Abstract: Energy storage devices, battery cells, and batteries may include a battery cell component that may be or include a ceramic layer produced by methods including admixing a ceramic with a water-soluble dispersant to form a first mixture. The methods may include admixing an organic polymeric dispersant with the first mixture to form a second mixture. The methods may include admixing a binder with the second mixture to form a slurry. The methods may also include depositing the slurry on a substrate.

Abstract: An electrode cell manufacturing process may include forming an electrode sheet including an electrode material and an active material. A first plurality of electrode tab windows may be defined in the active material to expose first portions of the electrode material. The process may also include slitting the electrode sheet along a first line that orthogonally intersects the first plurality of electrode tab windows to define a first electrode strip including a first set of electrodes and a second electrode strip including a second set of electrodes.

Abstract: An electrochemical cell has a cathode having a cathode current collector and a cathode active material, an anode having an anode current collector and an anode active material comprising lithium metal, a liquid electrolyte, a separator between the cathode active material and the anode active material, and a polymer electrolyte lamination layer bonding the anode to the separator. The polymer electrolyte lamination layer is formulated using a crosslinked polymer, a lithium salt, a plasticizer, and an anode additive.

Abstract: Energy storage devices, battery cells, and batteries may include a battery cell component that is formed by a method that includes forming a slurry that includes a ceramic material, a binder, and an ionic dispersant. The ceramic material may be greater than 50% of the slurry by weight. The method may also include applying the slurry to a polymeric material to form a two-layer separator. The slurry may be applied to a thickness of less than or about 10 μm.

Abstract: An electrochemical cell has a cathode having a cathode current collector and a cathode active material, an anode having an anode current collector, lithium metal seed, and an anode cap on the lithium metal seed, a liquid electrolyte, a separator between the cathode active material and the anode active material, and a polymer electrolyte lamination layer bonding the anode to the separator. The polymer electrolyte lamination layer is formulated using a crosslinked polymer, a lithium salt, a plasticizer, and an anode additive. The anode cap and the polymer electrolyte lamination layer work together to produce densely plated lithium metal between the lithium metal seed and the anode cap with little or no external pressure.
