摘要： A standalone lithium ion-conductive sulfide solid electrolyte, methods of making and using the electrolyte, and battery cells and cell components incorporating the electrolyte can include a freestanding inorganic vitreous sheet of sulfide-based lithium ion conducting glass capable of high performance in a lithium metal battery by providing a high degree of lithium-ion conductivity while being highly resistant to the initiation and/or propagation of lithium dendrites. Such an electrolyte is also itself manufacturable, and readily adaptable for battery cell and cell component manufacture, in a cost-effective, scalable manner.

摘要： Systems and methods are provided for high volume roll-to-roll direct coating of electrodes for silicon-dominant anode cells. A slurry that includes silicon particles and a binder material may be applied to a current collector film, and the slurry may be processed to form a precursor composite film coated on the current collector film. The current collector film with the coated precursor composite film may be rolled into a precursor composite roll. A heat treatment may be applied to the current collector film with the coated precursor composite film in an environment including nitrogen gas, to convert the coated precursor composite film to a pyrolyzed composite film coated on the current collector film. The heat treatment may include applying the heat treatment to the precursor composite roll in whole and/or applying the heat treatment to the current collector film with the coated precursor composite film as it is continuously fed.
