    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 cells Mar 23 , 2022
    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...

  • Density Battery's Tips for Buying Quality Battery Packs and Cells May 14 , 2022
    A battery pack is a collection of cells electrically connected in an array enclosed inside a housing of some kind with a connector and a circuit board attached. If you were to take a battery pack apart, you would find inside a collection of single cells connected together. A cell is a single electrochemical unit, which when connected to other cells, forms the battery pack.  Once you know what you’re looking for, it’s best to consult an expert on how to navigate the battery market. Followings are our top tips for buying quality battery packs. 1. Always use cells and batteries from well-known reputable firms. Battery companies with certified battery packs (UL, IEC, PSE, ATEX, etc.) typically have higher build qualities. Very inexpensive cells and batteries purchased on the internet from companies with no certifications are problematic and can result in a catastrophic event.   2. Be aware that counterfeit batteries exist all over the internet, and many are ...
  • 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...
