The Li-Tec Battery GmbH was until 2015 a German developer and manufacturer of lithium-ion battery cells . After giving up cell production, the company works on "research and development in the field of new energy storage technologies".

In February 2017 it became known that the German manufacturer of industrial high-performance batteries, LIACON GmbH from Itzehoe, had taken over all Li-Tec systems and machines as part of an asset deal .

Corporate development

The company was founded in 2006 as Li-Tec Vermögensverwaltungs-GmbH by Evonik Industries AG and is still managed today in the legal form of a GmbH . This was in 2008 with the participation of Daimler AG , the Li-Tec Battery GmbH produces - from then on temporarily a joint venture of Evonik Industries AG (50.1%) and Daimler AG (49.9%). The company is based in Kamenz in Saxony . These ownership structures changed in 2014: on April 1, 2014, it became known that the Daimler Group had completely taken over the shares in Evonik Industries. Since then, Li-Tec has been a wholly owned Daimler subsidiary. Li-Tec Battery developed, produced and sold large -format lithium-ion battery cells for automotive applications and battery systems for industrial and stationary applications under the brand name CERIO . However, for economic reasons, production was stopped in December 2015.

In 2016 all company shares were taken over by Daimler AG. Daimler operates the company as a pure development company for battery cells. The development and production of the drive batteries is carried out by the sister company Deutsche Accumotive .

Batteries for the Smart

Smart Fortwo 451 (2012-2015)

From 2012 to 2015 the 93 cells for the electric drive version of the Smart Fortwo Type 451 were manufactured in Kamenz. It was the 2nd generation of the body (Type 451, 2007-2015) with the 3rd generation of the electric drive (ED3), whereby the first two were only used in rental car fleets.

Production of the Smart ED3 was discontinued in 2015. The 3000 batteries held as spare parts for the ED3 are used as a battery storage power plant near Hanover .

The successor is the Smart Type 453, which is also being built with four doors in cooperation with Renault. The ED4 electric version has been available since 2017. The battery assembled in Kamenz by Deutsche ACCUmotive consists of 96 cells from the supplier LG Chem and has a capacity of 17.6 kWh.

A patented separator is used for the battery cells , which was developed by Evonik Degussa as part of an interdisciplinary research project in collaboration with several universities. This separator with the brand name SEPARION consists of a microporous ceramic-coated film, which separates the anode and cathode in the cell system. The separator membrane is heat-resistant up to around 700 ° C and also always remains electrically and mechanically stable. The battery cells from Li-Tec have a cycle stability of 4500 cycles with a high current load on the cells, which is significantly longer than the service life of previous cells (1000-3000 cycles). An electric car needs around 100 such battery cells.

Due to their special properties, the cells were first used in so-called KERS systems of Formula 1 . Li-Tec battery cells are used in vehicle models from the German electric car manufacturer e-Wolf . The cells were marketed by Evonik under the brand name Cerio.

In 2013 it became known that Evonik and Daimler were looking for partners for Li-Tec because of the drop in prices for lithium-ion traction batteries (from around 500 euros per kilowatt hour in 2010 to around 200 euros per kilowatt hour in 2013). A failure of the battery joint venture at the time was not considered impossible. The joint venture was completely taken over by Daimler in 2014 after Evonik announced in autumn 2013 that it wanted to exit the battery business because it was not generating enough profit. The search for technology partners will probably continue for Daimler.

In May 2014, Daimler AG announced that it would stop battery cell production at Li-Tec, as it would source the cells for the next generation of the Smart Fortwo from LG Chem . In November 2014, the Board of Management of the Daimler Group decided to discontinue battery cell production at Li-tec at the end of 2015. The production of battery cells for electric and hybrid cars - like the Smart - will not be economical for the foreseeable future. The product is not in demand in large enough quantities for production to pay off. The Daimler works council would like to prevent the end of battery cell production in Kamenz; the union IG Metall has therefore demanded an action plan from the federal government and industry to keep research and production of battery cells in Germany. At the end of 2015, three fully automated production lines from the manufacturer Grohmann, additional semi-automated lines, high-bay warehouses, robots, handling systems and other peripheral components were up for sale at Li-Tec. In the spring of 2017, the German manufacturer of large-format lithium-ion accumulator cells LIACON GmbH from Itzehoe took over all Li-Tec systems and machines. The parties have agreed not to disclose the transaction or the purchase price.

Research and development activities

Both the novel separator membrane and the size of the individual cells require special manufacturing technologies and equipment, which Li-Tec was involved in developing from the manufacture of the first hand-made laboratory samples to automated mass production. The new technology was funded by the Federal Ministry of Education and Research (BMBF) as part of the ProLiEMo joint project . At Li-Tec, too, the entire production process takes place under clean room-like cleanliness conditions and extremely low humidity in order to guarantee the desired product quality and quality consistency. For these conditions, systems and technologies were newly developed or specially adapted by the BMF-funded joint project. The cell production took place in 2011 in what was then the largest drying room in Europe.

Awards

  • German Future Prize 2007 (nomination): The lithium-ion energy storage devices manufactured by Li-Tec Battery and in particular the flexible ceramic separators used were nominated for the German Future Prize 2007. The project “Nano-layer with mega-performance - flexible ceramic separator enables a breakthrough in large lithium Ion Energy Storage ”from Evonik Industries and several universitieshad been proposedby the German Research Foundation .
  • ÖkoGlobe 2009 : The lithium-ion batteries manufactured by Li-Tec Battery were awarded the ÖkoGlobe 2009. Evonik / Daimler won the award in the “Innovative Energy Sources” category.
