Spatial ALD in Battery Technology

In a world where reliance on electric vehicles, smart devices and green energy storage is growing exponentially, the need for advanced battery solutions is undeniable. Spatial Atomic Layer Deposition (Spatial ALD) has a crucial role to play in driving innovations within battery technology, with the potential to radically improve core aspects of battery performance – from energy density and reliability to safety.

Roll-to-Roll production lines

Our Spatial ALD technology is atmospheric and compatible with Roll-to-Roll production lines. Together with our German partner Coatema GmbH, we have matured the Spatial ALD technology to roll-to-roll where we ensure that the required layer thickness is obtained within a single pass from reel to reel. Spatial ALD’s unique properties allow us to conformally apply our layer in the deepest pores, making even the most complex 3D surface topology accessible.

  • Improved safety, stability, and sustainability of batteries
  • Increased capacity retention
  • Roll-to-Roll compatibility
  • Adaptability to complex 3D surfaces
  • Tailoring of the complex battery interfaces

Improved solid-state battery quality

Solid-state batteries are the future due to improved safety and longer lifetime. With a solid electrolyte, these batteries are less sensitive to leaks and thermal runaways. While the technology is still under development, Spatial ALD is proving to improve their performance. Applying a solid electrolyte interface (SEI) with Spatial ALD ensures less active ion loss during the first charge cycles, allowing for longer capacity retention. In addition, a Spatial ALD layer can also shorten the SEI forming process; leading to significant reduction in production costs. Lastly, thin layers can reduce internal resistance and optimize ion conductivity, making solid-state batteries more attractive for various applications.

Innovation by working together

Spatial ALD improves battery safety by significantly reducing the risk of short circuits, overheating and fire. By applying ultra-thin protective layers, Spatial ALD increases the chemical stability of the battery components and prevents dendrite formation or transition metal dissolution.

By accurately applying thin functional layers, such as an artificial solid-electrolyte-interface (SEI), to 3D topologies, Spatial ALD allows for the use of energy denser materials by counter-acting high volumetric expansion. This enables more compact battery designs with higher energy storage, crucial in for example the EV market.

Yes, our Spatial ALD technology is compatible with roll-to-roll battery production lines. The Spatial ALD technology can be added to existing production lines to immediately improve the battery performance and reduce production costs by e.g. shortening the solid-electrolyte-interface formation process.

Yes, Spatial ALD can be applied to various battery technologies, including lithium-ion, sodium-ion, solid-state and other emerging battery technologies. The versatility of Spatial ALD makes it a valuable tool for improving various battery types.
