  • Publication number: 20230335781
    Abstract: A battery cell having a layered pressure homogenizing soft medium for liquid/solid state Li-ion rechargeable batteries. The battery cell of the present technology includes one or more battery pouches, a pressure mechanism external to the battery pouches that applies a pressure to the battery pouches, and a layered pressure homogenizing soft medium that is displaced between the battery pouches and the pressure mechanism. By using a number of pressure homogenizing medium layers, each with a specific range of thickness and within a range of physical properties, the battery pouches displaced between the pressure homogenizing medium layers are evenly pressurized by the mediums due to pressure applied by the pressure mechanism to within a desired range of pressure. The pressure applied to the battery pouches by the pressure homogenizing medium is monitored by a pressure sensor, such as a two-dimensional pressure sensor.
