At present, the energy storage devices that can provide electric energy for electronic products on the market mainly include batteries and capacitors.
Supercapacitors and batteries can store a large amount of electric energy and can be used as power supply sources. Batteries are very common in life, whether it is computers, remote controls, or toys, most of them use batteries to provide energy to run, and the commonly used batteries are lithium batteries. Compared with other capacitors, supercapacitors have a large electrostatic capacitance, but there is still a gap compared with lithium batteries.
Although supercapacitors are not as good as lithium batteries in terms of power, the charging speed of supercapacitors is faster than that of lithium batteries. Supercapacitors have no chemical reaction during energy conversion and they charge and discharge quickly, but their energy density is much lower than that of lithium batteries. Lithium batteries store energy in a chemical form, and there is a chemical reaction during energy conversion. Its energy density is high, but the charging speed of lithium batteries is quite slow.
Lithium batteries can only maintain a good working condition within a limited number of charge and discharge times. Once the number of charge and discharge times is exceeded, the performance of lithium batteries will be greatly reduced, while supercapacitors can be repeatedly charged and discharged tens of thousands of times to hundreds of thousands of times. This is also the advantage of supercapacitors.
They can be combined to use their strengths to complement each other’s weaknesses. One electronic component that offers the best of both worlds is the hybrid supercapacitor. Hybrid supercapacitors offer the best of both worlds, storing more energy than conventional supercapacitors while maintaining charging speed. Although hybrid supercapacitors are not popular yet, it is believed that with the development of technology, hybrid supercapacitors will become commonly used electronic components in the near future.
