According to Futurism, John Goodenough, the co-inventor of the lithium ion battery, and a team of engineers have developed the first all-solid-state battery cells. These longer lasting batteries can lead to safer and faster- charging devices for mobile devices, electric cars, and energy storage.
Goodenough stated, “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.”
In a recent paper published by Energy and Environmental Science, this revolutionary battery will have low costs and are designed to be noncombustible. These all-solid-state batteries have a higher energy density and faster charging times opposed to traditional batteries. These units are made completely with earth friendly materials.
Current lithium ion batteries liquid electrolytes to transfer lithium ions between the negative and positive sides of the battery. The problem is that if the battery is charged too rapidly, it can cause dendrites and cross through the liquid electrolytes, which would ultimately lead to short circuit fires or explosions. All-solid-state batteries use glass electrolytes rather than liquid and prevent the developments of dendrites.
Furthermore, since the solid-glass electrolytes are capable of operating at -20 degrees celcius, which makes the all-solid-state technology be the first to allow the battery functionality in subzero temperatures. Tests have shown that these innovative batteries can withstand over 1,200 cycles.
Cockrell School senior researcher Maria Helena Brag commented, “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,”
