Samsung has created a survivable battery for electric cars for 800 kmMarch 16, 2020
Samsung has created a solid state battery for electric vehicles that could revolutionize the world of green vehicles. The most important advantages of this battery are durability and long-range.
The new battery (so far only a prototype is ready) was developed by two divisions of the South Korean techno-giant – Samsung Advanced Institute of Technology (SAIT) and Samsung R&D Institute Japan (SRJ). The creators note that their development is able to withstand more than 1000 charge cycles, and the mileage on one charge, which it can provide, is 800 km.
In addition, such a battery is more compact (due to its higher density) and safer than modern lithium-ion batteries using liquid electrolytes.
To achieve the above features, engineers focused on overcoming the problem of dendrites – needle-like crystals that can form on the anode of a solid-state battery during charging and, thus, reduce its battery life and adversely affect safety. To do this, they made a new anode – from a composite material based on silver and carbon.
Researchers note that a ball of silver and carbon allowed, among other things, to increase the energy density up to 900 Wh / l (2-2.5 times in comparison with lithium-ion batteries).
Samsung hopes that their solution will help stimulate the development of electric cars, however, it’s hard to say when the new battery will appear on production cars (and whether it will appear at all).
