Abstract: A cathode for a high voltage lithium-ion secondary battery is described, including: an electrode layer having an electrode composition containing cathode active particles, fluoropolymer binder and conductive carbon. The cathode active particles are high voltage lithium transition metal oxides, the fluoropolymer binder is a fibrillated tetrafluoroethylene polymer having high melt creep viscosity, and the conductive carbon is carbon fibers having a specific surface area of about 50 m2/g or less. The carbon fibers and the fluoropolymer binder form a conducting structural web electronically connecting the cathode active particles, enabling electronic conductivity through the electrode layer. The electrode layer is adhered to a current collector comprising aluminum having surface roughness and substantially no carbon surface coating other than the conductive carbon of the electrode layer. Further described is a dry binder process to fabricate such cathodes, and the utility of such cathodes in high voltage lithium-ion secondary batteries.

Abstract: A lithium metal battery includes an anode that has a lithium metal core material and a passivation layer coated on the lithium metal core material. The passivation layer may be comprised of a plurality of layers. The passivation layer is formed by depositing first material comprised of lithium nitrate and a second material material comprised of one or more of a lithium borate salt, polyvinylidene fluoride (PVDF), and (vinylbenzyl) trimethylammonium chloride (VBTC). The first and second material may react with the lithium metal of the anode, other battery components or between the lithium nitrate and the second material(s).

Abstract: A method for manufacturing zinc negative electrodes includes mixing a powder including zinc with polytetrafluoroethylene to form a homogenous blend, injecting a lubricant into the homogenous blend to form a dough, kneading the dough to form a fibrillated dough, and extruding the fibrillated dough through a die to form a ribbon. The method also includes calendering the ribbon to a target thickness to form a plaque, drying the plaque to form an active material sheet, laminating portions of the active material sheet to a current collector substrate such that the current collector substrate is sandwiched between the portions to form an electrode blank, and sectioning the electrode blank into zinc negative electrodes.
