Rational design and synthesis of sandwich-like reduced graphene oxide/Fe2O3/N-doped carbon nanosheets as high-performance anode materials for lithium-ion batteries

Carbon-based materials and their composites as anodes: A review on lithium-ion batteries

“…Fe 2 O 3 with a nano-size structure provides a high surface area and short diffusion pathway for Li-ions. The conductive carbon matrix can consolidate the nanocompos-ites' integrity and also offers fast transfer paths for the electrons [188]. So far, many attempts have been made to increase the electrochemical performance of Fe 2 O 3 /carbon composites through designing the carbon matrices with various morphologies [189][190][191].…”

Integrated Design of Silkworm‐Chrysalis‐Net‐Like Fe3O4/rGO/Mesoporous Carbon Composites as a High‐Performance Anode Material for Lithium‐Ion Batteries

“…The mesoscopic morphologies formed from the composites of Fe 3 O 4 and carbon materials include spheres, [22,23] octahedrons, [24] lines, [25,26] tubes, [27] flakes, [28] and sandwich structures. [29] In particular, forming a multilayered structure of Fe 3 O 4 , rGO, and a porous carbon layer can endow materials with unique properties. By introducing two-dimensional rGO as a structure-directing agent, the large specific surface area and excellent electrical conductivity can provide an outstanding contact area for the active material.…”

FeCoS2 polyhedral spherical nanoparticle decorated nitrogen doped hollow carbon nanofibers as high-performance self-supporting anodes for K-ion storage

“…1–4 They're currently commonly employed in portable electronic gadgets and alternative energy vehicles. 5–12 The development cost of lithium is fast rising as a consequence of the scarcity of lithium sources and wide and diverse usage, resulting in a rapid increase in the prices of most electrical items and electric cars that employ lithium batteries. 13–15 Most researchers are now turning to the study of potassium, which is similar in nature to lithium, and potassium resources are not only abundant in reserves but also have low development costs.…”

“…The standard hydrogen potential for lithium is −3.04 V, and the standard hydrogen potential for potassium is −2.93 V, with the standard potential of the two being quite close. 10,17…”
