Ultra-thin solid electrolyte interphase evolution and wrinkling processes in molybdenum disulfide-based lithium-ion batteries

MoS2 is a highly promising anode material for lithium ion batteries. Here, aided by atomic force microscopy, the authors reveal the formation of an ultra-thin solid electrolyte interphase between MoS2 and electrolyte, providing fresh insight into the structural evolution and reaction mechanism at the interface.
