Abstract Carbon-coated aluminum foil (CCAF) is an aluminum current collector with a thin conductive carbon layer—approximately 2 µm per side—applied to both surfaces to reduce interfacial resistance between the foil and the active material coating. Compared to bare aluminum foil, CCAF…
Abstract Battery slurry resistivity is the electrical resistance per unit geometry of the electrode slurry — the inverse of anode slurry conductivity — and provides a direct, formulation-sensitive indicator of conductive carbon particle dispersion, concentration uniformity, and settling behavior. It…
Abstract Battery slurry viscosity and slurry dispersion state are closely linked, but a 2019 study by Kentaro Kuratani and colleagues (Journal of the Electrochemical Society) found that maximizing slurry dispersion does not guarantee maximum battery rate capacity. Correlating slurry viscosity rheology, electrode CT…
1. Preface A lithium-ion battery electrode slurry is a critical solid-liquid mixture consisting of active material, conductive additive, and binder dispersed in a solvent. Achieving an optimal battery slurry formulation and slurry resistivity is not trivial; it requires meeting specific criteria:…
Abstract CVD silicon-carbon anode (chemical vapor deposition Si-C anode, also called gas-phase or vapor-deposition silicon-carbon) deposits nano-silicon into a porous carbon scaffold via silane decomposition at elevated temperature — the most commercially promising approach to high-capacity silicon-based anodes because it achieves…
1. Article Abstract Nickel-rich layered oxides are among the promising materials for the next generation of high-energy-density lithium-ion batteries. Although increasing nickel content can enhance the battery’s specific capacity, it also increases the sensitivity of the cathode to environmental degradation…
1. Abstract Particle-level mechanical properties control how electrode powders densify and how the electrode microstructure evolves during rolling and calendering. This study links single-particle compressive strength to bulk powder compaction behavior and irreversible deformation for representative cathode and anode materials.…
