“…Other than graphite, various ordered and disordered carbon structures were also analyzed as electrode active materials for DCBs. [ 7 ] One of the most efficiently performing active materials for lithium‐ion‐based DCBs reported is mesocarbon microbead (MCMB). A dual carbon cell (DCC) having the configuration of MCMB||1 m LiPF 6 in ethyl methyl carbonate/sulfolane||MCMB delivered an energy density of 47.9 Wh kg −1 at 583.6 W kg −1 in a voltage range of 3.0–5.4 V and retained 88.5% of initial capacity after 3000 cycles at 5C rate.…”

This work reports carbon fibers as an electrode material and current collector for dual‐carbon and lithium‐ion batteries. Fully graphitic and semigraphitic carbon fibers undergo anion intercalation beyond 4.5 V versus Li/Li+. Symmetric dual‐carbon full cells using a pitch‐coated fully graphitic carbon fiber mat as both cathode and anode delivers an energy‐density of 276 and 322 Wh kg−1 at 342 W kg−1 power density in the voltage range of 3.0–5.0 and 3.0–5.2 V, respectively. On the other hand, nongraphitic carbon fibers do not exhibit anion intercalation up to 5.2 V and can be used as a current collector. They also possess a larger number of Li+ storage sites in their randomly oriented microstructure when used as an anode. A lithium‐ion full cell with double carbon‐coated C‐LiFePO4 loaded on nongraphitic carbon fiber as a cathode and pitch‐coated nongraphitic carbon fiber as an anode exhibits 202.6 and 75.2 Wh kg−1 energy density at power densities of 46.75 W kg−1 and 11.7 kW kg−1, respectively in 2.0–3.5 V range. This pitch‐coated carbon fiber‐based battery configuration eliminates the need for metal foils and costly fluorinated binders, lowers overall weight of the cell, and is capable of sustaining mechanical stress and thermal shock.

“…For multivalent ion batteries these challenges are even more complex and arise from: i) the lack of suitable high voltage cathodes to accommodate the highly polarizing and slowly diffusing multivalent ions; [65] ii) loss of ionic conductivity from the solidelectrolyte interface (SEI) after the first cycle at the anode; [66] iii) passivation effects and a lack of suitable electrolytes allowing reversible redox reactions. [67] Some of the challenges described above, associated with sluggish kinetics, poor reversibility, low specific capacity ascribed to the large ionic radius of Na/K and/or high charge density of active multivalent ions, could be circumvented by the development of dual [68] or potentially multi-ion [69] systems although potentially in the detriment of the energy density. For a NIB/KIB, a configuration comprising of an optimized hard carbon anode paired with a suitable electrolyte and a graphite cathode allows Na + /K + to intercalate into the hard carbon anode, while the anion from the electrolyte intercalates into the graphitic cathode.…”

Over the past 20 years, a revolution has been seen in battery research culminating with a much‐awaited Nobel Prize in Chemistry in 2019 for the development of Li‐ion batteries. New Li‐ion battery materials have been developed recently with improvements in performance. New Li battery chemistries have also emerged, exhibiting high energy density such as Li‐S, Li‐O2, Li‐metal with solid state electrolytes as well as zero‐excess Li anode metal batteries. This is tremendous progress and batteries are becoming more efficient and cheaper each year. Yet, most research in batteries is entirely focused on performance while the sustainability of all battery components making up the cell, as well as the battery chemistry itself are much overlooked. In this essay some perspectives are discussed and opinion is provided on the advancement of sustainability in battery research.

“…Additionally, the practical feasibility of pre‐sodiation strategies for SICs should be considered as well. To address the above‐mentioned problems above, carbon‐based materials are selected as the anode and/or cathode for SICs, owing to the advantages of low cost, sustainability, nontoxicity, abundant allotropes, and excellent physical/chemical stability [21–22] . Among carbonaceous electrodes of SICs, the key of anode lies in improving the rate capability with sufficient capacity, which is associated with the power density of SICs.…”

Nonaqueous sodium‐ion capacitors (SICs), as a new type of energy storage cell, can potentially achieve high energy‐power densities, long cycling lifespan, and low cost in one device. Given this, developing suitable carbonaceous electrode materials for carbon‐based SICs is of great significance. Unlike lithium‐ion batteries (LIBs) and lithium‐ion capacitors (LICs) that have been successfully commercialized, SICs are still at an early stage. As a result, rational electrode material design for SICs is needed to meet the requirements of electrochemical energy‐storage systems. Carbon materials with a wide range of sources and low toxicity deliver significant potential applications in high‐performance SICs, whether as positive or negative parts. Various carbonaceous electrode materials have been explored and investigated for developing SICs over the past years. This Review firstly introduces the classical and widely used configurations and corresponding energy‐storage mechanism in detail for SICs. Then, recent progress on carbonaceous electrode materials, including cathode and anode materials, are summarized. Finally, the challenges and some suggestions on the future development of carbon‐based SICs are proposed.
