142920 - Development of Rechargeable Carbon Fiber Mesh-Cement Batteries for Energy Storage Solutions 

Inspired by traditional nickel-iron batteries and utilizing the unique properties of cement, this article introduces an innovative approach to energy storage in building materials and explores the development and characterization of alkaline rechargeable batteries for integration into cement-based structures.Specifically, the method involves plating carbon fiber mesh with redox-active nickel-iron material and embedding it within a cement-based electrolyte.Experimental investigations encompassing electrochemical impedance spectroscopy, cyclic voltammetry, charge-discharge cycling, and rate performance assessments were conducted to evaluate the battery's performance. Results indicate promising features such as high ionic conductivity of the cement-based electrolyte and stable charge-discharge behaviors over 100 cycles. Cyclic voltammetry curves demonstrate quasi-reversible redox peaks, indicative of battery-type electrochemistry. The carbon fiber mesh-cement battery exhibits stability in discharge capacity, efficiency, and energy density, surpassing existing literature on cement batteries, with a record-setting maximum energy density of 7.6 Wh/m² . Despite challenges related to efficiency and energy density, the paper envisions practical applications for the battery, ranging from powering light sensors to supporting 5G base stations and meeting daily electricity needs. Integration of cement batteries with clean energy sources holds significant promise for global energy storage solutions. In conclusion, this research provides valuable insights into developing rechargeable cement batteries, highlighting their potential as sustainable energy storage solutions with opportunities for further optimization and future advancements.
