Idemitsu: To produce solid electrolyte for all-solid-state LIB: Demonstration equipment in operation
Idemitsu Kosan:
On November 5, construction of a demonstration facility was completed for “commercial production of solid electrolytes for all-solid-state lithium-ion batteries.”
Announced that it has started operation in the Chiba office. Twice
All-solid-state lithium-ion battery:
A type of lithium-ion battery
Ion conduction between the positive and negative electrodes,
It has the characteristics of a solid electrolyte.
It is being developed as a next-generation battery.
Early commercialization is required for EVs.
Key material
Solid electrolyte
“Needs for solid electrolytes, which are the key materials” have been increasing in recent years.
By using this device
Demonstration of mass production process of solid electrolyte
Aim for early commercialization.
Established high-purity lithium sulfide production method:
Idemitsu Kosan has established a high-purity lithium sulfide production method cultivated in the petrochemical business.
We also hold numerous patents for sulfide-based solid electrolytes made from lithium sulfide.
Practical application of the technology accumulated so far.

Idemitsu Kosan: Japan’s leading all-solid-state battery
-Now of cutting-edge research on “materials”-
Idemitsu Kosan:
Idemitsu Kosan is one of the world’s top class battery materials.
An industry male with over 170 patents.
Development of electrolyte materials:
Japan is leading the way in material development.
Mitsui Kinzoku has also introduced mass production test equipment for sulfide-based electrolytes.
Sulfide-based solid electrolyte material:
Medium-large all-solid-state batteries installed in automobiles.
Sulfide-based solid electrolytes are expected to be adopted.
Characteristics of sulfide-based electrolytes:
In the sulfide system, lithium ions move quickly in the electrolyte.
Since it is softer, it has the advantage of being easy to fill the gap between the positive and negative electrode materials.
In particular, it is important to create a boundary surface through which ions can pass without interruption between the positive and negative electrodes and the electrolyte.

Start of Operation of Verification Facility aimed at Commercial Production of Solid Electrolytes for Next-generation Batteries
November 5, 2021
Idemitsu Kosan Co.,Ltd.
is pleased to announce that it has built and started operation of verification facility at Chiba Complex,
one of its main complexes, for commercial production of solid electrolytes for All-Solid Lithium Ion Rechargeable Batteries,*1
which show promise as next-generation batteries.
There is a demand for early practical use of All-Solid Lithium Ion Rechargeable Batteries for applications
such as EVs, leading to growing needs in recent years for solid electrolytes, the key material for such batteries.
With the goal of early commercialization,
the facility will be used to proceed with verification of solid electrolyte mass-production processes
Idemitsu has established a method for manufacturing high-purity lithium sulfide developed in its petrochemical business,
and holds many patents for sulfide solid electrolytes that use lithium sulfide as their raw material.
With the aim of putting into practical use technologies that have been amassed over the years and establishing integrated production from raw materials and a stable supply system,
