| This glass-ceramic material is fast, Lithium-ionic conducting solid electrolyte. By applying OHARA's manufacturing technology for accumulating optical glass and glass-ceramics, lithium-ionic conducting glass-ceramic with superior performance was achieved. This glass-ceramic has good chemical resistance, and again, is suitable for various solid electrolytes, since it has practical ionic conductivity. |

Advantages
High Lithium-ionic Conductivity:
Lithium-ionic conductivity is higher than 10-1S.m-1(10-3S.m-1) at the room temperature. This value is one of highest conductivity for a solid electrolyte. The ionic conductivity obey on Arrhernius-type equation. (See figure)
Prominent Chemical Properties:
This glass-ceramics has good chemical resistance. In addition, Lithium-ionic conductivity is not influence against water and acid.
