Synergistic effect of 3D current collector structure and Ni inactive matrix on the electrochemical performances of Sn-based anodes for lithium-ion batteries

Biomass-Derived Porous Carbon from Agar as an Anode Material for Lithium-Ion Batteries

“…Furthermore, it is worth mentioning the high cost and negative environmental impact due to its synthesis from fossil carbon sources such as coal and petroleum coke [ 7 ]. Therefore, it is highly desirable to explore alternative negative electrode materials for Li-ions such as tin [ 8 , 9 ], transition metal oxides [ 10 , 11 , 12 , 13 ], silicon [ 14 , 15 ], and others. Although the alternative anodes can provide higher specific capacity, they suffer from substantial volume changes during insertion/extraction of Li-ions causing materials disintegration leading to huge irreversible capacity loss and poor cyclability.…”

Advanced Battery Materials Research at Nazarbayev University: Review

“…al. reported a unique 3D architecture anode fabricated by electrodeposition of ultrathin Ni 3 Sn 4 intermetallic alloy onto a commercially available nickel foam current collector from an aqueous electrolyte [28][29][30][31]. The designed three-dimensional electrode demonstrated a high discharge capacity of 843.75 mAh g -1 during initial cycles and an improved cycle performance over 100 cycles in contrast with the same alloy electrodeposited onto planar substrate (Fig.…”

Preparation of a Ni3Sn2 alloy-type anode embedded in carbon nanofibers by electrospinning for lithium-ion batteries

“…Ni 3 Sn 4 and Ni 3 Sn 2 , with theoretical capacities of ∼725 mA h g −1 and ∼570 mA h g −1 , respectively) demonstrated lower volume expansion and better capacity retention compared to Sn alone. 13–17…”

“…Ni 3 Sn 4 and Ni 3 Sn 2 , with theoretical capacities of 725 mA h g −1 and 570 mA h g −1 , respectively) demonstrated lower volume expansion and better capacity retention compared to Sn alone. [13][14][15][16][17] Enclosing the Sn with carbon is another common way to overcome its volume expansion. This has been implemented in a variety of ways such as encapsulation in hollow-shell, yolkshell, core-shell spheres, core-shell nanotubes/nanobers, suspension in a carbon matrix, etc.…”
