The price of electric car batteries is plummeting, and it could just be the catalyst to the electric car revolution. The price of lithium-ion battery packs has fallen 65 percent since 2010, with experts predicting that trend will only continue in the coming years. These low prices are enabling car companies such as Volkswagen and General Motors to become competitive in the electric car market, as well as other companies such as Google. As prices continue to fall, expect to see more electric cars on the roadways in the coming years.
