Oriented wrinkle textures of free-standing graphene nanosheets: application as a high-performance lithium-ion battery anode

Effect of Pitch Coating on SiOx Alloy/Spherical Artificial Graphite Composites as Anode Materials for Lithium‐Ion Batteries

“…This is considered the effect of carbon coating layer preventing direct contact between electrolyte and SiOx [23] . Moreover, it was confirmed that P@SiOx‐10@G‐1100 was the most stable due to the well‐developed crystal carbon structure resulting from the highest carbonization temperature as shown in Figure S2 [31,52–54] . The data of this study and other representative studies are shown in Table S4 to compare the electrochemical properties.…”

“…In Figure 5e, P@SiOx‐10@G‐900 (97.8 % at 1200/200 mA g −1 ) and P@SiOx‐10@G‐1100 (97.6 % at 1200/200 mA g −1 ) showed relatively outstanding rate capabilities, as shown in Table S3, and P@SiOx‐10@G‐700 showed the impressive lithium‐ion diffusion rates, as displayed in Figure S4. With higher carbonization temperature, the rate capability increased [31,52–54] . In addition, the formation of carbon coating layer on the surface of SiOx is considered to have an positive effect on the electrochemical stability.…”

“…With higher carbonization temperature, the rate capability increased. [31,[52][53][54] In addition, the formation of carbon coating layer on the surface of SiOx is considered to have an positive effect on the electrochemical stability. Figure 5c, f shows the initial charge and discharge profiles and rate capabilities according to the SiOx alloy content.…”

Control of cyclic stability and volume expansion on graphite–SiOx–C hierarchical structure for Li-ion battery anodes

“…Prelithiaion strategy, to compensate for irreversible Li loss before full-cell fabrication, could be achieve more than 90% of ICE. [45][46][47][48] This is expected to be helpful in practical applications in the future.…”

A recent trend: application of graphene in catalysis

“…Apart from having desirable properties for catalysis, graphene has also been identified to possess properties which are useful in a wide range of applications [25,26] and technologies, thus prompting extensive research on graphene as well as its possible applications. The large surface area and remarkable electrical conductivity of graphene also promote its application in electrochemical reactions which, in turn, are applied in oxygen reduction reactions (ORRs) in membrane fuel cells as well as in hydrogen generation during water splitting.…”
