TITLE:                     Vanadium in Batteries

ABSTRACT:           

                             Vanadium is a hard and ductile transition metal that has received a great deal of attention in the last decade due to its role in the Vanadium Flow Redox Battery (VRBs) and in Lithium Ion Batteries. Due to the increasing demand to store renewable energy, VRBs have become popular in the USA, Europe and China. These batteries utilize the various oxidation states of vanadium to store chemical potential energy, resulting in a battery with a high storage capacity, rapid charging times, and the ability to discharge very quickly. Over recent years, all components of the battery, including the electrolyte, membrane and electrodes, have been improved upon, in order to achieve the high energy, voltage and columbic efficiencies required to produce a viable energy storage device. In a second application, the addition of vanadium phosphates to the cathode of Li ion batteries not only increases Li ion battery safety, but it also increases the operating voltage, and thereby power.  This particular discovery is expected to be quintessential in the commercial implementation of practical electric vehicles.
