Abstract Solid polymer electrolyte refers to a solvent‑free or low‑solvent polymeric membrane that conducts lithium ions through segmental motion of polymer chains and typically requires a lithium salt…
Abstract In 2025, Prof. Dongliang Peng and Prof. Qingshui Xie’s team at Xiamen University, in collaboration with Prof. Jun Lu’s team at Zhejiang University and Argonne National Laboratory,…
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…
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. Introduction Gas generation is an unavoidable phenomenon during the battery manufacturing process and its usage, occurring in various stages such as formation, cycling, overcharging, over-discharging, and storage.…
In this paper, an IEST in-situ volume monitor (GVM) is used to carry out in-situ overcharge volume test under different charging rate conditions (0.5C) on lithium cobalt oxide/graphite…
