Battery & Redox Flow Coatings
Thin-film surface solutions for stable, efficient battery and redox flow systems.
Thin-film coatings that stabilize battery and redox flow system performance
Modern batteries and redox flow systems depend on stable interfaces to deliver consistent performance and long service life. Electrode surfaces and metallic components operate in an electrolyte environment that can trigger reactions.
These reactions can drive structural changes, increase contact resistance, and accelerate degradation. Thin-film coatings offer a targeted way to protect and enhance these interfaces, control ion and electron transport, and limit parasitic reactions that reduce efficiency and stable operation.
With nanoscale precision, sputtered layers help prevent corrosion, reduce interfacial losses and support the reliability needed in advanced battery architectures and large-scale redox flow storage.
Unstable interfaces limit battery and redox flow performance
Rechargeable batteries and redox flow systems face degradation driven by reactions at the interface between electrodes and electrolytes. Metals can corrode, conductive surfaces can lose activity and insulating layers can form, raising resistance and reducing cycle life. In compact battery designs, volume changes and weak adhesion can cause cracks or delamination, while in redox flow batteries the acidic electrolyte accelerates corrosion of metallic bipolar plates and current collectors.
OEMs and system developers need surface solutions that stabilize these interfaces, limit side reactions and maintain conductive over long operating periods without increasing system complexity or cost.
