LANXESS Opens Krefeld Lab to Test Iron Inputs for LFP Cells
LANXESS has opened a battery laboratory at Krefeld-Uerdingen in Germany, where it will test its iron oxide and iron phosphate grades inside working LFP battery cells.
Specialty chemicals maker LANXESS has opened a battery laboratory at its Krefeld-Uerdingen site in Germany to test and develop iron oxide and iron phosphate materials — the precursors for lithium iron phosphate cathode material — directly inside battery cells.
LANXESS has opened a battery laboratory at its Krefeld-Uerdingen site in Germany, giving the specialty chemicals group a place to test and develop the iron-based materials that feed into lithium iron phosphate battery cathodes. The lab works on iron oxide and iron phosphate — the precursor chemicals used to make LFP cathode material — and, crucially, allows the company to check how those products behave inside an actual battery cell rather than only on a bench.
That last detail is the substance of the announcement. Chemical producers have long been able to characterise a powder: particle size, surface area, purity, crystal structure, trace metal content. What they have often had to take on trust, or infer from a customer's feedback months later, is how those attributes translate into cell behaviour — capacity, rate performance, cycle life. A captive cell-testing capability shortens that loop.
Why iron oxide and iron phosphate sit upstream of LFP
Lithium iron phosphate is the cathode chemistry that has taken over the cheaper end of the electric vehicle market and most of stationary storage. It gives up energy density to nickel-rich chemistries but wins on cost, thermal stability and cycle life, and it uses no cobalt and no nickel. What it does use, in volume, is iron and phosphorus.
Those come into the cathode plant as precursors. Iron oxide and iron phosphate are the practical starting points: they are blended with a lithium source and processed into the finished cathode active material. Because the cathode is where most of a cell's material cost and much of its performance sits, precursor quality is not a commodity question. Trace metal contamination, particle morphology and consistency batch to batch all show up later as cell defects, gassing, or early capacity fade.
That is why a producer of iron oxide pigments and phosphate chemistry has a credible claim on this part of the chain. The chemistry is adjacent to businesses these firms already run at industrial scale; the hard part is meeting battery-grade specifications reliably and proving it to a cathode maker who has no appetite for surprises on a production line.
The supply chain gap Western producers are aiming at
LFP's rise has been overwhelmingly a Chinese industrial story. Cathode material capacity, precursor supply and the process know-how to run it at yield are concentrated there, and Western cell projects that choose LFP have generally had to import the cathode or license the process. European and North American policy — local content rules, subsidies tied to sourcing, tariff exposure — has made that dependence uncomfortable for automakers planning a decade out.
Breaking into it from the top of the chain is arguably the most tractable route. Building a cell gigafactory is capital-hungry and slow. Qualifying an iron phosphate grade into someone else's cathode plant is a chemistry and quality-control problem, and European specialty chemical firms already own the assets, the permits and the process engineering to attempt it. As Charged EVs reported, the Krefeld-Uerdingen laboratory is aimed squarely at that qualification work.
The commercial logic is that the customer is not the carmaker. It is the cathode producer, and behind that the cell maker. Those buyers move slowly and test exhaustively. A supplier that can arrive with cell data attached to its material specification — rather than asking the customer to generate that data — has a shorter path through the door.
What a cell-testing lab actually changes
In-house cell testing does three things for a precursor supplier.
- It compresses development cycles. Formulation changes can be screened against cell performance in weeks rather than waiting on an external partner's queue.
- It creates a shared language with customers. Cathode and cell makers assess materials in cell terms. Being able to present results in those terms removes a translation step from every technical conversation.
- It supports differentiation. If a particular iron oxide morphology or a lower impurity ceiling measurably improves cycle life, that is a case for a price premium over a generic import.
None of that guarantees offtake. Qualification into a battery supply chain typically runs through sample stages, pilot lines and multi-year audits before a purchase order of any size appears. A laboratory is the entry ticket, not the destination. What it signals is that the company intends to sell into LFP as a developed product line rather than opportunistically shipping tonnes of industrial-grade powder.
The demand backdrop and what to watch
Qualification into a battery supply chain typically runs through sample stages, pilot lines and multi-year audits before a purchase order of any size appears.
The pull for LFP precursors comes from two directions at once. Entry and mid-price electric vehicles have moved toward the chemistry to hit sticker prices, and grid-scale storage — where weight barely matters and cycle life is everything — has become a large and fast-growing buyer in its own right. Both argue for more precursor capacity outside China over the coming decade, assuming European cell projects reach the volumes they have announced.
The counterweight is price. Chinese LFP cathode material has been cheap, and any Western precursor has to clear a cost gap that policy support may narrow but does not erase. That is the strategic bet embedded in a lab like this one: that buyers will pay something for security of supply, local content compliance and technical service delivered in the same time zone.
Equity markets were not reacting to the news in any visible way. Broad benchmarks were firm in Wednesday trade, with the S&P 500 tracker (NYSEARCA: SPY) at $760.58, up 0.42% on the day, and the Nasdaq 100 fund (NASDAQ: QQQ) at $711.15, up 0.94%, as of 15:25 GMT on 16 September 2026. The Dow 30 tracker (NYSEARCA: DIA) was flat at $521.11, down 0.02%. Materials announcements of this kind rarely move a diversified chemicals share price on the day; they matter through order books years later.
The markers worth watching from here are concrete ones: whether LANXESS names cathode or cell customers, whether sample supply turns into a qualified grade, and whether the company commits capital to production capacity behind the laboratory. Until then, Krefeld-Uerdingen is a statement of intent about where the company thinks the LFP chain will be sourced.

Frequently asked questions
What did LANXESS open in Krefeld-Uerdingen?
LANXESS, a specialty chemicals company, opened a battery laboratory at its Krefeld-Uerdingen site in Germany. The facility tests and develops battery materials based on iron oxide and iron phosphate, and allows the company to evaluate the material properties of its products directly inside battery cells rather than relying only on powder characterisation.
Why do iron oxide and iron phosphate matter for batteries?
They are precursor chemicals used to make lithium iron phosphate, or LFP, cathode material. Blended with a lithium source and processed, they become the cathode active material in an LFP cell. Their purity, particle structure and batch consistency directly influence cell capacity, cycle life and defect rates downstream.
What is LFP and why is it popular?
Lithium iron phosphate is a battery cathode chemistry that uses no cobalt and no nickel. It offers lower energy density than nickel-rich chemistries but better cost, thermal stability and cycle life. That combination has made it the default choice for lower-priced electric vehicles and for grid-scale stationary energy storage.
Who would buy LANXESS's iron phosphate materials?
The immediate customers are cathode active material producers, and behind them the battery cell manufacturers and automakers. These buyers run long qualification processes involving samples, pilot lines and audits, so a precursor supplier typically waits years between first contact and meaningful commercial volume.
How does this relate to China's position in the battery chain?
LFP cathode and precursor production is heavily concentrated in China, and Western cell projects using the chemistry have largely depended on imports. European specialty chemical firms already own relevant assets and process knowledge, making precursor supply one of the more achievable entry points for building a non-Chinese LFP chain.
Did the announcement move markets?
There was no visible market reaction tied to the news. Broad benchmark funds were firm in Wednesday trade, with SPY at $760.58, up 0.42%, and QQQ at $711.15, up 0.94%, as of 15:25 GMT on 16 September 2026. Materials qualification announcements usually affect results only over multi-year horizons.
