The advantages and disadvantages of lithium ion battery and lithium polymer battery

Source: 2020 - 04 - 15 18:58 hits: the advantages and disadvantages of lithium ion battery and lithium polymer batteries have seen iphone blasts of news, is lithium battery explosion in the mobile phone, and there are many kinds of lithium battery. For example: the lithium ion battery and lithium polymer battery, but all have their own advantages and disadvantages, for ordinary users, probably know very little. Some people say that the lithium polymer battery is better than lithium ion batteries? So this is not true, the author will introduce the two batteries on the price, performance and security what are the advantages and disadvantages. First of all, from the principle of battery, lithium polymer battery and lithium ion battery. The fundamental difference of the two batteries is that they use within different electrolytes. We all know that lithium ion battery using liquid electrolyte, polymer lithium ion battery using solid polymer electrolyte, it can be solid or semisolid. 18650 battery, however, the appearance of the two kinds of battery, is now the most common cylindrical lithium-ion batteries, there is a piece of lithium polymer. Lithium ion batteries due to contain active metal, easy to burn even explode. In the lithium ion battery cathode material adding cobalt, manganese and other metal materials, greatly improving the safety coefficient of early lithium ion batteries. Lithium battery is safer now, you don't have to worry too much about this problem. Finally, due to its high energy density, excellent safety performance and constantly changing shape, soft polymer coating has become the mainstream electronic and digital products of choice. But the 18650 steel battery shell still has certain advantages on price. Polymer battery let's take a look at how the lithium ion battery discharge. When discharge lithium ion, lithium ion into the electrolyte from the anode material, and then into the anode materials. This process is called disassembly. Actually steel shell lithium-ion batteries, lithium-ion batteries or soft package, now the factory's technology has been very mature, brand battery safety performance is very good, if used properly, there will be no so-called explosion, fire and other accidents, such as to avoid the high temperature environment used batteries, battery short circuit and overload, piercing, etc. Therefore, these two types has its own advantages and disadvantages. According to your need to choose is wise. If you prefer to choose cost-effective for 18650 battery pack, if you prefer the appearance of the equipment and volume, the polymer is undoubtedly the best choice.
