Recent Advances in Rechargeable Aluminum-Ion Batteries and Considerations for Their Future Progress

Abstract

Owing to their high theoretical capacity and reliable operational safety, nonaqueous rechargeable aluminum batteries (RABs) have emerged as a promising class of battery materials and been intensively studied in recent years; however, a lack of suitable, high-performing positive electrode materials, along with the need for air-sensitive and expensive ionic liquid electrolytes, has significantly hindered the practical use of RABs in large-scale applications. Therefore, we sought to carefully analyze positive electrode materials and the associated electrolytes that have been reported in these battery systems in order to stimulate the design of the next generation of high-performance and low-cost RABs. In this review, we have summarized the electrode materials that have been used in both nonaqueous and aqueous RAB systems and provided a rational classification based on the types of materials used and their respective structures. Additionally, we have reviewed electrolytes employed in RABs and have categorized them according to two main types of applications, either for fixed battery systems or for use in portable devices. A systematic account of recent developments on RABs, with a focus on electrode materials, innovative perspectives, and impending research efforts on future RABs, has been included. Finally, a proposed liquid RAB system is discussed with the aim of solving issues regarding fast-charging and long operational lifetimes, followed by insights into solid RABs for use in both portable and multistructural RAB systems.

Recent developments in conducting polymers: applications for electrochemistry

“…The saturation limit reached a value of 5 M. The acceptable catalytic activity, simplied procurement, and stability of the Cu 2 O/PPy composite indicate that it is a very good electrocatalyst for the oxidation of ethanol. [128][129][130][131]…”

AlCl3‐Saturated Ionic Liquid Anolyte with an Excess of AlCl3 for Al–Graphite Dual‐Ion Batteries

“…In a search for inexpensive, large‐scale stationary storage of electricity, non‐aqueous Al‐graphite dual‐ion batteries (AGDIBs) have attracted recently much attention due to the high natural abundances of their primary constituents, the long cycle life of up to a quarter of a million cycles, the high energy efficiency of 80–90 % and facile manufacturing [1–8] . While recent research efforts on AGDIBs have been mainly focused on the judicious selection of carbonaceous cathode materials, leading to the most notable advances in the performance of AGDIBs, [9–27] the major challenge with such batteries is that they lag behind Li‐ion batteries in theoretical cell‐level energy density.…”

Degradation Behavior, Biocompatibility, Electrochemical Performance, and Circularity Potential of Transient Batteries

“…Conventional secondary batteries based on lithium, [ 39 ] sodium, [ 40 ] aluminum, [ 41 ] magnesium, [ 42 ] or zinc‐ion chemistries [ 43 ] are usually composed of chemically stable carbon nanomaterials/metals/metal oxides as electrodes and current collectors, nondegradable polymers as separators, organic liquids as electrolytes, and the full cell is protected by a metallic casing for high safety assurance. In this context, the potential environmental and human health effects of secondary batteries were studied using life cycle impact assessment, concluding that such batteries can be classified as hazardous due to their excessive contents of lead, cobalt, nickel, copper, chromium, thallium, and flammable electrolytes.…”
