Application: Sintered electrodes for batteries and method of preparing same (Patent ID: US20230395798A1)
The patent filed by Corning Inc. describes methods of making sintered electrodes using a slurry containing specific weight percentages of chalcogenide powder, binder, and solvent. The process involves casting the slurry into a green tape, drying it to remove solvent, and sintering it at a specific temperature range to form the electrode. The resulting electrode can be used in batteries, maintaining a high charging capacity after multiple cycles.
The claims detail specific aspects of the method, such as the composition of the powder, the type of solvent used, the materials the electrode can be made of, and the characteristics of the sintered electrode. The method aims to produce electrodes with specific properties, such as thickness, porosity, grain size, and charging capacity, suitable for use in batteries. Additionally, the method includes steps for assembling a battery using the sintered electrode as a cathode, highlighting the practical application of the patented process in battery manufacturing.
