Branched nanostructures for battery electrodes

摘要

The invention relates to electrochemical electrodes containing branched nanostructures having increased surface area and flexibility. These branched nanostructures allow for higher anode density, resulting in the creation of smaller, longer-lasting, more efficient batteries which require less area for the same charging capacity. Also disclosed are methods for creating said branched nanostructures and electrodes.
