This past decade has seen extensive research in lithium-sulfur batteries with exemplary works mitigating the notorious polysulfide shuttling. However, these works utilize ether electrolytes that are highly volatile severely hindering their practicality. Here, we stabilize a rare monoclinic γ-sulfur phase within carbon nanofibers that enables successful operation of Lithium-Sulfur (Li-S) batteries in carbonate electrolyte for 4000 cycles. Carbonates are known to adversely react with the…

A highly efficient polysulfide mediator for lithium-sulfur batteries.

A strategy to entrap polysulfides in the cathode that relies on a chemical process, whereby a host--manganese dioxide nanosheets serve as the prototype--reacts with initially formed lithium polysolfides to form surface-bound intermediates, which are among the best reported to date.

Enhanced Performance of a Lithium-Sulfur Battery Using a Carbonate-Based Electrolyte.

A novel electrolyte is designed not only to address the above problems of Li anode but also to match sulfur cathode perfectly, leading to extraordinary electrochemical performances.

It is shown that the problem of sulfur loss can be effectively diminished by controlling the sulfur as smaller allotropes in the confined space of a conductive microporous carbon matrix.

Single step transformation of sulphur to Li2S2/Li2S in Li-S batteries

A practical approach is realized towards a direct transformation of sulphur to Li2S2/Li2S in lithium-sulphur batteries by alteration of the reaction pathway by using a coconut shell derived ultramicroporous carbon-sULphur composite cathode as reaction directing template.

The effect of a solid electrolyte interphase on the mechanism of operation of lithium–sulfur batteries

Composite sulfur–carbon electrodes were prepared by encapsulating sulfur into the micropores of highly disordered microporous carbon with micrometer-sized particles. The galvanostatic cycling

On the Surface Chemical Aspects of Very High Energy Density, Rechargeable Li–Sulfur Batteries

Li(metal)-sulfur (Li-S) systems are among the rechargeable batteries of the highest possible energy density due to the high capacity of both electrodes. The surface chemistry developed on Li
