Lithium batteries are considered one of the best solutions for small and large-scale electric systems, thanks to their longevity and limited weight, and this makes them the new frontier for storage in the field of electrical mobility. They do however, also have 2 main issues: they lose a good amount of energy due to overheating and they also deteriorate quite easily. Ju Li, Battelle Energy Alliance Professor of Nuclear Science and Engineering at MIT confirms: "You waste 30% of the electrical energy as heat in charging. It can actually burn if you charge it too fast." But Ju Li has come up with a solution that promises to revolutionize the world of energy storage for lithium batteries, thanks primarily to a new model called "nanolithia cathode battery." Essentially, thanks to the nanolithia, oxygen does reach the external part of the battery, and the charging process takes place within a closed and sealed circuit which avoids dispersion. This reaction was also at the base of the fast deterioration of the batteries. The solution found by MIT promises instead at the same time to extend the life of the storage plants, whether it be systems for electric equipment of batteries for electric cars.
