New membrane does not allow the battery to lose charge
Scientists at the Ohio state University has designed a thin plastic membrane that prevents the batteries to be discharged when they are temporarily idle, and accelerate the replenishment of energy. Thus, they hope to improve the rate of 0.4 miles per minute charge, which is typical of most electric cars.
Patented technology, reminiscent of the transport proteins in the living cell, controls the charging process and should find application in supercapacitors for electric vehicles and to prevent fire, which became a real disaster for hoverboards.
Even the best lithium-ion batteries will eventually lose charge, because the membrane does not fully cope with this task. The battery heats up and may burn. Membrane Vishnu Baba Sundaresan and his colleagues — conductive polymer with a polycarbonate filter, the size of the holes which scientists could control. When the battery is being charged or discharged, the polymer reveals holes. When the battery is not in use, they are closed.
Engineers of the University I hope that the smart membrane will allow to develop a new type of powerful batteries with fast charging, "okisliteljno recovery transistors, which will help increase the vehicle range of the electric car".
In parallel, they analyzed the performance of leading batteries for hybrids and electric vehicles, and found that, in their opinion, had never been fully formulated. The best eco-friendly cars has reached its performance limit, and that limit is 0.4 mile (0.6 km) per minute charge.
In other words, today, the best electric cars passing about 320 km after 8 hours of charging, while the diesel can cover the same distance after only a minute spent at the pump at the gas station.
Ohio scientists hope that their invention will allow to pass dozens of miles per minute of charge. "It's still an order of magnitude less than gasoline cars, but it's a start," says Sundaresan, the head of research. published
