Facile synthesis of CoSnO3/Graphene nanohybrid with superior lithium storage capability

Significant impact of 2D graphene nanosheets on large volume change tin-based anodes in lithium-ion batteries: A review

“…6(c)), which supplied 2D electronically conducting networks for the nanoparticles. As a result, the composites exhibit a charge capacity as high as 649 mAh g À1 in the 50th cycle as well as excellent high-rate cycling stability, which is better than that of pure CoSnO 3 [223], demonstrating the superior advantage of using a GNS matrix in stannate anodes.…”

“…Among these attempts, GNSs provide a significant improvement to the electrochemical properties of the composites. Recently, via a facile in situ solvothermal route, a CoSnO 3 /GNS nanohybrid was designed [223]. CoSnO 3 nanoparticles were distributed on the surface of GNSs (see Fig.…”

Design and Synthesis of Spherical Multicomponent Aggregates Composed of Core–Shell, Yolk–Shell, and Hollow Nanospheres and Their Lithium‐Ion Storage Performances

“…During the first discharging of the three types of microspheres, the reduction peak observed at 1.2 V is attributed to the formation of a solid electrolyte interface (SEI) . The broad reduction peak observed at around 0.9 V in the first scan of the three samples can be ascribed to the formation of metallic Sn and Co nanograins and amorphous Li 2 O through the reduction of CoSnO 3 –Co 3 O 4 . The broad reduction peak observed below 0.5 V in the first cathodic step was attributed to the conversion of Sn–Sn 2 Co 3 mixed alloy and metallic Sn formed through the reduction of CoSnO 3 into Li x Sn and Co nanocrystals, suggesting that Co was separated from the Sn 2 Co 3 alloy during the first lithiation .…”

3D Graphene Encapsulated Hollow CoSnO3 Nanoboxes as a High Initial Coulombic Efficiency and Lithium Storage Capacity Anode

“…In the anodic sweep, the distinct oxidation peak centered at 0.56 V relates to the dealloying reaction of Li x Sn alloys . The peaks located at 1.09 and 1.73 V correspond to the oxidation reactions of Sn to SnO 2 and the one nearby 2.06 V relates to the oxidation reaction of Co to CoO . This suggests that CoSnO 3 cannot be achieved during delithiation process.…”
