Description

technical field

[0001] The invention relates to the technical field of chemical reaction acidity and alkalinity control, in particular to a reaction liquid pH value detection and addition device used in the lithium battery industry. Background technique

[0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. Lithium-ion battery cathode ternary materials are the focus of current research. During the preparation process, a continuous feeding reaction process is required to improve production efficiency. However, during the continuous feeding reaction process, pH fluctuations are prone to occur, which affects the efficiency of the reaction. However, the manual adjustment of pH is not fast enough and the accuracy is low, which leads to unstable product performance. Contents of the invention

[0003] The object of the present invention is to provide a reactio...
