　　The difference between liquid battery and polymer 18650 battery rechargeable

　　Nowadays, there are many types of lithium batteries used by people. Compared with the previous lead-acid batteries, various aspects such as working performance and safety factor have been greatly improved. However, in fact, there are many kinds of lithium batteries, such as liquid batteries and polymer batteries. Physical lithium batteries, although they are all lithium batteries, are actually very different.

　　liquid battery

　　First, the raw materials are different.

　　There are three main elements in the battery structure: positive stage, negative stage and electrolyte solution. At least one or more elements in lithium batteries are made of fiber materials. The polymer materials here refer to biological macromolecules. Objects generally have high compressive strength, good ductility, and good ductility.

　　However, judging from the currently produced polymer lithium-ion batteries, polymer raw materials are mainly used in the cathode or 18650 battery rechargeable electrolyte. The battery cathode material is an inorganic substance used in ordinary lithium batteries, or a conductive polymer. Materials, and battery cathode materials generally use lithium metal materials or lithium carbon solid layer materials.

　　18650 battery rechargeable electrolyte is made of solid or colloidal polymer electrolyte solution, which is similar to plastic film. It cannot transmit electronic devices, but it can carry out ion exchange (charged molecules or atomic groups), replacing the ions that penetrate into the 18650 battery rechargeable electrolyte. Traditional porous structure diaphragm. At the raw material level, the biggest difference from liquid lithium batteries is that its 18650 battery rechargeable electrolyte is made of liquid or colloidal solution 18650 battery rechargeable electrolyte.

　　Second, the styling design is different.

　　Because the electrolyte solutions of the two are different, there is a big difference in shaping. This is mainly because the electrolyte solutions of the two are different. The polymer lithium electrolyte solution is solid glue, which further improves the coordination ability of battery shaping design.

　　It can be thinned and deformed. In theory, it can be made thinner if the thickness is lower than that. It can also realize any area, any shape, better consider product needs, make batteries of any shape, and any volume, providing a flexible power supply solution for the development and design of solar lights, which can maximize its Product characteristics.

　　Lithium-ion batteries use lithium-ion battery electrolytes, which require a solid casing as secondary packaging to accommodate them. They are limited in size and shape, and will also increase the weight of the lithium-ion batteries.

　　Third, the safety performance is different.

　　In terms of safety, polymer lithium batteries also show great advantages, and most polymer lithium batteries use plastic soft packaging batteries, and the casing generally uses aluminum-plastic film. The results show that this type of junction material has excellent plastic deformation, flexibility and impact toughness, as well as excellent high barrier and heat sealing properties.

　　The internal electrolyte solution is a solid or colloidal solution, without unnecessary 18650 battery rechargeable electrolyte, so it is more stable and will not cause dangerous situations due to too few batteries, needle sticks, impacts or other damage, as well as excessive use. , Of course, things are not certain. If in an extremely harsh environment, if the current is too large for a moment, a short circuit failure is not impossible.

　　But in comparison, liquid batteries are safer. Liquid lithium batteries are prone to leakage, have a hard surface, poor heat dissipation capabilities, and are prone to explosion accidents.
