Abstract: A battery component is described that has at least one ceramic layer that includes ceramic particles and a binder. The ceramic particles may include α-alumina or γ-alumina. The ceramic layer may be characterized by a porosity of greater than or about 40 vol %. In additional embodiments, the one or more ceramic layers may have a weight ratio of ceramic particles to binder is greater than or about 90:10. The battery component may be a battery separator that is characterized by a MacMullin number of less than or about 40 and a thermal shrinkage of less than or about 1 vol. % after 1 hour at 140° C.

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 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.
