"The Sacramento-based start-up specializes in dry electrodes that eliminate the expensive, time-consuming wet-coating process. Wet coating involves the mixture of active materials, conductive additives and binders with a solvent to form a liquid slurry. This cathode and anode slurry then gets coated onto current collectors made from aluminum and copper foils, which are then dried in an oven at high temperatures."
"Nissan's glory days are well behind it. The automaker is trying to save itself after years of shrinking profits and sales. Its recovery plan includes layoffs, plant closures and a new wave of products, including electric vehicles and extended-range hybrids. But even in the middle of this challenging transition, Nissan isn't giving up on future technologies. The company is still betting big on solid-state batteries, and seems on track to be one of the first automakers to bring them to the market."
Nissan has reached performance targets for prototype solid-state battery cells and is working on processes to scale mass production. LiCAP Technologies supplies dry-electrode technology that removes the solvent-based wet-coating step, replacing slurry coating and high-temperature drying with a solid powder applied and flattened onto current collectors. Dry coating reduces material and processing steps but presents significant manufacturing challenges when scaled across large factories while maintaining low defect rates. The new cells could potentially double electric vehicle driving range. Nissan continues investing in advanced battery technology despite ongoing financial pressures that include layoffs and plant closures.
