Aging Mechanism and Models of Supercapacitors: A Review

Abstract

Electrochemical supercapacitors are a promising type of energy storage device with broad application prospects. Developing an accurate model to reflect their actual working characteristics is of great research significance for rational utilization, performance optimization, and system simulation of supercapacitors. This paper presents the fundamental working principle and applications of supercapacitors, analyzes their aging mechanism, summarizes existing supercapacitor models, and evaluates the characteristics and application scope of each model. By examining the current state and limitations of supercapacitor modeling research, this paper identifies future development trends and research focuses in this area.

Developments in conducting polymer-, metal oxide-, and carbon nanotube-based composite electrode materials for supercapacitors: a review

“…Ma et al investigated the aging behavior of SCs with an increase in charging/discharging cycles. 260 This aging behavior (deterioration) of the electrode surface with an increase in the discharge/charge cycle of SCs was based on the nature and composition of electrode materials used in SCs. The performance of single-material-based electrodes was found to be better with an increase in cycle life as compared to composite electrode material-based SCs.…”

Applications of Nanomaterials for Enhanced Performance, and Sustainability in Energy Storage Devices: A Review

“…Carbon, metal oxides, separator and electrolyte used to design the supercapacitor and carbon nanotubes is in used progressively. [13,43,44] They have a power density that is significantly higher than that of batteries and fuel cells (102-104 W/ Kg) and a lengthy life cycle, or extended charge-discharge cycles. It is widely recognised that supercapacitors (SCs) can keep their improved performance, larger capacity, and reduced internal resistance for up to a million deep charging and discharging cycles at high speeds.…”
