Development of rechargeable cement-based batteries with carbon fiber mesh for energy storage solutions
Journal of Energy Storage(2024)
Abstract
This paper presents the development of novel rechargeable cement-based batteries with carbon fiber mesh for energy storage applications. With the increasing demand for sustainable energy storage solutions, there is a growing interest in exploring unconventional materials and technologies. The batteries featured the carbon fiber mesh, which coated with nickel oxide and iron materials as electrodes and immersed in a cement-based electrolyte, offering a unique approach to energy storage. Experimental investigations, including electrochemical impedance spectroscopy, cyclic voltammetry, charge-discharge cycling, and rate performance assessments, were conducted to evaluate the batteries' performance. Results indicated that the batteries have promising features such as high ionic conductivity of the cement-based electrolyte and stable charge-discharge behaviors over 100 cycles. Cyclic voltammetry curves demonstrated quasi-reversible redox peaks, indicative of battery-type electrochemistry. The rechargeable cement-based batteries exhibited stability in discharge capacity, efficiency, and energy density, surpassing existing literatures on cement batteries, with a maximum energy density of 7.6 Wh/m2. Despite challenges related to efficiency and energy density, this paper envisions the practical applications for the batteries, from powering light sensors to supporting 5G base stations and meeting daily electricity needs. Integration of rechargeable cement-based batteries and clean energy sources holds significant promise for global energy storage solutions. In conclusion, this research provides valuable insights into developing rechargeable cement-based batteries, highlights their potential as sustainable energy storage solutions with opportunities for further optimization and future advancements.
