Why Lithium Polymer Battery So Popular

The lithium-ion battery electrolyte material different from the lithium-ion battery is divided into liquid lithium-ion battery (Liquified Lithium-Ion Battery, referred to as LIB) and lithium-ion polymer battery (Polymer Lithium-Ion Battery, referred to as the PLB) with lithium or plastic ion battery (Plastic Lithium ion batteries, referred to as the PLB). Anode and cathode materials used in lithium-ion polymer battery with liquid lithium-ion is the same, divided into cathode material of lithium cobalt oxide, lithium manganese oxide, LifePo4 ternary materials and materials, graphite is extremely negative, the battery works basically consistent. The main difference lies in the different electrolytes, liquid lithium-ion battery using a liquid electrolyte, lithium-ion polymer battery Zeyi solid polymer electrolyte to replace, such polymers can be "dry state", it can be "colloidal" currently most using a polymer gel electrolyte.


Solid: The solid polymer electrolyte lithium ion batteries and polymer electrolyte is a mixture of salts, such cells at high room temperature ionic conductivity, can be used at room temperature.

Gel: gel polymer electrolyte lithium ion batteries i.e., plasticizers and other additives added to the solid polymer electrolyte, thereby improving ionic conductivity, so that the battery can be used at room temperature.

Polymer: As the solid electrolyte instead of a liquid electrolyte, as compared with liquid lithium-ion batteries, polymer lithium ion battery having a thin shape, and of any area of any shape, etc., so you can use plastic composite film manufacturing batteries housing, which can improve the ratio of the entire battery capacity; polymer lithium-ion polymer battery can be also used as a cathode material, its quality will be improved by more than 20 percent more energy than the current liquid lithium-ion battery. Lithium-ion polymer (Polymer Lithium-Ion Battery) battery has a small, thin, lightweight characteristics. Thus, the polymer battery market share will gradually increase.

Polymer lithium ion battery has the following characteristics:
Shaping flexibility;
Higher quality than the energy (3 times the MH-Ni batteries);
The electrochemical stability window wide, up to 5V;
Perfect safety and reliability;
Longer cycle life, less capacity loss;
Volume utilization is high;
