Mahle enters the competition, his battery can be recharged in 90 seconds

Recharge in 90 seconds with a rare metal free and fully recyclable battery. Now Mahle also comes into play with one of his prototypes.

La Mahle Company has developed a lithium-ion battery that could enable fast, lightweight charging in just 90 seconds. Sure, it's too small to be useful on larger cars that consume more fuel, but for two wheels it's perfect. Maybe even for very light tricycles and quadricycles.

The company says 90-second charging technology would make electric vehicles even faster and more practical for short trips and city distribution. Clear as day. The car's battery performance Mahle (in a smaller version) could also be used in consumer electronics.

Little giants to recharge

There's more: the battery technology proposed by Mahle does not use rare metals, and will be completely recyclable. A great success also in terms of the necessary environmental sustainability. Recharging your batteries to "discharge" the environment is no longer a viable option, and fortunately so.

The new battery concept is currently in the prototype phase. It essentially combines the advantages of conventional lithium-ion batteries and those offered by supercapacitors. Not only does it offer fast charging, therefore, but it has a high power density and also low self-discharge. For the more technical I would also add that it doesn't have any thermal runaway (the less technical can click the link to understand what it is).

Next steps

This lithium-carbon battery concept it was presented on the occasion of the Achen Colloquium, a symposium event of industry experts held in Aachen on 5 and 6 October.

At the event, Mahle presented not only the battery that can be recharged in 90 seconds. The company's plans also include an integrated thermal management system for battery electric vehicles. With this system, the manufacturer wants to optimize the overall efficiency of the vehicles. Its introduction could reduce costs and allow the integration of motor, electronics and battery temperature control into the entire system.

Ambitious goals, which will take (yes, I'm sure) well over 90 seconds.
