Supercapacitors, which unlike accumulators are charged in seconds, not hours, differ much faster self-discharge. Scientists at Drexel University offered the best option and developed batteries based on nanomaterial MXene, which offers charging in fractions of a second, so that in the future, users can almost instantly charge a smartphone or electric car.
The flat battery design contains a metal and hydrogel structure. According to the researchers, in the laboratory such batteries replenish the capacity for "tens of milliseconds".
As usual, the technology will be difficult to implement in commercial battery designs, and the development of the product on the market can take years. Meanwhile, the MXene project will make ultra-fast charging more realistic.
