Today, Li-ion batteries should be smaller, more powerful, last longer and recharge faster. Producing a Li-ion battery involve many processes, but one of the most important one is spray drying, the technology mastered by GEA Niro.

But making a spray dried cathode or anode powder for Li-ion batteries is not only a question of atomization of the feed material. It is a complete and complicated process involving:

• Feed handling and pumping
• Drying air distribution for optimal drying
• Atomization to produce fine particles of less than 10 microns, and with a narrow particle size distribution
• Collection of the dried fine particle powder with no or little loss to the atmosphere

As the market for Li-ion batteries is growing fast, flexible spray dryers with bigger capacities are needed. They should produce fine pure powders of consistently high quality in order to fulfil the growing performance requirements of Li-ion batteries.

To combine this, GEA Niro has developed the COMBI-NOZZLE™ (patent pending) in different sizes. The nozzle combines the best features of pressure and pneumatic nozzles. The COMBI-NOZZLE™ (patent pending) has been specially developed for materials for Li-ion batteries as it offers unique advantages over other nozzles types:

• Smaller mean particle size
• More narrow particle size distribution
• No oversize particles
• Lower energy consumption

Depending on your capacity requirement for production of materials for Li-ion batteries, we combine one or more of the COMBI-NOZZLE™ (patent pending) in the same spray drying plant. Each nozzle is easy to handle and even interchangeable during production, so no need to stop and clean.

You can now produce continuously and at your required capacity with a spray drying plant from GEA Niro. We have experience with spray drying plants based on nozzle atomization of more than 50 tons/h of liquid feed material which is well beyond any current capacity requirement in the Li-ion battery industry.

 

This includes plants designed for handling either aqueous or non-aqueous (organic solvent) feeds – where nitrogen is used as an inert drying medium. Furthermore, all GEA Niro´s plants are designed to meet international health and safety standards.
