What are the advantages of polymer lithium battery compared with lithium battery? Polymer lithium battery is an upgraded product of lithium battery. Compared with the current popular lithium battery, it has the advantages of large capacity, small size and safety. It is foreseeable that in the next 5-10 years, polymer lithium batteries will replace existing lithium batteries! What are the advantages of polymer lithium batteries compared with lithium batteries? 1. There is no problem of battery leakage. The battery does not contain liquid electrolyte and uses colloidal solids. 2. Can be made into a thin battery: 3.6v400mah capacity, its thickness can be as thin as 0.5mm. The battery can be designed in a variety of shapes. Lithium polymer batteries are easier to make into thin and light batteries, and do not require a metal casing, so they are easier to customize. 4. Battery flexible deformation: the maximum flexible deformation of polymer batteries is about 900. 5. Can be made into a single high voltage: liquid electrolyte batteries can only be connected in series to obtain high voltage polymer batteries. 6. Since there is no liquid, multiple layers can be made in one particle to achieve high pressure. 1. Energy density: The higher the energy density, the greater the capacity per unit volume. By improving the material/thickness of anode and membrane, the energy density of lithium polymer can reach 600Wh/L+. 7. Safety: Under extreme conditions (such as overcharging/high temperature), the lithium battery will have a chemical reaction and a large amount of gas will appear. At this time, the liquid lithium battery will explode when the internal pressure is quite large because of the metal shell of the package. Due to the use of polymer lithium battery packaging aluminum film packaging (or plastic casing), as long as the internal pressure is slightly higher, it will expand or rupture, and will not explode. But it should be noted that both liquid lithium and polymer lithium can burn under extreme conditions. 8.Cost: Except that the material cost of polymer lithium battery is higher than that of liquid lithium battery, because a higher degree of polymer lithium battery can be customized, so in the process of design, manufacturing can incur more costs, such as various customized Tooling fixtures, test equipment, etc. The cost of polymer lithium batteries is higher than that of standard/regularly shaped liquid lithium batteries. The difference between polymer lithium battery and lithium battery Lithium polymer battery generally refers to lithium polymer battery. According to the different electrolyte materials used in lithium batteries, lithium batteries are divided into liquid lithium batteries and polymer lithium batteries or plastic lithium batteries. The concept of lithium battery is used very frequently. With a little attention, we will find that there are actually three differences with this concept: wide, narrow and narrow. Lithium batteries in a broad sense include lithium primary batteries and lithium batteries; because lithium batteries are more widely used than lithium primary batteries, lithium batteries usually refer to lithium batteries in a narrow sense; there are two types of lithium batteries: liquid polymer lithium batteries and lithium batteries, because The quality of lithium batteries is larger and more fluid. The narrow understanding of lithium batteries refers to liquid lithium batteries, polymer lithium batteries and lithium polymer batteries. People are used to polymer batteries. 1. The fundamental difference is that the raw material polymer battery refers to the use of at least one of the three components of polymer materials as positive, negative or electrolyte. The macromolecule refers to the mass of the macromolecule, and the corresponding concept is the small molecule. The macromolecule has high strength, high toughness and high elasticity. Currently, polymer battery materials are mainly used for positive electrodes and electrolytes. 2. Forming the difference. Lithium polymer batteries can be thin, flat and shapeless, because the electrolyte can be solid or gel instead of liquid, and lithium batteries use electrolytes, which requires a sturdy casing to carry out the two. Times package. Therefore, lithium batteries have added some weight. 3. Safety At present, most polymers are soft-pack batteries, and aluminum plastic film is used as the outer shell. When organic electrolyte is used inside, it will not explode even if the liquid is very hot, because the aluminum plastic film polymer battery does not use solid or colloidal state. Leakage is just a natural rupture. However, few are absolute. If the instantaneous current is large enough to cause a short circuit, it is not impossible for the battery to spontaneously ignite or burst. A security incident in Missouri.
