated electrode, 65.8% capacity retention at high current rate 1000 mA g −1 91.1% after 100 cycles.
