State-of-the-art Li-ion batteries (LIBs) degrade in delivered capacity and lifetime if charged repeatedly under extreme conditions such as high current or at low temperature. This project is investigating new methods to meet the challenge of charge under extreme conditions using a combination of approaches. Modification of electrode materials, electrode design, as well as electrode/electrolyte interfaces are being used to improve battery behavior under fast charge and charge at low temperature conditions. Methodology used to accomplish the project goal includes construction and electrochemical testing of pouch cell batteries as well as material and interface characterization.
