Synthesis and Characterization of Al based flexible electrode for Aluminum Ion Battery

Abstract

This study aims to resolve embedded limitations of conventional aluminium-ion batteries (AIB) through development of flexible and robust aluminium-derived electrodes that can serve potential in affordable, eco-friendly, and high-performance energy storage frameworks. Due to the low cost, non-toxicity, high theoretical capacity, long cycle life, and the large variety of available cathode materials, aluminium-ion batteries have received increasing attention as an attractive alternative to Li-ion batteries. However, its spontaneous brittle nature prevents it from practical application in flexible and light-weight applications. To solve this problem, developing research is steering toward the reinforcement of aluminium with lignocellulose (LC) Fibers to form a composite matrix that maintains the electrochemical properties of aluminium, yet introduces mechanical conformability and structural durability. The aluminium based composite electrodes were prepared and optimized with different synthetic methods including sol-gel process, hydrothermal synthesis, and microwave assisted method. Among them, the microwave-assisted approach could result in more efficient homogeneous and adverse. Structurally stable electrodes with greater efficiency. The resultant LC Fiber reinforced Al composites electrodes exhibited superior mechanical properties without compromising their electrochemical performance, which brings them one step closer to the potential applications in wearable and flexible energy storage. Beyond proving the conception of LC Fiber-integrated flexible aluminium-ion batteries of future, this work reports on a new processing architecture based on a microwave-IR hybrid radiation technology for sustainable and scalable manufacture of electrodes.
