Product Introduction:

         Graphene supercapacitors, also known as double-layer capacitors, gold capacitors, supercapacitors, or Faraday capacitors, store energy through polarized electrolytes. They are an electrochemical component, but no chemical reaction occurs during their energy storage process. This energy storage process is reversible, and because of this, supercapacitors can be charged and discharged hundreds of thousands of times. At the same time, supercapacitors are a new type of green and environmentally friendly energy storage device (activated carbon), It has superior characteristics such as high efficiency, high current capacity, wide voltage range, wide temperature range, long service life of rewinding, long working life, maintenance free, easy integration, and low cost.
