The principle is different. Let's start with lithium-ion batteries and lithium-ion batteries (the polymer is also lithium-ion batteries).
Lithium battery is a kind of lithium metal or lithium alloy as the anode material, because the chemical characteristics of lithium metal is very active, so that the processing, storage, use of lithium metal, environmental requirements are very high. The anode of lithium-ion batteries is intercalated material such as graphite. In the battery, lithium-ion moves in the anode and cathode, so it is much safer than a lithium battery. Then there are lithium-ion and lithium-polymer batteries.
Lithium-ion batteries have a liquid electrolyte, while polymer batteries have gel or solid electrolyte, which is safer.
First of all, we now lithium battery, according to the scientific name, should be called lithium secondary battery, have the corresponding anode material, and lithium battery is different, a battery is mainly lithium as another pole, this kind of battery generally use liquid electrolyte, now is mainly based on LiPF6, LiClO4 dissolved in DMC: EC(V: V =1:1) electrolyte, Some have been modified, but they are still liquid batteries.
Polymer lithium battery, from the point of view of the material inside the battery, the main internal electrolyte is the polymer electrolyte, here is usually a gel electrolyte and solid electrolyte, if I remember correctly, the Koreans have published a gel battery with PEO- ionic liquid as the electrolyte. I don't know if there are any such batteries in the GalaxyRound or the LGGFlex.
Secondly, lithium polymer battery box lithium battery in the packaging is slightly different, lithium battery is generally steel shell (18650 or button type 2320), and lithium polymer battery to aluminum-plastic packaging film as the packaging, that is, soft pack battery.
Of course, there are lithium batteries with all solid electrolytes such as Ligon, Nasicon, perovskite, Lisicon, ceramic electrolytes with high conductivity or glass electrolytes made of amorphous materials. If you want to classify them, they should probably be classified as lithium secondary batteries, but this is an extension of the concept
Finally, lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-metal batteries are usually non-rechargeable and contain metallic lithium. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium-ion batteries and lithium-polymer batteries are different in principle.
