Battery breakthrough could bring electric cars to all — Cleantech News and Analysis

Kapadia tells me that current lithium ion batteries deliver an energy density of around 100 to 150 watt-hours per kilogram, while Enviaâ€™s battery can deliver 2.5 times that energy with about the same weight as the current electric cars that have hit the market. To build a 300-mile range electric car with standard lithium ion batteries, it would cost around $40,000 just for the batteries alone, says Kapadia.
Envia says with an energy density of 400 watt-hours per kilogram, its battery cell costs could be at $125 per kWh. Tesla CEO Elon Musk has said recently that he sees battery cells dropping in price to below $200 per kWh in the coming years. Current electric cars like the Volt have been reported to be closer to $500 to $600 per kWh, and the Nissan LEAF at $375 per kWh.
