Flexible and Anti-freezing Cu@Fe3O4-PANI/Polyvinyl Alcohol/Phytic Acid/LiCl Hydrogel Electrolytes in High-Performance All-Solid-State Supercapacitors
The widespread adoption of flexible electronics has driven the development of all-solid-state energy storage materials. However, the limited single-functionality and unsatisfactory low-temperature tolerance of conventional hydrogel electrolytes remain critical challenges for wearable applications. Thus, a Cu@Fe3O4-PA...
