FLEXIBLE BATTERY, SUPPLEMENTARY BATTERY AND WATCH STRAP COMPRISING THE FLEXIBLE BATTERY

摘要

A flexible battery is provided. According to an example embodiment of the present invention, a flexible battery includes: an exterior material sealing an electrode assembly and an electrolyte; an electrode terminal electrically connected to the electrode assembly, and disposed on a side of the exterior material to protrude therefrom; and an electrode terminal insulating cover disposed to surround the electrode terminal to prevent heat from being transmitted to the inside or outside of the flexible battery through the electrode terminal. The assembly assembly and the exterior material are formed so that a pattern for contraction and relaxation in a length direction thereof has the same directivity when bent. Accordingly, the flexible battery may have excellent barrier properties for heat transfer between the inside and outside thereof through the electrode terminal of the flexible battery, and may have excellent durability while having highly outstanding flexibility, thus being applied to various types of electronics which requires the flexibility such as a rollable display as well as a wearable device including a smart watch and a watch strap.
