We’re pleased to share that SparkNano has been included in Battery News‘ latest publication ‘2024 Battery Atlas Highlights – Nine European Battery Market Sectors‘ which reflects the current involvement of cell manufacturers, module and pack producers, suppliers of equipment, and battery active materials as well as recycling companies and battery test centers.

‘ The 2024 Battery Atlas covers nine different topics: Battery Cell Manufacturers, Module and Pack Manufacturers, Battery Equipment Suppliers, Active Material Suppliers, Recycling Companies, Battery Test Centers, Battery Quality Assurance Companies, Passive Battery Cell Component Companies, and Second-Life Battery Companies. Thus, this second edition provides an update on the subjects of its predecessor and at the same time is an addition to the initial Battery Atlas. Therefore, it covers a large part of the battery’s life cycle, starting with the active and passive cell components up to the recycling or second life of battery cells. SparkNano is listed among innovative equipment suppliers.

Lithium-ion batteries require very thin protective coatings, often referred to as passivation layers, to prevent degradation of the electrodes, which can lead to quick deterioration of the cycle life of the battery. Given the typically high porosity of these electrodes, Atomic Layer Deposition (ALD) emerges as one of the most effective methods for applying these protective films. ALD produces films that are inherently uniform and conformal, even at very low thicknesses. Battery manufacturing, however, requires large-scale, high-throughput mass production methods, such as roll-to-roll processing, to ensure cost efficiency. This poses a significant challenge for conventional Atomic Layer Deposition (ALD) when high-throughput processing must be combined with highly porous substrates, as longer exposure and purge times are anticipated.

In conventional ALD, precursors are sequentially introduced to create a monolayer of material on a substrate. Spatial ALD enhances this capability by introducing a spatial separation between the precursor and the co-reactant. In other words, rather than depositing the precursors directly onto the substrate in a sequential manner, they are physically separated in space. This innovation enables faster and more flexible deposition processes, addressing critical needs in battery manufacturing.

About is an industry newsletter service that regularly reports on all important developments in the field of lithium-ion batteries. The aim is to bring the German and international battery industry even closer together in order to meet the great information needs of many companies and their employees.

About SparkNano

SparkNano offers Spatial ALD nano-coating tools suitable for various applications, ranging from research and development (R&D) to pilot line production. The Labline series and the Omega cater to different production scales, each featuring a modular design that provides flexibility for both thermal and plasma-enhanced Spatial ALD processes, as well as maskless patterned deposition capabilities. The Labline series, specifically tailored for pilot line production, comes in two sizes accommodating substrates up to 6 inches and 12 inches, respectively. The Labline 6′′ and Labline 12′′ versions include free envelopes of 150 mm x 150 mm and 300 mm x 300 mm, respectively, suitable for accommodating any flat substrate with a substrate-specific holder. The Omega roll-to-roll series is designed for larger-scale manufacturing, supporting standard webs ranging from 300 to 1000 mm in width, with a remarkable web speed of up to 60 m/min. Substrates with a foil width of 300 mm up to 1000 mm are supported, and the maximum foil thickness depends on the material properties in combination with the minimal and maximal web tension and drum diameter.
