Ukrainian specialists created a lithium-sulfur rechargeable battery featuring higher cycling stability, Speka reports, citing dev.ua.

The battery was developed by maxAh, a start-up company. It is based on Ukrainian-made graphene and is intended as a power source for gadgets.

The developers have already shown a prototype of a new lithium-sulfur (Li-S) battery. It is fully functional and demonstrates the stability of charge/discharge cycles. The company claims that the novelty’s cycling stability is several times higher compared to batteries based on a conventional electrolyte, which causes rapid solution of sulfur.

During the creation of the battery, Ukrainian-made manganese oxide and graphene were used.

The novelty has three times the capacity, works three times longer, and its cost is predicted to be lower than that of lithium-ion batteries. In addition, the developers claim that the probability of overheating of the battery is 500% lower than that of most existing analogs on the battery market.

maxAh has opened an additional investment round to create a state-of-the-art laboratory that will allow for the improvement of existing prototypes, scaling up the development and speeding up their commercialization.
