Description
Technical Field
The invention relates to the technical field of batteries, in particular to a battery structure for injecting liquid from the bottom and a battery liquid injection method.
Background
For the battery liquid injection technology, the process of injecting the liquid electrolyte into the battery from the liquid injection port is generally based on controlling the quantity and injection time of the liquid electrolyte, and the main purpose is to form an ion channel, so that enough lithium ions can migrate between the positive electrode plate and the negative electrode plate in the charge and discharge process of the battery, and reversible circulation is realized.
At present, those skilled in the art know that the common liquid injection mode is mainly divided into two types, one is to directly inject liquid through a liquid injection hole, which is also the most mainstream mode, and the other is to put a battery into the electrolyte to allow the electrolyte to permeate into the battery; the method adopts a liquid injection hole liquid injection mode, and can be divided into single liquid injection and multiple liquid injection according to the liquid injection amount (different from battery structure and batch to batch), and the measures for promoting the infiltration are different from each other, wherein the single liquid injection method promotes the infiltration of electrolyte in a battery core through repeated pumping and pressing, the multiple liquid injection method promotes the infiltration of electrolyte in the battery core through a pressurizing mode, and the immersed liquid injection does not have the measure for promoting the infiltration.
After analyzing the battery liquid injection technology of the same kind in the past, the research and development personnel in the technical scheme find that the battery liquid injection technology in the past is influenced by factors such as a liquid injection mode, a liquid injection position, a battery self structure, a sealing means, a battery core infiltration degree and the like, so that an ideal liquid injection effect cannot be obtained, and the specific analysis is as follows:

Secondly, for many metal-packaged battery structures, the upper surface of the battery structure is usually provided with a molybdenum rod and is provided with a steel ring and the like, wherein the molybdenum rod has high melting point, good heat conductivity and low thermal expansion performance and is commonly used for manufacturing electrodes, if a liquid injection hole is additionally arranged around the molybdenum rod or the steel ring or a sealing structure arranged on the upper surface, obviously, the smoothness of liquid injection of the battery can be influenced, the stability of the structure of the battery can be damaged to a certain extent, the service life and the application performance of the battery are difficult to ensure, and the defect that the liquid injection hole is additionally arranged from the upper surface is common at present.
Thirdly, as known from the above analysis, if a liquid injection mode of taking out the battery cell and putting the battery cell into the electrolyte and allowing the electrolyte to permeate into the battery is adopted, the liquid injection mode is also common in the field, but the mode belongs to a mode of taking out the battery cell and independently operating, and obviously, obvious disadvantages exist in the aspects of liquid injection efficiency, labor hour cost, ensuring the structural rigor of the battery and the like, and the continuity and fluency of the liquid injection operation of the battery are not facilitated.
Therefore, the technical means adopted by the current battery injection is not suitable for adopting an injection mode of independently taking out the battery cell injection, but also is not suitable for adopting an injection mode of injecting the battery cell injection downwards through the injection hole arranged on the upper surface.
