Abstract: A method of manufacturing an electrode for an electrochemical cell includes providing an admixture including an electroactive material, a binder, and a solvent. The method further includes rolling the admixture to form a sheet and forming a multi-layer stack from the sheet. The method further includes forming an electrode film precursor by performing a plurality of sequential rollings, each including rolling the stack through a first gap. The plurality of sequential rollings includes first and second rollings. In the first rolling, the stack is in a first orientation. In the second rolling, the stack is in a second orientation different from the first orientation. The method further includes forming an electrode film by rolling the electrode film precursor through a second gap less than or equal to the first gap. The method further includes drying the electrode film to remove at least a portion of the solvent.

Abstract: A data analytics system for a vehicle includes one or more controllers having a multi-layered control software architecture including two or more software layers and a health monitoring structure. The one or more controllers execute instructions to receive a fault, and in response to receiving the fault, generate, by the health monitoring structure, a plurality of unique triggers as the fault propagates throughout the multi-layered control software architecture. The controllers build a network including a plurality of propagation paths and identify one or more main propagation paths that are part of the network based on a data analysis of a mock big data set. The one or more controllers build a complete propagation pathway including two or more main propagation paths. In response to determining only one main propagation path, the controllers determine a root cause of the fault based on the only one main propagation path.
