Lithium Polymer Battery LP105085 3.7V 5000mAh

Lithium polymer batteries are originally saying the lithium battery with gelled electrolyte, but it is commonly referred to as the soft bag battery or pouch cell battery today. From the name of “soft bag” and “pouch”, we can see it doesn’t have a hard battery shell such as the cylindrical cell or the prismatic cell.  The cylindrical and the prismatic battery cells have rigid cases, and the polymer battery has a soft film type enclosure. Besides this, it’s almost the same technology as other types of lithium-ion batteries.

Thanks to the flexible foil-type case, polymer batteries can be built into very thin and flexible shapes

It’s smaller and lighter, the weight is averagely 20% less than the same capacity cylindrical and prismatic battery cells.

It’s could be extremely thin, so it can fit inside the electronics perfectly.

It doesn’t have a hard shell, it’s much safer when there are pressures inside the cell compared to the rigid case battery。

It’s born for handheld equipment and electronics products. Most importantly, polymer batteries changed the product design concept, it goes to fit the product design, while the product has to go fit the 18650 or other types of batteries.
