Abstract
Alloy-type anodes hold significant promise for potassium-ion batteries (PIBs) due to their high theoretical capacities and good cycling stability. However, their utilization is severely limited by poor electronic conductivity and large volume expansion, which can limit their electrochemical performance. Recent studies have shown nanostructured materials can mitigate volume expansion and improve potassium storage in alloy-type anodes. This chapter reviews recent advances in alloy-type anodes for PIBs with focus on electrode design, improvement strategies, underlying mechanisms, electrolytes and cathodes compatibility, and future directions. It meticulously evaluates existing research challenges, providing crucial insights for developing high-performing PIB anodes.
