A research team from CAS QIBEBT has developed a new homogeneous cathode material, which will enable solid lithium batteries to have higher safety and superior performance, has not yet been named. It achieves over 1,000 times the electronic and ionic conductivity of traditional battery cathode materials. It can smoothly undergo charge and discharge cycles without conductive additives, which simplifies the battery preparation process and also improves the performance of the all-solid-state lithium battery.

Homogeneous cathodes were composed of 100% Li_1.75Ti₂(Ge_0.25P_0.75S_3.8Se_0.2)₃ enable room-temperature all-solid-state lithium batteries to achieve a cycle life of over 20,000 cycles at 2.5 C with a specific capacity retention of 70% and a high energy density of 390 Wh kg⁻¹ at the cell level at 0.1 C. This cathode homogenization strategy contrasts to the conventional cathode heterogeneous design, potentially improving the viability of all-solid-state lithium batteries for commercial applications.

A lipid-rich baker’s yeast mutant provides high yields of palmitoleic acid

A team at CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) has developed a lipid-rich mutant strain of Saccharomyces cerevisiae for microbial production of palmitoleic acid— a rare omega-7 fatty acid with proven anti-inflammatory and metabolic benefits.

The team used a combined mutagenesis approach—employing zeocin, an antibiotic-based mutagen, and Atmospheric and Room Temperature Plasma (ARTP)—to create a diverse library of yeast mutants. They then deployed FlowRACS, a Raman flow cytometry system, to select live yeast cells with elevated lipid levels by analyzing their intrinsic single-cell Raman spectra, eliminating the need for chemical stains or genetic reporters.

This method identified the mutant strain MU2R48, which achieved a lipid content of 40.26%—a 30.85% increase over its parental strain SC018—while maintaining similar biomass production.

A hydrogen-powered tugboat in Qingdao port

https://j.people.com.cn/n3/2025/0627/c95952-20333735.html

The tugboat was designed and built by Shandong Port Qingdao Port Group Co., Ltd. and is equipped with a hybrid system of “hydrogen fuel cells + liquid-cooled lithium batteries” to achieve zero carbon dioxide emissions. It can sail for more than 12 hours at a speed of 9 knots and has a towing force of 82 tons. With technologies such as fully automatic smart on-shore charging, it has become the country’s largest port tugboat in terms of horsepower and lithium battery capacity.
