The carbon/sulfur composite cathodes of lithium sulfur batteries undergo mesostructural evolutions during discharge due to the dissolution/precipitation reactions of solid sulfur and Li2S. Furthermore, the cathode design ...

The interaction of polysulfides with graphene layers substitutionally modified with heteroatoms is analyzed using first-principles calculations, with the aim of using these structures to prevent polysulfide migration in ...

Since the resurgence of interest in lithium-sulfur (Li-S) batteries at the end of the 2000s, research in the field has grown rapidly. Li-S batteries hold great promise as the upcoming post-lithium-ion batteries owing to ...

Manganese, zinc and mixed manganese-zinc oxides were synthesized after a biohydrometallurgical process to recycle alkaline and Zn/C batteries. A mixture of alkaline and Zn/C batteries was leached with biogenerated sulfuric ...

Lithium-sulfur batteries are presented as a promising alternative for the operation of those devices, including electric vehicles,that require higher specific capacity than current lithium-ion technology. Unfortunately, ...

La transición energética es indispensable para la continuidad de los sistemas sociales y ecológicos. La crisis climática es, en esencia, una crisis energética. Para la aplicación práctica de fuentes renovables de energía ...

Lithium-ion batteries have enabled electric vehicles to achieve a foothold in the automobile market. Due to an increasing environmental consciousness, electric vehicles are expected to take a larger portion of the market, ...

In this research, the shuttle effect and the low sulfur activation of lithium–sulfur batteries were mitigated by coating the cathode side of Celgard 2400 separators with mixtures of carbon black/chitosan or carbon ...
