Revolutionary New Vanadium Battery Technologies Two “next generation” Vanadium battery technologies could create a brand new market for Vanadium in the near future and could play a major part in solving the global energy crisis.
1) Vanadium Redox Flow Battery
Allows charging and discharging of energy as available and as needed and is already being implemented in various countries for power grids, factories and various other applications.
Vanadium redox batteries or cells (“VRB”) were invented in Australia and is a proven technology that has been implemented in various power grids and locations around the world.
VRBs contain a vanadium ion solution as an electrolyte in positive and negative electrodes. Electrolytes circulate in the battery cells and charge/discharge, simply changing the vanadium ion state and resulting in an indefinite life.
VRBs have the ability to simultaneously charge at one rate, while discharging at another and can be scaled virtually up or down to any size application.
VRBs may be fully discharged without damage and do not have a memory if recharged before being fully discharged.
Environmentally friendly, VRBs do not discharge any harmful exhaust gases such as CO2. And, unlike other batteries and do not generate heat.
VRBs are the world’s most cost-effective source for a clean, reliable, in-line, uninterruptible electric storage which is ideal for power generated from wind, solar and hydro.
2) Vanadium Lithium Ion battery
Is fast approaching commercial implementation for various electronics and could for the first time, make electric vehicles commercially viable. These applications would require an large supply of vanadium. Below is a more detailed description of these two emerging technologies that promise lower cost energy and a cleaner environment.
Over the past thirty years, Hydro Quebec and 3M have been involved in the initial research and development of a solid state fuel cell for hybrid electric vehicles, electric vehicles and communication applications.
Most major car manufacturers are joining the electric vehicle or “EV” revolution sparked by GM’s announcement in September 2008 of the “Volt.”
“We expect Chrysler’s announcement will accelerate the development of affordable electric vehicle technologies such as batteries” GM E-Flex spokesperson Rob Peterson
Given previous attempts at EV commercialization in the past, the currently proposed lithium-ion battery technology still does not seem to be the ideal candidate for various promised 2010 EV launch dates.
In November 2007, Subaru unveiled their concept G4e electric vehicle with a lithium vanadium oxide based lithium ion battery, promising double the energy density of a conventional lithium ion battery.
In the lab, Lithium vanadium oxide anodes, paired with lithium cobalt oxide cathodes, have nearly three times the volumetric energy density of conventional lithium ion batteries.
