Abstract: A prismatic battery cell and a method of making such a cell. The cell includes one or more anode regions, cathode regions, and electrolyte regions to facilitate ion flow between the anode and cathode regions. Electrically-conductive tabs are attached to the corresponding anode and cathode regions, and a pouch-like containment is formed around the regions. The containment includes facing substantially planar surfaces sealingly joined to one another. A barrier layer coating includes at least one low-permeability material and is placed over at least a portion of the cell edge defined by the joined surfaces such that the barrier layer coating blocks ambient gases or vapors from passing through the heat seal region that is used to join the pouch surfaces. The barrier layer coating may also include one or more hydrophobic surface treatments or enhancements, including an additional layer of surface treatments or, in another form, by surface roughening.

Abstract: A photocatalytic system having enhanced photo efficiency/photonic efficacy is provided that includes a thin nucleation material coated on a substrate. The nucleation material enhances lattice matching for a subsequently deposited photocatalytic active material. Such a photocatalytic system may be used as a self-cleaning surface in an application where removal of fingerprints and other residue is desired. In certain aspects, the nucleation material comprises aluminum oxide (Al2O3) and the photocatalytic material comprises an anatase phase of titanium dioxide (TiO2) deposited over the nucleation material. A photocatalytic activity of the system is ≥about 50% above a comparative photocatalytic activity where the photocatalytic active material is disposed directly on the substrate. Methods of making such photocatalytic systems are also provided.

Abstract: A prismatic battery cell and a method of making such a cell. The cell includes one or more anode regions, one or more cathode regions, an electrolyte region to facilitate ion flow between the anode and cathode regions, electrically-conductive tabs attached to the corresponding anode and cathode regions, and a pouch-like containment formed around the regions. The containment is made up of a pair of facing substantially planar surfaces sealingly joined to one another. A barrier layer coating is made up of at least one low-permeability material and is placed over at least a portion of the cell edge that is defined by the joined surfaces such that the barrier layer coating blocks ambient gases or vapors from passing through the relatively gas-permeable heat seal region that is used to join the pouch surfaces. The barrier layer coating may also include one or more hydrophobic surface treatments or enhancements, including in one form an additional layer of surface treatments to funtionalize the surface and in another form by surface roughening.
