Analysis of the basic structure and advantages of square lithium batteries

A typical prismatic lithium battery, its key components include: machine cover, case, positive plate, negative plate, winding or rewinding machine composed of diaphragm, insulating layer components, safety parts, etc. OSD overcharge protection device. The basic structure of the grid rechargeable battery is a typical grid lithium battery. Its key components include: a cover, a casing, a positive electrode sheet, a negative electrode plate, a winding or rewinding machine composed of a diaphragm, an insulating layer, and safety components. A metal material layer, such as a copper sheet, is added to the outermost layer of this type of core. When a needle stick occurs, part of the large current caused by the position of the needle quickly reduces the current amount of the company's total area according to the large-scale metal sheet, preventing some over-temperature and alleviating the occurrence of uncontrollable heat of the rechargeable battery. Processing and manufacturing of electronic component products and application technologyA method for processing and manufacturing square aluminum shell lithium battery cells fully automatically into the shell A method for processing and manufacturing square aluminum shell lithium battery cells fully automatically into the shell This utility model patent announces a This is a square aluminum shell lithium battery cell fully automatic shelling machine, including: aluminum shell transportation equipment installed in the middle area of u200bu200bthe cabinet countertop during work, automatic blanking equipment installed at the left end of the cabinet countertop during work, and its control equipment. There is an intermittent shell moving organization on the left side of the slide rail support frame at the right end of the middle cabinet countertop. The bottom is equipped with multiple shell precise positioning clip sets, which are opposite to the fully automatic shell filling equipment, and are equipped with lithium battery core clips. Directly below the delivery organization, there is an output port for aluminum transportation equipment, and an intermittent housing movement organization is set on the left side of the sliding rail support frame equipped with aluminum housing for the organization. The lower side is equipped with a fully automatic blanking equipment. The multiple name type into the shell precise positioning clamp group. The advantages of the square lithium battery: the reliability of the square lithium battery package is high; the relative weight is lighter, and the specific energy is higher; the structure is simpler and the expansion is more convenient. It is the key choice to increase the specific energy by increasing the single volume at this stage; the single volume is large, Then the system software is simpler and can be tested one by one; another benefit of the simple system software is stronger reliability. Disadvantages Because square lithium batteries can be qualitatively analyzed according to product specifications, there are thousands of models and specifications on the sales market. Because of the many models and specifications, the production process cannot be unified, the processing and manufacturing automation technology level is not high, and the individual differences are very large. In the practical application, there is a problem that the service life of system software is far less than the single service life. According to the statistical analysis of Gaogong's lithium battery, the soft-packed battery pack is 20% lighter than the aluminum-packed lithium battery pack of the same volume, and the volume of the aluminum-packed lithium battery pack of the same specification is 50% higher. Although the supplementary posts in 19 years are not optimistic at this stage, there is no doubt that the amount of subsidy is closely related to the specific energy of rechargeable batteries, and soft pack batteries have very big advantages in these aspects.
