Custom Lithium Polymer Battery 3.7V

We will evaluate the 3.7V li-polymer battery based on customer requests. It shall include below following aspects:

  1. Size; Industry common algorithm for polymer battery capacity, its capacity ≈ Length * Width * Thick * Ratio (0.1~0.12). After adding PCM, it must fit the final device housing with little space, mostly equipped with 3M double adhesive tape.

  2. Charge & discharge rate: In theory, the smaller the C rate, the better for battery. For example, 1C battery, its generally standard charge & discharge rate 0.2C; fast charge charge & discharge rate 1C. Of course, we can support 3C, 5C even 10C discharge rate of pouch battery.

  3. Capacity. We can produce pouch battery from 30mAh to 2500mAh with different shape. When the material system is LiCoO₂, it will be a little higher than NCM.

  4. Work temperature. Generally, charge temp at 0~45℃; discharge temp at -20~60℃. But we can produce li-polymer battery to 80℃.

  5. Wire & connector components: We mostly use UL3301 UL1007 wires, with JST, Molex, PH, other connectors.

Lithium Battery Process Work Flow

We are a professional lithium battery factory in China. Now we briefly introduce how to produce lithium batteries. It starts from cathode & anode mixing, coating, baking, calendering, automatic slitting & cutting, winding, top & side sealing, electrolyte injection, pressing formation, forming, capacity grading, OCV1 & OVC2, cell to PCB, insulation and shipping. Welcome to contact and ask for the workflow table list.

Select Best 3.7V Lithium Polymer Batteries For Evaluate

We are having around 500 models of li-polymer batteries, or even 7.4V & 11.1V pouch batteries, which can be designed at the early R&D stage of your product.

Custom Li ion Battery for Innovation Products

After we evaluate the polymer battery you need, we will see how to custom lipo batteries for your newly designed electronics product. We can support you from the prototype, samples to mass production. All batteries keep consistent and reliable.

Connectors or Plugs for Lithium Polymer Batterey Choise

  • Most customers tend to select connectors to the mainboard, which can save money and lab costs for soldering. It will be worse in case of lab operation errors.

  • In the right images, we showed the most used connector/plugs. They are JST, Molex, XH, PH, and other models. Each one has different metal spacing of 1.25mm, 1.5mm, 2.0mm, 2.5mm, 2.54mm.

  • We shall also consider the female and male two types. Because both shall be paired. According to our 8 years experience, most batteries are equipped with male plug. 

  • When you have specific unique connector requests, please share the excat model or this URL for refer.
