1. Background Polystyrene microspheres (PS microspheres) represent a significant research focus in polymer science due to their unique physicochemical properties, which make them highly suitable for a variety of applications in biochemistry, sensing, catalysis, and more. These microspheres are synthesized…

Abstract Li-rich Mn-based cathodes deliver exceptional specific capacity because they combine cationic and anionic (lattice oxygen) redox activity. However, lattice-oxygen participation at high voltages generates unstable electronic holes and reactive O²⁻ species that ultimately form O–O dimers and release O₂ —…

Abstract We report a rapid, scalable…
On December 24th, CATL officially launched the CATL Bedrock Chassis, the world’s first ultra-safe skateboard chassis. With its outstanding performance of withstanding 120 km/h frontal impact without catching fire or exploding, CATL’s Bedrock Chassis sets a new standard for intelligent chassis safety,…
1. Abstract Electrolyte wetting is a critical process for lithium-ion cell performance: it controls ionic access to active material, influences rate capability and cycling, and affects initial manufacturing yield. This study uses a capillary-based electrolyte wetting test System (EWS1100) to…
Abstract BYD Blade Battery 2.0 is the second-generation lithium iron phosphate (LFP) cell from BYD, released in March 2026 and entering widespread adoption in 2026 model-year vehicles including the refreshed BYD Dolphin and Sealion 06. Compared with the first-generation blade…
Abstract The Galvanostatic Intermittent Titration Technique (GITT) test is an electrochemical method that determines the lithium-ion diffusion coefficient ($D_{Li^{+}}$) of a battery electrode material by applying a short constant current pulse followed by a rest period and analyzing the resulting…
Abstract External pressure exerts a non-linear effect on battery cycle life in silicon-carbon anode cells: moderate compression reduces capacity fading by improving interfacial contact, while excessive pressure accelerates degradation by restricting Li+ transport pathways. In-situ swelling analysis using the IEST SWE2110 on LCO/silicon-carbon pouch cells across six pressure…
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 making slurries, and monitoring their slurry gas production. Lithium-ion battery anode and…
