Recent Progress on the Alloy‐Based Anode for Sodium‐Ion Batteries and Potassium‐Ion Batteries

Abstract High‐energy batteries with low cost are urgently needed in the field of large‐scale energy storage, such as grid systems and renewable energy sources. Sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs) with alloy‐based anodes provide huge potential due to their earth abundance, high capacity, and suitable working potential, and are recognized as attractive alternatives for next‐generation batteries system. Although some important breakthroughs have been reported, more significant improvements are still required for long lifetime and high energy density. Herein, the latest progress for alloy‐based anodes for SIBs and PIBs is summarized, mainly including Sn, Sb, Ge, Bi, Si, P, and their…
