Solid State Battery from the Man Who Brought Us Lithium Ion

Who is [John Goodenough]? He’s 94, so he’s been around long enough that you ought to know him. He was one of the co-inventors of the lithium-ion battery. Think about how much that battery has changed electronics. [Goodenough] along with [Maria Helena Braga] may have come up with that battery’s successor: the solid state battery. There’s a paper available that is free, but requires registration. If you don’t want to register, you can read the news release from the University of Texas with no trouble.

Keywords used to describe the new battery are low-cost, noncombustible, long cycle life, high energy density, and fast charge and discharge rates. The pair is also claiming three times the energy density of a current lithium-ion battery. They also claim that the batteries recharge in minutes instead of hours. You can see a video from [Transport Evolved] that discusses the invention, below.

Could Solid-State Batteries Last a Lifetime?

Researchers from MIT and the Samsung Advanced Institute of Technology have been developing a new material that could potentially revolutionize the battery industry. A solid electrolyte that won’t wear out, lasting exponentially longer than current battery chemistry.

It also has the possibility to increase battery life, storage, and the safety of batteries — as liquid electrolytes are the main reason batteries catch on fire.

Sound too good to be true? The idea for solid-state batteries has been around for awhile, but it sounds like MIT and Samsung may have figured it out. The current materials used for solid electrolytes have difficulty conducting ions fast enough in order to be useful — but according to the researchers, they’ve discovered formula for the secret sauce. They’ve published their findings on Nature.com, which is sadly behind a pay wall.

Another great benefit of solid-state batteries is they would be able to operate at freezing temperatures without a problem. What do you think? Is Samsung blowing smoke, or will they actually release a battery you never have to replace?
