Silicon Anodes Muscle in on Battery Technology

Silicon is a staple of the digital revolution, shunting loads of signals on a device that's likely just inches from your eyes at this very moment. Now, that same plentiful, cheap material is becoming a serious candidate for a big role in the burgeoning battery business. It's especially attractive because it's able to hold 10 times as much energy in an important part of a battery, the anode, than widely used graphite.

Tracking Pileups on Battery Charging Route to Drive Performance

Because of their high storage capacity, metal oxides are a promising class of potential conversion-type electrode materials for next-generation lithium-ion batteries. Conversion-type electrode materials undergo conversion reactions; when they react with lithium ions, they get converted into entirely new products. Today's commercial batteries are based on a completely different mechanism called intercalation.
