  • Cylindrical 18650 lithium-ion cells Dec 17 , 2021
    Presently, 18650 batteries are the earliest, maturest and the most stable, wildly used for varieties of electronics. Tesla, famous manufacturer of electric cars from USA, decided to choose 18650 batteries after testing various batteries in R&D, considering about two essential factors, consistence and safety. Popular Panasonic and LG are 18650 battery suppliers designated by Tesla.   The chemical materials of our 18650 cells are mainly NCM. The partner of anode materials is well-known in China. Comparing with LFP and Lead-acid batteries, NCM batteries’ best advantage is having higher energy density and having a balance in capacity and safety, whose comprehensive performance are excellent, like high platform voltage, no memory effect, small internal resistance, small self-discharge and long cycle life.   Here are multi-kinds of cells we are producing, and they are 18650 3.7V 1800/2000/2200/2500mAh cells, with 0.5C/3C/5C/10C/15C working discharge. Our daily turnover ca...
  • Density Battery Customization Process of 18650 Lithium Battery Pack Apr 29 , 2022
    The customization process of 18650 lithium ion battery pack is customized according to the actual product requirements. The following process should be noted: 1.If customer knows exactly what would be needed, battery can be customized as per provided lithium ion battery size, electrical performance requirements, output requirements and functional requirements. 2.If customer is confused about what would be needed, ideal functional requirements, working hours, product power, appearance shape, etc. need to be provided to factory to customize battery. 3.After confirming functional requirements of products, samples will be developed by professional battery engineers based on actual situation. 4.When appearance, function and other details of the sample battery are confirmed, the manufacturer will reply a specific delivery time to customer based on estimated material situation. 5.After both customer and factory confirm the delivery time of customized battery, a contract will be signed by both...

  • The Lithium ion Battery Cells Manufacturing Process Jul 27 , 2022
    What Is The Manufacturing Process of Lithium-ion Battery Cell? The first step of Cylindrical 18650 Lithium-ion Cells production: 1.Pulping: The advanced automatic feeding system help feed automatically, without direct contact of manual, and ensuring the high cleanliness and pollution-free of materials.(The feeding sequence, mixing speed and mixing time shall be in strict accordance with the battery process standards)   2.Coating: The coating thickness is accurate up to ± 2um / surface. Meanwhile, the coating density is detected by β -ray on-line to ensure the standardization of products from the aspects of thickness and density.(Quality of cells depend on coating by 60%, like, whether there are scratches, particles, bubbles, dark marks, etc)     3.Drying: Oven is 18m. Coating speed is 8m / min and baking time is 2.25 min. (Maximum baking temperature should not exceed 140 ℃)     4.Rolling: Rolling accuracy can be co...
