Scientists at Stanford University have accidentally discovered that a battery consisting of a negatively charged anode made of aluminum and a positively charged cathode made of graphite offers many benefits over conventional lithium-ion batteries including faster charging.
They reportedly were able to charge a smartphone in just one minute, so it's pretty safe to assume you could fully charge an electric car's battery in a few minutes only.
Another benefit of aluminum-graphite batteries is a low cost. Both of these materials are widely available in the industry, so they could help reduce the price of electric vehicles significantly. Aluminum is also known for its low flammability and high-charge storage capacity, making it an attractive material for batteries. Graphite, meanwhile, offers high electrical conductivity.
"Our battery produces about half the voltage of a typical lithium battery," said Hongjie Dai, a chemistry professor at Stanford. "But improving the cathode material could eventually increase the voltage and energy density. Otherwise, our battery has everything else you'd dream that a battery should have: inexpensive electrodes, good safety, high-speed charging, flexibility and long cycle life. I see this as a new battery in its early days. It's quite exciting."
