Electric Vehicles

Electric mobility is one of the most important efforts in the global fight against climate change. However, in order to truly compete with internal combustion engine vehicles, the cost of electric vehicles needs to decrease and the vehicle range needs to increase. Today's options are a $30K vehicle that travels 90 miles per charge or a $100K vehicle that travels 270 miles per charge -- neither of which appeals to the general population. Envia's technology dramatically reduces battery costs through low cost electrode materials and high energy density cells, ultimately reaching $100/kWh. Envia's first generation electric vehicle cell is 234 Wh/kg, using a manganese rich cathode and graphite anode. Envia's second generation cell will utilize its silicon based anode, enabling much higher energy density.
