Many are working on extending the range of electric cars. Here are three of them. Firstly TreeHugger believes that replacing the graphite electrodes in lithium-ion batteries with silicon nanotube electrodes,would multiply the range by ten.
ArsTechnica notes that carbon nanotubes in ultracapacitors ” may make sense in electric cars, even if it can’t store as much as a battery.” Thirdly, IBM is launching a project to enable electric cars to have a range of 500 miles (800 km).
Extending the current range of electric vehicles and cutting the costs of batteries are the two necessary steps to allow mass market commercialization.
