The revolution among electric vehicles: created a battery that charges in minutesFebruary 17, 2019
American scientists from Purdue University have developed a membrane-free flow-through battery, thanks to which electric vehicles will be charged in just a few minutes.
Now the usual recharging of a lithium-ion battery of an electric vehicle takes from 6 to 8 hours. It is quite enough that during the night the battery is fully replenished with energy. There is also the so-called fast recharging, when the battery with a special device charges up to 80% in about 30-45 minutes. But for such a device you need to pay extra.
Every owner of an electric car is very important for how long it is possible to charge its battery. And the faster – the better.
Earlier, in non-membrane flow-through batteries, the energy density did not exceed 20 Wh / kg, while for lithium-ion batteries, this figure was 130-140 Wh / kg. Naturally, preference was given and is given to lithium-ion batteries.
But this situation may change soon. Already have a flow-through battery with an energy density of up to 1300 Wh / h. However, it has a small size.
In such a battery, single-fluid technology produces electrons by oxidizing the anode. At the cathode is undergoing a recovery process, electricity is produced. The electrolyte is drained after use, and the waste liquid can be recharged.
In the near future, Americans are planning to test their new battery on electric vehicles in road conditions. If everything goes well, after two or three years, these batteries will become commonplace in the automotive industry.
