The principle is different, first say lithium battery and lithium ion battery (polymer is also lithium ion battery).
Lithium battery is a kind of lithium metal or lithium alloy as the anode material, because of the chemical characteristics of lithium metal is very active, so that the processing, preservation, use of lithium metal, the environmental requirements are very high. Lithium-ion batteries are much safer than lithium-ion batteries because the cathode of lithium-ion batteries is made of graphite and other intercalated materials. Then there are lithium ion batteries and lithium polymer batteries.
Lithium-ion batteries have a liquid electrolyte, while polymer batteries have a 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, there are corresponding anode materials, and lithium primary battery is different, a battery is mainly lithium as the other pole, this kind of battery generally use liquid electrolyte, now mainly based on LiPF6, LiClO4 dissolved in DMC:EC(V: V =1:1) electrolyte, Some are modified, but still liquid.
From the point of view of the internal material of the battery, polymer is mainly used for the internal electrolyte, which is generally gel electrolyte and solid electrolyte. If I remember correctly, Koreans once published a gel battery with PEO-ionic liquid as electrolyte. I don't know if this battery is used in the GalaxyRound or lg flex.
Secondly, lithium polymer battery box Lithium battery in the packaging is slightly different, lithium battery is generally steel case (18650 or buckle 2320), and lithium polymer battery to aluminum plastic packaging film as a package, that is, soft pack battery.
Of course, lithium batteries are made of all-solid electrolytes LiPON, NASICON, perovskite, LiSICON and other ceramic electrolytes with high conductivity or glass electrolytes composed of amorphous materials. If it is necessary to classify, it may be classified in 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 can be recharged. Lithium batteries, lithium ion batteries and lithium polymer batteries are different in principle.
