  • Patent number: 11522212
    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.

A first bond between the anode current collector and the anode coating layer may have a first adhesion strength. The battery cell also includes a cathode, a separator layer that contacts the cathode, and a separator coating layer. The separator coating layer can be positioned between the anode coating layer and the separator layer. A second bond between the separator coating material and the anode coating material has a second adhesion strength. The second adhesion strength of the second bond may be greater than the first adhesion strength of the first bond.

  • Patent number: 11271253
    Abstract: Various arrangements for creating a cylindrical anti-dendrite anode-free solid-state battery are presented. An anti-dendrite layer may be layered between an anode current collector layer and the cathode layer. A layered stack may be created that comprises a dry separator layer, a cathode layer layered with a cathode current collector layer, and the anti-dendrite layer layered with the anode current collector layer. The layered stack may be rolled into a cylindrical jelly roll. The rolled layered stack may be inserted into a pouch. A liquid electrolyte mixture may be added into the pouch. The liquid electrolyte mixture can permeate the dry separator layer. Heat can be applied to the pouch that causes the liquid electrolyte mixture to become a gel. The rolled layered stack can then be removed from the pouch and inserted into a cylindrical battery cell canister.

  • Publication number: 20210104747
    Abstract: A battery cell having a cathode, an anode, an electrolyte, and a dendrite absorber material. The dendrite absorber material reacts with lithium dendrite that forms on the anode after cycling the battery cell through charging and discharging cycles. The dendrite absorption material interacts with the lithium dendrite via lithium fusion. As a result of the lithium fusion, the dendrite absorber forms a lithium alloy and prevents expansion of the dendrite past the dendrite absorber material within the cell battery. This helps prevent short-circuiting between the anode and cathode due to lithium dendrite, which would cause performance degradation and safety issues such as fires.
