Spray drying has been applied for many years for production of fine powders of high quality for various types of batteries. Over the years, the demand to energy density and performance of batteries from new applications has led to the development of new generations of batteries, including secondary lithium-ion batteries. These batteries are foreseen to play an important role in the electric vehicle market, which is predicted to grow significantly in the coming years. For this reason, there is an intense race among leading manufacturers worldwide for developing proprietary Li-ion batteries with superior performance characteristics. This includes development and proper manufacture of cathode materials, such as lithium iron phosphate (LiFePO4), and spray drying will play a leading role in realizing the full industrial potential of these materials.
