Mn3O4 for lithium-ion batteries was synthesized by suspension oxidation using metallic manganese powder. The effects of experimental conditions, including ammonium chloride concentration, ammonia concentration, solid-liquid ratio, reaction temperature, air flow rate and stirring speed, on the particle size and tap density of Mn3O4 were investigated. The results show that under the optimal conditions, including ammonium chloride concentration of 6 g/L, solid-liquid ratio of 0.3∶1, reaction temperature of 70 ℃, air flow rate of 700 mL/min, and stirring speed of 400 r/min, the as-prepared product is spinel-type Mn3O4 with quasi-spherical particles, which has a D50 particle size of 9.69 μm, tap density of 2.82 g/cm3, specific surface area of 0.399 m2/g, and manganese content of 71.5%. The contents of impurity elements such as S, Fe and Ca therein all meet the requirements in Manganese Tetroxide for Lithium Batteries (YB/T 4736—2019).

采用金属锰粉悬浮氧化法制备了锂离子电池用Mn3O4,探究了氯化铵浓度、氨水浓度、固液比、反应温度、空气流量以及搅拌速率等实验条件对Mn3O4粒径和振实密度的影响。结果表明,在不加氨水、氯化铵浓度6 g/L、固液比0.3∶1、反应温度70 ℃、空气流量700 mL/min、搅拌速率400 r/min条件下,制备的产品为尖晶石型Mn3O4,颗粒为类球形,D50粒径为9.69 μm,振实密度为2.82 g/cm3,比表面积为0.399 m2/g,锰含量为71.5%,S、Fe、Ca等杂质元素含量均满足《锂电池用四氧化三锰》(YB/T 4736—2019)行业标准要求。

Mn3O4 for lithium-ion batteries was synthesized by suspension oxidation using metallic manganese powder. The effects of experimental conditions, including ammonium chloride concentration, ammonia concentration, solid-liquid ratio, reaction temperature, air flow rate and stirring speed, on the particle size and tap density of Mn3O4 were investigated. The results show that under the optimal conditions, including ammonium chloride concentration of 6 g/L, solid-liquid ratio of 0.3∶1, reaction temperature of 70 ℃, air flow rate of 700 mL/min, and stirring speed of 400 r/min, the as-prepared product is spinel-type Mn3O4 with quasi-spherical particles, which has a D50 particle size of 9.69 μm, tap density of 2.82 g/cm3, specific surface area of 0.399 m2/g, and manganese content of 71.5%. The contents of impurity elements such as S, Fe and Ca therein all meet the requirements in Manganese Tetroxide for Lithium Batteries (YB/T 4736—2019).
