Application: Battery membranes and components thereof (Patent ID: US20240213623A1)
The patent filed by Rivian Automotive Inc. describes a battery cell with a cation-selective ion-exchange membrane that allows lithium ions to pass through while impeding manganese ions. The membrane can be made of various materials and have specific pore sizes and porosities to optimize its function.
The claims detail the specific configurations and materials of the membrane, as well as methods for reducing manganese ion concentration in the electrolyte using a voltage pulse. The membrane is positioned between the cathode and anode in the battery cell and can be disposed on a separator film. The patent emphasizes the importance of the membrane's ability to selectively transport lithium ions over manganese ions, with ratios ranging from 30:1 to 2:1. These features aim to enhance the performance and longevity of the battery cell in electric vehicles.
