IBM has created new lithium-ion cells without cobalt and nickel. Loading up to 80% in 5 minutes more than 0,8 kWh / l!
New lithium-ion cells from the IBM research lab. They use "three new materials" and the battery made from them can charge up to 80 percent in less than 5 minutes. They do not use expensive cobalt or nickel, which could reduce the price of electric vehicles in the future.
New elements from IBM: cheaper, better, more efficient
already In 2016, cell and battery manufacturers consumed 51 percent of the world's cobalt production.... Some scientists expected the increased interest in electric vehicles would drive up the price of the metal as its availability is limited. And this despite the fact that many companies are working to eliminate this element from lithium-ion batteries.
Rising cobalt prices are slowing down the decline in electric vehicle prices. They will remain close to the current level:
> MIT report: Electric cars won't drop in price as quickly as you think. More expensive in 2030
meanwhile IBM cell cathodes are free of cobalt, nickel and heavy metals.and the elements used in them can be extracted from seawater (source).
As the the cost of a battery today is about 1/3 the cost of an electric car., the cheaper the elements that make up the cells, the cheaper the final price of the electric vehicle is lower.

In addition, they used it high flash point liquid electrolyteswhich can be important in case of accidents. Moreover, modern electrolytes are highly flammable.
IBM says it has tested a battery from its cells configured to support high power. She made it charge up to 80 percent in less than 5 minutes... This would mean stopping at the charging station for about the same time as refueling.
The manufacturer promises that the new cells will create batteries that perform better than current lithium-ion cells. For example, they will provide a power of more than 10 kW per liter of battery (10 kW / l) and are already capable of reaching an energy density of more than 0,8 kWh / l.
By comparison, CATL boasted this year that the latest generation of lithium-ion cells with a nickel-rich cathode has reached 0,7 kWh / l (and 0,304 kWh / kg). And TeraWatt claims to have developed solid electrolyte cells with an energy density of 1,122 kWh / L (and 0,432 kWh / kg):
> TeraWatt: We have solid electrolyte batteries with a specific energy of 0,432 kWh / kg. Available from 2021
The cell research was carried out by IBM in collaboration with Daimler, the owner of the Mercedes-Benz brand.

Editor's Note www.elektrowoz.pl: 2016 Cobalt Consumption data from the Cobalt Institute. We quote them because in the article “Fully Charged” for cobalt the situation is somewhat exaggerated. Although it is a fact that cobalt is also used to process crude oil (= fuel production).
