Towards high-volumetric performance of Na/Li-ion batteries: a better anode material with molybdenum pentachloride–graphite intercalation compounds (MoCl5–GICs)

MoCl₅–GICs are demonstrated as advanced anodes for simultaneously achieving high volumetric capacity and long cycle life in Na-ion and Li-ion batteries, owing to a strong charge transfer chemical doping effect and strong interaction force between MoCl₅ and graphite layers.
