The battery shows the problem of power loss after welding.CR2430 battery

　　Lithium battery manufacturers talk about the problem of swelling in the battery: 1. Lithium battery swells when charging. When the electric vehicle lithium battery is charged, the lithium battery will naturally swelling naturally, but generally does not exceed 0.1mm, but the electrolyte is divided, the internal pressure increases, and the lithium battery swells.

　　2. Swell up during processing.Generally, the processing abnormal processing (such as short circuit, overheating, etc.) forms an internal heating and excessive electrolyte, and the lithium battery swells.

　　3. Swell up during circulation. When the battery is looped, the thickness will increase with the number of cycles, but the next 50 weeks will not increase in the future. The normal increase of the new lithium battery is generally increased by 0.3 ~ 0.6 mm. form. However, if the thickness of the shell is increased or the internal materials are reduced, the phenomenon of swelling can be appropriately reduced.

　　Then the professional lithium battery also reminds everyone that the position of the welding position is not formed in general. The correct point welding position should be welded at the bottom or marked "A" or " -". The big side cannot be welded. Others are too welded nickel bands. Therefore, a large current point welding must be used, resulting in the internal high temperature resistant tape cannot work, forming a short circuit inside the battery cell.

　　According to the definition, the civil lithium battery can be briefly understood as a battery used by small and medium -sized equipment in our daily life, which is better than table lamp batteries, flashlights, etc.; It provides electrical energy for transportation, weapons, communication and other electrical equipment.

　　From the perspective of information, the demand for new lithium batteries for the production of production data is not high. As long as it can meet the fundamental requirements, that is, there is a power storage function and a certain service life. The surface area and pore rate, better conductivity and thermal conductivity, higher energy density, etc.

　　From the perspective of functional analysis, compared with civil lithium batteries, the comprehensive function of military lithium batteries will be stronger, with longer battery life, higher conductivity talents, better durability and multiplier functions, better anti -unencal temperature Big ability with anti -radiation.

　　Then you must know that the military type of professional lithium batteries not only say that the volume is small and frightened; at the same time, the planning is required to be different from the civil lithium battery. Use it below, and simply provide logistical supply as much as possible.
