The Australians have created a hybrid of a supercapacitor and a battery | |

Scientists have long been trying to give lithium batteries the properties of supercapacitors, so that charging is relatively instantaneous and that the output power is at a decent level. Modern lithium batteries in the complex provide the same electric cars Tesla about 1000 horsepower. Just imagine if a Tesla battery was a supercapacitor! Then under the hood of electric cars of this brand could accommodate up to five thousand horses! It would be a supercar! Researchers from the Queensland University of Technology in Australia have created a hybrid battery, which has a negative electrode like a supercapacitor — a titanium carbide plate for storing static charge, and a positive one-like a typical lithium battery with the ability to store lithium ions in graphene. The output is a battery with fast charging capability-about five times faster than a typical lithium cell, but with a significantly higher capacity than a supercapacitor — about the same as a NiMH battery. If we turn to the figures, the hybrid element of the Australians provided a capacity of 73 Wh/kg, which is approximately 28 % of the capabilities of modern lithium-containing batteries, while its specific power reached a whopping 1600 W/kg, since fast charging also implies fast discharge, which means the return of more power in a shorter time. | |
