How is the capacity of flat lithium polymer batteries compared to other types?
Compared with cylindrical lithium polymer batteries:
Generally lower capacity: Cylindrical lithium polymer batteries usually have a higher capacity. For example, cylindrical batteries can often reach a capacity of up to 3,500 mAh, while flat lithium polymer batteries typically have a capacity of up to 2,000 mAh. This is because cylindrical batteries are often manufactured using a winding process, which allows for more electrode material to be packed in, resulting in a higher capacity.
Different application scenarios due to capacity differences: Cylindrical batteries, with their higher capacity, are commonly used in applications that require high power output and long 续航,such as power tools, electric vehicles, and drones. Flat lithium polymer batteries, despite having a lower capacity, are preferred in applications where space is limited and a low profile is required, like smartphones, tablets, laptops, and wearable devices.
