Proven industrial reliability
Designed for modern battery architectures
As EV batteries transition to higher voltages and denser packaging, coating precision becomes critical.
Xaar’s inkjet approach enables:
- Uniform coating thickness across complex geometries
- Reliable coating of prismatic and cylindrical cells
- Improved layer thickness consistency compared to spraying or film-based methods
This digital approach not only improves performance but also simplifies manufacturing and supports scalable production.
Advanced inkjet technology for functional coatings
Xaar combines multiple core technologies to deliver consistent, industrial-grade performance:
Ultra-High Viscosity Technology
- Jetting fluids up to 100 cP enables advanced coating chemistries with improved durability and insulation
High Laydown Technology
- Deposits thick functional layers in a single pass so reduces process steps and improves efficiency
TF (recirculating) Technology
- Continuous fluid flow and prevents clogging and enables reliable jetting of challenging materials
AcuChp Technology
- Delivers uniform drop size across printheads ensuring consistent coating thickness and performance
SureFlow self-cleaning
- Maintains nozzle health and uptime and minimises operator intervention
Purpose-built printheads for battery coating
Xaar is the first inkjet company to develop printheads specifically for EV battery coating, setting a new benchmark in the industry.
