Abstract: With the booming development of the new energy vehicle market, lithium-ion battery serves as the core power source, its performance improvement has become the key point. The application of vacuum distillation furnaces in the new cathode materials for lithium-ion batteries demonstrates significant advantages. By analyzing the challenges faced by lithium-ion battery cathode materials, the technical principles and benefits of vacuum distillation furnaces are expounded, covering key technologies such as high-temperature evaporation systems, temperature control in the transition zone, rotary cooling constant-temperature collection system, and vacuum maintenance system. The results show that vacuum distillation furnaces can efficiently produce high-quality silicon monoxide (SiO) cathode materials, significantly enhance the material performance consistency and boost the energy density of lithium-ion batteries. Moreover, the furnace has the potential for large-scale production, which can reduce production costs and meet the market demand for high-performance lithium-ion batteries in new energy vehicles.
