Abstract
The widespread demand for battery-powered technologies has propelled the search for efficient and commercially viable electrode materials with fast-charging abilities. Reported herein is an MoS2-expanded graphite (EG) composite as a stable and high-rate lithium-ion battery (LIB) anode, delivering specific capacities of 796 mAh g-1 at 0.5 A g-1 and 320 mAh g-1 at 20 A g-1 over 400 cycles. Cyclability at extreme rates up to 50 A g-1 (~103 mAh g-1) illustrates its scope for fast charging applications. As a result of the processing technique, the exfoliated nanosheets have good interfacial contact which aids in charge transfer and maintaining structural integrity during continuous battery operation. Further, analytical electrochemical methods suggested a predominance of pseudocapacitive charge storage mechanism, explaining the anode performance at high rates.
期刊介绍：
Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics.
Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews.
A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal.
Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
