A new high capacity cathode material for Li/Na-ion batteries: dihafnium sulfide (Hf₂S)

Abstract

Structural and electronic properties of newly synthesized monolayer dihafnium sulfide (Hf2S) was investigated in this study. Hf2S monolayer is a magnetic metal and it retains its metallicity despite external factors...

Exploring the potential of MB2 MBene family as promising anodes for Li-ion batteries

“…The specific capacity is higher than that of several reported anode materials, such as graphite (372 mA h g −1 ), pillared MnO 2 (588 mA h g −1 ), 64 Ti 3 C 2 (488 mA h g −1 ), 60 and Nb 2 CS 2 (194.36 mA h g −1 ). 5 What's more, the specific theoretical capacity is comparable to that of graphene monolayer (1116 mA h g −1 ), 65 Hf 2 S (1378 mA h g −1 ) 66 and BN-doped reduced graphene oxide (BN-rGO) (1583 mA h g −1 ). 67 They are expected to become negative electrode materials for LIBs in the future.…”

A novel 2D VC4 as a promising Na-host material for Na-ion batteries: computational insights

“…[1][2][3] Recent studies have indicated that cathode materials used in LIBs exhibit comparable properties when applied to SIBs. [4][5][6] However, due to the weak binding ability between Na + and graphite, the commercial anode material (graphite) for LIBs becomes electrochemically inactive for SIBs. [7][8][9][10] Numerous studies have been conducted to optimize carbon-based materials' properties for enhancing their Na + storage performance.…”
