A low-cost bio-mass-derived carbon substrate has been employed to synthesize MoS 2 @carbon composites through a hydrothermal method. Carbon fibers derived from natural cotton provide a three-dimensional and open framework for the uniform growth of MoS 2 nanosheets, thus hierarchically constructing coaxial architecture. The unique structure could(More)
As a promising Li-metal battery, Li-S battery has an ultrahigh theoretical energy density of 2600 Wh kg-1. However, most of the previous work has mainly focused on tackling the "polysulfide shuttle" originating from the S cathode, while the dendrite problem coming from the Li-metal anode has often been overlooked. Herein, to solve the issues arising from(More)
Owing to its ultrahigh specific capacity and low electrochemical potential, lithium (Li) metal is regarded as one of the most attractive anode materials for next-generation lithium batteries. Nevertheless, the commercialization of Li-metal-based rechargeable batteries (LiMBs) has been retarded by the uncontrollable growth of Li dendrites, as well as the(More)
