“…Based on the above structure characterization, we could find that the mesoporous nanowires are uniformly coated with the phosphorus and nitrogen co‐doped carbon layer, which is beneficial for the continuous electronic conduction. The mesoporous nanowire with high surface area would allow feasible electrolyte wettability and rapid diffusion toward the active sites with less resistance, relieve the stress caused by the huge volume changes during electrochemical processes, thus boosting the capacitive performance and lifespan of electrode materials …”

The binary transition metal oxides have attracted great attention because of their considerable energy and power densities. However, they suffer from low reaction kinetics and large volume change, limiting their practical energy applications. The construction of a mesoporous structure with a large surface area, the development of a carbon matrix, as well as heteroatom doping can effectively overcome the above challenges. Herein, the synthesis of phosphorous‐containing Fe2VO4/nitrogen‐doped carbon mesoporous nanowires (P‐Fe2VO4/NCMNWs) is reported. In this unique structure, the atomic‐level P‐doping could increase the conductivity of Fe2VO4 by reducing its band gap, which is confirmed by DFT calculations. Furthermore, the phosphorus can covalently “bridge” the carbon layer and Fe2VO4 through P−C and Fe−O−P bondings. As a result, this anode material exhibits a high capacity (1002 mA h g−1 at 0.5 A g−1 after 250 cycles), excellent rate performance (448 mA h g−1 at 10 A g−1), and prominent long‐term cycling stability (533 mA h g−1 at 5 A g−1 after 500 cycles, 364 mA h g−1 at 10 A g−1 after 1000 cycles). All of these attractive features make the P‐Fe2VO4/NCMNWs a promising electrode material for high‐performance lithium‐ion batteries.

“…Analogously, morphology design and the introduction of a conductive phase that accommodates volume changes, like amorphous carbon and graphene, can largely alleviate the volume changes of SnS 2 in charge and discharge processes (Zhuo et al, 2012). Since the microstructure of layered SnS 2 materials has some resemblance to 2D graphene, the combination of them is more compatible than other dissimilar materials like SnO 2 , Sn, and Si (Bin et al, 2019). Few-layer SnS 2 /graphene hybrid materials synthesized using L-cysteine as a ligand in the solution-phase method have been reported by Chang et al which can deliver a reversible specific capacity of 920 mAh/g at a current density of 100 mA/g (Chang et al, 2012).…”

Tin and Tin Compound Materials as Anodes in Lithium-Ion and Sodium-Ion Batteries: A Review

et al. 2020

View full text Add to dashboard Cite

Tin and tin compounds are perceived as promising next-generation lithium (sodium)-ion batteries anodes because of their high theoretical capacity, low cost and proper working potentials. However, their practical applications are severely hampered by huge volume changes during Li + (Na +) insertion and extraction processes, which could lead to a vast irreversible capacity loss and short cycle life. The significance of morphology design and synergic effects-through combining compatible compounds and/or metals together-on electrochemical properties are analyzed to circumvent these problems. In this review, recent progress and understanding of tin and tin compounds used in lithium (sodium)-ion batteries have been summarized and related approaches to optimize electrochemical performance are also pointed out. Superiorities and intrinsic flaws of the above-mentioned materials that can affect electrochemical performance are discussed, aiming to provide a comprehensive understanding of tin and tin compounds in lithium(sodium)-ion batteries.

“…[18] The large volume changes during potassiation and depotassiation are the main disadvantage of the alloy-and conversion-based materials. [19][20][21][22] In contrary, carbonaceous materials are among the best potential anodes owing to their good conductivity and high thermal stability. Carbonaceous materials such as hard carbon, graphene, carbon nanotubes, and graphite have been investigated as anode materials for PIBs.…”

Potassium-ion batteries (PIBs) are promising alternative to Lithium-ion batteries (LIBs) owing to their economic merits. However, the PIBs have not met suitable anode materials comparable to graphite in LIBs. We synthesised an orange peelderived mesoporous carbon (OPDMC) as a potential anode material for high performance PIBs via facile one-step carbonisation with self-activation from waste orange peel. The OPDMC-1000, which were carbonised at 1000°C, exhibited impressive initial discharge/charge capacities of 408/224 mAh g À 1 at 30 mA g À 1 and retained the reversible capacity of 208.57 mAh g À 1 over 100 cycles. Even after 2000 and 3000 cycles at specific currents of 200 and 500 mA g À 1 , it maintained the reversible capacities of 150.37 and 112 mAh g À 1 , respectively. A full cell employing the OPDMC exhibited an initial reversible discharge capacity of 185.32 mAh g À 1 at 50 mA g À 1 with capacity retention of 71.60 % after 50 cycles, indicating its practical applicability.
