Abstract A current collector in a battery is the metallic foil—copper for the anode, aluminum for the cathode—that conducts electrons between the active material coating and the external…
1. Preface In this paper, we explore the correlation between electrolyte wettability and electrode tortuosity by testing the tortuosity and wetting rate of electrodes with different compaction densities…
Abstract Electrolyte wetting in lithium-ion batteries refers to the ability of the liquid electrolyte to fully penetrate the pores of electrode coatings and separators, forming continuous solid–liquid interfaces…
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…
