Many times, when people go out, they will encounter the situation that the mobile phone is out of power and forget to bring the power bank and charger, which brings certain inconvenience to life. If there is such a piece of clothing, it looks no different from ordinary clothes, but it can wirelessly charge mobile phones and other electronic devices. Isn’t it exciting?

Polymer lithium ion batteries can be divided into three categories: 1. Solid polymer electrolyte lithium ion battery. 2. Gel polymer electrolyte lithium ion battery. 3. Lithium-ion battery with polymer cathode material. Advantages of lithium polymer battery: 1. Good safety performance 2. The thickness is small and can be made thinner 3. Lightweight 4. Large capacity 5. Small internal resistance 6. The shape can be customized 7. Good discharge characteristics 8. Simple protection board design

Introduction to the types of lithium batteries Classified by battery shape Classified by working temperature Classified by electrolyte state Classified by use category Classified by cathode material

There are many reasons for the explosion of 18650 lithium-ion batteries, mainly three. 1. Overcharged 2. Short circuit 3. High temperature

Earlier power banks gave most users a big and heavy impression, but today's power banks are small, especially shared ones. Friends who have used it will feel very light. This is the credit of the polymer lithium-ion battery. In fact, due to the emergence of polymer lithium-ion batteries, many electronic products can perform better, such as TWS Bluetooth headsets and special small electronic devices. Unlike a few years ago, there are fewer and fewer 18650 lithium-ion batteries used in mobile power sources. Is it really eliminated? In addition to volume and weight, what is the difference between polymer lithium ion battery and 18650? This is what we are going to talk about today.
