NIPPON SHOKUBAI: Improvement of facilities and patent rights for the lithium-ion battery electrolyte IONEL (LiFSI)

19 January 2021

NIPPON SHOKUBAI CO., LTD. ( https://www.shokubai.co.jp/en/ ) has decided to start designing new systems "IONEL TM - Lithium bis (fluorosulfonyl) imide [LiFSI]" for lithium-ion batteries start. For this purpose, the "IONEL Construction Team" was founded on October 1, 2020 to build new production facilities (annual production capacity: 2,000 tons; location: Ichikawa, Chiba) using our own process. The decision was made because the current annual production capacity of 300 tons is insufficient for the increasing demand. Commercial production of the new plant will begin in spring 2023.

IONEL has an excellent effect on improving the service life, the charge / discharge rate and the durability of the batteries at low / high temperatures. With this excellent effect, our product enjoys a high reputation in the industry.

In order to meet our customer demand, in addition to efforts to improve the performance of our product, we have made efforts to protect our product by filing and securing a number of patents including the 44 patents listed below.

We kindly ask all persons reading this announcement to take care not to infringe our patents by buying, selling or using products that use our patents of other companies not related to NIPPON SHOKUBAI.

We aim to keep making efforts to further improve and develop our product with better technologies. We would be very grateful if you would continue to support our product.
