Advano

Researchers following the traditional design for recharge­able lithium-ion batteries — using a graphite anode and metal oxide cathode — are squeezing out smaller and smaller improve­ments at greater and greater cost. Advano changes that, turning scrap silicon waste into a new form of 3D nanos­truc­tured silicon that can be added to the graphite anode at an affordable cost to build batteries with higher energy density.
