Abstract

Abstract : In article number 1902086, Eric Detsi and co‐workers develop a Mg2 Ga5 alloy‐type anode with an extremely long‐cycle life of 1000 cycles, achieved at a relatively high (dis)charge rate of 3C, taking advantage of near‐room‐temperatures solid‐liquid phase transformations between Ga(liquid) and Mg2 Ga5 (solid) . This concept should open the way to the development of practical anodes for next‐generation magnesium‐ion batteries.
