The first battery, a pile of copper and zinc discs, was invented more than 200 years ago, ushering in the electric age. Subsequent versions led to portable electronics, mobile computing, and our current love affair with smartphones (1,000 of which are shipped every 22 seconds). Now batteries are powering electric cars and storing electricity produced by solar cells and windmills, but they don’t last long enough and are too expensive for either use to really go mainstream. To cut the cost, Tesla plans to double the world’s production capacity of the popular lithium-ion battery with its forthcoming $5 billion battery manufacturing plant in the Nevada desert. Tesla’s idea is to use economies of scale to lower prices. Meanwhile, other companies and many industrialized countries, including China and the U.S., are racing to develop batteries that are more advanced than Tesla’s. They’re betting billions that breakthrough battery technologies will help create new industries, juice existing ones, and wean us off fossil fuels because we’ll be able to use the sun and wind in their place. Here is a book, a documentary, and five stories on our battery-powered future.
