About the formation type of lithium battery? Lithium battery formation is the first charging process of the battery after the lithium battery is injected. At the same time, a side reaction occurs between the lithium salt and the electrolyte, and a solid electrolyte interface (SEI) film is formed on the negative electrode side of the lithium battery. This layer of […]

Notes on code printing of lithium battery? Precautions for lithium battery printing: 1. Observe whether the conveyor belt of the lithium battery inkjet printer shakes or runs skewed, and if necessary, the inkjet equipment engineer maintains and corrects it. 2. Clean the conveyor belt and confirm the model and code type of the lithium battery cell that has been sprayed. […]

Requirements for printing code of lithium battery? Lithium battery coding requirements: 1. There should be no sharp objects such as scissors, steel rulers, and pens on the desktop. 2. The operator of the lithium battery inkjet printer needs to check whether the ink and additives of the inkjet printer are sufficient every time the shift is started. When the ink […]

About the manufacturing batch number? The production batch number of each production manufacturer is different. Probably the specific content is the year and month of manufacture.   Knowing the production batch number code of the manufacturer can know when the battery was manufactured. In case of confusion with old batteries.

About capacity and voltage printing? The capacity and power will be marked on the battery. Such as: 1800mAh, 2000mAh, 2200mAh, 2400mAh, 2500mAh, 2600mAh, etc. common to 18650 batteries. These are the capacity of the battery, and some manufacturers will also spray the power corresponding capacity on the battery.

About material identification code? Generally, it will be on the top of the battery jet terminal, such as ICR, IMR, NCR, IFR, LTO, etc. ICR: The cathode material is lithium cobalt oxide. IMR: Lithium manganese oxide is used as the cathode material. NCR: Nickel cobalt lithium manganese oxide (commonly known as ternary) is used as the positive electrode material. IFR: […]

About the drying principle? Enter the drying room to remove moisture, and let it stand for some time in the drying room. The operation of removing moisture from solid materials by vaporizing water or other solvents by heating and removing the generated steam. A drying room is a room that uses a dehumidifier to reduce the air humidity in the […]

About the role of plasma cleaning? The ion cleaning method can effectively remove dirt, dust and other substances on the end face of the battery pole, and prepare for battery welding to reduce bad welding. 1. Ashing the surface organic layer The pollutants are partially evaporated under vacuum and instantaneous high temperature, and the pollutants are crushed by high-energy ions […]

About plasma cleaning? Plasma cleaning is a dry cleaning that relies on the “activation” of active ions in the plasma to remove stains. This method can effectively remove dirt, dust and other substances on the end face of the pole of the battery cell, prepare for battery welding, and reduce bad welding. Cleaning steps: place the battery in the battery […]

Regarding welding appearance requirements? Welding Appearance: No void, welding scorching, welding penetration, welding slag, no electrode dome, fracture Super-welding technology and requirements of lithium-ion battery shell: 1. The packaging and connection of the shell generally adopts ultrasonic plastic welding. 2. Working principle: The high-frequency vibration of ultrasonic waves causes friction between the upper and lower shells, and the local temperature […]
