Abstract Advanced solid-state battery testing requires coordinated characterization of solid-electrolyte transport, electrode–electrolyte interfaces, mechanical behavior, and electrochemical performance under controlled pressure and atmospheric conditions. The essential instruments include…
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 —…
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…
