Poly(ethylene oxide, PEO ) Powder for Li-Metal Battery, 250 g/Bag - EQ-Lib-PEO

oly(ethylene oxide) ( PEO) is a water-soluble polymer. Although PEO does not have a good ionic conductivity (around 10^-4 - 10^-8), it is widely used in conjunction with carbon black or conductive ceramic powder to form a conductive composite, and also can be used to make solid electrolyte for Li-Metal battery.
