How to distinguish between polymer batteries and lithium ion batteries?

How to distinguish between polymer batteries and lithium-ion batteries? Today, a friend asked a lithium-ion battery manufacturer a question: because he just bought a mobile phone, the battery says polymer battery, but the manual says lithium ion battery. My friend was stunned and wanted to know if the two batteries are the same. So today the manufacturers of lithium-ion batteries tell you what is a polymer battery; what is a lithium-ion battery. Which of the two batteries is better? First, let's take a look at the polymer battery: polymer lithium ion battery, also known as lithium polymer battery, is a kind of lithium ion battery, a new type of battery, compared with liquid lithium ion battery, It has the advantages of high energy density, small size, ultra-thin, light weight, high safety, and low cost. In terms of shape, lithium polymer batteries have the characteristics of ultra-thin, which can meet the requirements of various products and be produced into batteries of any shape and capacity. The minimum thickness of the battery can reach 0.5mm. Its nominal voltage is the same as that of lithium ion, 3.6 or 3.7V, and there is no memory effect. What is a lithium ion battery? A lithium ion battery is a rechargeable battery whose working principle is that lithium ions move between the positive and negative electrodes. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes. In rechargeable batteries, lithium ions are extracted from the positive electrode and inserted into the negative electrode through the electrolyte. The negative electrode is in a state rich in lithium. When unloading, the situation is just the opposite. Batteries generally use materials containing lithium as electrodes. It is a representative of modern high-performance batteries. Comparison of polymer batteries and lithium ion batteries: to be precise: lithium polymer batteries; lithium ion batteries can be divided into liquid lithium ion batteries and polymer lithium ion batteries according to the different electrolyte materials used in lithium ion batteries. So: polymer battery is better! It is also a kind of lithium ion battery, but it has higher energy density and safety than lithium ion.
