Abstract Electrode tortuosity (\(\tau\)) is a dimensionless microstructural parameter quantifying how much the actual ionic transport path through a porous battery electrode deviates from a straight line; the…
Abstract Nano-Carbon coated aluminum foil is an aluminum current collector with a thin conductive carbon layer—applied to both surfaces to reduce interfacial resistance between the foil and the…
1. Introduction: Calendering Compaction as a Key Lever for Electrode Resistance Electrode resistance is a key indicator of electronic conductivity within the coating, closely linked to parameters such…
Abstract The two probe method and four probe method differ primarily in how they handle contact resistance—the impedance at the junction between a measurement probe and the sample…
Literature appreciation: Influence of High Intensive Dry Mixing and Calendaring on Relative Electrode Resistivity Determined Via An Advanced Two Point Approach 1. Author Information and Article Abstract Bastian…
1. Preface The method used in this article is a further improvement on the two-probe method. It adopts a four-wire method plus a controllable pressure double-disc electrode to…
1. Abstract Electrode resistance is a sensitive, process-coupled metric that reflects slurry formulation, conductive-additive loading and calendering/compaction conditions. This study uses a controlled four-probe, pressure-applied measurement workflow (BER1300)…
1. Preface Lithium-ion (Li-ion) batteries have become one of the main energy storage solutions for the consumer, power and energy storage markets due to their long cycle life…
Abstract The MacMullin number (also spelled McMullin number; symbol \(N_m\), defined as \(N_m = \tau/\varepsilon = \sigma/\sigma_{eff}\)) quantifies effective ionic transport resistance inside porous battery electrodes — the…
1. Preface Copper and aluminum foils serve as essential current collectors in lithium-ion battery electrodes, conducting electrons and supporting the active material layer. Their chemical and electrochemical stability significantly impacts…
1. Abstract Electrolyte filling is a critical step in lithium-ion cell manufacturing. Poor wetting increases internal resistance, reduces capacity, and can create localized current hotspots that promote…
Abstract Calendering pressure is the primary process lever for controlling graphite anode electrode compaction density and through-thickness electrical resistivity in lithium-ion battery manufacturing. In this study, four graphite…
