Barsoum and Gogotsi’s report looks at intercalation of MXenes with a variety of ions, including lithium, sodium, magnesium, potassium, ammonium and aluminum ions. The researchers also reported on using MXene “paper” electrodes, instead of conventional rolled powder electrodes with a polymer binder. —Yury Gogotsi.

A team at the University of Maryland has demonstrated that a material consisting of a thin tin (Sn) film deposited on a hierarchical conductive wood fiber substrate is an effective anode for a sodium-ion (Na-ion) battery, and addresses some of the limitations of other Na-ion anodes such as capacity fade due to pulverization.
