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,…
Abstract Sodium-ion battery testing requires characterization at four levels: particle, powder, electrode, and cell. Limitations introduced at each level can ultimately affect cell performance and reliability. At the…
1. Introduction A research team from CATL’s 21C Innovation Lab has achieved a significant breakthrough in lithium metal battery technology, with their independent study “Application-driven design of non-aqueous…
Abstract Pure silicon anodes reach a silicon anode volume expansion percentage of approximately 280% during full lithiation — roughly 28 times greater than graphite’s ~10% — making silicon…
1. Preface This paper focuses on quantifying the extent of pressure damage to the material by using different pressures to flat-press silicon-based anode materials powders after calendering and…
1. Preface Among the many cathode materials, the high nickel material LiNixM1-xO2 (M = Mn, Co, Al, etc.) exhibits high energy density as well as good cycle life.…
Abstract This study uses synchronized in-situ measurement to quantify Thickness Swelling and volume swelling of LiFePO₄ (LFP)/graphite pouch cells during charge–discharge. Because LFP (olivine) shows minimal structural expansion,…
Abstract In-situ battery gas analysis is a measurement approach that tracks the composition and volume of gases generated inside a lithium-ion cell in real time, without disassembling the…
1. Introduction With the rapid development of the lithium-ion battery industry, silicon-based anode materials have gained attention due to their high theoretical specific capacity. Silicon-based slurry typically use…
IEST introduce a variety of special characterization instruments for the lithium battery industry (powder resistance meter, slurry resistance meter, electrode resistance meter, cell in-situ swelling and gas production…
Literature Appreciation: Entropy Surface Engineering Promotes The Stability Of Multi-electron Reactions Of Anions And Cations In Li-rich Layered Cathodes First Author: Jiayu Zhao Corresponding Authors: Yuefeng Su, Jinyang…
1. Author Information and Article Abstract In 2017, the J.R.Dahn research group used the in-situ characterization method to test the volume, stress and thickness changes of the electrodes…
