How to distinguish polymer batteries?

1. Replace the original liquid electrolyte with a solid electrolyte, 2. Replace the carbon anode material with a lithium ion anode material 3. Lightweight 4. Ultra-thinness 5. Flexible shape: It can be made into different shapes according to different needs 6 , Safety improvement: Even if it is overcharged, it is very stable. Because the electrolyte is solid, the probability of leakage becomes very low. FPV UAV battery picture 2. From the exterior packaging and the internal composition 1. Sheet shape: If the outside is wrapped with a sticker, first use two hands to repeatedly break it back and forth. If there is a plastic frame on the side, then it is very likely It is a general lithium ion, not a polymer. Peel off the sticker to expose the battery core. If the edge is a rectangular parallelepiped, it may be ordinary lithium ion. If the edge is an arc-shaped battery, and there are gaps in the packaging metal sheet, it may be a polymer. The polymer battery can continue to be disassembled, showing a similar vacuum-encapsulated aluminum foil. Generally, lithium ion only shows the metal shell square cell, if you rely on your hands, you can't continue to disassemble it. 2. Barrel shape, usually contains more lithium ion and less polymer. Most polymers are much flatter. 3. Product attributes Li-polymer battery (Li-polymer, also known as polymer lithium battery): It is also a kind of lithium battery, but compared with liquid lithium battery (Li-ion), it has higher energy density and smaller size , Ultra-thin, lightweight, and high safety and other advantages, is a new type of battery. In terms of shape, lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of any shape and capacity according to the needs of various products. The minimum thickness that this type of battery can reach can reach 0.5mm. Its nominal voltage is the same as that of Li-ion and it is also a nominal voltage of 3.7 volts, with no memory effect. And the polymer battery is mixed with the positive electrode active material and the negative electrode active material respectively by the solvent and the binder. After being evenly stirred at high speed, a slurry-like positive and negative material is made. Solid electrolyte.
