Abstract In-situ swelling testing of silicon-carbon pouch cells is a cornerstone measurement in silicon-anode battery development — yet test results are only reproducible and engineering-relevant if the mechanical boundary condition applied during testing matches the compliant constraint of a real battery…
Abstract Solid polymer electrolyte refers to a solvent‑free or low‑solvent polymeric membrane that conducts lithium ions through segmental motion of polymer chains and typically requires a lithium salt and sometimes a plasticizing agent such as a deep eutectic solvent to…
Abstract In 2025, Prof. Dongliang Peng and Prof. Qingshui Xie’s team at Xiamen University, in collaboration with Prof. Jun Lu’s team at Zhejiang University and Argonne National Laboratory, published a study in ACS Nano titled “Modulating Surface Anionic Redox Chemistry toward Highly…
Abstract Li-rich manganese-based layered oxide cathodes (LMNO) are strong candidates for next-generation high-energy-density lithium-ion batteries thanks to their high specific capacity and low cost — but they face compounding failure modes: irreversible oxygen release during the first cycle, transition-metal migration…
Abstract Sulfide solid-state batteries assembly requires three distinct pressure stages, not one. Yan et al. (JCIS 2026) demonstrate that treating “assembly pressure” as a single parameter misses critical interfacial physics. Their optimal three-stage protocol for LPSCl and LGPS electrolytes: Pre-pressing (electrolyte…
Abstract Graphite lithiation—the process by which lithium ions intercalate into graphite anode layers during battery charging—proceeds through multiple ordered stage transitions that directly determine the rate and safety of fast charging. A 2026 JACS study by researchers at Nanjing University…
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) stands as a premier international conference in the lithium battery field, focusing on cutting-edge scientific research, industrial implementation, and both current and forward-looking applications across transportation, commercial, aerospace,…
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 level and propagate upward to cell-level failure. At the particle level, single-particle…
