Asahi Kasei: Making LIB solvent from CO2:
-Contributing to reducing CO2 emissions-
Asahi Kasei:
We have developed “a technology to make a solvent for lithium-ion batteries from CO2”.
Nihon Keizai Shimbun
(June 17th)
“Asahi Kasei will put it to practical use in 2023,” It reported.
Solvent for LiB electrolyte:
We have developed “a technique for producing a solvent used for an electrolytic solution, which is a main component of a battery”.
Solvent preparation using CO2 as a raw material:
In the conventional technique, a solvent is prepared from a fossil raw material.
With this technology, a solvent is prepared from CO2.
Licensed for technology:
Due to the simplicity of the process, the technology is licensed without enclosing it.
The initial cost of the equipment is 30% cheaper than the existing method.

– Asahi Kasei Highly purified carbonate
(ethylene carbonate and dimethyl carbonate) production technology Carbonate
is a commodity organic chemical used as solvents, paints, pharmaceutical raw materials, gasoline additives, electrolyte components for lithium-ion battery(LIB), etc.
Ethylene carbonate (EC) is white solid, and dimethyl carbonate (DMC) is colorless liquid at normal temperature.
We have started licensing
the production technology of highly purified EC and highly purified DMC by utilizing the PC production technology (2019).
50 wt% of EC and 31 wt% of DMC are originated from CO₂ respectively,
so they are environmentally friendly processes that consume CO₂.
Major application of highly purified carbonate solvent
～electrolyte component for lithium-ion battery
Lithium-ion batteries are storage batteries installed in electric vehicles(EVs).
Major application of highly purified carbonate solvent- electrolyte component for lithium-ion battery
The electrolyte used in lithium-ion battery generally consists of a mixed solvent of the following five types of organic solvents, lithium salts and additives.
Highly purified EC and highly purified DMC produced by our technology
have realized extreme high purity and can be applied for electrolyte component.
Highly purified EC and highly purified DMC produced by our technology
are prepared into electrolyte by an electrolyte manufacturer, transported to a LIB manufacturer, and used as a LIB material.
We believe
it also necessary to make components of LIB electrolyte used for EVs that don’t emit CO₂ and are environmentally friendly, using environmentally friendly technology.
In fact,
we have received many inquiries to our highly purified carbonate production process technology from many manufacturers in Europe and other countries with high environmental awareness, and are proceeding with licensing activities around the world.
