Scaling battery development
FOM Technologies lab- and pilot-scale slot-die coating tools make it easy to develop and demonstrate new slot-die-based battery coating processes without the burden of bulky, conventional slot-die coating lines.
Our tools mimic industrial roll-to-roll coating equipment, while fitting into a convenient benchtop form factor and requiring just a few milliliters of solution to begin coating.
Our high-viscosity slot-die configurations are optimized for thick, viscous electrode slurry coatings, while our low-viscosity product line is ideal for exploring scalable solid electrolyte and interlayer coatings on the nanometer scale.
Our simple laptop interface gives excellent control over key experimental parameters and enables easy operation of our tools inside an argon glovebox. Finally, when you’ve optimized your proof-of-concept coating samples, we make it easy to transition to full roll-to-roll coating with our customizable pilot lines.
We offer a wide variety of slot-die coating products that integrate easily into your lab- or pilot-scale R&D workflow. Whether you’re coating electrodes, developing solid electrolytes, working under ambient conditions, or require an inert glovebox environment, we can provide premium slot-die solutions to meet your specific needs.
In this short video, we invite you to join researchers at a leading Danish university in their day-to-day work developing next-gen lithium anode batteries via scalable slot-die manufacturing on the FOM vectorSC benchtop slot-die coater.

Manufacturing modern batteries
Today, we are surrounded by a wide variety of advanced battery chemistries and architectures, including nickel-based, lead acid-based, and lithium-based devices. While all these batteries play an important role in modern life, Li-based devices are considered the most well-known and fastest-growing battery technology. This is due to their rechargeable, lightweight, and high energy density properties. They are widely used in rechargeable electronics such as mobile phones and laptops, and are also the preferred chemistry for powering EV’s and grid storage in the Green Transition. While the exact composition of our green energy infrastructure remains to be determined, batteries are certain to play a role in the future of energy conversion and storage.
The core structure of a conventional Li-ion battery cell consists of an aluminum foil current collector, a cathode layer, a separator saturated with liquid electrolyte, an anode layer, and a copper foil current collector. During cell manufacturing, the anode and cathode layers are coated onto their respective current collector foil, dried, calendered, and eventually sandwiched together with the separator and electrolyte to form a single battery cell. Controllable coating of the anode and cathode layers (also known as “electrodes”) is critical to battery performance. Slot-die coating is therefore often used for this electrode coating process, in order to produce high-quality electrodes with excellent accuracy, at high line speeds with little waste.
Even as battery materials and stack configurations become increasingly sophisticated, low-cost, high-quality manufacturing is certain to remain a constant requirement for mainstream adoption. Developing new battery materials and coating processes for slot-die-based manufacturing can therefore boost the impact, commercial viability, and scaling potential of these new technologies even at the early R&D and pilot-scale stages.
