Abstract

A battery for powering a wearable device includes a first battery unit, a second battery unit interconnected with the first battery unit, and a connector electrically coupled between the first battery unit and the second battery unit. The connecting piece extends from the first battery unit to the second battery unit along the first direction. The length of the connecting piece along the first direction is greater than the distance between the first battery unit and the second battery unit. In some embodiments, the connector includes a fold structure configured to accommodate dimensional changes in the battery when the wearable device is bent.

Description

Technical field [0001] The present application relates to the field of energy storage devices in general, and particularly to a flexible lithium-ion battery. Background technique [0002] With the development of science and technology, a variety of electronic products have emerged, almost indispensable in everyday life. A lithium ion battery having a high energy density, long cycle life, renewable and environmentally friendly, etc., have been widely used in various electronic products. [0003] Wearable electronic device for battery requires a certain flexibility, so as to fit the shape of a wearable device and adapted to the shape and / or volume changes when the wearable device. Conventional batteries having a liquid electrolyte is not sufficiently flexible to meet the requirements of a wearable device. A battery having a gel or solid electrolyte by a low energy density and ion mobility difference in the pain. Therefore, desirable to have high flexibility while maintaining a hi...
