IMLB 2024 is the premier international conference on the state of lithium battery science and technology, as well as current and future applications in transportation, commercial, aerospace, biomedical, and other promising sectors. The conference will be held from June 17-21,…
Research Topics：Characterization and Quantification of Multi-field Coupling in Lithium-ion Batteries Under Mechanical Constraints First Author: Xue Cai Corresponding Authors: Caiping Zhang, Weihan Li Affiliated Institutions: Beijing Jiaotong University, RWTH Aachen University Equipment Used: IEST SWE2110 (1T Room Temperature Expansion Testing…
1. Abstract Dry electrode technology is emerging as a key enabler for next-generation battery formats — including large-format cylindrical cells, semi-solid/solid-state cells, and high-capacity designs — because it eliminates solvent use, reduces capital and energy costs, and enables thicker, crack-free…
In April 2024, IEST Product Manager Yi Wang and Overseas Sales Engineer Edward embarked on a one-month customer follow-up trip to the United States. The purpose of this visit was to gain in-depth insights into customers’ experiences and needs when…

At the 2024 China Auto Show, CATL released the world’s first 4C ultra-fast charging CATL lifepo4 battery with a range of more than 1,000 kilometers – Shenxing PLUS. Within 8 months since the launch of the Shenxing ultra-fast charging battery in…
Abstract Battery electrolyte viscosity—the resistance of a liquid electrolyte to flow—is the primary physical parameter controlling capillary wettability of electrode sheets during lithium-ion cell manufacturing. Lower electrolyte viscosity accelerates infiltration of the electrode pore network, reducing dry spots and improving…
Abstract Cell swelling refers to the thickness expansion and internal force generation that a lithium battery cell exhibits during charge-discharge cycling, arising from electrode structural changes and gas generation from electrolyte decomposition. A battery cell swelling test quantifies this behavior using one of…
Abstract A model coin cell is a test-format battery cell designed to closely reproduce the coin cell voltage curve, coulombic efficiency, and thickness expansion behavior of finished cells, while allowing much faster assembly and screening than a full pouch or cylindrical…
Abstract Silicon-based anodes face five principal barriers to commercialization: volume expansion reaching 300% during full lithiation, gas evolution during slurry processing, electrical conductivity approximately 108 times lower than carbon, initial Coulombic efficiency (ICE) as low as 70–90%, and the need…
