Silicon’s Rally

Battery anode materials are made predominantly from natural graphite or synthetic graphite. But battery technology rarely stands still and pure silicon anodes promises to offer greater energy density in batteries. Paul Harris explores the advances in silicon anode technology, the companies developing them, and the obstacles to adoption.
The quest to improve lithium-ion battery performance seeks to produce batteries that can hold a greater charge to increase the time between charges, to decrease charging times, cost and other performance parameters. While much of the news has focused on cathode formulations and how much nickel or cobalt they . . .
