Description of the Invention: [Technical Field] The present invention relates to a package structure, and more particularly to a package structure for a high performance energy storage element. [Prior Art] The storage component of electric energy accounts for an important part of our life, such as the capacitance of the circuit towel and the battery of the portable device, and the electrical energy storage component affects the execution of the electronic device. Performance and job time' while performance and availability are required for each design. In the past, the backup power solution was a battery, mainly lead-acid batteries, and now there are more options to meet the needs of backup power, including advanced battery technology such as clock ions, nickel-metal hydride batteries, (four) batteries, solar cells and double Layer capacitance, etc. Lithium-ion, nickel-hydrogen batteries and other battery technologies have made great strides in providing reliable energy storage solutions. They have been used in many designs and have solved many of the cost problems of the past but still face the same problems as when using alumina batteries, ie all of these technologies are based on chemical reactions, their service life is limited and subject to temperature The limits, and the need for high currents, also directly affect their useful life. As a result, these battery technologies face some challenges in terms of durability and reliability. Supercapacitors, or electrochemical double layer capacitors (EDLC), have very high power densities and substantial energy densities compared to electrolytic capacitors. In the past few years, these components have been used in many fields, such as consumer electronics, industrial and automotive. Today, supercapacitors are ultra-high power components with power densities up to 2〇kw/kg. Supercapacitors are very compact (small supercapacitors are usually only stamp size or smaller), but they can store more energy than conventional capacitors. Too much higher, the capacity of most supercapacitors is calibrated (F), usually between 1F and 5,000F, and the discharge rate can be very fast or slow. They have a very long service life and can be designed for the entire life cycle of an end product. In the future, high-performance energy storage components such as supercapacitors and magnetic capacitors will be widely used in many fields. Therefore, there is a practical need for a package structure of energy storage components. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a package structure for a high efficiency energy storage component.
