A new lithium-ion battery is being developed at USC that can be recharged in 10 minutes and hold three times more energy than other batteries. They first experimented with highly conductive and porous silicon nano-wires as the battery’s anode, but found that these nano-wires are difficult to manufacture in mass quantities. So they took commercially available nano-particles of silicon spheres and etched them with the same pores as the nano-wires. This is how they came up with these batteries that have 10 minute recharge times. They believe that such batteries should be commercially available within two to three years.
