1. Different principles

Lithium battery can be roughly divided into two categories: lithium metal battery and lithium-ion battery. Lithium metal batteries are usually non rechargeable and contain metallic lithium. Lithium ion batteries do not contain metallic lithium and can be charged.

Lithium polymer battery refers to all solid state or gel is too electrolyte for lithium ion batteries, generally use aluminum plastic composite membrane as packaging material.

2. Different raw materials

In addition to the inorganic compound of lithium battery, the conductive polymer can also be used as the anode material of polymer battery. The electrolyte of polymer battery includes polymer electrolyte (solid or colloidal) and organic electrolyte.

3. Shape difference

Polymer battery can be thin, area and shape, because its electrolyte can be colloidal rather than liquid.

The lithium battery uses electrolyte, which needs a solid shell as the secondary packaging to contain the electrolyte. As a result, it also adds some weight to the lithium battery.

4. Conductivity

The conductivity of lithium battery keeps a stable value, which is not affected by the quality of auxiliary materials.

The solid electrolyte of polymer battery is low in ionic conductivity. At present, some additives are added to make it a gel electrolyte to improve conductivity.

5. Manufacturing process

The thinner the polymer battery, the better the production, the thicker the lithium battery, the better the production, which makes the application of lithium battery pack can expand more fields.

In general, to compare the differences between lithium polymer battery and lithium battery, the only thing is the relationship between concept and generic concept. Lithium polymer battery is included in lithium battery.
