Abstract: A method for manufacturing an interfacial lithium fluoride layer for an electrochemical cell that cycles lithium ions is disclosed. In the method, a substrate is positioned in a reaction chamber of an atomic layer deposition reactor and a lithium fluoride (LiF) precursor is introduced into the reaction chamber such that the LiF precursor contacts and chemically reacts with functional groups on the substrate. Then, an oxidant is introduced into the reaction chamber to form a single molecular layer of lithium fluoride on the substrate. The lithium fluoride layer is formed on the substrate at a temperature of greater than or equal to about 110 degrees Celsius to less than or equal to about 250 degrees Celsius.

Abstract: A quality control system in a battery manufacturing process includes two or more capacitive measurement apparatuses to obtain a capacitance measurement from two or more intermediate products generated during the battery manufacturing process. The system also includes processing circuitry to obtain the capacitive measurement from the two or more capacitive measurement apparatuses, to determine a characteristic of the corresponding intermediate product, and to control at least one process of the battery manufacturing process that produced at least one of the two or more intermediate products based on the characteristic.

Abstract: A composite panel for a vehicle includes a plurality of layers bonded together by resin. A sensing assembly is arranged between at least two of the plurality of layers. The sensing assembly includes at least one of a piezoelectric layer to sense vibration of the composite panel when installed on the vehicle and a thermopile configured to sense changes in temperature of the composite panel when installed on the vehicle. The sensing assembly further includes a transmitter configured to transmit data to the vehicle based on an output of the at least one of the piezoelectric layer and the thermopile.
