    Abstract: Energy storage devices, battery cells, and batteries may include a cathode including a cathode current collector having a cathode active material disposed thereon. The devices may include an anode including an anode current collector having an anode active material disposed thereon. The devices may also include a separator positioned between the cathode active material and the anode active material. The separator may include a polymeric base, an intermediate layer, and an adhesive layer.

    Abstract: Cell stacks are presented that include binders for wet and dry lamination processes. The cell stacks, when laminated, produce battery cells (or portions thereof). The cell stacks include a cathode having a cathode active material disposed on a cathode current collector. The cell stacks also include an anode having an anode active material disposed on an anode current collector. The anode is oriented towards the cathode such that the anode active material faces the cathode active material. A separator is disposed between the cathode active material and the anode active material and comprising a binder comprising a PVdF-HFP copolymer. In certain instances, an electrolyte fluid is in contact with the separator. Methods of laminating the cell stacks are also presented.

    Abstract: Energy storage devices, battery cells, and batteries may include a battery cell component produced by methods including depositing a first separator layer over an electrode material, where the first separator layer includes a ceramic material. The methods may include depositing a second separator layer over the first separator layer, where the second separator layer includes an adhesive material. The methods may also include drying the second separator layer to form the battery cell component.
