Compact Carbon‐Based Ultra‐High‐Power Electrodes: A Sodium Alginate‐Induced Self‐Shrinkage and Densification Approach (Small 21/2025)

High‐Power Electrodes In article number 2407475, Guowen Meng, Bingqing Wei, Fangming Han, and co‐workers unveiled a sodium alginate induced self‐shrinkage densification strategy for crafting compact, all‐carbon electrodes. This strategy enhances specific surface area, electronic conductivity, and ion transport rate of carbon‐based electrode. Consequently, the electrode in aqueous electrolyte demonstrates an outstanding power performance, marking a milestone for advanced compact, ultra‐high‐power electrodes.
