What is the difference between polymer batteries and lithium batteries.solar generator for house

　　1. The fundamental difference is the raw materials

　　It is the overall fundamental reason for the various differences between the two. Polymer batteries refer to the application of fiber materials in at least one of the three major components: positive, negative, or electrolyte. The meaning of polymer materials is relatively high molecular weight, and the definition of relativity is small molecular water. Polymer materials have high toughness, high wear resistance, and high elasticity. At present, the polymer battery fiber material developed for the product is mainly used for positive electrode and electrolyte.

　　① In addition to using inorganic materials from lithium batteries, polymer battery positive electrode materials can also use conductive polymer materials such as polymers;

　　② The electrolytes of polymer batteries include polymer material electrolytes (solid or colloidal) and organic chemical lithium battery electrolytes. Lithium batteries use lithium battery electrolytes (liquid or colloidal solutions)

　　2. Differences in shaping

　　Polymer batteries can ensure thinness, arbitrary total area, and arbitrary appearance, depending on whether their electrolyte can be solid or colloidal rather than liquid. For lithium batteries, lithium battery electrolyte is chosen, and a solid casing must be used as a secondary packaging to hold the lithium battery electrolyte. Therefore, this has also led to a partial increase in the net weight of lithium batteries.

　　3. Safety factor level

　　Today's high polymer batteries are mostly soft pack batteries, using aluminum plastic film as the casing. When organic chemical electrolytes are used internally, even if the liquid is very hot, there will be no explosion. Due to the use of solid or colloidal aluminum plastic film polymer batteries, there is no liquid leakage and only natural cracking. But everything is not certain. If the current is sufficient in an instant and a short circuit fault occurs, it is not impossible for the charging battery to catch fire or crack. The occurrence of safety production accidents on mobile phones and tablets is often caused by such conditions.

　　4. Operating voltage of lithium battery cells

　　Because polymer batteries use fiber materials and can be made into a double-layer composition in lithium cells to achieve high voltage, while the allowable volume of lithium cells in lithium batteries is 3.6V. To achieve high voltage in specific applications, several lithium cells must be connected in series to create an ideal high voltage operating platform. If many of the above characteristics are compared to which is better, polymer batteries or lithium batteries, then the result is certain. Little does it know that in the sales market or the use of lithium batteries accounts for the main influence of behavior, which indicates that lithium batteries also have relative advantages. Let's compare again.
