Project summary description:
This project aims to develop proton batteries with higher energy density that are capable of stable operation at ultralow temperatures. Based on a first proposed all-phosphate electrodes-electrolyte configuration, this project develops a new category of transition metal phosphate electrodes and promotes their capability of fast charging and discharging at ultralow temperatures. The project develops methods to suppress side reactions, enabling high-voltage output of the proton batteries. The project is expected to provide an advanced understanding of the electrochemical process in the proton batteries.

In previous research, proton batteries have limited energy density due to the relatively low voltage output. This project aims to develop high-voltage proton batteries with higher energy density capable of stable operation at ultralow temperatures. The project outcomes include a new category of transition metal phosphate electrodes and an advanced understanding of the electrochemical process in proton batteries. The preparation and application of the new materials and proton batteries in this project do not involve chemicals or processes that can have a negative environmental impact.
