### Detailed Explanation of Supercapacitors---Analysis of Key Enterprises Time: 2026-07-31 11:28:45 Content: Supercapacitors—Product Categories. Supercapacitors are special capacitors with performance between ordinary capacitors and rechargeable batteries, possessing the rapid charge/discharge characteristics of capacitors and the energy storage characteristics of batteries. The capacitance of supercapacitors reaches the farad level, which is hundreds to even millions of times that of traditional capacitors. According to the working principle, supercapacitors can be divided into three categories: electric double-layer capacitors (EDLC), faradaic pseudocapacitors, and hybrid supercapacitors (HUC). EDLCs use porous carbon electrode/electrolyte interfaces for double-layer energy storage, operate in the temperature range of -40°C to 70°C, have a cycle life of more than 1 million cycles, and have achieved commercial application, making them the mainstream of current supercapacitor applications.…
