Zeta’s sulfurized-carbon cathode

The obstacle that has held lithium-sulfur back for decades is the polysulfide shuttle effect. Soluble sulfur compounds migrate through the electrolyte, degrading capacity and preventing the cell from delivering good power.

Zeta’s patented sulfurized-carbon cathode stops this at the source. We chemically bond the sulfur to a carbon host and trap it in place, so it cannot migrate. The result is a cathode that delivers high capacity, stable cycling, and real power.
