- For Lithium-ion batteries to find widespread use in electromobility and stationary energy storage applications, manufacturing costs must be lowered. Pilot-scale technology development represents a key link between fundamental laboratory investigations and industrial process development.
To this end, thyssenkrupp System Engineering GmbH and Fraunhofer IKTS have been operating, since 2012, an application center with a 300 m² dry room at the Pleißa site near Chemnitz. The pilot line is used for connecting research activities and industry value added. The complete production chain, encompassing slurry preparation and characterization, electrode coating, and calendering, cutting of the coated electrode tapes, assembly of the battery, electrolyte filling, and cell formation, is mapped and optimized in a collaborative process.
One core activity is the scale-up and optimization of coating and production technologies for efficient, resource-saving, reproducible mass production of lithium-ion batteries. In addition to existing technological approaches, new methods are considered and adapted for accelerating transfer to industry.
Research partners also address topics, such as in-process tape handling, design of the manufacturing environment, and realization of efficient process monitoring. Efficient process monitoring is crucial for rapidly achieving industrial-scale production capabilities and thus keeping system costs at a competitive level. The partners can draw on their mechanical engineering expertise to adapt production equipment to customer requirements.
Besides being used to conduct publicly funded joint projects, the pilot facility is available to interested industry customers from all stages of the value chain. The joint service offer includes the following:
- Materials testing
- Testing and optimization of established as well as new material and technology concepts
- Development, testing, and optimization of integrated manufacturing concepts
- Scale-up and technology transfer
- Feasibility studies and consulting

So what is the average cost for such lab / production line you showed in this video ??
that's cool. Thanks for sharing :)
Comparing this to the production of lead-acid batteries is incredible. Lead acid factories look like iron plants (very dusty) but this looks like a cleanroom. Fascinating!
It has to be because lithium is very reactive.
Hi, I watched your video on Lithium battery electrode reduction.
Please can you give the the complete list of the raw materials
And there ratio .
What kind of device is on 2:28 and what "Inline measurement" does it perform?
What is the base copper foil thickness and characteristics, are only ED copper foils used, can RA copper foils be also used, we produce copper foils RA, from 15micron onwards, just curious whether RA copper foils are also used in making the anode current collectors : TIA
I will visit this facility very soon, see you there!
I want to visit too please can you write me
Electrode making is so pleasing
Kolego pracuje przy produkcji bateria na dziale katoda nie ma w tym nic przyjemnego

The coating station is equipped with gravure cylinder or anilox roll ?
As coating tool a Dr Blade or Slot die system is used without any gravure coating.
Where can I get this line ?? , Can anyone help.
hello, we want to start production of batteries in Uzbekistan. how much does a full line cost?
What are the dimensions of the electrode being produced here? And what type of coating material is being used?
We typically coat graphite or silicon based materials on copper (10-20µm) and oxides (like NCM) or phosphates (like LiFePO4) on aluminum foil (15µm-20µm), respectively, as electrodes (anodes and cathodes) for lithium-ion batteries. For anodes the process is typically water based, for cathodes either water on NMP based. The maximum width of this coater is 300 mm. with a speed of approx. 0.5 - 1.0 m/sec depending on the wet film thickness. Keep in mind that this is a coater used for research & development, so it is designed for flexibility rather than for max. speed and throughput.
@@FraunhoferIKTSsht talker!
What is the average cost such lab production unit
What kind of battery do you need to make.
pouch cell, cylindrical ， prismatic, coin。。。
How many meters of coated electrode is required to deliver 100 Wh/kg energy density
Energy density is a property of a cell or battery and does not scale with the area of the electrode. Maybe you meant ‘… is required to deliver a cell with 100 Wh energy’? In this case, assuming an areal capacity of 3 mAh/cm² and a voltage of 3.7 V you have an ‘areal energy’ of 0.0111 Wh/cm². So, you would need roughly 9000 cm² each of anode and cathode to manufacture a 100 Wh energy cell (or in capacity 100 Wh/3.7V = 27 Ah). (rough estimations!)
Can you please provide the cost of your machine for a medium scale industry.🙏
Go on their site and contact them directly :)
This is same manufacturing method of Tesla new 4680 cell .
What kind of device is on 0:54 ?
This is a grindometer which is used to measure agglomerates.
I actually with a can make tools, so that I can make even better stuff.
Not a lot of people watch this stuff, and it'll probably not go viral for years...
Lets see if we will meet again in some years

What is the cost of the total set up
At the Battery Technology Application Center, industrial clients find various technological facilities which allow to transfer continuous production processes from the lab to the pre-industrial pilot scale. Consulting in the field of technology transfer is available on request. Regarding the EMBATT - technology the main target is the development of an economic beneficial system set-up. A realistic cost target in the phase of final industrialization is a system cost approach of 150€/kWh. Actually these goals are achieved step-by-step with scale-up and cost-reductions on material and processing level with industrial development partners.
