Long-Range Electric Vehicle Batteries: High Energy Density Lithium Batteries
Broad Funding Opportunity Announcement Project: In a battery, metal ions move between the electrodes through the electrolyte in order to store energy. Envia Systems is developing new silicon-based negative electrode materials for Li-Ion batteries. Using this technology, Envia will be able to produce commercial EV batteries that outperform today’s technology by 2-3 times. Many other programs have attempted to make anode materials based on silicon, but have not been able to produce materials that can withstand charge/discharge cycles multiple times. Envia has been able to make this material which can successfully cycle hundreds of times, on a scale that is economically viable. Today, Envia’s batteries exhibit world-record energy densities.
