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, a research team led by Prof. Dongliang Peng and Prof. Qingshui Xie at Xiamen University, in collaboration with Prof. Jun Lu’s team at Zhejiang University, and researchers from Argonne National Laboratory, published a study in ACS Nano…
Abstract Li-rich manganese-based layered oxide cathodes (LRMs) are promising candidates for next-generation high-energy-density lithium-ion batteries because of their high specific capacity and low cost. But their practical application is limited by irreversible oxygen release, transition-metal migration and phase transformation, voltage…
Abstract The assembly and operation of sulfide solid-state batteries (ASSLBs) involve three pressure stages with distinct functions. Yan et al. (JCIS 2026) demonstrated that treating pressure as a single parameter can obscure its stage-specific effects on interfacial structure and electrochemical…
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) 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…
Abstract Battery self-discharge is the spontaneous capacity and voltage loss of a lithium-ion battery under open-circuit conditions — a critical performance parameter for cell quality, consistency screening, and long-term storage reliability. The three conventional self-discharge measurement methods — direct capacity loss measurement, open-circuit…
