To overcome the problems existing in the preparation of lithium tetrafluoroborate using the current aqueous solution method, this invention provides a method for preparing battery-grade lithium tetrafluoroborate and a lithium-ion battery. The preparation method includes the following steps: adding and dispersing boric acid and lithium salt in an alcohol solvent, while simultaneously adding hydrofluoric acid dropwise to react and obtain a reaction solution containing lithium tetrafluoroborate. The reaction solution is then subjected to azeotropic removal of water using the alcohol solvent to obtain crude lithium tetrafluoroborate. The crude product is then purified by removing the alcohol solvent to obtain battery-grade lithium tetrafluoroborate. This invention also provides the application of the above preparation method in lithium-ion battery electrolytes. The method for preparing lithium tetrafluoroborate provided by this invention introduces an alcohol solvent during the reaction process, which reduces the complexation of the product with water in the traditional aqueous solution method. This significantly improves the yield and purity of the obtained lithium tetrafluoroborate, and simultaneously meets the stricter requirements for the content of impurities such as water, acid, and alcohol in battery-grade lithium tetrafluoroborate, thus facilitating industrial application.

The application discloses an online mixing-free variable-viscosity high-resistance-slowing acid, and provides an online mixing-free variable-viscosity high-resistance-slowing acid system, wherein the performance of acid liquid can be changed by changing the adding amount of the agent, and the acid liquid does not need to be prepared in advance. The film-forming agent can form an adsorption film on the surface of rock, and the adsorption film blocks the contact between H+ and rock, thereby slowing the acid-rock reaction rate. The application also has multiple composite slow-down performances, and combines the characteristics of foam slow-down acid and gelling slow-down acid. Through the thickening and slowing down of the multiple-effect agent and the blocking and slowing down of the film-forming agent, the acid-rock reaction rate is greatly reduced under the double slow-down effect of the two. In addition to the good thickening effect, the application also has excellent resistance-reducing performance, and one agent is used for multiple purposes to reduce the adding amount and type of the additive. Meanwhile, the resistance-reducing rate of the system reaches more than 85%, which is much higher than the 70% of the traditional system.
