Abstract Battery internal resistance, resistance, and impedance are three related but distinct electrical parameters used to characterize lithium-ion battery materials and cells. Resistance (R) describes the general opposition…
Abstract Solid electrolyte electronic conductivity has received far less attention than ionic conductivity, but even a small electronic leakage current can cause physical self-discharge in all-solid-state batteries (ASSBs).…
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…
Abstract A sSilicon-based anode all-solid-state battery (ASSB) operating without external pressure has been demonstrated for the first time at a practical scale, achieving 1,000 stable cycles at 2.5…
Abstract LLZO (Li₇La₃Zr₂O₁₂) solid electrolyte is a garnet-type oxide solid-state electrolyte that offers electrochemical stability against lithium metal and high lithium-ion conductivity — making it a leading candidate…
1. Abstract Oxide solid electrolytes are a leading candidate for high-energy, high-safety next-generation batteries. This article presents IEST’s practical solutions for rapid, reliable oxide solid electrolyte characterization —…

1. Preface In this paper, IEST has tested the expansion behavior of sulfide solid-state battery during charging and discharging by using a Solid Electrolyte Test System(SEMS) and a In-Situ…
Abstract All-solid-state batteries (ASSBs) promise higher intrinsic safety and the potential for much higher energy density by replacing flammable liquid electrolytes with solid ionic conductors. However, numerous materials…
The following are recent developments and innovative approaches in the field of solid-state battery, with some findings excerpted from reports by universities and research institutions. 1. Negative electrode-free…
Abstract Activation energy (\(E_a\)) in battery materials is the minimum energy barrier that charge carriers — lithium ions or electrons — must overcome to migrate through a material,…
Abstract Solid-state electrolyte testing is the systematic evaluation of a solid electrolyte’s ionic conductivity, electronic conductivity, compaction density, and electrochemical stability under controlled mechanical pressure. Electrolyte measurement in this context requires…
