Lithium-Ion Conducting Glass-Ceramics (LICGC™)

Glass-ceramic that enables advanced lithium metal cells and serves as a true solid-state electrolyte or separator in next generation lithium-ion battery electrolytes and other electrochemical devices.  


High Lithium-Ion Conductivity:

1 to 4 x 10 -4 S/cm at room temperature. These are some of the highest conductivity values achieved in a solid electrolyte. Lithium-ion transport # is 1.

Outstanding Chemical Properties:

LICGC™ has excellent chemical resistance. Water and mild acid have minimal influence on the lithium-ion conductivity.

Excellent Physical and Mechanical Properties

  • Stable in air & water
  • True solid electrolyte
  • Non-flammable
  • Safe, prevents dendrite penetration
  • Supplied in various sizes

Lithium-Ion Conductivity:

1 x 10 -4 S/cm at 25°C for LICGC™ (AG-01) Membranes
