Abstract
In the pursuit of convenient and healthy lives, human body electronic devices with interactive, medical, and communication functions have been gradually developed, propelling research into high-safety aqueous batteries as energy hubs. Despite extensive research progress, the application of aqueous batteries in human body electronic devices is still at the proof-of-concept stage. In this Focus Review, we comprehensively summarize the design strategies and research advances in the rational coupling of electrochemical properties with mechanical properties, degradability, and biocompatibility for aqueous wearable and implantable degradable batteries. The challenges and perspectives for the further development of aqueous batteries for human body electronic devices are outlined to guide research toward next-generation aqueous batteries for practical applications in the human body.
