What is the difference between polymer batteries and general lithium batteries

There are two types of lithium batteries: polymer lithium batteries and liquid lithium batteries. Because they are used more and more widely in liquid lithium batteries, lithium batteries in a narrow sense refer to liquid lithium batteries. Polymer lithium batteries, also known as lithium polymer batteries, are often referred to as polymer batteries. If you compare the difference between lithium polymer batteries and lithium batteries in a broad and narrow sense, the only problem is the relationship between concepts and concepts. Lithium polymer batteries are included in lithium batteries. Therefore, the comparison in the narrow sense is of comparative significance, that is, the comparison between polymer batteries and liquid lithium batteries. On this basis, lithium batteries are used to replace liquid lithium batteries. 1. The fundamental difference is the raw material. This is the overall source of these two different manifestations. Polymer battery refers to the use of polymer materials in at least one positive-negative or electrolyte module. Macromolecules refer to large molecular weights and correspond to the concept of small molecules. Polymers have high strength, high toughness and high elasticity. Polymer materials for polymer batteries are critically used for cathodes and electrolytes. 1. Polymer battery materials can use conductive polymers and inorganic compounds of lithium batteries; polymer batteries have polymer (solid or organic) and organic, lithium battery uses (liquid or other). 2. In terms of shaping and safety, the polymer battery can be thinner, in any shape and any shape, because the electrolyte can be a solid colloid instead of a liquid, and the lithium battery uses an electrolyte, and a strong case is required as a secondary packaging to contain the electrolyte. . Therefore, this also adds to the weight of lithium batteries. Most of the current polymer batteries are soft-packaged batteries. The shell is made of aluminum plastic film. When using organic electrolytes, even if the liquid is very hot, the liquid will not explode. The aluminum plastic film polymer battery adopts solid or colloidal state, no leakage, but it can only be broken naturally. But nothing is absolute. If the instantaneous current is large enough and a short circuit occurs, the battery is unlikely to ignite or explode. The security accidents of mobile phones and tablet computers are mainly caused by this situation. 3. The solid electrolyte of the conductive polymer battery has low ion conductivity. At present, some additives have been added to make it a gel electrolyte to improve conductivity. This will only increase the ionic conductivity, unlike the conductivity of lithium batteries to maintain a stable value without being affected by the quality of the auxiliary materials. 4. Battery cell voltage Since polymer batteries use polymer materials, they can be made into a multilayer combination in the battery to obtain high voltage. The rated capacity of lithium battery cells is 3.6V. In actual use, in order to obtain high voltage , It is necessary to connect multiple cores in series to form an ideal high-voltage working platform. If the polymer battery and lithium battery are compared with the above characteristics, the conclusion drawn is affirmative. However, the use of lithium batteries dominates the market, which states that lithium batteries also have comparative advantages, and we will continue to compare them. 5. Manufacturing process and price The thinner the polymer battery, the better the processing. The thicker the lithium battery, the better the processing, which makes the lithium battery more expandable in the scope of use. At present, the price of polymer batteries is generally higher than that of lithium batteries, which affects its market capacity. The ratio of the former to the latter is 1:9.
