BASF invests $50 million to acquire equity ownership position in Li-Sulfur battery company Sion Power

BASF has invested $50 million to acquire an equity ownership position in privately held Sion Power, the leading developer of rechargeable lithium-sulfur (Li-S) batteries. Sion Power’s Li-S technology provides rechargeable cells with a specific energy of more than 350 Wh/kg—50% greater than the currently commercially available rechargeable battery technologies. More than 600 Wh/kg in specific energy and 600 Wh/l in energy density are achievable in the near future, according to the company.

This equity partnership expands upon an existing joint development agreement that BASF Future Business GmbH established with Sion Power in 2009 to accelerate the commercialization of Sion’s proprietary Li-S battery technology for electric and plug-in electric vehicles and other high-energy applications over the next decade.

Dr. Dennis R. Mangino, CEO of Sion Power, said that the progress of the technical collaboration led BASF to take the significant financial stake in Sion.

We are delighted to strengthen our ties with Sion Power, which will allow us to leverage the expertise of both companies to deliver leading-edge lithium-sulfur technologies to the battery materials market in the years ahead.

—Dr. Andreas Kreimeyer, member of the Board of Executive Directors and Research Executive Director of BASF SE

The agreement with Sion Power provides a long-term complement to BASF’s current activities in the areas of electrolyte formulations and lithium-ion cathode materials development, including its start-up of an advanced cathode materials manufacturing plant in Elyria, Ohio, later this year. These initiatives are being managed under BASF’s new global business unit “Battery Materials,” which was launched on January 1, 2012, to integrate the company’s current and future battery materials-related activities within a single operating unit managed by its Catalysts division, based in Iselin, New Jersey.

BASF had previously announced its intention to invest a three-digit million euro sum in researching, developing and producing advanced battery materials through 2016. The company is also exploring next-generation battery materials concepts, including the lithium-sulfur technologies now in early stage development with Sion Power.



BASF are pragmatic people so if they invest in Sion, means there is something there, but still not a guarantee that it will work. This Li-S chemistry being particularly tricky


BASF is good at chemistry and materials, perhaps they can help with the advancement. This is what good capital investment should be, they bring more to the agreement than money.


This is very good news for further Li-Sulfur battery development. BASF has the capabilities required to develop and mass produced improved Li-S batteries for future extended range electrified vehicles. More competition the better.


@SJC: very well said


Thank you Green, I have my moments :)


I am not sure that it will be the perfect battery for car, the problem is that one electrode is pure Li in contrast to Li-ion where Li is only used to carry charge as a result this battery requires a lot of Lithium, given the size of a car battery known resources of Li might not be adequate


Last I knew there was more than enough lithium for any conceivable adoption of EV's. Pure Li electrodes will also be easier to recycle and recover.
