Thus, the batteries can be charged at high temperatures and not explode. A single charge should last for 300-500 miles, confident engineers.

American chemists and engineers has created a new type of lithium-ion batteries that can be charged at high temperatures and not explode. This will allow you to charge electric cars in 10 minutes or even shorter time, the press service of the University of Pennsylvania in Philadelphia, citing a publication in a scientific journal Joule.

“Our battery will allow electric vehicles to drive about 320-480 km after only ten minutes of charging. And we can maintain this pace of work for 2.5 thousands of cycles of charge and discharge, that is not the equivalent of approximately 800 thousand kilometers,” – said one of the authors Chao-Yang Wang of the University of Pennsylvania.


Modern batteries consist of three parts – the cathode, anode and electrolyte. The first plays the role of the positive pole of the energy source, the second negative pole and “esimates” current, and the electrolyte allows charge carriers to travel between the cathode and the anode. The power of the batteries depends on the composition of the cathode, and their longevity – how much is destroyed, the material of the electrolyte and cathode during the discharge cycles of the charge.

From design all the components of the battery depends on how dangerous they are to humans. For example, many types of modern lithium-ion batteries explode due to the fact that in case of overheating inside, they begin to occur a short circuit. They are even more heat the battery, vaporize the electrolyte, turning it into bubbles of hot gas that eventually leads to melting of the battery and explosion. Such concerns, as noted by Chao-Yang Wang, interfere to create a truly affordable and convenient electric vehicles, as the process of “refueling” takes several hours.

The authors found an ingenious solution to this problem by examining what happens inside the heated battery during charging and discharging. They found that most of the negative effects can be avoided, if you connect one of the electrodes with a thin film of Nickel, which evenly heats the battery. If you charge the battery for a relatively short time, about 10-20 minutes, then quickly cooling, its components will not break down.

Following this idea, researchers have gathered several experimental batteries, loaded them and saw there inside them the so-called “whiskers”. So scientists call the thin filament and plate of pure lithium metal, which is caused by a short circuit. They are the reason that the batteries warmed up and explode.

As shown by these experiments, the lithium whiskers really are not generated, even when the battery when charging time to heat up to 60 degrees Celsius. However, she can withstand almost two thousand cycles of charge-discharge, whereas the conventional battery through which is passed a current of the same strength, fails after about 60 cycles.


Most importantly, modification of the battery increased its total cost by 0.46% due to the added Nickel. This, as scientists hope, will allow the invention to quickly penetrate into the industry to help electric cars become more attractive to consumers.

Change on the electric car, if it will charge in 10 minutes?
