At the onset of the 20th century, electric cars powered by lead-acid batteries outnumbered gas-powered cars. The internal combustion engine ultimately won out, in part because those batteries had a range of just 30 miles. But Thomas Edison believed a nickel-iron battery could extend that range to as much as 100 miles, while also having a long life and recharging times of seven hours. An international team of scientists has revived Edison's concept of a nickel-iron battery and created their own version, according to a paper published in the journal Small.
