LIC -G C
Ohara has developed a high performance
fast lithium-ion conducting glass-ceramic.
The LIC-GC material has excellent chemical
resistance and can be supplied in powder,
solid plates, or flexible sheet.The unique
properties of LIC-GC make it suitable for
use as an electrolyte or separator in next
generation lithium batteries, gas sensors
and other electrochemical devices.
ADVANTAG E S
High L ithium-Ion C onduc tivity: The LIC-GC lithium-ion conductivity
is higher than 10 -1 S/m (=10 -3 S/cm) at room temperature. This value
is one of the highest ion conductivity values for a solid electrolyte.
LIC-GC's ionic conductivity obeys Arrhenius-type equations.
Outs tanding C hemic al P roperties : LIC-GC glass-ceramic has excellent
chemical resistance. Water/moisture and acid have minimal influence
on the lithium-ion conductivity.
