Liquid injection method of lithium battery

 Lithium batteries have the characteristics of high specific energy, low self-discharge rate, good high and low temperature performance, long charge and discharge life, and no memory effect. At present, it is widely used in products such as mobile phones, notebook computers, digital cameras, electric vehicles, power tools, and new energy vehicles. At present, most manufacturers use the following process to inject electrolyte into the battery: vacuum a certain amount of liquid, pressurize, and discharge the battery. This liquid injection method is a sleeve type liquid injection method, which wastes a lot of labor. , The production efficiency is low, and the risk of side leakage of the sleeve is prone to occur. At the same time, because this injection method uses quantitative injection, the injection volume of each injection is the same, and then the more the injection times, the more to the back, It is more and more difficult for the battery to absorb the electrolyte, causing the electrolyte to easily enter the vacuum system, resulting in waste of electrolyte, corrosion of the injection equipment, and increasing production costs.

  In order to solve the shortcomings of the existing technology, the lithium battery automatic production line invented by Mikrouna provides a fully automatic scanning-injection-weighing-replenishment-sealing operation to achieve high-efficiency and completely unmanned automatic production, greatly saving labor costs Improve production capacity, product quality and yield, and maximize the benefits for customers.

  The technical effect of the automatic production line of Mikrouna's lithium battery: it can improve the efficiency of the injection of lithium batteries, the qualification rate of the injection and the accuracy of the injection; it can also reduce the waste of electrolyte, reduce the corrosion of the injection equipment, and reduce the production cost; Productivity.
