Abstract The effect of SOC on NCM cathode particle crushing strength is both dramatic and nonlinear: as the state of charge increases from 0% to 100%, the single-particle crushing strength of polycrystalline NCM cathode material drops from ~40 MPa to…
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 cycle stability. This study validates the separator ionic conductivity and battery cycle…
Abstract Silicon anodes for all-solid-state batteries must accommodate large volume changes while maintaining stable solid-solid contact and rapid Li-ion transport. Conventional encapsulation can preserve particle integrity but impede interparticle ion transport, whereas uncontrolled electrochemical sintering can restore contact but also…
Abstract A powder compression test is a mechanical characterization method that applies stepwise pressure to an electrode powder bed and records the resulting thickness change to separate reversible (elastic) deformation from irreversible (plastic) deformation. Using the IEST PRCD Powder Resistivity…
Abstract Coherent twin boundaries (CTBs) are periodic crystallographic interfaces introduced into a Li-rich cathode — specifically a Li-rich layered oxide (LRO) — through staged-temperature calcination, and they address the three limiting factors of a thick electrode design: restricted two-dimensional lithium-ion…
Abstract In-situ swelling testing of silicon-carbon pouch cells is an important characterization method in silicon-anode battery development. However, reproducible and engineering-relevant results depend strongly on the mechanical boundary conditions applied during testing and how closely they represent the compliant constraints…
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…
