UC Riverside team fabricates nanosilicon anodes for Li-ion batteries from waste glass bottles

Green Car Congress

Researchers at the University of California, Riverside’s Bourns College of Engineering have used waste glass bottles and a low-cost chemical process to fabricate nanosilicon anodes for high-performance lithium-ion batteries. An open access paper describing the research was published in the Nature journal Scientific Reports.

BMW i home energy storage system integrates 2nd-life i3 vehicle batteries

Green Car Congress

The battery storage system also includes a voltage converter and power electronics to manage the energy flow between renewable energy sources, the house interface, and the Li-Ion high-voltage battery from the BMW i3. This approach minimizes energy waste, effectively reducing energy costs on a day-to-day basis.
