Mechanistic modeling of polysulfide shuttle and capacity loss in lithium-sulfur batteries

06/02/2014 12:32:16
Lithium-sulfur (Li/S) cells are promising candidates for a next generation of safe and cost-effective high energy density batteries for mobile and stationary applications. At present, Li/S cells still suffer from poor cyclability, capacity loss under moderate current densities and self-discharge. Furthermore, the underlying chemical mechanisms of the general discharge/charge be... continua »

Mastering the challenges of sulfur-based lithium secondary batteries – A review

24/09/2013 17:38:14
This review is an attempt to report the latest development on the lithium-sulfur battery, namely the storage system that, due to its potential energy content, is presently attracting considerable attention both for automotive and stationary storage applications. We show here that consistent progress has been achieved, to the point that this battery is now considered to be near to industrial produc... continua »

Composite Poly(ethylene oxide) Electrolytes Plasticized by N-Alkyl-N-butylpyrrolidinium Bis(trifluoromethanesulfonyl) imide for Lithium Batterie

08/11/2012 16:14:20
In this work we report a new class of quaternary polymer electrolyte membranes comprising poly(ethylene oxide), PEO, lithium trifluoromethanesulfonylimide, LiTFSI, salt, N-alkyl-N-butyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide, PyrA,4TFSI, ionic liquid, and SiO2-filler. Results of differential scanning calorimetry indicate that the addition of SiO2-filler induces a reduction of the PEO mel... continua »
