During the preparation of lithium battery anode and cathode slurries as well as solid electrolyte slurries, powder agglomeration and microbubbles inside slurries will cause coating pinholes and electrode sheet defects. SIENOX planetary stirring and defoaming machine, special equipment for lithium battery material R&D, provides an integrated mixing and defoaming solution for the development of battery slurry samples.

Adopting a paddle-free mixing structure with planetary rotation and revolution, the SIENOX planetary stirring and defoaming machine breaks up agglomerated particles of active materials and conductive agents by centrifugal force. Sealed cups reduce contamination from metallic impurities. The supporting vacuum system simultaneously extracts deep microbubbles inside the slurry. Mixing and defoaming are finished in one step, greatly shortening the sample preparation cycle. The machine supports multi-stage program setting, allowing low-speed pre-mixing, high-speed dispersion and vacuum holding processes to simulate the graded stirring logic of lithium battery slurries. An optional temperature control module regulates slurry temperature and suppresses solvent volatilization.

It supports dry powder pre-mixing mode, which enables dry mixing and degassing of active materials and conductive agents before adding solvents for wet mixing. One main unit handles both dry powder pre-mixing and wet slurry preparation. Clamps for large-volume cups are available for pilot small-batch slurry trial production. Built-in data logging and export functions help researchers record preparation parameters of each batch and compare electrochemical test results. Equipped with a comprehensive safety protection system, it meets the operating standards of lithium battery R&D laboratories.

SIENOX offers free sample testing for lithium battery slurries. We adjust graded stirring and defoaming processes on the planetary stirring and defoaming machine to evaluate slurry dispersion and defoaming performance. Designed for formula R&D samples and pilot trial production of lithium batteries, the equipment serves battery material manufacturers and research institutes for new-generation slurry development. With integrated mixing and defoaming performance, SIENOX planetary stirring and defoaming machine helps lithium battery researchers quickly prepare uniform, low-bubble slurry samples and accelerate the R&D iteration of new battery materials.
