A review of the design and strategies for photoassisted rechargeable metal-ion batteries

Abstract

In the quest to combat environmental pollution and reduce reliance on fossil fuels, renewable energy sources have garnered significant attention. Among these, solar energy stands out due to its green, clean, and virtually limitless supply. However, solar cells, while efficiently converting solar energy into electricity, cannot store this energy, making them impractical in the absence of sunlight. This challenge has spurred the development of photoassisted rechargeable batteries (PARBs), which combine the energy-harvesting capabilities of solar cells with the storage capacity of batteries. PARBs enable the direct conversion and storage of solar energy into chemical energy, enhancing energy efficiency and offering longer cycle life, stability, and reduced energy loss compared with traditional devices. This review provides a comprehensive overview of PARB technologies, including recent advancements in metal-ion-based systems such as Li, Na, K, Zn, Mg, and Al. Key strategies to improve PARB performance are explored, including structural and defect engineering, electrolyte modification, and surface coating techniques. Additionally, challenges related to interfacial issues, charge carrier recombination, and electrolyte degradation are discussed alongside proposed solutions. By addressing these challenges and highlighting the potential of PARBs, this review aims to inspire further research and innovation in the field, contributing to the future of sustainable energy storage technologies.
