Materials for Next-generation

Lithium ion battery

Oxide based Solid Electrolyte

LLZO doped with Mg and Sr

Niterra is developing materials for Next-generation Lithium ion batteries by taking advantage of the "High safety of ceramics" and "Niterra's material development capabilities".
We have succeeded in developing an oxide solid electrolyte with top-class ionic conductivity.

Advantages of Niterra's Solid Electrolyte

World's top class
High ionic conductivity

While the ionic conductivity (at room temperature) of oxide solid electrolytes generally ranges from 10^-3 to 10^-7Scm^-1, Niterra's solid electrolytes achieve ionic conductivity as high as 1.4 x 10^-3S/cm.

Stability to Li metal

Highly electrochemically stable, stable to Li metal, no reaction with Li metal after 5 weeks, stable ionic conductivity can be maintained.

Excellent Temperature
Characteristics

The batteries can be used over a wide temperature range, whereas the upper operating temperature limit for conventional lithium-ion batteries is 60°C.

OXSSB🄬* went to the Moon

Niterra is currently participating as a corporate partner in HAKUTO-R, a commercial lunar exploration program operated by ispace Inc.
We conducted the world's first solid-state battery demonstration test in the harsh environment of high/low temperature fluctuation, vibration, and vacuum of space.

We have acquired the trademark "OXSSB🄬", which stands for "Oxide Solid State Battery" in Japan.
