Battery breakthrough could bring electric cars to all |  GigaOM A startup working on battery technology says it’s developed a key breakthrough that could one day lead to an electric car that has a 300-mile range and could cost around $25,000 to $30,000. Envia Systems, backed by venture capitalists, General Motors, and the Department of Energy, plans to announce on Monday at the ARPA-E conference that the company has created a lithium ion battery that has an energy density of 400 watt-hours per kilogram, which Envia CEO Atul Kapadia told me in an interview could be the tipping point for bringing electric cars to mainstream car owner. The secret sauce Energy density is how much energy a battery can store and provide for the car with a given battery size — the more energy dense the battery, the less volume and weight is needed. For electric cars it is particularly important to have a high energy dense battery because electric cars need to be as light weight as possible (any extra weight just drains the battery faster), and batteries that are smaller and use less materials can also be lower in cost

The secret sauce

Energy density is how much energy a battery can store and provide for the car with a given battery size — the more energy dense the battery, the less volume and weight is needed. For electric cars it is particularly important to have a high energy dense battery because electric cars need to be as light weight as possible (any extra weight just drains the battery faster), and batteries that are smaller and use less materials can also be lower in cost

    Think of it, a car that could run on electricity and gon300 miles. That would be a game changer for sure . Of course, it...
