Comparative Analysis of Supercapacitors vs. Batteries

Abstract

This paper presents a comparative analysis of supercapacitors and batteries as energy storage technologies, focusing on key performance metrics such as energy storage capacity, power output, efficiency, and charge/discharge cycles. Supercapacitors are known for their rapid charge and discharge capabilities, high power density, and longevity, making them ideal for applications requiring quick bursts of energy. Conversely, batteries, particularly lithium-ion, offer significantly higher energy density, enabling them to store more energy in a compact form factor, but they suffer from longer charging times and limited cycle life. This study highlights the trade-offs between the two technologies, providing insights into their suitability for various applications, from consumer electronics to renewable energy systems. The findings suggest that while supercapacitors excel in scenarios demanding high power and durability, batteries remain the preferred choice for applications requiring higher energy storage capacity. The analysis underscores the importance of selecting the appropriate energy storage solution based on specific application requirements.
