What is the difference between a lithium-ion battery pack and a polymer lithium-ion battery

What is the difference between a lithium-ion battery pack and a polymer lithium-ion battery


Lithium polymer battery has many obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, high safety and low cost, and is a new type of battery. In terms of shape, lithium polymer batteries have the characteristics of ultra-thin, and can be made into batteries of any shape and capacity according to the needs of various products. The minimum thickness that this type of battery can achieve is up to 0.5mm.


 


In the polymer lithium-ion battery, the electrolyte plays the dual function of the separator and the electrolyte: on the one hand, it separates the positive and negative materials like the separator, so that no self-discharge and short-circuit occur inside the battery, on the other hand, it acts like the electrolyte. Lithium ions are conducted between the positive and negative electrodes. Polymer electrolytes not only have good electrical conductivity, but also have the characteristics of light weight, good elasticity, and easy film formation that are unique to polymer materials.


 


The lithium iron phosphate battery pack material does not contain any heavy metals and rare metals, non-toxic, no pollution in production and use, in line with European RoHS regulations, and is a green battery. However, there is a large amount of lead in lead-acid batteries. If they are disposed of improperly, they will still cause secondary pollution to the environment.


 


Compared with lithium-ion battery packs, polymer lithium-ion batteries have many advantages, such as: the shape can be made thinner, the capacity is about 15% higher than that of lithium-ion batteries, and the weight is light. It is often used in portable devices such as mobile phones and mp3. .
