It transports sodium – which is found everywhere on earth – instead of lithium. The lithium batteries that power our electronic devices and electric vehicles have a number of drawbacks. The electrolyte – the medium that enables electrons and […]

Research leader Dorthe Bomholdt Ravnsbæk of the Department of Physics, Chemistry and Pharmacy at University of Southern Denmark pointed out, “The Na-ion battery is still under development, and researchers are working on increasing its service life, lowering its charging time and making batteries that can deliver many watts.” Now the race is on to develop […]

A French team has announced a design and chemistry alternative technology to Lithium-ion for application in specific sectors. The researchers have developed the first battery using sodium ions in the usual “18650” format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less […]

A Battery For The Grid

October 10, 2011 | 4 Comments

Aquion Energy in Pittsburgh uses the simple chemistry of water-based electrolyte and abundant materials such as sodium and manganese for a grid scale battery that is expected to cost $300 for a kilowatt-hour of storage capacity, less than a third of what it would cost to use lithium-ion batteries.  Third-party tests have shown that Aquion’s […]
