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,…
1. Preface This paper proposes a more appropriate test parameter based on the specific test data of the electrode resistance, so as to ensure the accuracy and stability…
Abstract The core difference between the two-probe and four-probe method for battery electrode resistance testing is what each method actually measures. The 2 point probe (two-point probe) method…
Abstract Battery electrolyte viscosity—the resistance of a liquid electrolyte to flow—is the primary physical parameter controlling capillary wettability of electrode sheets during lithium-ion cell manufacturing. Lower electrolyte viscosity…
1. Abstract Accurate measurement of separator ion conductivity is essential for predicting cell rate capability, internal resistance, and overall safety. This application note describes a high-throughput, multi-channel workflow…
1. Preface The multiplier performance of the battery affects the speed and life of the battery charge and discharge. How to reduce the battery resistance and improve the…
