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.

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.
