Progress in Rechargeable Aqueous Alkali-Ion Batteries in China

Rechargeable aqueous batteries, which are promising candidates for safe and large-scale energy storage, have attracted considerable attention in the past decade. Recently, rechargeable aqueous alkali-metal-ion (Li+, Na+, and K+) batteries (AAIBs) have emerged as a frontier research field that has led to many new aqueous alkali metal batteries. This review focuses on research and development pertaining to AAIBs in China, classifying and analyzing current publications based on the topic, the regional distribution, and the affiliations, summarizing the well-reported electrode materials and the recently emerged concentrated electrolytes. This review provides a comprehensive overview of the progress in rechargeable AAIBs in China and provides an outlook for designing durable high-voltage aqueous batteries.
