Super lithium battery Made in Italy: the most powerful and safe

It is an evolution of the common lithium-ion battery, but compared to these is much more efficient and secure. The superbatteria made by the team of researchers led by Professor Bruno Scrosati Rome's La Sapienza mainly serve to fuel electric cars, thanks to its high autonomy and remarkable thermal stability.

The study conducted by Jusef Hassoun and Bruno Scrosati of Wisdom, in collaboration with Yang-Kook Sun Hanyang University in Seoul, is published in the prestigious journal Journal of the American Chemical Society.

"Basically - said Bruno Scrosati - these batteries lithium ion generation reach, with a full tank of electricity, an autonomy of 210 km compared to 150 batteries available today." Also superior performance in terms of power and capacity.

"The new battery - adds Scrosati - relies on the combination of nanostructured electrodes, one of tin-carbon and the other of lithium oxide" doped "with manganese, nickel and cobalt."

This particular combination electrode allows operations with hundreds of charge cycles without a reduction in capacity and charge-discharge efficiency approaching 100%.

In addition, the new materials are abundant in nature and have a higher thermal stability than those used in ordinary lithium-ion battery.

This would help ensure lower costs affecting the price of batteries for electric cars (still quite high) and reduce the risks arising from excessive heating, weakness of the current power supplies.

Such benefits suggest that the new battery can be adopted as an effective propulsion system for electric motors in environmentally friendly cars (hybrid or electric), thus contributing to the sustainability of our planet.
