1. Background Understanding the mechanical behavior of individual material particles is crucial for advancing lithium-ion battery technology. The Single Particles Force properties Tester (SPFT) from IEST is specifically designed to characterize the mechanical properties of single cathode and anode particles,…
Abstract NCM cathode material (also written NMC — the two abbreviations refer to the same material family, see Section 1.1) is a layered oxide cathode with the general formula LiNixCoyMnzO₂ (x + y + z = 1), where nickel content controls energy density…
Abstract The core difference between the two-probe and four-probe method for battery electrode resistance testing is what each method actually measures. The 2 point probe (two-point probe) method measures total through-plane resistance — the composite of contact resistance, coating layer…
Abstract Yes, you can charge a BYD Blade Battery to 100% regularly without harming it — this is a key benefit of its Lithium Iron Phosphate (LFP) chemistry. For daily use, keeping the charge between 20%–80% State of Charge (SOC)…
Abstract Argyrodite-type sulfide solid electrolytes (Li7−xPS6−xClx, LPSCl) deliver room-temperature ionic conductivity exceeding 1 mS/cm—among the highest of any inorganic solid electrolyte—but react rapidly with trace moisture, generating H₂S and forming low-conductivity surface phases. This study by Morino et al. (J. Phys.…
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…
