US Energy Dept. Hearts New Silicon EV BatteriesThis should bode very well for Purevap Nano NSiR
Very exciting times!
“In your electric car’s battery, swapping an electrode with one made of silicon could let the battery store 10 times more energy. Why isn’t silicon used? It falls apart,” explains the Energy Department.
Silicon’s superpower is its ability to expand in the presence of lithium. The problem is that silicon overdoes it and expands by about 300%, which breaks up the anode. In addition, silicon is too finicky to withstand conventional manufacturing process.
The solution is to figure out some sort of molecular glue that holds things together while still providing that boost in capacity and keeping costs down, too. Group14’s nanotech solution was impressive enough win the company an R&D award of almost $4 million for a project called “Rationally Designed Lithium Ion Batteries Towards Displacing Internal Combustion Engines.”
