Europe Bets on Fuel Cells to Challenge Battery Dominance

The mobility battery sector is currently dominated by Asian companies, particularly from South Korea, China, and Japan, thanks to their technological prowess and robust supply chains. Recent data shows CATL from China holding a 37.9% market share in 2024, with BYD at 17.2%, highlighting their lead (Global EV battery market share: CATL leads with 37.9%). Meanwhile, Europe faces challenges, as seen with Northvolt’s bankruptcy filing in Sweden on March 12, 2025, attributed to high labor costs and difficulty competing with Asian manufacturers.

Thermal Wrinkling: A Hidden Challenge in EV Battery Anode Production and Its Solutions

Thermal Wrinkling: A Hidden Challenge in EV Battery Anode Production and Its Solutions Battery anodes for electric vehicles (EVs) are typically mass-produced using the Roll-to-Roll (R2R) process. However, an unexpected and significant hurdle in this continuous manufacturing method is “thermal wrinkling.” Thermal wrinkling refers to the permanent folds that occur in electrode sheets due to thermal-induced deformation, which does not revert upon cooling. Recent research has highlighted this issue, analyzing its root causes and proposing effective mitigation strategies. When Does Thermal Wrinkling Occur? Thermal wrinkling primarily occurs in drying ovens when electrode sheets experience rapid or uneven heating. Differential thermal expansion between the copper current collector foil and the coating layer destabilizes web tension, causing irreversible wrinkling and plastic deformation. Specifically, during the drying stage of the R2R process, high and inconsistent oven temperatures cause uneven thermal expansion rates between layers. This differential expansion generates uneven mechanical stresses across the electrode web, leading to wrinkles forming primarily in the transverse direction. Factors such as inadequate tension control, roller misalignment, non-uniform coating thickness, or abrupt temperature changes exacerbate the severity of thermal wrinkling, emphasizing the need for precisely controlled manufacturing conditions. Impact of Thermal Wrinkling Wrinkled electrodes exhibit compromised flatness and

Next-Generation Materials Laboratory: Innovations in Alloys, Amorphous Materials, and Composites

Next-Generation Materials Laboratory : Innovations in Alloys, Amorphous Materials, and Composites In the near future, materials laboratory is expected to feature robotic arms meticulously assembling samples, while AI systems simultaneously analyze data in real-time. Such a scene is not merely science fiction; it represents the forthcoming reality of next-generation labs that will revolutionize the way materials—from advanced alloys to sophisticated composite materials—are produced. Approximately a decade ago, the U.S. Materials Genome Initiative challenged scientists to discover and manufacture novel materials twice as fast and at a fraction of the traditional costs. Achieving these ambitious goals has become even more urgent due to climate change, geopolitical tensions, and unstable supply chains. To realize such accelerated innovations, a paradigm shift in materials laboratory workflow is essential. Future labs will replace slow, isolated experiments with fully integrated, automated pipelines that seamlessly combine design, synthesis, processing, and characterization. Utilizing next-generation experimental tools, automation, AI and machine learning integration, and multimodal characterization, these labs aim to quickly bridge the gap from material invention to practical production technologies. These advancements address critical bottlenecks in the manufacturing of metal alloys, amorphous materials (such as glasses), and composites, significantly impacting future manufacturing strategies.

The Importance of Bulk Properties in High Quality Chemical Materials Manufacturing

The Crucial Role of Bulk Properties in Scaling Chemical Materials for Efficient Mass Production. When developing chemical materials, research and development teams often begin at a small scale. In the early stages, the focus is primarily on the fundamental properties of the material itself, including its molecular structure, its surface area, the nature of its chemical bonding, its morphology, and its intrinsic reactivity. These characteristics are crucial for determining the eventual performance of the material in its intended application, whether that application is as a catalyst, a polymer additive, a coating material, a battery electrode component, or any other specialized function. The initial development phase involves in-depth analysis using advanced characterization and simulation techniques to thoroughly understand the material’s fundamental properties. This crucial step provides the foundational knowledge necessary for optimizing its performance and ensuring consistent quality during large-scale manufacturing. However, a significant challenge arises when moving from small-scale laboratory development to larger-scale manufacturing. The material that performed exceptionally under controlled, small-batch conditions may not behave the same way in bulk. In fact, certain properties that were previously negligible or easily managed at the laboratory level can become critically important when the material is synthesized, processed, and handled in ton-scale
