The invention discloses an all-weather uninterrupted self-powered energy system and an application thereof. The all-weather uninterrupted self-powered energy system comprises a flexible thin film solar cell and a flexible solid state ion cell, wherein the flexible thin film solar cell is used for generating power by absorbing solar energy and by means of rubbing mechanical energy; and the flexiblethin film solar cell is electrically connected with the flexible solid state ion cell, and is used for charging the flexible solid state ion cell in order to provide power for electric devices through the flexible solid state ion cell. The all-weather uninterrupted self-powered energy system obtained in the above manner has strong applicability, is not limited to the influence of a complicated external weather environment, and can fully convert and utilize natural energy to realize all-weather uninterrupted self-powered energy. In addition, the system can be applied to various electrical devices, can integrally reduce the weights of the product devices, and can be folded to achieve convenient carrying and storage.
