Lithium polymer batteries use the same technology employed by lithium-ion battery liquids. Also, the cathode, as well as the anode, are of the same design. The only difference is that these devices make use of aluminum-plastic films or gel electrolytes. 

This means that these power packs are smaller and lighter, but they also provide a greater energy density.

1. High Energy Density

In comparison to nickel-cadmium or nickel-hydride lithium polymer batteries weighs 50% less. However, they possess the same energy density, making them the perfect option.

2. Thin Design

Liquid lithium-ion batteries come with an individual shell, as well as positive and negative electrodes. Then there's a limitation in technology that doesn't permit the batteries to be less than 3.6mm. However, the polymer cells don't have any limitations like this. So the size of these cells can be under 1 mm.

3. Low Internal Resistance

As opposed to liquid batteries, the polymer version has lower internal resistance. This means that these batteries will assist in prolonging the period that your applications are in standby mode. This is an important benefit of these batteries.

4. Customizable Shape

Based on the demand In response to demand, polymer batteries may be made stronger or less. For instance, in the case of special smartphones, manufacturers might require thinner batteries. This helps make the most of the space available and also get a long-lasting backup.
