What is the difference between mobile phone polymer lithium ion battery and lithium ion battery

What is the difference between a mobile phone polymer lithium-ion battery and a lithium-ion battery? 1. The fundamental difference is the raw material, which is the total source of the different performance of the two. Mobile phone polymer lithium ion battery refers to the use of polymer materials in at least one of the three major components of the positive electrode, negative electrode or electrolyte. Macromolecules mean large molecular weights, and the corresponding concept is small molecules. Macromolecules have high strength, high toughness and high elasticity. 2. Different shapes. Mobile phone polymer lithium-ion batteries can be thinner, arbitrarily shaped and arbitrarily shaped. The reason is that the electrolyte can be solid or colloidal rather than liquid. Lithium-ion batteries use electrolyte, which requires a solid The shell is used as a secondary package to contain the electrolyte. Therefore, this also makes lithium-ion batteries add a part of the weight. 3. In terms of safety, most of the current polymers are soft-pack batteries, which use aluminum-plastic film as the outer shell. When organic electrolytes are used inside, they will not explode even if the liquid is hot, because the aluminum-plastic film polymer battery uses solid or colloidal No leakage, but spontaneous rupture. But nothing is absolute. If the instantaneous current is large enough and a short circuit occurs, it is not impossible for the battery to spontaneously ignite or burst. The safety accidents of mobile phones and tablet computers are mostly caused by this situation. 4. Battery cell voltage Since the polymer lithium-ion battery of mobile phones uses polymer materials, it can be made into a multilayer combination in the battery to achieve high voltage, and the nominal capacity of the lithium-ion battery cell is 3.6V, if you want to use it in practice To achieve high voltage, multiple cells must be connected in series to form an ideal high-voltage working platform. 5. The solid electrolyte ion conductivity of conductive polymer batteries is low. At present, it is important to add some additives to make it a gel electrolyte to improve the conductivity. This is just a new addition of ionic conductivity, unlike the conductivity of lithium-ion batteries to maintain a stable value, and will not be affected by the quality of auxiliary materials. 6. The capacity of the polymer battery has not been effectively improved, and it has been reduced compared with the standard capacity lithium-ion battery. 7. Manufacturing process The thinner the polymer battery, the better the production, and the thicker the lithium-ion battery, the better the production, which makes the application of lithium-ion batteries more expandable. 8. Price This is a key factor that determines the market capacity of the two. At present, the price of polymer batteries on the market is generally higher than that of lithium-ion batteries, which affects the market capacity of the two. The ratio of the former to the latter is 1:9. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
