Silica-based cathode enables long-life Li-S batteries

Green Car Congress

Lithium–sulfur batteries—composed of a sulfur-based cathode and lithium anode submerged in a liquid electrolyte—are promising candidates to replace the ubiquitous lithium-ion battery because of their low cost and the non-toxicity and abundance of sulfur. However, carbon-based hosts cannot trap LiPS.

Japanese start-up seeks to commercialize dual-carbon battery technology; anion intercalation

Green Car Congress

Start-up Power Japan Plus announced plans to commercialize a dual-carbon battery technology, which it calls the Ryden dual carbon battery. Dual-carbon (also called dual-graphite) batteries were first introduced by McCullough and his colleagues at Dow Chemical in a 1989 patent, and were subsequently studied by Carlin et al.

China team reports high-rate, high-capacity, long lifecycle Li-sulfur cell using nitrogen-doped graphene cathode material

Green Car Congress

The cells also exhibited an ultralong cycle life exceeding 2000 cycles and an extremely low capacity-decay rate (0.028% per cycle)—among the best performance demonstrated so far for Li/S cells, according to the researchers. The achieved best performance for earlier nitrogen-doped graphene-S nanocomposites was about 671 mA h g ?
