The development of a flexible lithium-ion battery in Japan is expected to be used for wearable terminals

Japan's Semiconductor Energy Research Institute, which is engaged in new technology research and development in semiconductors, has developed a flexible lithium battery, the Japanese economic News reported 2nd. The thickness is 2 mm, and the positive and negative electrode materials are of high flexibility. The developed battery can be freely bent by a near-plane state. Aluminum on the outside of the micro-convex, flexible. Strive to be used in the future to be popular wearable terminals. It is alleged that the battery overlaps the cathode material coated with lithium cobalt oxide on aluminum foil with the cathode material coated with carbon on the copper foil. When the battery is bent, tension is exerted upward and pressure downward. Through the use of concave-convex design, external installation can be telescopic, thereby relieving pressure, will not produce cracks. After 10,000 bending tests on the battery, the Semiconductor Energy Research Institute found no change in charge and discharge performance and external loading. It is expected to be equipped with the inside of the hand ring terminal and the ear of the glasses leg. In this, the terminal manufacturer's product design flexibility will be improved. The Semiconductor Energy Research Institute says it has started business negotiations on its applications.
