Abstract Higher power output and better low-temperature performance in sodium-ion batteries depend heavily on porous electrode microstructure, not on active material chemistry alone. Sodium ions have a smaller…
Abstract High energy density and low expansion in anode-free lithium metal battery (AF-LMB) do not have to be mutually exclusive. A study from the Institute of Physics, Chinese…
Abstract Electrode brittleness testing evaluates the mechanical deformation tolerance of lithium-ion battery current collectors and composite coatings under cyclic bending strain, serving as the critical predictor for electrode…
Abstract Conductive additives are essential components in lithium-ion battery electrodes, typically added at 1–3 wt% to establish electronic conduction networks. The selection and dispersion quality of conductive additives…
Abstract Power battery vs. energy storage battery testing differs fundamentally in test objectives, charge/discharge protocols, temperature profiles, and cycle life requirements. Power batteries (EVs) are tested primarily for…
Abstract Lithium battery failure analysis is a systematic, multi-scale diagnostic process that identifies the root causes of performance degradation — including capacity fade, impedance rise, and safety events…
Abstract Separator ionic conductivity — a quantitative metric (mS cm⁻¹) describing lithium-ion transport through the electrolyte-filled separator — directly governs a cell’s internal impedance, rate capability, and long-term…
Abstract Sodium-ion battery testing requires a multi-level characterization approach covering four hierarchical scales — particle, powder, electrode, and cell — because sodium-ion battery performance limitations originate at each…
Abstract Longitudinal binder migration during the drying process creates compositional stratification that directly impacts the electrochemical performance, adhesion strength, and cycle life of lithium-ion batteries. Traditional manual scraping…
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.…
