Kinetics Compensation Mechanism in Cosolvent Electrolyte Strategy for Aqueous Zinc Batteries

Prof. Yunhui Huang’s Group Leads the Way in Battery Innovation: Key Research Highlights (2025)-2

Prof. Yunhui Huang’s Group Leads the Way in Battery Innovation: Key Research Highlights (2025)-2 11. Journal of the American Chemical Society: Kinetics Compensation Mechanism in Cosolvent Electrolyte Strategy for Aqueous Zinc Batteries Professor Yunhui Huang’s team from Huazhong University of Science and Technology has addressed the inevitable kinetic losses associated with the introduction of co-solvents. They proposed a kinetic compensation mechanism designed to weaken cation-anion interactions and increase the Zn2+ transference number, thereby partially offsetting the kinetic degradation caused by co-solvents. Using an Zn(OTf)2 based aqueous electrolyte containing ethylene carbonate (EC) as a model system, the team demonstrated the effectiveness of this strategy in achieving kinetic compensation and enhancing the

How to Ensure the Reliability of Lithium-ion Batteries in Extreme Environments? 2026

Ensuring Lithium-ion Battery Reliability: Safety Mechanisms and Failure Analysis in Extreme Environments With the widespread adoption of lithium-ion batteries (LIBs), their safety performance under extreme conditions has become a focal point of industry concern. As the core component of new energy technologies, the reliability of LIBs is directly linked to the safety and efficiency of critical sectors, including electric vehicles (EVs) and energy storage systems (ESS). I. Failure Mechanisms in Extreme Environments Lithium-ion batteries undergo complex electrochemical degradation when exposed to thermal extremes: Low-Temperature Environments (e.g., -40°C): At sub-zero temperatures, the electrolyte viscosity increases significantly, leading to higher ionic transport resistance and a sharp decline in discharge capacity. Concurrently, non-uniform

"Silent Alarms" in NCM Batteries: How 6 Key Gases Dictate Battery Safety and Longevity

"Silent Alarms" in NCM Batteries: The Interplay Between Gas Generation, Battery Safety, and Battery life During the battery formation stage—the final step before a brand-new NCM (Ternary) battery leaves the factory—the volume of gas discharged is enough to make any engineer frown with concern. These invisible gases are quietly dictating the battery’s future lifespan and its safety boundaries. As the market share of New Energy Vehicles (NEVs) surges, batteries now account for over 50% of a vehicle's total cost, making safety and longevity the top priorities for consumers. Ternary lithium batteries, particularly high-nickel systems, are widely favored for their high energy density. However, the gas evolution that occurs during cycling

How to make a coin cell? 2026

How to make a coin cell? The following are the materials, equipment, and assembly steps required to make a coin cell. The performance of new battery materials in lithium-ion batteries is usually evaluated with hand-made half coin cells with the new material as the positive electrode and a piece of lithium chip as the negative. Half coin cells are easy to make and can give reproducible data. A full cell in the form of coin cells or pouch cells would more accurately predict the performance of active materials in real lithium-ion batteries. PPE: Lab goggles Gloves Lab coat N95 respirator (optional) Materials for making a coin cell: Electrode powder: LiCoO2

2025 Breaking the fast charging bottleneck! Superwettable Electrolyte Engineering for Fast Charging Li-Ion Batteries

Breaking the fast charging bottleneck! Shanghai Jiao Tong University & Southern University of Science and Technology join forces: Super-wetting electrolyte reshapes the SEI layer, comprehensively improving lithium battery performance. Recently, Professor Wan Jiayu's team at Shanghai Jiao Tong University, in collaboration with Professors Liu Ke, Luo Guangfu, and Deng Yonghong from Southern University of Science and Technology, published a groundbreaking study in the top journal ACS Energy Letters (IF: 22.0). They proposed a general "stepwise liquid injection" interface engineering strategy, successfully constructing a uniform, stable, and inorganic-rich SEI layer on a graphite anode using an ultra-low concentration of superwetting electrolyte. This breakthrough overcomes multiple bottlenecks in wettability, SEI stability, and
