...AND CHEAPER...:

IBM Research Created a New Battery That Outperforms Lithium-Ion--No Problematic Heavy Metals Required (Andrew Liszewski, 12/19/19, Gizmodo)

IBM Research's Battery Lab came up with a new design that replaces the need for cobalt and nickel in the cathode, and also uses a new liquid electrolyte (the material in a battery that helps ions move from one end to the other) with a high flash point. The combination of the new cathode and the electrolyte materials was also found to limit the creation of lithium dendrites which are spiky structures that often develop in lithium-ion batteries that can lead to short circuits. So not only would this new battery have less of an impact on the environment to manufacture, but it would also be considerably safer to use, with a drastically reduced risk of fire or explosions.

But the benefits of IBM Research's design don't stop there. The researchers believe the new battery would have a larger capacity than existing lithium-ion batteries, could potentially charge to about 80 percent of its full capacity in just five minutes, would be more energy-efficient, and, on top of it all, it would be cheaper to manufacture which in turn means they could help reduce the cost of gadgets and electric vehicles.
