Challenging further evolution and transformation of electrolytes through integration synergies.

MU Ionic Solutions Corporation (MUIS) was founded in October 2020, as a joint venture company between Mitsubishi Chemical Corporation and Ube Industries, Ltd., and engaged in business of electrolytes for lithium-ion batteries.

In order to maximize the effect of integration synergies, we have set three slogans: communication, fusion, and transformation. Based on fusion of knowledge and technology, we are challenging further evolution and transformation of electrolytes.

In addition to our manufacturing sites, we are also collaborating with the manufacturing sites of Mitsubishi Chemical Group and responding to our customers’ high-quality requirements on a global basis.



What is electrolyte?

Electrolytes are ionic conductive solutions that are important components for smoothly charging and discharging lithium-ion batteries and for suppressing battery degradation.

Differentiation of additives has become a source of technological power because various functions can be added by the additives to be blended.

Both Mitsubishi Chemical Corporation and Ube Industries, Ltd. began producing electrolytes for lithium-ion batteries in the 1990s, and have provided electrolytes containing unique additives of their own. By combining the technologies and expertise of the two companies that have accumulated over many years, we will continue to create new electrolytes that meet the needs of the times.




An organic solvent-based electrolyte, mainly used for lithium-ion batteries, as well as lithium primary batteries, aluminum electrolytic capacitors, etc.

Our electrolyte can greatly improve battery performance, including power output and lifetime, with functional additives tailored to the purpose, such as electrode interface control and prevention of overcharging (improving safety).
Lithium-ion batteries, electrolytes for batteries such as lithium primary batteries, electrolytes for capacitors such as aluminum electrolytic capacitors, etc.
