The lithium ion battery that lasts 3 times longer than normal

diciembre 2, 2019

John Goodenough, the creator of the lithium ion battery, has a battery that lasts three times longer than the current ones.

The chemistry of the lithium ion battery dominates in the electric car market, but also in consumer electronics as well as in numerous other applications. But this technology could be improved and to say it, first of all, there are the same creators of lithium batteries.

John Goodenough, a ninety-four-year-old professor from the University of Austin in Texas the Cockrell School of Engineering as well as co-inventor of lithium ion cells, then lithium ion battery, led a team of researchers who were able to offer a better alternative to the one currently existing

As stated in an article published in the journal Energy & Environmental Science, Goodenough and his colleagues argue that the their new battery can charge faster compared to the current ones and that it is not fuel.

This last quality obtained thanks to the solid-state battery design, which replaces the flammable liquid electrolyte – used in current lithium ion batteries – with a solid material. In this case, the electrolyte material solid the glass, which according to the researchers would reduce the cost of any battery sold, because it would allow the use of cheaper sodium, extracted from sea water, for the electrolyte instead of the lithium used in other Solid state batteries. According to researchers, performance would also be improved. The solid-state glass electrolyte battery can be charged and discharged faster, but it would last longer than lithium ion batteries. The experimental battery is three times more energetically denser, again according to the research team.

There energy density represents the amount of energy that can be stored in a given volume. The higher the energy density, the longer the range of duration will be increased without implying an increase in volume storage. Obviously this is laboratory research, nothing that can still be hypothesized in commercial terms. Even if it were, the transition from the design research to the consumer product stage could take several years. Some companies already sell solid-state batteries, although they are of a different type than the model proposed by Goodenough and his colleagues.

Solid state cells are used in BLUECAR electric cars, distributed by the French company Bollor in car-sharing services in the United States and Europe. QuantumScape and Sakti3 also tried to market solid-state batteries. Sakti3 was bought by Dyson, the British patent company famous for its bagless vacuum cleaners, in 2015 for $ 90 million.
