While not an excellent conductor of electricity, graphene oxide has sufficient conductivity to anchor the sulfur to the cathode, thereby permitting a large flow of current to pass through the ...

With the merits of rGO such as good conductivity and flexible structure, the nanocomposite of EDA-functionalized rGO and sulphur (denoted as EFG–S) exhibits exceptionally stable capacity ...

From head-to-tail to side-by-side, the quasi-1D copper-sulfur lattice may have got much stronger inter-chain interaction to activate tunneling in between. This explains the huge improvement of ...

Yet, despite their potential, LSBs face key challenges, including poor conductivity, severe volume expansion, and the “shuttle effect.” Insulative sulfur intermediates, such as Li 2 S 2 and Li ...

"Lithium-sulfur is one such novel rechargeable battery ... that we have to find a material with both sufficient electrical conductivity and surface polarity. Titanium carbide is the 'chosen ...

The researchers overcame these barriers by building a solid electrolyte made of lithium polysulfidophosphates (a new class of sulfur-rich materials with good electrical conductivity) to create an ...

Some advantages include easy manufacturing, high conductivity, and a robust structure that all improve the function of the lithium-sulfur batteries. Current lithium-ion battery technology does not ...

By inserting iodine molecules into the crystalline sulfur structure, the researchers drastically increased the cathode material's electrical conductivity by 11 orders of magnitude, making it 100 ...

Their result is a crystalline sulfur cathode, with iodine molecules inserted into the crystal structure. Performance testing found that the addition of these iodine molecules enhanced the cathode’s ...

There are materials that can store even more lithium than silicon; a notable example is sulfur. But sulfur has a tendency to react with itself, producing ions that can float off into the electrolyte.
