Hollow structures derived from metal-glycerates toward efficient electrochemical energy storage and conversion

Abstract

Hollow structures derived from metal-glycerates (MGs) are of particular interest for efficient electrochemical energy storage and conversion (EESCs) applications because they offer distinctive structural features, such as rapid transport paths and internal voids, making them highly promising as materials for electrodes or electrocatalysts. This review systematically summarizes recent advances in various MG-derived hollow structures and their exceptional performance in EESC systems. First, the rational design of various MG-derived hollow structures, including single-shelled, core-shelled, yolk-shelled, double-shelled, and multi-shelled hollow configurations, are introduced. Then, the diverse EESC applications of MG-derived hollow structures, including supercapacitors, metal-ion batteries, lithium-sulfur batteries, and key electrocatalytic processes such as hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reaction are systematically discussed, with a particular focus on the underlying structure-property relationships. Finally, insights into the major challenges and prospective solutions for the application of MG-derived hollow structures in EESCs are provided, aiming to inspire further advancements in this promising research field.
