- DTArticle
- ABAluminum-ion batteries (AIBs) offer several advantages over lithium-ion
batteries including safety, higher energy density, rapid charging,
reduced environmental impact, and scalability. In the case of anodes,
interest in electropositive metals for rechargeable batteries,
particularly aluminum, has surged due to their abundance (8.23 wt % in
earth's crust) and high volumetric capacity (8050 mAh g-1). Concerning
cathodes, various materials are explored for AIBs, including transition
metal oxides (e.g., V2O5, MoO2), sulfides (e.g., SeS, CuS, and MoS),
carbon, and conductive polymers. Among these, carbon remains the ideal
choice due to its work function compatibility with aluminum, stability,
high conductivity, anion intercalation capability, and scalability,
despite the low intercalation capacity of graphite and its limiting
energy density and limiting energy density. In this review, we elaborate
the current progress and challenges in utilizing different carbon
materials for aluminum and chloride ion intercalation realized since
2015, focusing on graphite, carbon composites, carbon nanotubes (CNTs),
and other nanostructured carbons. We analyzed the trade-offs and
challenges in optimizing these electrodes, including balancing energy
density, cycling stability, addressing structural degradation, and
managing electrode swelling. The focus of this review was placed on the
strategies to overcome these hurdles, such as the utilization of
nanoscale composites, conductive additives, and development of
hierarchical architectures, along with recent advancements in their
synthesis methods, different electrode morphology, and functional
coatings to enhance the stability of carbon. Investigation into
high-energy cathodes leveraging triple-ion intercalation chemistry (Al3+
ion) holds promise for advancing sustainable battery technology. - Z99
