Novel two-dimensional tetragonal vanadium carbides and nitrides as promising materials for Li-ion batteries

Abstract

We demonstrate that tetr-V2C2 and tetr-V2N2 monolayer sheets exhibit low Li diffusion barrier, high theoretical capacity and low average open circuit, suitable as anode materials for lithium ion batteries.

Effects of polyacrylic acid molecular weights on V2C-MXene nanocoatings for obtaining ultralow friction and ultralow wear in an ambient working environment

“…7,8 As a distinguished energy storage material, MXenes possess high mobility of carriers, a rich electronic structure, and an adjustable layer spacing. [9][10][11] Commonly, titanium carbide MXene (Ti 3 C 2 -MXene) 12,13 and vanadium carbide (V 2 C-MXene) 14,15 are two of the most researched MXenes in materials and chemicophysics. As one of the several representative pioneering works, Liu found that Ti 3 C 2 -MXene was capable of accelerating the formation of a lubricative tribofilm on the contact interface in oil.…”

Electrochemical Investigation of Interfacial Properties of Ti3C2Tx MXene Modified by Aryldiazonium Betaine Derivatives

“…During the last few years, MXenes have played an ever important role in terms of both crystalline and composition varieties for catalysis (Zhang et al, 2018 ; Benchakar et al, 2019 ; Li and Wu, 2019 ; Sun et al, 2019 ), environmental applications (Rasool et al, 2019 ), development of Li batteries (Ostadhossein et al, 2019 ; Wu Y.-Y. et al, 2019 ), and (bio)sensors (Kalambate et al, 2019 ; Lorencova et al, 2019 ; Mohammadniaei et al, 2019 ; Wu Q. et al, 2019 ; Gajdosova et al, 2020 ; Szuplewska et al, 2020 ).…”

The Thermoelectric Properties of Monolayer MAs2 (M = Ni, Pd and Pt) from First-Principles Calculations

“…It is well known that the successful peeling of graphene greatly promotes the exploration of two-dimensional (2D) layered materials. The special physical, chemical, electronic and optical properties exhibited by the two-dimensional materials make it have good application prospects in the fields of electrodes [ 9 , 10 ], nano devices [ 11 ] and TE technology [ 12 ]. Hicks and Dresselhaus proposed that ZT value would be improved if 2D structural materials were used instead of three-dimensional ones [ 13 , 14 ].…”
