摘要：

Stabilized lithium metal powder (SLMP) can effectively compensate the irreversible capacity, increase energy density in the continuous charge-discharge process of lithium-sulfur battery, and provide more anode materials to match the need of the energy market in the future. A novel SLMP anode in which hard carbon (HC) was used as the additive and poly-vinylidene fluoride (PVDF) as binder was prepared in an argon-filled vacuum glove box. The new negative sheet provides greater surface for electrolyte infiltration, facilitates ion diffusion and improves the utilization of sulfur element. This new type of Li-S battery has a higher initial capacity of 1300.9 mAh/g and a better cyclic stability than cell using conventional lithium foil as anode. (C) 2015 Elsevier B.V.
