Abstract Power battery vs. energy storage battery testing differs fundamentally in test objectives, charge/discharge protocols, temperature profiles, and cycle life requirements. Power batteries (EVs) are tested primarily for rate capability, fast-charge performance, and low-temperature discharge under constant current conditions per…
Abstract Lithium battery failure analysis is a systematic, multi-scale diagnostic process that identifies the root causes of performance degradation — including capacity fade, impedance rise, and safety events — by decomposing cell behavior into distinct mechanical, electrochemical, and structural failure…
Abstract B/Zr co-doping is a lattice-bulk regulation strategy for stabilizing ultra-high-nickel single-crystal cathodes by coordinating bulk lattice reinforcement with surface structural protection. Reported by Wei Shu, Zhou-Shuang Fan, An-Qiang Pan, Yun Liu, Wen-Xing Zhang and co-authors in Advanced Powder Materials…
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 by Academician Sun Xueliang and Professor Wang Changhong at Ningbo Eastern University…
Abstract A research team from Central South University (Prof. Fan Xinming) and Xiamen University (Prof. Yang Yong) has published a landmark study in Advanced Materials (DOI: 10.1002) that fundamentally redefines the high-voltage cycling failure mechanism of single-crystal Ni-rich cathodes. Using…
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 B/Zr co-doping is a lattice-bulk regulation strategy for stabilizing ultra-high-nickel single-crystal cathodes by coordinating bulk lattice reinforcement with surface structural protection. The Advanced Powder Materials study investigates single-crystalline $LiNi_{0.92}Co_{0.04}Mn_{0.04}O_2$ (SNCM) and develops SCNCM@0.5%Zr/B to address the coupled problems of Ni-rich cathode internal…
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…
