Advantages of Supercapacitors over Lithium Batteries

Jul. 04, 2022

Supercapacitor, also known as gold capacitor, farad capacitor, is a new type of electrochemical capacitor. Its special feature is that no chemical reaction occurs in the process of storing electrical energy. Due to the working principle, supercapacitors can be charged and discharged hundreds of thousands of times, so the working time is long.


In recent years, super capacitors have gradually replaced ordinary capacitors due to their large storage capacity. The capacitance of supercapacitors of the same volume is much larger than that of ordinary capacitors. The capacitance of supercapacitors has reached the Farad level, while the capacitance of ordinary capacitors is very small, usually at the microfarad level.


Supercapacitors can not only replace ordinary capacitors, but may replace lithium batteries in future development.


So what are the differences between supercapacitors and lithium batteries? Compared with lithium batteries, what are the advantages of supercapacitors? Read this article to see.


Advantages of Supercapacitors over Lithium Batteries


1. Working principle:


The energy storage mechanism of supercapacitors and lithium batteries is different. Supercapacitors store energy through the electric double layer energy storage mechanism, and lithium batteries store energy through chemical energy storage mechanisms.


2. Energy conversion:


There is no chemical reaction when supercapacitors convert energy, while lithium batteries perform energy conversion between electrical energy and chemical energy.


3. Charging speed:


The charging speed of supercapacitors is faster than that of lithium batteries. It can reach 90% of the rated capacitance after charging for 10 seconds to 10 minutes, while lithium batteries only charge 75% in half an hour.


4. Duration of use:


Supercapacitors can be charged and discharged hundreds of thousands of times, and the use time is long. It is very troublesome to replace the battery once the lithium battery is charged and discharged 800 to 1000 times, and the use time is also short.


5. Environmental protection:


Supercapacitors do not pollute the environment from production to use to disassembly, and are ideal environmentally friendly energy sources, while lithium batteries cannot be decomposed, causing serious pollution to the environment.


From the differences between supercapacitors and lithium batteries, we can see that the advantages of supercapacitors are much better than those of lithium batteries. With the above advantages, supercapacitors have broad prospects in new energy vehicles, Internet of Things and other industries.


Select a reliable manufacturer when purchasing supercapacitors can avoid a lot of unnecessary trouble. JYH HSU (or Dongguan Zhixu Electronics) not only has full models of ceramic capacitors with guaranteed quality, but also offers worry-free after-sales. JEC factories has passed ISO9001:2015 quality management system certification; JEC safety capacitors (X capacitors and Y capacitors) and varistors have passed the certification of various countries; JEC ceramic capacitors, film capacitors and super capacitors are in line with low carbon indicators.
