Hong Kong researchers propose novel cathode design for Li-S batteries

A team led by Professor Zhao Tianshou of the Hong Kong University of Science and Technology has proposed a novel cathode design concept for lithium-sulfur (Li-S) batteries. Li-S batteries are regarded as attractive alternatives to Li-ion batteries. They are known for their high energy density, while their major component, sulfur, is abundant, light, cheap and… Read more »

Oxis Energy’s ultralight Li-sulfur batteries are aimed at aviation

Oxfordshire-based Oxis Energy has been working on lithium-sulfur battery technology since 2004 (Charged has reported on the company several times over the years). In a recent article in  IEEE Spectrum, the company’s Head of Battery Development and Integration, Mark Crittenden, explains why lithium-sulfur tech is uniquely suited to electric aviation. Weight is a critical constraint… Read more »

OXIS Energy and Mercedes to build Li-S plant in Brazil

OXIS Energy and the Minas Gerais Development Company have signed a 15-year lease agreement with Mercedes Benz Brazil (MBB) to take possession of a plant located at the MBB manufacturing site in Juiz de Fora in southeast Brazil, to produce lithium-sulfur battery cells.

Promising lithium-sulfur active battery material made with low-cost liquid phase process

Scientists at the Toyohashi University of Technology have made an active sulfur material and carbon nanofiber (CNF) composite using a low-cost liquid phase process. Their paper, published in the American Chemical Society’s ACS Applied Energy Materials, claims that all-solid-state lithium-sulfur batteries using a sulfur-CNF composite material show higher discharge capacity and better cycle stability than… Read more »

OXIS says its lithium-sulfur battery is close to achieving 500 Wh/kg

OXIS Energy has successfully tested its lithium-sulfur (Li-S) battery cell prototypes at 471 Wh/kg. The company said it expects to achieve 500 Wh/kg in the next 12 months. OXIS research scientists think they can extend both gravimetric and volumetric energy density towards 600 Wh/kg and over 800 Wh/L. OXIS has also developed a standard Li-S battery… Read more »

IBM and Daimler claim quantum leap in lithium-sulfur battery breakthrough

Electric vehicles may be the wave of the future, but each machine is only as good as its battery. A breakthrough in quantum computing from a Daimler-IBM collaboration may change the way we think about the power of lithium. Researchers are one step closer to creating cheaper, more powerful, longer lasting batteries accessible to a… Read more »
