Breakthrough for electrification
SuperBattery is an innovative technology combining supercapacitor and battery characteristics. It can be charged 100x faster than lithium-ion batteries, has 50,000 life cycles, and is free from cobalt, copper, and nickel. It is also much safer than li-ion batteries, even when crushed, pierced, or overheated.
