Abstract

Silver–zinc (Ag–Zn) batteries are one of the promising aqueous batteries to collect and store solar energy with high energy density, a stable output voltage, and being environmentally benign, but most Ag–Zn batteries have large contact resistance caused by polymer binders and conductive additives, thus leading to their low specific capacity and rate performance. As a proof-of-concept demonstration, we constructed a solar charged planar flexible quasi-solid-state aqueous rechargeable Ag–Zn battery using metal–organic framework (MOF)-derived Ag nanowires on carbon cloth as a binder-free cathode. Our electrochemical results show that the as-fabricated Ag–Zn battery has a remarkable energy density of 1.87 mWh/cm2 because MOF-derived Ag nanowires can provide abundant reaction sites and short electron and ion diffusion paths. Moreover, the as-fabricated Ag–Zn battery integrated with a solar cell can be charged by sunlight. Thus, our findings pave an avenue to develop solar energy-powered portable and wearable electronic devices.
