Solid Polymer Electrolyte
NANOMYTE® H-polymer
NANOMYTE® H-polymer is a solid polymer electrolyte engineered for advanced lithium-ion battery applications. As a 100% solid-state material, H-polymer uniquely integrates high room-temperature ionic conductivity with robust mechanical integrity, addressing critical challenges in solid-state battery design.
This innovative material is a poly(ethylene oxide)-based copolymer, where PEO segments are strategically incorporated into the polymer backbone. While PEO/lithium salt complexes have been widely investigated for their lithium-ion conductivity above 60 °C, their practical room-temperature performance has been limited by the inherent crystallization of PEO chains. NANOMYTE® H-polymer effectively mitigates this drawback through its amorphous structural design, yielding a significantly enhanced ionic conductivity. This results in an ionic conductivity approximately four orders of magnitude higher than that of pure PEO, reaching values around 5×10−5 S/cm at room temperature.
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.
