On February 28th 2017, researchers at the University of Texas at Austin announced that they had created a solid state rechargeable battery that could replace those made with lithium. The team was led by John Goodenough, who is one of the co creators of the lithium ion battery, which is currently used in most portable devices such as cell phones and laptops. Goodenough says that the new solid state battery can charge in minutes instead of hours and will not explode.
The reason that the new solid state battery is better than the lithium ion battery is because it doesn't use a liquid. Instead the solid state battery uses glass electrolytes, which is a chemical structure that can allow electricity to pass between a positive and a negative electrode. This gives the new battery a density that is three times greater than a lithium ion battery, and allows it to perform better at low temperatures.
Tests of the solid state battery revealed that it can be charged and run down for over 1,200 cycles with low cell resistance. The battery has also proven to operate at -4 degrees Fahrenheit, which would make it an ideal choice for some automobiles. And, the solid state battery uses sodium as opposed to lithium, which also makes the solid state battery very cost effective
