Researchers suggest approach for boosting Li-S performance; conversion of Li2S to sulfur without polysulfides

Green Car Congress

Lithium-sulfur batteries are one of the most promising alternatives for next-generation high-energy-density batteries; however, one of the main obstacles to widespread commercialization that still needs to be addressed is the polysulfide shuttle mechanism between the two electrodes. earlier post.). the “ionic wiring”. 2017.01.112.

Researchers Develop Novel High-Performance Polymer Tin Sulfur Lithium Ion Battery

Green Car Congress

Sketch of the Sn/C/CGPE/ Li 2 S/C polymer battery. The battery is formed by a Sn/C composite anode, a PEO-based gel polymer electrolyte, and a Li 2 S/C cathode. Lithium-sulfur cells are based on the electrochemical reaction: 16Li + S 8 8Li 2 S. PEO=poly(ethylene oxide). Credit: Hassoun and Scrosati. Click to enlarge.

Inaugural Quadrennial Technology Review report concludes DOE is underinvested in transport; greatest efforts to go to electrification

Green Car Congress

There is significant headroom for DOE to work on increasing conventional vehicle efficiency by improving the internal combustion engine, by lightweighting, and by improving the aerodynamics of heavy-duty vehicles. Near-term improvements will likely be the result of improved lithium-ion batteries. Alternative hydrocarbon fuels.
