NEG: Crystallized glass as the positive electrode material: Na-ion secondary battery
-Successful room temperature drive-
November 8, 2017
Nippon Electric Glass:
We made a prototype of “all-solid-state Na-ion secondary battery using crystallized glass as the positive electrode material”.
This time, it announced that it succeeded in driving at room temperature.
It is said that this is the world’s first successful example of using crystallized glass as a positive electrode material.
The structure is simple:
By “developing a high-potential active material”, a high energy density battery can be manufactured.
Use sodium, which is abundant in resources.
Compared to lithium, which is a rare metal
There is no concern about supply.

About all-solid-state Na ion secondary battery
We have developed a new crystallized glass negative electrode material.
Crystallized glass positive electrode, integrated with solid electrolyte,
We succeeded in driving an all-oxide all-solid-state Na-ion secondary battery for the first time in the world.
All-solid-state Na ion secondary battery:
With an output voltage of 3V, it has practicality comparable to that of a lithium-ion secondary battery.
Our all-solid-state Na-ion secondary battery uses sodium and iron as materials.
No need for rare metal elements:
It does not require any rare metal elements such as lithium, cobalt and nickel.
No ignition or harmful gas:
It is composed of a stable oxide material.
No ignition or harmful gas is generated even if a nail or knife sticks.
Results of this development:
We will report at the 62nd Battery Discussion Meeting (at Pacifico Yokohama), which will be held from November 30th.
