The new battery tech is not only eco-friendly, it is more cost effective and offers superior performance too.
Even at 94, John B. Goodenough, a professor at the University of Texas, isn’t done with changing the landscape of today’s battery technology.
The Austin-based professor who has widely been credited for the invention of lithium-ion batteries has developed a superior alternative. Maria Helena Braga, a senior researcher at Cockrell School along with Goodenough and team have created a new kind of solid state battery that is not only superior than lithium-ion but also safer and most importantly it is also cheaper.
The new battery stores three times as much energy than the current lithium-ion batteries, which means the mileage for electric vehicles are likely to jump significantly, thus EVs will cover more miles between charges.
Also when you need to charge it, instead of the charging times being in hours, it can be done in minutes. Further, the new batteries have higher discharge rates and charging numbers.
Since the new technology replaces the liquid by glass electrolytes in lithium-ion batteries, this replacement means that the new batteries will not suffer from dendrites.
Dendrytes are the primary reason lithium-ion batteries tend to short circuit, catch fire and even explode.
The glass electrolytes have also another benefit, these batteries can operate in temperatures upto -4 degrees Fahrenheit (-20 degrees Celsius).
Since the new batteries use low cost sodium, they are eco-friendly too.
Goodenough and his team are now looking to collaborate with battery manufacturers so that their creation can be tested in EVs and in other energy storage devices.
