Due to the higher power density, the battery could become a real alternative to previous lithium-ion batteries. Initial tests are already expected to prove a 3-fold performance compared to lithium-ion batteries. In addition, the batteries are lighter and more environmentally friendly

to manufacture.
Until now, this type of battery was not stable enough for frequent loading and unloading.

The Australian researchers have now found a methide that solves this problem.

In the lithium-sulfur cell, a sulfurcathode is used instead of the nickel-cobalt cathode. This expands when the lithium is absorbed and contracts again when it is released. This leads to microcracks in the material. The resulting decrease in performance of the lithium-sulphur battery has been a major problem until now.

Researchers from Australia have now developed a method that considerably stabilizes the battery. To do this, the sulfur cathode is surrounded by a layer of a binder and carbon. The binder consists of sodium carboxymethyl celluloses (Na-CMC).

However, the lithium-sulfur battery is larger than the lithium-ion battery.

Imagine driving an electric car, which has a range of up to 1000 km, writes the Monash University in an article on their website.


Big plus points are
  • the more environmentally friendly manufacturing process,
  • the low cost of production and
  • the higher performance of the battery.Translated with www.DeepL.com/Translator (free version)
