A solid electrolyte could not only increase battery life, but also storage capacity and safety, as liquid electrolytes are the leading cause of battery fires.
Lithium ion batteries use a liquid electrolyte which is an organic solvent that has been responsible for overheating and fires in cars, commercial airliners and mobiles.
With a solid electrolyte you could throw it against the wall, drive a nail through it — there’s nothing there to burn.
Gerbrand Ceder, a professor of materials science and engineering at MIT said that there’s virtually no degradation, meaning such batteries could last through hundreds of thousands of charges.
The researchers, who published their findings in the peer-reviewed journal Nature Materials, described the solid-state electrolytes as an improvement over today’s lithium-ion batteries.
A battery’s electrolyte component separates the battery’s positive cathode and negative anode terminals, and it allows the flow of ions between terminals. A chemical reaction takes place between the two terminals producing an electric current.
The idea of solid electrolytes has been around for a while. The problem was that they could not conduct ions fast enough to be efficient energy producers.
The MIT team says it overcame that problem which is why its boffins have nice creases on their white lab coats.
Solid-state lithium-ion battery is that it can perform under frigid temperatures which is more than most scientists.
