1. Which is better, lithium polymer battery or lithium battery, of course, polymer battery is better, it is also a kind of lithium ion battery, but compared with liquid lithium battery (Li-ion), it has high energy density and high safety. To be precise, it should be said: lithium polymer battery; according to the different electrolyte materials used in lithium ion batteries, lithium ion batteries can be divided into two categories: liquid lithium ion batteries and polymer lithium ion batteries. So the "lithium ion battery" written in the manual is also correct.

    2. When analyzing the life of polymer batteries and lithium batteries, according to the different electrolyte materials used in lithium ion batteries, lithium ion batteries can be divided into liquid lithium ion batteries and polymer lithium ion batteries) or plastic lithium ion batteries. The positive and negative materials used in polymer lithium-ion 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 also basic. Unanimous.

    3. Polymer batteries and lithium batteries have a relatively long service life. However, the basic welding method of this polymer battery also depends on what product the battery is used for. Generally speaking, the polymer battery is used to a certain extent. Will bulge, and cylindrical lithium batteries will not appear this phenomenon.

    4. Polymer batteries and lithium batteries are actually one of the lithium ion batteries. Nowadays, polymer batteries are generally made of lithium nickel cobalt manganese ternary materials. You may want to combine polymer batteries with 18650 Compare the series of cylindrical lithium-ion batteries. Their materials, voltages, discharge platforms, etc. are similar. There are lithium cobalt oxide and ternary series, but one adopts the aluminum composite film soft package process, and the other is Steel shell encapsulated, polymer ones are usually used alone, such as mobile phone batteries, digital camera batteries, etc., while 18650 batteries are mostly used for series and parallel battery packs.

    Lithium-ion batteries and lithium-polymer batteries have their own advantages and disadvantages; polymer lithium batteries and lithium-ion batteries have different advantages and disadvantages. The application mainly depends on the overall performance requirements of the product. You cannot say which one is better.
