Solid state batteries have just been invented, and they should be cheaper, safer and specifically longer-lasting than current types – and we’re hoping we’re going to get them… soon.
Want to speed up your computer – one of the main advices is to buy a solid-state drive (SSD) instead of the traditional HDD. The same might be in order in the future for electric cars. This is because a team of engineers, led by 94-year-old professor John Goodenough from the Cockrell School of Engineering at The University of Texas at Austin, has been working on a project involving solid-state batteries. You might not have heard of the man – but he’s actually responsible (at least in part) for every single mobile device’s prolonged life. This is because he is the co-inventor of the lithium-ion batteries… which are also widely used today in electric cars.
Even at that advanced age, he still searched for a breakthrough, and apparently found it in solid-state batteries. A thesis published in the journal Energy and Environmental Science demonstrates a new type of battery that has at least three times as much energy density as today’s lithium-ion batteries. They are also longer in terms of cycle life and have fast rates of charge and discharge. They can also operate very well in cold weather, up to -76 degrees Fahrenheit (-60 degrees Celsius). “Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today’s batteries,” said Goodenough.
