Abstract Separator ionic conductivity — a quantitative metric (mS cm⁻¹) describing lithium-ion transport through the electrolyte-filled separator — directly governs a cell’s…
Abstract Sodium-ion battery testing requires a multi-level characterization approach covering four hierarchical scales — particle, powder, electrode, and cell — because sodium-ion…
Abstract Longitudinal binder migration during the drying process creates compositional stratification that directly impacts the electrochemical performance, adhesion strength, and…
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…
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 bot…
1. Introduction As the new energy market expands and application scenarios diversify, sodium‑ion batteries have attracted considerable attention due to the abundant sodium resourc…
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 inter…
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: electri…
Abstract Electrode sheet resistance is a critical parameter that determines a cell’s internal resistance, rate capability, and performance uniformity — and in large-scale ma…
1. Abstract This article presents a faster, more efficient method for screening low temperature electrolyte candidates. By measuring the separator ionic conductivity with differen…
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 d…
Abstract LFP batteries subjected to combined high-temperature and deep-overdischarge stress exhibit an aging mechanism with three distinct stages — activation, linear decay, and a…
