PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. A paper on the work appears in Nature Energy.

DOE awards Cummins $5M for automation of electrolyzer cell and stack assembly

Green Car Congress

To dramatically reduce greenhouse gas emissions and meet ambitious climate goals, we must invest now in scaling electrolyzer manufacturing and green hydrogen production to create a viable zero-emissions ecosystem. When any type of electrolyzer is powered by renewable energy sources, such as wind, solar or hydro, it produces “green” hydrogen.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. This can leave much of the surface area exposed to electrolyte, accelerating unwanted chemical reactions induced by high nickel content and generating gas.
