Abstract

The invention relates to an electrolyte tubular reactor, which comprises reaction tube. A reaction cavity is arranged inside the reaction tube. The body of the reaction tube is slantly arranged with one end higher and the other end lower. The higher end of the reaction tube is provided with multiple raw material feeding inlets used for adding different electrolyte preparation materials, and the lower end of the reaction tube is provided with a discharge port used for discharging an electrolyte. By the adoption of the reactor of the invention, continuous production of feeding, stirring and discharging can be realized. The process time is short, batch quantity is small, and mass range of the processed electrolyte is wide. 200 kg to 20 tons of the electrolyte can be produced in the same reactor, and production residue is less. Quality stability of the product is greatly enhanced. A mixing plate inside the reactor can change speed and / or direction with a rotation shaft. Internal materials are uniformly mixed, and EC is not easy to freeze when added.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an electrolyte tubular reactor and a reaction method. Background technique [0002] When a large amount of production is required for the production of electrolyte using the current reactor, multiple batches and multiple reactors are often required for production, and continuous production of feeding, stirring, and discharging cannot be realized. Only the first feed, then stirring, and then stirring for a period of time Discharge. Using a specific reactor, a reactor can only produce specific mass parts of electrolyte. And the use of existing reactors has relatively serious residual problems. [0003] The solvents of lithium-ion battery electrolytes currently on the market include DMC (dimethyl carbonate), DEC (diethyl carbonate), EMC (ethyl methyl carbonate), EC (ethylene carbonate), etc., EC is in each formula A substance that will always be contained in the system,...
