Abstract Graphite lithiation, the intercalation of lithium ions into graphite during battery charging, proceeds through multiple ordered staging transitions that strongly influence the rate and safety of fast charging. In a 2026 JACS study, researchers at Nanjing University and CATL’s…
Abstract Powder resistivity measurement systems and powder compaction density testers (collectively referred to as Powder Resistivity and Compaction Density, PRCD systems) characterize the electrical conductivity, compaction behavior, and mechanical deformation of battery active materials under controlled pressure. These measurements serve…
Abstract Anode particle size and crushing strength are inversely correlated: smaller particles consistently achieve higher crushing strength (MPa, resistance per unit area) while larger particles generate higher absolute crushing force (N, total force to fracture). This counter-intuitive relationship holds across…
MONTREAL, CANADA — The 23rd International Meeting on Lithium Batteries (IMLB 2026), held in Montreal from June 14 to 19, 2026, brought together more than 2,000 leading electrochemists, researchers, and industry specialists to discuss cutting-edge fundamental and applied breakthroughs in…
Abstract Sodium-ion battery testing requires characterization at four levels: particle, powder, electrode, and cell. Limitations introduced at each level can ultimately affect cell performance and reliability. At the particle level, single-particle crushing strength differentiates the mechanical response of layered oxide…
Abstract Battery self-discharge is the spontaneous capacity and voltage loss of a lithium-ion battery under open-circuit conditions and is often accompanied by a decrease in open-circuit voltage. It is a critical performance parameter for evaluating cell quality, consistency, and long-term…
Stuttgart, Germany — IEST Instruments showcased its advanced battery testing equipment and laboratory automation solutions at The Battery Show Europe 2026, held from June 9 to 11, 2026, at Messe Stuttgart. The event brought together over 1,160 exhibitors and thousands…
Abstract A recent study published in Nano Materials Science by researchers at Beijing Institute of Technology systematically investigated how external mechanical pressure influences interfacial stability and failure mechanisms in LFP/graphite battery. The researchers compared cells cycled without applied pressure (0…
Abstract Tianjin, March 23, 2026 — The Nanoyang research group at Tianjin University and IEST Instrument (Xiamen) jointly announced the official launch of their Joint Laboratory at a ceremony held on the Tianjin University campus. The event brought together leading experts in China’s new energy materials field, including Academician…
Abstract Battery cell swelling can be caused by lithium-ion intercalation, gas evolution, and temperature changes during charge and discharge. Cell thickness change and foam compression become mechanically coupled when buffer foam is placed between cells or between cells and the…
