Description

technical field [0001] The invention relates to a self-chargeable battery, in particular to a battery with a built-in nano generator. Background technique [0002] With the rapid development of electronic technology, various electronic products such as sensors continue to appear, and even nano-sensing systems and application technologies have emerged. The market for rechargeable batteries that provide power for them is also expanding, such as lithium-ion, nickel-metal hydride batteries, etc. High-capacity, long-life green secondary batteries are highly regarded and have captured a large share of the small mobile market. However, in the field of application of micro-nano systems, especially for continuous detection systems of environmental systems or human body systems, such as temperature and pressure sensors in the surrounding environment, human pacemakers, pulse sensors and other medical micro-nano devices, the coexistence of medical micro-nano devices requires long-term p...
