The increasing demand for applications within electromobility or stationary energy storage requires the implementation of novel, sustainable and continuous manufacturing processes as well as processes for coating active materials. Aerosol-based methods based on spray drying / spray calcination and spray granulation by powder synthesis and fluid bed technology are presented using selected examples. First results on electrochemical characterisation are shown.

Glatt powder synthesis offers a versatile tool for the development and industrial production of innovative battery materials. The highly flexible technology opens up the possibility of producing and refining anode and cathode materials as well as solid electrolytes in just one step. The key to the effectiveness of this process is the special conditions in the pulsating hot gas flow.
Powder synthesis represents a novel process for the production, activation and coating of battery materials. By using a pulsating hot gas flow with adjustable frequencies and amplitudes, powders of the highest quality can be produced. Solutions to address current shortcomings as innovation drivers for new battery materials.
How future materials become reality with fluid bed technologies and Glatt powder synthesis. Battery materials, 3D printing, phosphorus fertilizers, foodstuffs: thanks to its technology and process-oriented innovation expertise, plant manufacturer and process expert Glatt Ingenieurtechnik is a sought-after development partner in many branches of industry and in the research sector. The Technology Center at the Weimar headquarters is the hub for particle design of future materials. R&D ideas are turned into product samples with flame-retardant properties, for example, and market-ready beverage powders are developed here; the formulation for fertilizer granules with defined release and carbon pellets are being tinkered with.

Value materials: Processes that convert residual materials from wastewater treatment plants into recycled products and endow particles with new properties show how today’s technologies can be used to solve tomorrow’s challenges. Expertise in process development is also in demand in the research and development of future materials such as solid-state batteries or high-performance materials for 3D printing. Previously applicable temperature limits can now be overcome with high-temperature fluid bed systems from Glatt to produce catalyst materials in a single-stage process, for example.

To commercialize next-generation cathode materials a lot of different synthesis methods need to be researched and evaluated regarding the attainable electrochemical properties of the materials on one hand, and the scalability of the process on the other. For the high voltage LiNi0.5Mn1.5O4 cathode material especially the degradation of the material during cycling needs to be investigated for different scales and techniques. LiNi0.5Mn1.5O4 (LNMO) was synthesized using two different methods in different scales: lab-scaled spray drying and pilot-scaled gas pulse drying.

A new thermal process for powder production – Advanced Pulse Powder Technology – is designed to enable targeted particle design. Manufacturers of advanced ceramics can thus achieve unique and customized product properties. (Article in German language)
Glatt Ingenieurtechnik developed a new powder technology that allows powder composition and particle design to be adjusted to meet a customer’s specific application needs. By synthesising the powder in a pulsed hot gas stream, product structures can now be generated that were not accessible with conventional techniques.
Powder production accelerates pulse beat – spray pyrolysis reactor for pigments and catalysts.
Tailor-made – this stands for unique, high-quality and suitable. The Apptec process developed by Glatt for powder synthesis, on the other hand, leaves little room for chance. With a pulsating hot gas stream, this further development of spray pyrolysis enables unerring particle design for application fields such as catalyst and pigment development.
