Self-made energy storage power supply

Could a flexible self-charging system be a solution for energy storage?

Considering these factors, a flexible self-charging system that can harvest energy from the ambient environment and simultaneously charge energy-storage devices without needing an external electrical power source would be a promising solution.

Why do we need a new energy supply system?

The intermittent environmental energy may cause the interruption of the power supply to the device. New types of energy conversion, storage, and supply systems with improved efficiency and reliability are therefore highly desirable.

What are flexible self-charging power sources?

Flexible self-charging power sources integrate energy harvesters, power management electronics and energy-storage units on the same platform; they harvest energy from the ambient environment and simultaneously store the generated electricity for consumption. Thus, they enable self-powered, sustainable and maintenance-free soft electronics.

Why do we need energy storage units?

To utilize such abundant, intermittent and randomly distributed energy sources, compatible energy-storage units that convert the harvested electricity into electrochemical energy and output electricity for consumption are indispensable for power stability and sustainability.

How long does a continuous self-power supply last?

It means that in practical application scenarios, CECIS can achieve a 24-h continuous self-power supply as long as the actual working time exceeds one-tenth of a day. In summary, CECIS has been designed and assembled by C-TENG and CSSC to achieve the collection, conversion, and storage of high-entropy energy for a continuous self-power system.

Is solar energy a good option for a self-sufficient system?

While solar power is effective, having diversifying energy sources enhances the reliability of a self-sufficient system. Wind turbines, especially smaller residential models, offer an excellent complement to solar energy.
