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 and …
Abstract The MacMullin number (also spelled McMullin number; symbol \(N_m\), defined as \(N_m = \tau/\varepsilon = \sigma/\sigma_{eff}\)) quantifies effective ionic transport resi…
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 …
1. Abstract Electrolyte filling is a critical step in lithium-ion cell manufacturing. Poor wetting increases internal resistance, reduces capacity, and can create localized…
Abstract Calendering pressure is the primary process lever for controlling graphite anode electrode compaction density and through-thickness electrical resistivity in lithium-ion …
1. Abstract This article translates and adapts a practical decomposition method that quantifies those contributions by measuring total resistance across samples of varying coating…
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…
1. Abstract Dry electrode technology is emerging as a key enabler for next-generation battery formats — including large-format cylindrical cells, semi-solid/solid-state cells, and…
1. Abstract Separator performance directly shapes lithium-ion battery behaviour. In addition to electrical insulation, a separator must enable rapid Li⁺ transport, retain electrol…
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 of the tes…
1. Preface This paper presents a 2 probe vs 4 probe comparison for measuring electrode resistance in lithium-ion batteries, focusing on the 2 point probe and 4 point probe methods…
Abstract Battery electrolyte viscosity—the resistance of a liquid electrolyte to flow—is the primary physical parameter controlling capillary wettability of electrode sheets durin…
