1. What Is Electrode Characterization and Why Does It Matter? Electrode characterization in lithium-ion batteries refers to the systematic, quantitative evaluation of an electrode sheet’s electrical conductivity distribution,…
Abstract Double-layer (dual-layer) coating is a graphite anode manufacturing technique in which a top layer of small-particle, rate-capable graphite (near the separator) and a bottom layer of large-particle,…
1. Introduction As the new energy market expands and application scenarios diversify, sodium‑ion batteries have attracted considerable attention due to the abundant sodium resources and low material cost.…
Abstract Direct Current Resistance (DCR), also referred to as DCIR (Direct Current Internal Resistance), is a core metric that quantifies a lithium-ion battery’s total internal resistance under DC load,…
Abstract A PAA binder (poly(acrylic acid)) outperforms conventional CMC/SBR binder in silicon-carbon (Si/C) anode electrodes on two measurable, electrode-level properties: electrical conductivity and compression behavior. This study uses…
Abstract Electrode sheet resistance is a critical parameter that determines a cell’s internal resistance, rate capability, and performance uniformity — and in large-scale manufacturing, ambient humidity is a key…
1. Abstract This article presents a faster, more efficient method for screening low temperature electrolyte candidates. By measuring the separator ionic conductivity with different electrolytes across a temperature…
1. Introduction: The Critical Role of Electrode Coating Uniformity Electrode foil surfaces — commonly referred to as the A-side (first coating) and B-side (second coating) — can differ…
Abstract LFP batteries subjected to combined high-temperature and deep-overdischarge stress exhibit an aging mechanism with three distinct stages — activation, linear decay, and accelerated decay — and the DCIR (DC internal resistance) growth…
1. Introduction In lithium-ion battery production, controlling electrode moisture is critical, typically managed through parameters like temperature and time during drying to minimize its impact on performance. However,…
1. Background As one of the most important electrochemical energy storage devices today, the performance enhancement of lithium-ion batteries has always attracted significant attention. Traditional research often focuses…
Abstract Electrode tortuosity quantifies the geometric complexity of ion transport pathways within a battery electrode’s pore network—defined as the ratio of the actual lithium-ion migration distance through the pores…
