The successful one-step synthesis of few-layer Nb2CTx can facilitate its research and development in the fields of lithium ion batteries and related energy storage devices.
Ti3C2Tx, a new type of two-dimensional material, is a prospective anode material in lithium-ion batteries (LIBs) for its low lithium-ion diffusion barrier, high conductivity and many other excellent properties. In this paper, multilayer Ti3C2Tx and delaminated Ti3C2Tx samples are prepared by etching Ti3AlC2 powder with HF and [Formula: see text], respectively. We explore the application of the two samples in LIBs, and analyze their electrochemical behavior and kinetic mechanism. At the current densities of 0.1[Formula: see text]A[Formula: see text]g[Formula: see text], the delaminated Ti3C2Tx electrode delivered higher capacities of 255[Formula: see text]mAh[Formula: see text]g[Formula: see text] than multilayer Ti3C2Tx electrode (100[Formula: see text]mAh[Formula: see text]g[Formula: see text]). Even after 1000 cycles, the specific capacity of the delaminated Ti3C2Tx is still up to 205[Formula: see text]mAh[Formula: see text]g[Formula: see text] at 1[Formula: see text]A[Formula: see text]g[Formula: see text]. This work proves the great potential of the delaminated Ti3C2Tx for lithium-ion storage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
