New electrolyte makes lithium-sulfur batteries safe and durable

Otis Energy has developed a stable and durable lithium-sulfur battery, the container of which is twice as much as existing lithium-ion.

Lithium-sulfur batteries exist since the 1960s and are well known for their high energy density and low cost. Their main disadvantage is that lithium polysulfides are well dissolved in the electrolytes used, which is why the cathode is quickly melted.

Researchers from Otis Energy argue that they have developed a safe non-flammable electrolyte that retains metal lithium much longer. This prolongs the battery life of up to 250 charging / discharge cycles, and within two years, engineers plan to increase this indicator to 500 cycles, which is the average level of modern lithium-ion batteries.

In addition, the team used in its design a lithium ceramic lithium sulphide, which blocks electricity streams preventing overheating, sudden discharge and gradual energy leakage during downtime.

The created battery has the energy intensity of more than 500 VTC / kg, which is much better than that of modern commercial lithium-ion batteries.

Otis Energy has already signed a contract with the Aviation Company by Aerospace, which will use the developed lithium-sulfur batteries in their small electrons. According to the designers, this will increase the range of flights by 50-100%, by reducing the mass of energy accuracy.

If the project is successful, the company will consider the prospects for electrifying aircraft for regional transport.

Due to the limited lithium reserves, researchers around the world are searching for effective alternatives from more common elements, and recently developed high-power potassium batteries in Skoletech,
