Electric cars, all the discoveries to recharge in a flash

Surely the batteries that will be able to make the leap in quality to zero-emission cars will be more capacious, but above all faster to recharge. Many think that to achieve this goal we still need to evolve the lithium ion technology (which today is the dominant one), which still includes margins of improvement and development, others instead think of other solutions, sometimes even a bit fanciful.

Each study among those collected follows its own unique path, the first one we consider for example is that of Argonne National Laboratory, which thinks it can halve the charging time with lithium-manganese oxide instead of simple lithium, combined with a transparent casing.

Many are the studies that argue that if we change the approach to electrolyte we can speed up recharging, using a liquid loaded with energy and replaceable that would make the refueling just similar to that of petrol or diesel to which we are accustomed and also the times could become similar. The only contraindication it would be the need for a large amount of fluid to have the same energy as a good battery.

According to Penn State University instead the solution to increase the charging speed would be the preheating of the batteries, which would also improve their durability. This method would hinder the formation of the plaques responsible for the deterioration of battery life and their performance.

There Piech Automotive he even thinks otherwise, at the last Geneva Motor Show he presented the Mark Zero supercar which should be loaded up to 80% in just 5 minutes, according to them, by cooling the batteries, lowering their operating temperature to recharge.

Finally, in the project presented by ABB, working on the refill itself is the only way to get big performance and therefore use a very high power column, even up to 350 kW able to recharge in just eight minutes an electric car for a range of 200 km. This is the same structure used to recharge the cars of the Formula E championship.
