New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. We decided we needed to develop a new chemistry if we were going to make low-cost batteries and battery electrodes for the power grid.

Researchers develop optimal silicon disulfide production technology for solid-state batteries

Green Car Congress

Researchers from the Korea Electrotechnology Research Institute (KERI) and Kumoh National Institute of Technology (KIT), have developed a low-cost production technology for silicon disulfide (SiS 2 ) for solid-state electrolytes (argyrodite-type) that has potential to accelerate the commercialization of all-solid-state batteries (ASSBs).

New high-activity, low-cost nickel-based catalyst for fuel cells exhibits performance similar to Pt; hydroxide exchange membrane fuel cells

Green Car Congress

Owing to its high activity and low cost, the catalyst shows significant potential for use in low-cost, high-performance fuel cells, the team suggested. Pt is the most active catalyst for both HOR and ORR; the high price of the metal (~$50 g −1 ) has hindered fuel cell commercialization. —Zhuang et al.

Who Will Free EV Motors from the Rare Earth Monopoly?

Cars That Think

The peak efficiency of the GE motor was 94 percent, on a par with the best motors used today in commercial EVs. GE Aerospace declined to make a researcher available to be interviewed for this article.) But technical advances are probably not the highest hurdle to commercialization, he adds. It’s not only about GE. “A
