Elucidation of important differences between polymer lithium-ion batteries and lithium-ion batteries

The difference between polymer lithium ion battery and lithium ion battery Polymer lithium ion battery generally refers to polymer lithium ion battery. According to the difference of electrolyte materials used in lithium ion battery, lithium ion battery is divided into liquid lithium ion battery and polymer lithium ion battery or Plastic lithium ion battery. The concept of lithium-ion batteries is used very frequently. With a little hope, we will find that there are three different types of concepts: broad sense, narrow sense, and narrow sense. Lithium-ion batteries in a broad sense include lithium primary batteries and lithium-ion batteries; because lithium-ion batteries are more widely used than lithium primary batteries, lithium-ion batteries generally refer to lithium-ion batteries in a narrower sense; there are two types of lithium-ion batteries. Classification: polymer lithium ion battery and liquid lithium ion battery, because the mass is larger and the application is more liquid lithium ion battery, so the narrow sense of lithium ion battery refers to liquid lithium ion battery, and polymer lithium ion battery is also called Lithium polymer batteries are commonly referred to as polymer batteries. 1. The basic difference is that the raw material polymer battery refers to the use of polymer materials in at least one of the three major components of the positive electrode, the negative electrode or the electrolyte. Macromolecules mean large molecular weights. The corresponding concept is small molecules. Macromolecules have high strength, high toughness and high elasticity. The polymer materials currently developed for polymer batteries are mainly used for positive electrodes and electrolytes. 2. Different shaped polymer lithium-ion batteries can be thinned, arbitrarily shaped, and arbitrarily shaped. The reason is that the electrolyte can be solid or colloidal rather than liquid. Lithium ion batteries need to recycle the electrolyte, which requires a robust The casing serves as a secondary package to contain the electrolyte. Therefore, this also adds a part of the weight of lithium-ion batteries. 3. In terms of safety, most of the current polymers are soft-pack batteries. The aluminum-plastic film is recycled as the outer shell. When the organic electrolyte is recycled inside, the liquid will not explode even if the liquid is hot, because the aluminum-plastic film polymer battery is recycled in solid or colloidal state. There is no leakage, just a natural separation. However, any work is not absolute. If the instantaneous current is large enough to produce a short circuit, it is not impossible for the battery to spontaneously ignite or burst. The quiet and chaotic generation of mobile phones and computers is mostly caused by this environment. 4. Battery cell voltage Because polymer battery recycles polymer materials, it can be made into a multilayer combination in the battery cell to reach high voltage, while the nominal capacity of lithium ion battery cell is 3.6V, if you want to reach high voltage in actual use , You need to connect multiple batteries in series to form an aspirational high-voltage platform. If you use the above characteristics to compare which is better between polymer batteries and lithium-ion batteries, then the conclusion is inevitable. However, the application of lithium-ion batteries in the market still accounts for the main position, which shows that lithium-ion batteries also have relative advantages, and we inherit the competition.
