Sulfur–TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

Researchers at Stanford University and SLAC led by Stanford associate professor Yi Cui have used a sulfur–TiO 2 yolk–shell design for a cathode material for a lithium-sulfur battery that achieved an initial specific capacity of 1,030?mAh?g This is the highest performing sulfur cathode in the world, as far as we know.

Li-ion sulfur polymer battery shows high energy density as well as safety

Green Car Congress

A team from the University of Rome Sapienza has developed a rechargeable lithium-ion polymer battery based on the combination of a high capacity sulfur-carbon cathode, nanostructured Li x Sn-C anode and polysulfide-added PEO-based gel membrane. Batteries Li-Sulfur' Moreover, the addition of a dissolved polysulfide (i.e.
