About the welded cap? The lithium battery cap is a component of the lithium battery, which acts as a positive conductive terminal on the lithium battery, acts as a safety valve, and also provides a battery sealing function. Lithium battery cap includes top cover, rubber ring, explosion-proof diaphragm, aluminum sheet/nickel sheet and orifice plate. The top cover is installed on…

About the pouch battery? Soft-pack lithium-ion battery packs have better safety performance. light weight The weight of the pouch battery is 40% lighter than the steel-cased lithium battery of the same capacity, and 20% lighter than the aluminum-cased battery. large capacity The capacity of the soft-pack lithium-ion battery pack is 10-15% higher than that of steel-cased batteries of the same…

About hard case batteries? Hard-pack lithium-ion batteries are subdivided into cylindrical and square. The difference from the soft-pack lithium-ion battery pack is that the external packaging shell is a metal shell, so a hard-pack lithium-ion battery of the same volume is much heavier than a soft-pack lithium-ion battery. Cylindrical lithium battery Cylindrical lithium battery is a kind of lithium ion…

About the role of battery baking? In the multiple production processes of lithium batteries, the positive and negative electrodes, batteries and batteries are vacuum baked several times to remove the moisture as much as possible. Since the moisture content in the lithium battery must be strictly controlled, moisture has a great impact on the performance of the lithium battery, including…

About the reserved liquid injection hole? The process of injecting the electrolyte (lithium hexafluorophosphate, etc.) into the battery according to the required amount by reserving the injection hole is divided into primary injection and secondary injection. One-time liquid injection is the first liquid injection.   After the liquid is injected, the electrolyte is infiltrated into the pole piece through the…

About laser welding? The reasonable selection of welding methods and processes in the battery production process is very important, which will directly affect the production cost, quality and safety performance of the battery. As an advanced new welding method, the battery laser welding process is being widely used. Principle of battery laser welding Battery laser welding is to focus the…

About the battery case material? The main function of the battery pack case is to carry the battery pack. Protect from damage from external bumps, shocks and extrusions. 1. Steel shell The steel battery pack shell is the most primitive power battery pack shell material, which is generally welded by cast steel plates. 2. Aluminum shell The battery pack is…

About lithium battery steel case? As a key component of the battery system, the battery case plays a role in fixing and fully sealing the internal electrochemical system. Steel battery pack shells are generally welded by cast steel plates. High strength, high rigidity, heavy weight, the surface needs anti-corrosion treatment, so that it still has a good anti-corrosion effect under…

About the machine vision alignment detection of lithium battery pole pieces? Winding degree monitoring requirements: 1. The distance from the diaphragm to the positive electrode. 2. The distance from the diaphragm to the negative electrode. 3. The distance from the positive pole to the negative pole. 4. Detection accuracy ±0.1mm. Defect detection: Shell bottom: pits, white spots, iron chips, bumps,…

About the machine vision alignment detection of lithium battery pole pieces? In the winding process of lithium battery production, the positive and negative electrodes are placed in the separator.   The negative electrode needs to exceed the positive electrode by a certain margin in the width direction, and the separator exceeds the negative electrode by a certain margin.   The…
