Abstract

Zinc metal batteries are promising candidates for multiple energy storage applications. Zinc dendrite formation is one of the major factors inhibiting their implementation, and multiple directions have been explored to mitigate this. MXenes are 2D transition metal carbides with the structure Mn+1XnTx. MXenes have high conductivity with hydrophilic, redox-active terminations, which makes them prime candidates in energy storage applications. MXenes (mainly Ti3C2Tx) have established use in Zn battery dendrite suppression as a coating on the Zn metal or an electrolyte additive. There is considerably less work on using MXenes as an anode-free electrode, which would maximize energy density and zinc utilization, warranting exploration.
