New batteries are the highest capacity Molten air batteries for cars, grid balancing

Researchers have developed a new class of batteries, the melt without the battery, which they say is the largest natural energy capacity of any laptop external battery charger yet.
Chemistry Professor Stuart Licht George Washington University, USA, have developed a battery that uses air and molten electrolyte. Iron-based battery energy capacity of about 10,000 Wh / l, carbon-based battery has a capacity of 19,000 Wh / l and VB2, capacity is 27,000 Wh / L. The standard lithium-ion battery has a capacity of 600 Wh / L.
The high energy capacity, the battery pack is suitable for different uses, such as adding a variety of electric vehicles and energy storage power grid, to help balance intermittent power supply from Renewable sources of energy.
During the melt, the battery operates at very high temperatures of 700-800 ° C. The researchers tested three molten salts containing iron, carbon and vanadium boride (VB2) to conserve energy. how to increase laptop battery life, used nickel electrode, which facilitates the use of oxygen battery discharge. Iron oxidizes Fe (III) an electron donor. When the battery is charged, the Fe (III) is reduced back to iron. When carbon-based batteries, carbon is oxidized carbonate ions, while VB2 will V2O5 and B2O3.
At this moment, this new class of battery is only a proof of principle, and the researchers say the various parameters, such as electrolyte and the composition and temperature, it is necessary to optimize the universal external laptop battery the temperature can be reduced if the composition of the electrolyte is changed.
"The main elements (inorganic salts, iron and nickel) are readily available and affordable," said Licht tec. "Depending on the number of scale-up and engineering company, we can see the blade without batteries used in practical applications in two years' time."
