Cellforce Group, a manufacturer of high-performance battery cells for electromobility, has entered into a strategic partnership with laser manufacturer Trumpf.

The battery manufacturer will use Trumpf’s lasers to produce high-performance lithium-ion cells. 

'Our goal is to produce one of the most powerful battery cells in the world,' said Dr Markus Gräf, COO of Cellforce Group.

'We want to raise the energy density, performance and fast-charging capability of the battery cell to a new level.' 

Through the partnership, Trumpf will supply laser systems to a new Cellforce pilot plant currently under construction near Reutlingen,Germany. The facility is scheduled to go into operation in 2024 with an initial capacity of at least 100MWh per year – equivalent to high-performance battery cells for around 1,000 vehicles.

'We will bring our experience in the production of battery cells to this partnership,’ commented Dr Christian Schmitz, CEO of Trumpf Laser Technology. ‘Cellforce should benefit from our new application solutions at an early stage and can test our latest laser technology.’

Trumpf has been involved in electromobility from the very beginning and works with all major cell manufacturers. Last year alone, the firm sold more than a thousand lasers for the production of electric vehicles – with the resultant revenue exceeding that made from selling lasers to the production of vehicles with internal combustion engines. In addition to the production of battery cells, automotive manufacturers and suppliers can use Trumpf lasers to serve other applications in the process chain, such as in the battery pack or in the electric motor.

'The laser is the decisive tool for efficient production of battery cells, without which e-mobility would really not be possible,' remarked Schmitz. ‘There are currently more than 30 different laser applications in the production of the cells.’

Cellforce is a joint venture between Porsche AG and Customcells Holding GmbH.
