Which polymer lithium battery is better than lithium battery?

Lithium polymer batteries are safer than lithium batteries. Lithium polymer battery is an upgraded product of lithium battery. Relative to the current popular lithium battery, it has the advantages of large capacity, small size (thin), safety (no explosion) and so on. However, due to the time required for the replacement of the entire industry chain, its cost (cost) is currently relatively high, and it is only used in high-end digital products (ultra-thin notebook computers, etc.). It is foreseeable that in the next 5--10 years, lithium polymer batteries will surely replace existing lithium batteries! In fact, the penetration rate of lithium polymer batteries in Japan, South Korea and other countries where the electronic product industry is relatively developed has reached a certain level, but our country is still relatively backward in this regard, let us wait and see! In the near future, mobile phones using lithium polymer batteries will be cheaper, and I must replace this kind of safer mobile phone (battery)! Lithium polymer battery (Li-polymer, also known as polymer lithium battery): It has many distinct advantages, such as high energy density, smaller size, ultra-thin, lightweight, high safety and low cost. It is a new type battery. In terms of shape, lithium polymer batteries have the characteristics of ultra-thinness, and can be made into batteries of any shape and capacity according to the requirements of various products. The minimum thickness that this type of battery can reach can reach 0.5mm. Related to lithium batteries, the characteristics of lithium polymer batteries are as follows: 1. No battery leakage problem, the battery does not contain liquid electrolyte, and uses colloidal solids. 2. Can be made into a thin battery: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm. 3. The battery can be designed into various shapes. 4. The battery can be bent and deformed: the polymer battery can be bent up to about 90°. 5. It can be made into a single high voltage: a liquid electrolyte battery can only obtain high voltage by connecting several batteries in series, while a polymer battery can be made into a multi-layer combination within a single battery to achieve high voltage because there is no liquid. 6. The capacity will be twice as high as a lithium battery of the same size. Lithium-polymer batteries are theoretically better than lithium batteries, but they are not absolute. The batteries of the original factory are generally made of A products. The batteries are not defective in all aspects, and they are Japanese batteries produced in Japan. Both A and B products are generally The export products for their own use are generally CDE products. Their C products are equivalent to domestic A products and the sellers may send B products batteries. The domestic cost is low, but the quality is like the number of cycles and the craftsmanship is better. As far as the current situation is concerned, more and more mainstream manufacturers have begun to choose lithium polymer batteries, such as Apple, which are 100% polymer batteries. Regarding the difference between the seller and the original manufacturer, it is important It is because the batteries sent by sellers are mainly supplied by domestic contract manufacturers, and the source of goods is mainly secondary products and inferior waste products processed by mainstream lithium battery suppliers, so the prices are generally cheaper. This part of the battery may have some problems such as high self-discharge rate and small capacity, but generally it can be used according to the different electrolyte materials used in lithium batteries. Lithium batteries are divided into liquid lithium batteries (LiquifiedLithium-IonBattery, referred to as LIB) and polymerization Lithium battery (PolymerLithium-IonBattery, referred to as PLB) or plastic lithium battery (PlasticLithium-IonBatteries, referred to as PLB). The positive and negative materials used in polymer lithium batteries are the same as liquid lithium ions. The positive electrode materials are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. . The important difference between them lies in the difference in electrolytes. Liquid lithium batteries use liquid electrolytes, while polymer lithium batteries are replaced by solid polymer electrolytes. This polymer can be dry or colloidal, and most of them are currently used. Polymer gel electrolyte. Solid solid polymer electrolyte lithium battery electrolyte is a mixture of polymer and salt. This battery has high ionic conductivity at room temperature and can be used at room temperature. Gel-gel polymer electrolyte lithium batteries add plasticizers and other additives to the solid polymer electrolyte to improve ionic conductivity and allow the battery to be used at room temperature. Because polymer uses solid electrolyte instead of liquid electrolyte, compared with liquid lithium battery, polymer lithium battery has the advantages of thinner, arbitrary area, and arbitrary shape. Therefore, aluminum-plastic composite film can be used to make battery casings. It can improve the specific capacity of the entire battery; polymer lithium batteries can also use polymer as the cathode material, and its mass specific energy will be more than 20% higher than that of current liquid lithium batteries. Polymer lithium ion (PolymerLithium-IonBattery) batteries have the characteristics of miniaturization, thinning and light weight. Therefore, the market share of polymer batteries will gradually increase. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
