Solid Polymer Electrolyte

NANOMYTE® H-polymer is a solid polymer electrolyte specifically designed for lithium-ion battery applications. As a 100% solid material, H-polymer combines the benefits of high room temperature ionic conductivity with the good mechanical properties of a solid polymer.

H-polymer is a PEO-based copolymer with PEO segments in the polymer backbone. PEO has been intensively explored as a solid polymer electrolyte. Although the PEO / lithium salt complex has good lithium-ion conductivity above 60 °C, the room temperature ionic conductivity is typically low due to the crystallization of PEO chains. NANOMYTE® H-polymer overcomes this drawback by having an amorphous structure and a much improved ionic conductivity of around four orders of magnitude higher (~ 5 x 10-5 S/cm) than that of pure PEO.

NANOMYTE® H-Polymer can be used as a separator, by itself, or in combination with an inorganic solid electrolyte. It can also be used as a Li-ion conductive binder to reduce the interfacial resistance between cathode or anode particles.
