Rechargeable lithium batteries are ubiquitous, and power most smartphones, laptops, and earphones, as well as game consoles, and many more.
And although the ubiquitous lithium batteries have radically changed the way we charge our mobile devices, this type of battery no longer appears to meet the growing needs of technology.
Over time, the performance of lithium batteries deteriorates, and defects in battery cells can sometimes lead to overheating and burning of devices, which has forced companies on more than one occasion to withdraw some of them from the market.
But what is new is that researchers from Russia have developed a new type of battery technology, which they say can charge about 10 times faster than current lithium batteries.
The researchers hope that this acceleration will provide enormous benefits, most notably in terms of time it takes to recharge mobile devices.
“A battery manufactured using polymer will be charged in seconds, which is about 10 times faster than a conventional lithium battery,” says researcher in electrochemistry, Oleg Levin, from the University of St. Petersburg in Russia.
Levin emphasized that this has already been proven through a series of experiments.
The idea of the new battery is based on a type of redox polymer based on nitroxyl, a substance that can undergo reverse oxidation (loss of electrons) and reduction (gain of electrons) when discharged and charged.
“In nitroxyl-dependent polymers, the only charge transfer pathway is to move between neighboring redox centers, which is fast at the microscopic level,” the researchers explain in their study.
The new battery also performs well in lower temperatures, which is unavailable for heat-sensitive lithium batteries.
