High Capacity 3.7V Li Polymer Battery 606090 4000mAh for Rechargeable Devices
Product Description
Lithium polymer battery, often shorted as LiPo, LIP, Li-poly, lithium-poly among others, is a type of rechargeable lithium-ion battery that employs a polymer electrolyte instead of a liquid one, which made possible by the use of high conductivity semisolid (gel) polymers. Compares to other types of lithium battery, Li-polymer batteries has it's unique features that make them highly suitable for many applications such as laptop, camera, speaker ect. One of their most significant advantages is the form factor, it can be made into almost any shape you want, providing flexibility for device design. Also this battery is very lightweight, which make it suitable for the portable devices, particularly useful for consumer electronics like smartphones and laptops where space and design are key factors. In addition, they have a lower chance of suffering from electrolyte leakage compared to their lithium-ion counterparts, because they use a polymer electrolyte instead of a liquid one. The safety profile is further enhanced due to their robustness against overcharging. Last but not the least, they have a slow loss of charge when not in use, known as a low self-discharge rate, which makes them a convenient option for many electronic devices.
