Abstract Solid electrolyte electronic conductivity — long assumed negligible in all-solid-state battery (ASSB) design — is now revealed as a hidden driver of physical self-discharge. A team led…
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…
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 —…
Journal: Energy Materials Organization: School of Materials, Xiamen University, IEST Instrument. Authors: Jie Zhu, Yunfan Wu, Hongyi Zhang, Xujia Xie, Yong Yang, Hongyu Peng, Xiaochun Liang, Qiongqiong Qi,…
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…
Abstract ASSB (All-Solid-State Battery) is an electrochemical energy storage device in which both electrodes and the electrolyte are solid-phase materials, eliminating the flammable liquid electrolyte used in conventional lithium-ion…
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 Argyrodite-type sulfide solid electrolytes (Li7−xPS6−xClx, LPSCl) deliver room-temperature ionic conductivity exceeding 1 mS/cm—among the highest of any inorganic solid electrolyte—but react rapidly with trace moisture, generating H₂S and…
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…
