tired of your smartphone battery dying? the solution could be on its way - lithium ion rechargeable battery

Thanks to MIT researchers, longer-lasting smartphones are on the way.
Source: Researchers at the famous Massachusetts Institute of Technology in the United States have discovered the secret of doubling the battery life of smartphones (MIT).
A group of former students working under SolidEnergy Systems are planning to commercialize a new battery that they say will help users avoid the dreaded black screen for longer.
The secret, they say, is a rechargeable lithium-metal battery that will soon replace the traditional lithium-ion batteries used in most smartphones.
MIT alumni Qichao Hu explained the breakthrough to the MIT news website. “With two-
"The energy density is twice that of a lithium-ion battery, and we can make half the size of the battery, but it still lasts the same amount of time," he said . ".
"Or we can make a battery of the same size as a lithium-ion battery, but now it will have twice the life of a lithium-ion battery. . .
This is the holy grail of batteries.
The secret is simple, but the science is very complicated.
Source: The supplied lithium metal has been tested before, but there are also some problems, including safety issues.
The researchers have previously found that the occurrence of shoot-Crystal or small metal bumps has begun, resulting in short circuit and overheating.
The developer uses "ultra-thin metal lithium foil. . . about one-
According to the MIT News, the fifth is the thickness of the traditional lithium metal.
They then coat the foil with a thin solid electrolyte that prevents overheating.
The new battery is in the development phase, in part because of the accelerator competition for the $100,000 startup competition for its creators and the $12 million investment.
So, when can you get one?
The company said that as early as 2017 of smartphone manufacturers, from there to electric car manufacturers, can buy Solid Energy batteries.
Look at this space.
