Energy Storage Industry Enters a Golden Era of Development

A recently released white paper on energy storage by TÜV Rheinland shows that China occupies an important position in the global energy storage market. Last year, China contributed approximately half of the world's newly installed energy storage capacity, with the domestic new-type energy storage installed scale approaching 150 GW. According to forecasts, by 2030, China's new-type energy storage installed capacity will conservatively reach 371 GW.

Driven by this wave of energy storage development, all links in the lithium battery manufacturing industry chain are embracing new development opportunities. Among them, spray drying, as a key process link in lithium battery material production, directly affects the particle size distribution, particle sphericity, and batch-to-batch consistency of cathode materials, making it a crucial factor determining battery performance.

The Core Value of Spray Drying Technology

In the preparation process of lithium battery cathode materials, spray drying is responsible for converting precursor solutions into powder particles with specific particle sizes and morphologies. The level of process control at this stage is directly related to the material's tap density, specific surface area, and electrochemical performance.

Specifically, spray drying requires balancing multiple process parameters: the atomization method determines the initial size and distribution range of droplets; inlet air temperature and air volume affect the drying rate and particle morphology; and feed speed is directly linked to production capacity. Fluctuations in any single parameter can cause quality differences between batches, which in turn affects the consistency performance of downstream batteries.

As energy storage batteries continue to evolve toward larger capacity and higher safety, battery enterprises are imposing stricter control standards on indicators such as particle size distribution, tap density, and moisture content of cathode materials. This places higher demands on the process precision and operational stability of spray drying equipment.

From Lithium to Sodium: Forward-Looking Layout for Emerging Technology Routes

The rapid growth of the energy storage industry is driving technological upgrading in the upstream equipment manufacturing sector. As a key link in material production, the technological progress of spray drying equipment is closely tied to the development pace of the lithium battery and sodium battery industries.

Notably, in addition to supporting the capacity expansion needs of the energy storage battery industry, Xinpu Drying's spray drying equipment has already carried out forward-looking technology reserve work for emerging technology routes such as sodium-ion batteries. The preparation process of sodium battery cathode materials differs from that of lithium batteries, posing new challenges for the adaptability of the drying process. By adjusting the atomization system and temperature control strategy, Xinpu Drying provides process support for the mass production of sodium battery materials.
