The degradation of battery negative electrode materials in protic ionic liquids

The battery is an electrochemical device that people use every day. The industry is always interested in improving different characteristics of batteries such as less cost, increasing power, safety, and eco-friendliness. Nickel metal hydride (NiMH) batteries are widely used rechargeable power sources. We work on the replacement of aggressive electrolyte used in this technology by a more ecofriendly ionic liquid (IL). The proposed project is focused on the study of the negative electrode materials degradation in a new electrolyte. It is important for the good long time performance of the battery. Using different techniques we will study the degradation of materials during the charge/discharge cycling of the electrode materials. Also, this project is planned to study calendar corrosion. It is necessary to study the degradation of materials at storage mode because for example more than 90% of a car’s lifetime is spent parked and unused. This project will help us to choose good candidates for a new electrolyte.
