New research has identified a nanostructure that improves the anode in lithium-ion batteries Instead of using graphite for the anode, the researchers turned to silicon: a material that stores more ...

Materials science ain’t easy. And it’s especially difficult when it comes to the batteries that power our smart home, wearable, and mobile devices; more specifically, lithium-ion (Li-ion) batteries.

A Stanford team, led by the battery master himself -- Yi Cui -- has developed a new lithium-ion battery electrode that still works at 85% capacity after 6,000 charge/discharge cycles, compared to ...
