Wildcat Discovery granted patent for Li-ion electrolytes that improve performance of silicon anodes

Wildcat Discovery, a battery research company based in San Diego, has been granted a patent for the use of sulfolane-based electrolytes designed to improve the performance of Li-ion batteries containing silicon anodes. In 2013, the company was awarded a grant by the DOE’s Office of Energy Efficiency and Renewable Energy to develop new non-carbonate-based electrolytes… Read more »

Carbon nanotubes help make lithium metal batteries more durable

Carbon nanotubes could make high-powered, fast-charging lithium metal batteries an alternative to lithium-ion batteries, according to new research from Rice University. In a paper published this month in the journal Advanced Materials, the researchers show how a carbon nanotube film can be used to keep batteries safe from dendrites, spear-like protrusions that naturally form on… Read more »

CAMX Power’s new GEMX cathode material

CAMX Power, an independent lithium-ion battery materials and design firm, has announced a new class of cathode materials that it says improves upon the high-nickel material classes NMC, NCA and LNO. The patented invention is called GEMX, and the resulting enhanced chemistries are called gNMC, gNCA and gLNO. High-nickel cathode chemistries for vehicle batteries use… Read more »
