Battery developers continue to push for supercharging lithium batteries . Researchers recently unveiled a nanowire electrode that could more than triple lithium batteries’ energy storage capacity and improve their safety. Nanowires of silicon just a few atoms across can absorb and release about 10 times more lithium ions than the graphite electrodes that are commonly used today.
Additional advances will be required before lithium batteries with nanowire electrodes deliver major increases in performance of electric-vehicle is the need to scale up the process of making nanowires, which have yet to be mass-produced for commercial application. Another limitation is that while silicon nanowires make great anodes, lithium-battery technology has greater need for improved cathodes. Labs are working on novel materials for cathodes. That is the holy grail for this business. Anyone who can generate much higher cathode capacity will bring a huge breakthrough.
