What are application of 3.7V lithium pouch batteries?

Most of the current polymer batteries are soft pack batteries, using aluminum plastic film as the outer shell. When the organic electrolyte is used inside, the liquid will not explode even if the liquid is hot. Because the aluminum plastic film polymer battery adopts solid or gel state without leakage, but expansion. In terms of shaping, polymer batteries can be thinner, arbitrarily shaped and arbitrarily shaped. Therefore, polymer lithium batteries are widely welcomed by various manufacturers.

3.7V lithium-ion polymer batteries are commonly used in a broad spectrum of applications, including:

  • Headlamp, LED headlight, headlight, flashlight, mining light, outdoor light.
  • Neck massager, shoulder massager, smart back massage, muscle vibration machine.
  • CCTV camera, video camera, digital camera, surveillance system, analog camera.

FAQ of li-polymer batteries

  • What is Li-polymer Battery?
    Lithium polymer battery (Li-polymer), also known as polymer lithium ion battery, is a chemical battery. Lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of different shapes and capacities to meet the needs of some products. The theoretical minimum thickness can reach 0.5mm.

  • Will polymer lithium batteries explode?
    Polymer lithium battery is a kind of lithium battery product made of flexible packaging and polymer electrolyte. It will not explode during normal use and storage unless it is short-circuited due to artificial damage.

  • Which is better and more durable, 18650 lithium battery or polymer lithium battery?
    Compared with the 18650 battery of the same volume, the polymer lithium-ion battery has a larger capacity, which is more than 30% higher. If you want to buy a large-capacity mobile power supply, you’d better choose a polymer battery, which is thinner and more portable. Mainly depends on the field of application.

  • Lithium polymer batteries will also produce bulges, so how to deal with this?
    When the polymer lithium battery bulges, it can be repaired by freezing. There is also a repair method for polymer lithium battery bulge is to turn on the battery and discharge it or connect a resistor.
