Abstract
The ongoing surge in demand for energy conversion and storage spurs the development of high-efficiency batteries. In recent decades, aqueous alkaline batteries (AABs) have been the focus point owing to the high safety, low cost, environmental benefits, impressive output voltage and theoretical energy density. However, the large-scale application of AABs is hindered by the poor cyclability and insufficient capacity utilization, especially in anodes. To circumvent the issues, great research efforts have been dedicated to the electrode design and electrolyte optimization. In this review, reaction mechanisms, modification strategies, application feasibility and existing challenges are systematically summarized and highlighted. Additionally, insightful perspectives and research orientations are proposed for further development of AABs anodes.
