First of all, many terms are used for this type of battery. If you look at the industry literature, you will see other terms for the product, such as prismatic or cylindrical cell.
In basic technology, there are differences between the technologies in terms of these power supplies. Often polymers are the type of electrolyte used in these units.
Today's lithium polymer batteries uses a gel that allows high conductivity. In addition, most of these devices have the microporous separator required for this unit. Unlike other batteries, the difference lies in the use of the separator and the electrolyte.
This cell filling and discharging speed is the same as other popular types. Therefore, it is possible to use a normal charging system for general items such as a power bank.
It is possible to use a USB resource, but the hardware takes control of the process. The same scheme can usually be used. When it comes to lithium polymer cells and batteries, manufacturers follow a different manufacturing process. Common primary lithium-ion units use cylindrical or box cells called prismatic cells.
Lithium polymer cells also use a foil pouch format. And it's like chewing gum. Hence, it can be made thinner than usual. This is very attractive to most manufacturers, especially if they are looking for thinner devices like cell phones and laptops.
Today's lithium polymer batteries have a film-like body and high-quality laminate plates. Therefore this unit is much lighter. Unlike the other alternatives, they are up to 20% lighter.
