ENERGY APPLICATION
Battery Electrodes & Nanomaterials
Nanomaterial coatings for energy storage electrodes including lithium-ion batteries, supercapacitors, and solid-state energy storage devices using graphene, carbon nanotubes, and nano-silicon active materials.
The Challenge
Battery electrodes require uniform dispersion of conductive nanomaterials and active particles across current collector foils. Traditional slurry casting methods need excess polymer binder, produce uneven coatings, and waste expensive nanostructured materials like graphene and nano-silicon that are critical for next-generation energy storage performance.
Our Solution
MicroSpray ultrasonic nozzles deposit each nanoparticle in a controlled manner, forming porous, binder-light electrodes with improved ionic access and reduced dead weight. The digitally controlled flow enables exact areal loading (mg/cm²) with minimal overshoot, while the non-clogging design handles water-based and solvent-based battery slurries including complex nanomaterial suspensions.
Why Ultrasonic Spray?
- ✓Uniform nanophase dispersion reduces internal resistance and improves electron percolation
- ✓Porous, binder-light electrodes with improved ionic access
- ✓Precise areal loading control eliminates material overshoot and trimming
- ✓Compatible with water-based and solvent-based battery slurries
- ✓Non-clogging design handles graphene, CNT, and nano-silicon suspensions
- ✓Integrates into roll-to-roll electrode fabrication lines
- ✓Scalable from R&D cells to production-line battery manufacturing
- ✓Homogeneous films prevent hot spots and current spikes, improving cycle life and reducing capacity fade
- ✓Enables protective nanomaterial layers on separators and anodes to suppress Li dendrite growth and electrolyte decomposition
- ✓Supports spray-drying for nano-encapsulated active materials such as silicon-carbon composites
