A Comparative Analysis of Supercapacitors and Batteries as Energy Storage Devices

Abstract

This paper presents a comprehensive comparative analysis of two prominent energy storage technologies, namely supercapacitors and batteries. Energy storage plays a vital role in modern-day applications, ranging from portable electronics to electric vehicles and renewable energy systems. Supercapacitors and batteries are pivotal players in this field, each offering distinct advantages and disadvantages. This paper provides an overview of the underlying principles and mechanisms governing supercapacitors and batteries. Supercapacitors, based on electrostatic energy storage, boast high power density and long cycle life, making them suitable for applications requiring rapid charge and discharge cycles. Conversely, batteries employ chemical reactions for energy storage, granting them higher energy density and versatility across various applications.
