Application:
Flexible Design:
Customizable Shape: They can be manufactured in various shapes and sizes to fit specific device requirements. For example, in wearable devices like smartwatches and fitness trackers, flat lithium polymer batteries can be designed to conform to the curved or slim form factors of these devices.
Thin Profile: They can be made extremely thin, with some capable of reaching thicknesses as low as 0.5mm. This is highly beneficial for applications where space is at a premium, such as in credit card-sized devices or ultra-thin laptops.
High Energy Density: They have a relatively high energy density, meaning they can store a large amount of energy in a small volume and lightweight package. This enables longer usage times for devices. For instance, in smartphones, flat lithium polymer batteries allow for all-day operation without the device being overly bulky or heavy.
Lightweight: Compared to some other battery types, flat lithium polymer batteries are lightweight, which is advantageous for portable applications. In drones, the use of lightweight flat lithium polymer batteries helps to reduce the overall weight of the drone, improving its flight performance and efficiency.
