Product Introduction:
The solar charging system, also known as double-layer capacitors, gold capacitors, or Faraday capacitors, stores energy through polarized electrolytes. It is an electrochemical component, but no chemical reaction occurs during its energy storage process. This energy storage process is reversible, and because of this, supercapacitors can be repeatedly 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), which has extremely high efficiency High current capacity, wide voltage range, wide temperature range, long winding service life, long working life, maintenance free and easy to maintain, simple integration, low cost, and other superior characteristics.
