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

NANOMYTE® H-polymer is composed of a proprietary PEO-based co-polymer with Lithium Salt added. The material can be handled in a dry room for short periods of time, but it is important that the material not be exposed to moisture at any time.
Precautions for Safe Handling
Appropriate personal protective equipment should be used at all times. Avoid contact with eyes and skin. Toxic if swallowed or contact with skin. Provide good ventilation or extraction, and avoid breathing vapors. Avoid formation of dust.
Conditions for Safe Storage
Keep container tightly closed in a dry and well-ventilated place. Storage class (TRGS 510): Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effects.
