New technology promises batteries with a life of 30 years

Researchers at Stanford University yesterday released a study suggesting that the batteries of the future will have a lasting incredibly larger than we can now conceive. According to university research, such batteries will be able to be used for up to 30 years without showing significant decreases in their energy storage capacity.


According to the authors Colin Wessells, Robert Huggins and Yi Cui, the secret lies in a new construction technology developed from nano engineering, using an alloy of copper and iron loaded with potassium ions. "Potassium is able to carry a positive and negative without degrading, allowing the construction of a battery of high power," said lead researcher Yi Cui in an article published in the journal Nature.

According to scholars the new model is capable of supporting up to 40 000 cycles of loading and unloading without showing wear and tear. Compared to current models of lithium ions, which do not usually support more than 500 cycles without losing much of its capacity, this represents an improvement of up to 80 times more cycles.

Like all development in the area of ​​batteries, you should still take a long time before they appear on phones and computers, since the cost and technology needed to produce their pa alloy of copper and iron is still far beyond the reach of large companies.
