Conductive PEDOT:PSS Aqueous Dispersion as Battery Electrode Binder, 100 g/bottle, CBEBPEDOTPSS

PEDOT:PSS is a complex of two polymers with opposite roles: (1) The "backbone" of PEDOT It is a conjugated polymer that provides the high electronic conductivity. It is naturally insoluble. (2) The "stabilizer." of PSS is a water-soluble polyelectrolyte that carries negative charges. It balances the charge of PEDOT, allowing it to stay dispersed in water as a stable colloidal solution. The oxygen atoms in the PSS chain form strong hydrogen and covalent bonds with the native SiO2 layer on silicon nanoparticles. This "chemical glue" prevents silicon from detaching and becoming "dead" during cycling. Moreover, the abundant oxygen and sulfur atoms in the PEDOT:PSS binder effectively chemisorb lithium polysulfides, physically and chemically blocking the "shuttle effect" in Li-S battery.
