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…
1. Abstract This article translates and adapts a practical decomposition method that quantifies those contributions by measuring total resistance across samples of varying coating thickness. The method uses…
1. Preface This paper compares the effects of flat-compaction and roller pressing on the compaction density and resistivity of the graphite electrode to provide reference data for battery…
Abstract The dry electrode process — a solvent-free manufacturing route that compresses active material, conductive additive, and PTFE binder directly onto a current collector without NMP coating and…
Abstract Separator layer coating — applying polymeric or ceramic layers onto a microporous polyolefin (PE/PP) support — improves wettability, thermal stability, and mechanical strength, but also changes porosity, tortuosity,…
