A Nanowire battery is an lithium ion battery invented by a team lead by Yi Cui at Stanford University. The team's invention consists of a stainless steel anode covered in silicon nanowires to replace the traditional graphite anode. Silicon, which stores ten times more lithium than graphite, allows a far greater energy density on the anode, thus reducing the mass of the battery. The high surface area further allows for fast charging and discharging.
