Siemens acquires stake in energy storage manufacturer Skeleton Technologies

Siemens AG, together with its financial services provider Siemens Financial Services (SFS), has taken an undisclosed stake in Estonian supercapacitor specialist Skeleton Technologies. Siemens is thus part of a €108 million financing round in which existing investors such as Japan's Marubeni Corporation were joined for the first time by Brazilian mining giant CBMM. With the completed round, Skeleton's total funding exceeds 300 million euros.
The company intends to use it to »accelerate the development of next-generation products and finance the manufacturing expansion for supercapacitors and the company’s new high-power battery technology – the SuperBattery«. The »SuperBattery« is a new generation of supercapacitors based on curved graphene developed by subsidiary Skeleton Materials in Bitterfeld-Wolfen. Although supercapacitors do not reach the power densities of batteries, they can be charged and discharged particularly quickly and are characterized by especially high cycle numbers.
For Siemens, this is more than just a financial investment. The two companies have also joined forces to automate and digitize Skeleton's planned SuperBattery factory in Markranstädt near Leipzig. The factory is scheduled for completion at the end of 2024
