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.

Features & Benefits

Product Features & Benefits

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.

  • Conducts lithium ions at room temp
  • Forms composite membranes with inorganic solid electrolyte particles
  • Flexible membrane can be cast
  • H-polymer readily dissolves in common organic solvents such as acetonitrile
  • As a conductive binder, H-polymer can replace part of the PVDF binder and is soluble in NMP.

H-polymer is available in lots of 10g, 25g, 50g, 100g, 250g, 500g – up to kilogram quantities.
