Description

technical field

[0001] The invention belongs to the technical field of alumina, and in particular relates to a mixing amphoteric agent of alumina powder and boehmite and mixing equipment. Background technique

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. In the manufacturing process of lithium batteries, the positive and negative electrodes need to be separated by a separator, and the separator needs to be covered with a layer of aluminum oxide as a thermal insulation layer.
