lithium-sulfur battery

Brisbane-based Li-S Energy has developed a 20-layer battery cell utilizing semi-solid state lithium sulfur battery technology. The company claims the new cell displays nearly double the gravimetric energy density and a comparable volumetric energy density to lithium-ion cells.

Edinburgh-based energy storage solutions specialist StorTera has developed a long-duration, energy-dense, lithium-sulfur-based single liquid flow battery (SLIQ). The tech is said to last for 30 years with minimal degradation.

Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

Oxfordshire-based Oxis Energy says it will produce the less flammable devices sought by the aviation industry using the same manufacturing processes as those used to make lithium-ion and conventional-lithium-sulfur products.

The Korea Aerospace Research Institute has conducted a battery-powered test flight of solar-powered unmanned aerial vehicle EAV-3. The aircraft is powered by solar cells on its wings and body and an LG Chem lithium-sulfur battery.

British Li-S cell manufacturer Oxis Energy today revealed it is working with U.S. planemaker Texas Aircraft Manufacturing on a pilot training and private transport aircraft. The trainer appears likely to be at least three years away from development, given the commissioning timeline previously announced for Oxis’ Brazilian cell factory.
