Mastering Electrocatalytic Microenvironment Achieves Aqueous Hydrogen Batteries Exceeding 200 Wh kg–1
High-safety, low-cost, and long-life aqueous hydrogen gas batteries (AHGBs) driven by hydrogen electrocatalysts are considered one of the most reliable systems in advanced aqueous batteries for large-scale energy storage. However, the rational design of low-loading and high-activity electrocatalysts remains a challen...
