Lyten’s lithium-sulfur batteries could cut both weight and cost—if they can last. Lyten uses a 3D graphene material to boost the energy density of their lithium-sulfur batteries. Lyten The key to building less-expensive batteries that could extend the range of EVs might lie in a cheap, abundant material: sulfur.
But a lower cost of materials means the potential for cheaper batteries in the future. Not only could lithium-sulfur batteries eventually provide a cheaper way to store energy—they could also beat out lithium-ion on a crucial metric: energy density.
As stated previously, Li-S batteries could potentially have a significant advantage over LIB in light of low cost of sulfur. However, the high cost and sophisticated synthesis process of carbon/noncarbon hosts in most investigations offset this advantage.
Attaining jointly high energy density at low cost is extremely challenging for lithium-sulfur (Li-S) batteries to compete with commercially available Li ion batteries (LIB).
That’s because taming the chemical reactions that power lithium-sulfur batteries has proved to be a challenge. Unwanted reactions between lithium and sulfur can sap the life out of batteries and drive them to an early grave.
The lithium–sulfur battery (Li–S battery) is a type of rechargeable battery. It is notable for its high specific energy. The low atomic weight of lithium and moderate atomic weight of sulfur means that Li–S batteries are relatively light (about the density of water).
