Safe and long-lasting cell chemistry: Which future markets does LFP support?

23. July 2026

LFP is regarded as a highly mature cell chemistry. Like any other chemical structure, lithium iron phosphate determines the fundamental properties of the battery pack in which it is used. The standout features of LFP include high safety, a long service life and exceptional reliability. However, its energy density is lower than that of conventional lithium-ion compounds. For the same power output, this results in heavier battery packs and requires a larger installation space. Yet solutions are emerging in this regard too.

Petro Luft is CCO of Reliance Lithium Werks, an internationally active company specialising in the development and production of LFP cells. Lithium Werks is also a long-standing partner of Omntrion Griese GmbH for lithium iron phosphate-based cells. “We particularly enjoy working with Lithium Werks in the medical and wind energy sectors,” says Omntrion CEO Adrian Griese. “A long service life is hugely important for these applications, and Lithium Werks has confirmed the cycle stability of its cells for ten years.” Petro Luft takes his assessment of the cells even further. He says: “Lithium Werks is known for ‘high performance’. We build the Ferraris of the cell world.” However, the target parameters of the battery pack applications and cost-efficiency ultimately determine which cells and cell chemistries are suitable for which applications. LFP specialist Petro Luft outlines which products and markets LFP can position for the future:

LFP in mobile power supply

In mobile power supply, LFP is always the first choice whenever safety and longevity are more important than the weight of the portable or vehicle-mounted product. In shipping, for example, it is essential to ensure safety on the high seas. Conventional lithium-ion technologies can catch fire – a fire that cannot be extinguished, but can only be cooled as much as possible until it blows out of its own accord. The automotive industry also faces this challenge, which it is increasingly resolving through LFP cell chemistry. “LFP does not burn spontaneously,” says Petro Luft. “Not even if the battery is damaged or overheats. NMC, on the other hand, burns – even underwater – as soon as it comes into contact with oxygen. Of course, there are solutions here too that meet safety requirements – for example, through the design of the battery pack itself, a non-flammable plastic casing, or via the battery management system.”

Fundamentally, the cycle stability of lithium iron phosphate is important for mobile applications – just as much as the high charging currents. “If I use a forklift for eight hours a day and then charge it for 16 hours, I don’t need LFP,” says Petro Luft. “But if I want to use it round the clock across three shifts, I need a battery pack that can be charged to 100 per cent within thirty minutes.” The cycle stability of its cells is crucial to the battery pack’s long service life. Compared to NMC, for example, an LFP cell can be charged and discharged two to three times as often. Under certain conditions, up to 15,000 life cycles per cell are possible, meaning it remains operational for several years longer. Owing to these properties, a number of manufacturers of mobile applications in the fields of robotics and transport logistics, as well as professional garden and power tools, have already switched to LFP cells. “After all, no craftsman wants to wait two hours for their drill or sander to recharge.” LFP is generally ideal for devices that are charged regularly, are expected to function reliably for many years and are operated at higher ambient temperatures. For small battery packs in professional, industrial or stationary applications, LFP is therefore often the best choice, both technically and economically.

LFP in medical technology

In the medical sector, LFP is already established as a safe cell chemistry. Whether medical power tools such as bone saws, measuring and laboratory equipment, defibrillators, medical lamps, mobile patient monitors or portable ultrasound devices – they all require the highest possible level of safety to protect patients and medical staff. Furthermore, many medical devices require high power output for short periods, for example when switching on or when operating pumps or compressors.

A second area of medical application also relies on the short-term but very high charging currents of battery packs containing LFP cells. In the event of a power cut, every hospital must ensure an uninterruptible power supply (UPS) – whether to maintain lighting and the operation of electrical instruments during surgery or to keep life-support machines running. “However, it takes two to three minutes for a diesel generator to start up in the event of a power cut,” says Petro Luft. “To bridge this gap, we need a UPS system with a battery that can withstand a very high load for a short period.” Such UPS systems are based on highly advanced LFP cells, which can also be used in any other building or even data centres.

LFP in other growth markets

“Essentially, we can put LFP to good use almost anywhere. Wherever there are batteries, there is a market for LFP,” says Petro Luft. “The question is when it is worth switching from the old chemical structures to LFP. Replacing cells in an existing pack means both adapting the design and renewing the certifications. But looking to the future, LFP will become the leading lithium-based cell chemistry by 2030, achieving a return on investment ever more quickly.”

Even today, alongside medical technology, wind power generation, for example, is based on LFP cell chemistry. This is due to the high number of possible charge cycles, which are a priority requirement in these applications. Another promising field for lithium iron phosphate lies in various starter batteries – for aeroplanes, helicopters or motor vehicles. Furthermore, electric mobility requires a second safety battery that can deliver higher peak currents for short periods to open automatic doors or windows and activate other safety measures. “If the power to the electric drive fails due to a faulty or even burning battery, I won’t be able to get out of modern cars without a backup battery.” Last but not least, another future market lies in the electrification of off-grid vehicles and so-called Non-Road Mobile Machinery (NRMM), such as construction machinery including excavators and bulldozers, road sweepers or tractors.

LFP in the circular economy

LFP is one of the most sustainable and ethically sound cell chemistries, simply because no nickel or cobalt is mined or used in its production. In theory, LFP is also easy to recycle within the circular economy, though this remains to be proven. “Around 2020, LFP first became attractive to the mass market and many users switched to this chemical composition,” says Petro Luft. “The main driver here was the automotive sector.” This also means that it will not be until around 2028 that large volumes of end-of-life LFP cells will become available for the circular economy. “Recovering LFP will be of little economic appeal, but it is entirely possible to recover the so-called ‘black slurry’, and the legal regulations stipulate that this will happen. However, it would make even more sense to simply continue using the cells in a ‘second life’ outside their original application. Cells from a coach’s battery, for example, can easily continue to be used for another five to six years in a home energy storage system.”

LFP in Research and Development

At present, the advantageous properties of lithium iron phosphate are offset by the higher investment costs and lower energy density of the cells. However, development initiatives and initial solutions are already emerging in this area too. Adding magnesium increases the capacity of LFP cells by up to 25 per cent. “So-called MLFP is just the first step,” says Petro Luft. “Researchers are experimenting with various materials that provide a capacity boost and could already make LFP almost competitive with NMC.”

Lithium Werks has pursued a different approach itself and developed its own technology, Nano-LFP. “The phosphate in the form of these microscopic particles can deliver very high currents and thus charge very quickly. We developed it for high-performance Formula One cars in collaboration with our US partners at the University of Boston.” The capacity of Nano-LFP can also be increased with magnesium additives. Titanium offers these possibilities as well.

Specific optimisations of LFP cell chemistry are already in use, but do not yet offer a price-performance ratio suitable for broader markets. It remains to be seen which variants will prevail. What is clear is that the cell chemistries of the future will be continuously optimised. “And alongside the further-developed lithium iron phosphate cells, we will see cells based on entirely new chemistries, such as sodium-ion,” says Petro Luft. “These, in turn, will enable new, optimised battery pack characteristics. And so there will always be specific chemical structures for specific applications, from which the most suitable one must be selected.”
