lithium-sulfur

Lithium-sulfur battery technology company Oxis Energy has hired Scott Davis to manage cell production at its new manufacturing plant in Wales.

Davis will manage the Oxford-based firm’s new facility at Kenfig Hill near Port Talbot, which is due to start producing cathode and electrolyte to support the production of 500,000 lithium-sulfur cells next year.

Scientists at the Dalian Institute of Chemical Physics (DICP) at the Chinese Academy of Sciences have developed a cathode they claim will increase the performance capabilities of lithium-sulfur batteries.

Teams led by professor Jian Liu (pictured) and professor Zhongshuai Wu have increased the catalytic activity and sulfur loading of lithium-sulfur batteries by using a mesoporous carbon nanoreactor decorated with Fe1-xS electrocatalyst nanoparticles (Fe1-xS-NC) as the cathode. 

Researchers at IBM and vehicle OEM Daimler have used a quantum computer to help them design next-generation lithium-sulfur batteries.

Scientists used quantum hardware to calculate the dipole moment of three lithium-containing molecules for lithium hydride (LiH) using four qubits— a basic unit of quantum information— on IBM’s Q Valencia quantum computer.

Scientists from Singapore-based NanoBio Lab (NBL) have developed a means of making lithium-sulfur cathodes that increase specific energy and curbs capacity fade. 

The team began by building the carbon host before adding the sulfur source to obtain a 3D interconnected porous nanomaterial.
