Polymer batteries and lithium batteries are better than polymer batteries. The fundamental difference between the two lies in the different raw materials.
Polymer battery refers to the use of polymer materials in at least one of the three main components of the positive electrode, negative electrode or electrolyte. Polymer means large molecular weight and its corresponding concept is small molecules. Polymers have high strength, high toughness and high elasticity. Polymer materials currently developed for polymer batteries are mainly used for cathodes and electrolytes.
Lithium batteries use electrolyte (liquid or colloid). Electrolyte is the medium used by chemical batteries, electrolytic capacitors, etc. (it is corrosive to some extent) to provide ions for their functionnormal operation. And make sure the chemical reactions that occur during work are reversible.
Polymer batteries can be thin, in any area and in any shape, because the electrolyte can be solid or colloidal rather than liquid. Most current polymer batteries are soft batteries, which use aluminum-plastic film as the outer casing. When organic electrolytes are used inside, the liquid does not explode even if it is very hot, because the aluminum-plastic film polymer battery. is in a solid or colloidal state without natural leakage.
Since polymer batteries use polymer materials, they can be made into multi-layer combinations in the battery core to achieve high voltages. The rated capacity of lithium battery cells is 3.6V. practical applications, voltage, multiple cells shouldt be connected in series to form an ideal high voltage working platform.
Comparing the above characteristics between polymer batteries and lithium batteries, which one is better, then polymer batteries must be better.
