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...

Polymer lithium cell, called ‘green battery’ is a new generation of lithium-ion battery. In 1999, it started spreading fast into the market. It gains lots of favour from suppliers of digital products like mobile phones, laptops, bluetooth headset series, for its high specific energy, small volume, ultra-thin performance, high safety, no memory effect, long cycle life and other advantages. Famous enterprise like Amperex Technology Limited( ATL for short), whose shipment volume of high-end polymer lithium-ion batteries is in the forefront around the world.   In early 2019, our company generally increased investment of ultra-thin laptop batteries and extended the scale of density factory in July, 2019, updating R&D and manufacturing of li-polymer laptop battery cells. In August 2021, the whole production line of li-polymer cell was moved to Guizhou plant. From then on, our polymer has gained unanimously favourable comments from customers home and abroad, wit...

Cells are widely used for laptop batteries, digital home appliances(like vacuum cleaners), solar energy storage system(like municipal street lights and other outdoor lighting lamps), LED lighting, power tools(like mowers), low-speed EV( like two/three-wheeled electric vehicles), etc.   Therefore, here we will carry on the second part of the lithium ion cell production process introduction and machine equipment display. 7. Winding: Usually the negative pole is long and the positive pole is short while winding.(Pay attention to winding speed and diaphragm tension.)    8. Into the shell: When the coil is put into the steel shell, pay attention to the positive and negative electrode directions, and place a gasket between the negative pole ear and the coil of the cell.(The gasket should not be missed or ectopic.)    9. Groove rolling: Before rolling groove, put a gasket on the positive pole; pay attention to the height above the groove and the total height...
