Research on the Application of Alkaline Zinc-Cobalt Secondary Batteries in Deep Space Exploration
In the field of deep space exploration,which represents the new frontier of human scien-tific inquiry,stringent demands are placed on power supply systems.Currently,lithium-ion batteries are commonly used as backup power sources for solar arrays.However,in the extreme environments encountered during deep space missions,lithium-ion batteries suffer from limitations such as low energy density and high safety risks.Therefore,there is a need to search for an alternative battery system.Alkaline zinc-cobalt secondary batteries have attracted considerable attention as an emerg-ing energy storage technology due to their high theoretical capacity and high operating voltage.They can provide continuous power supply under conditions of prolonged poor sunlight,and their high safety performance can reduce the risk of accidents.However,the main challenges currently faced include low utilization of active materials and severe self-discharge.In this study,we optimized the mass-charge-transfer characteristics to improve the utilization of cobalt-based cathodes in zinc bat-teries.Meanwhile,effective suppression of self-discharge was achieved by enhancing charge transfer.This research demonstrates the potential advantages of alkaline zinc-cobalt secondary batteries in deep space exploration and lays the foundation for exploring more advanced energy storage systems.It promotes the development of deep space exploration missions and provides new opportunities for humanity to better understand the universe.
