“Complete replacement” Lithium-ion technology “difficult to imagine”

Article menu

Prof. Dr. Peter Birke from the Institute of Photovoltaic The University of Stuttgart talked to Battery-News about the limits of the technological development of batteries, hydrogen and synthetic fuels as possible alternatives and the benefits of Germany for the production of battery cells.

“There will be no miracle battery,” says Birke about future developments in the battery area. Among other things, these would be influenced by the limited raw material availability as well as the increasingly important sustainability criteria, as well as having an optimal mixture between “energy density and performance, life, security, cost”. This will always accompany and limit the development of future batteries.”Therefore, as an alternative,” the view of the fuel cell and synthetic fuels that are produced CO2-neutral is becoming increasingly important.”He see” a juxtaposition of three technologies, battery, fuel cell, synthetic fuels “. The fuel cell can be its strengths with large means of transport and is optimally designed for many stationary applications, synthetic fuels are conceivable as a sustainable option for long-haul aircraft and container ships.

As technologically particularly promising for the further development of battery technologies, Birke “first quite particularly all aspects of digitization” as well as “alternative binder and solvents, quasi-continuous paste mixers, which work on the minute while working and dosing and distributing electrolytes”. Also interesting is the use of artificial intelligence “during formation (the first loading of a battery cell) and the reliable detection and evaluation of cell damage after the multi-week storage process in production.”

“Remarkable market shares also possible for European and German cell manufacturers”

Since the demand for battery cells with the rising number of electric cars is steadily increasing, birch in the interview is strong for a production on site in Europe: “Batteries are built where cells are, and the cell must come to the battery and not reversed. So there must be large cell production for lithium-ion cells in Europe, as long as you also manufacture electric cars there.”The battery expert also refers to” notable market shares for European and German cell manufacturers “, which would be still possible for the right course:” The production site Germany can still be determined in this respect, but the time is running off.”

The digitization can also act as “enabler”, “for a considerable competitive minimization of production fluctuations.”So” again considerable cost reductions and an increase in the quality of batteries are possible.”An important lever is also the reference of the raw materials:” About 70 percent of the costs of a lithium-ion battery cell are material costs, “says Birke. “So at the same time, sustainable supply chains must be established and ensured in the long term, as well as attractive prices for cells about skilled raw material purchasing or buying. Purchasing the cell materials are secured, “he recommends.

“This is a big new lighthouse on the horizon!”

Germany thanks to its strong research landscape, the best prerequisites for battery cell production, Birke finds: “There is no doubt in Germany excellent basic research for innovative battery cell technologies as well as the cell materials”, with “Process Technologies for Battery Cells resp. a production research for battery cells “, on the other hand, reign for catching up. Important is “much more applied and production-related battery cell research and development. There is still the gap “which birch is closed by the mid-2022 launching Fraunhofer Research Production Battery Cell (FFB) in Munster. “The aim of the research factory is, among other things, to reduce the investment risk for cell production. This is a big new lighthouse on the horizon!”

“That lithium-ion technology disappears in the coming decades is extremely unlikely,” says Birke about a possible successor of the most common battery technology. At large stationary battery, lithium sulfur is a promising candidate, also “due to the extremely attractive price for sulfur”, basically “a waste product of the industry.”From 2025, the researchers expects” serious solutions “from the field of solid state battery. “A complete replacement” of lithium-ion technology is “difficult to imagine“. It will give “rather about long periods of co-existences”. That lithium-ion technology disappears in the coming decades, birch holds for “extremely unlikely”.

  1. Mr Birke, probably shortly before the emeritation, is absolutely not at the level of science and technology, let alone informed or even partners on perspectives for battery.-technology. I refer to the latest Catl and Tesla patents, as well as the Battery Day in June. And something like this is the future of Germany, yes great. We are already on the siding and always move to the horn of our steam locomotive.

  2. expert ? Hi ! This year, a BYD car with LFP cells to Europe (trucks and buses travel long in the world) ! LFP now have 75% power density of lithium ions, but they are comparatively extremely insensitive, the battery magage can be much easier, cheaper and lighter. The power is likely to be almost identical and the new technologies of Tesla are still on the street this year. Leisurely further sleep Germany, but not forgotten: continued to spare massive taxpayers !

  3. Who is Professor Doctor Peter Birke??
    Even a named professor or doctor. Doctor in what? Or simply one of his own opinion who really does not care about public?
    Would be nice if you would not do such items even public.

  4. My hope was that from the point of view of the auto industry as well as the Federal Republic and the economy
    and the battery availability all these German companies together develop a battery together, which will build a replacement station at a maximum of 50 kilometers! I hope now that finally the competitive idea at the German
    Industry is overcome and soon results in this area visible to secure location Germany to secure longer term! Greeting Reinhard Hellwig

  5. Oh, there are all the part-time battery chief developer again. First of all, I would wait the Battery Day and remember that Tesla is not necessarily known for compliance with announced dates. I like to remember the autonomous driving which has been pushed several times in the year. Or the much announced new roadster recently postponed by 2 years. So as long as no new Wonderkku Real is installed in series, I do not think so.
    The fact is certainly that a large part of the battery expertise in Asia sits, in South Korea and China. On behalf: Catl, LG Chem, Samsung, Panasonic etc. The field was left to the past decades. But not necessarily Tesla. Big announcements have only come from the Tesla corner so far (see appointment reliably above). Realer and more frequent statements are rather from 2025-2030, until there is something new. Point One is the development, point 2 the large-scale implementation and control of the process (high number of high quality with low scattering) and point 3 is the production at competitive prices (new technologies are often more expensive)

  6. I remember that in the 70s of fantastic people was claimed, the flat screens are not feasible. The geometry of the brown tube could not be added

  7. Is a bit off-topic:
    @ Karl: My knowledge was the problem at that time not the stupidity or ignorance of the engineers, but simply the non-existent technique, extremely tarpaulin glass surfaces in the necessary size can be produced. For a calculator display with LCD technology, that already worked for more but not.

  8. Love commentators,

    With 53 has Kai (!) Peter Birke still 14 years to the emeritation. First make smart before you write stupid stuff over the man.
