Li-ion Battery Inventor has New Tech for Fast-Charging Noncombustible Batteries

This guy is responsible for one of the most commonly used types of battery ever, so I will go ahead and give him the benefit of the doubt that this won’t be another could-be battery revolution that merely fizzles out. John Goodenough, at 94 years old, has developed new all-solid-state battery cells that last longer and do not pose explosive risks. The increased energy density would also do wonders for electric vehicles and how long they could go between charges.

The use of an alkali-metal anode (lithium, sodium or potassium) آ— which isn’t possible with conventional batteries آ— increases the energy density of a cathode and delivers a long cycle life. In experiments, the researchers’ cells have demonstrated more than 1,200 cycles with low cell resistance. Additionally, because the solid-glass electrolytes can operate, or have high conductivity, at -20 degrees Celsius, this type of battery in a car could perform well in subzero degree weather. This is the first all-solid-state battery cell that can operate under 60 degree Celsius.
