Nickel Metal Hydride No. 5 battery

　　Common defects on the surface of Nickel Metal Hydride No. 5 battery pole pieces

　　Common defects on the surface of Nickel Metal Hydride No. 5 battery pole pieces: 1. Protrusions/agglomeration; 2. Tear/pins; 3. Metal material dirt; 4. Asymmetric coating. Among them: (1) This defect will occur if the slurry is mixed unevenly or the feed speed is uneven or the feed rate is unstable. The agglomeration of adhesive and carbon black conductive agent results in a higher specific composition and lighter weight of the plate. The lack of coating in this defective area is usually caused by air bubbles in the slurry. They reduce the amount of specific species and expose the collection hydrodynamics to the electrolyte of the Nickel Metal Hydride No. 5 battery, thus reducing the volume of the photocatalyst. Metal materials are dirty, materials or metal materials introduced in the natural environment are dirty, and metal materials are harmful to lithium batteries. Large-sized metal particles immediately penetrate the diaphragm, causing a positive and negative short-circuit fault. This is a physical short-circuit fault. In addition, when the metal becomes dirty, the positive potential difference rises after the battery is charged, and the metal melts, diffuses through the Nickel Metal Hydride No. 5 battery electrolyte, and then dissolves in the negative surface, eventually piercing the diaphragm, causing a short circuit failure. fe, cu, zn, al, sn, sus, etc. are the most common dirty metal materials in rechargeable battery processing plants. Uneven coatings such as slurry mixing are not enough. The particle size can easily appear patterned, resulting in asymmetric coating. Even without coating pattern, it will have an impact on the consistency of battery power, volume and safety factors.

　　Online monitoring technologies commonly used in the polarographic film production and manufacturing process include the following aspects: 1. Immediately install an online viscometer to test the rheological properties of the slurry, and test the reliability of the slurry. 2. During the sizing process, X-rays or rays are used to quickly and accurately measure the accuracy of the coating. The measurement accuracy is high, but the radiation source is high, the equipment is expensive, and maintenance is inconvenient. 3. The key technology for laser online measurement of film thickness is to accurately measure film thickness. The measurement accuracy can reach more than 1.0mm. At the same time, it can display accurate measurement information and trend analysis of material thickness. Ternary polymer lithium ion is a lithium-ion battery cathode material. It is used as a precursor for battery cathode materials and ternary composite battery cathode materials. It uses nickel salt, cobalt salt, and manganese salt as raw materials. The nickel-cobalt-manganese ratio can be determined according to the specific requirements. Needs adjustment. Lithium-ion batteries are more powerful than energy, but safety considerations are often questioned. Ternary lithium ion raw materials dissolve at a lower 200 degrees, while lithium phosphate raw materials dissolve at 800 degrees. In addition, the organic chemical properties of the ternary raw material are stronger. It will release oxygen atoms, and the Nickel Metal Hydride No. 5 battery electrolyte will quickly ignite under the action of high temperature, resulting in a chain reaction. The raw materials of ternary lithium are easier to ignite than the raw materials of lithium iron phosphate batteries. According to the characteristics of ternary lithium-ion raw materials that are easy to pyrolyze, manufacturers spend a lot of time in multiple stages such as overcharge maintenance, over-temperature protection, and over-current protection.
