“…Specifically, transitional‐metal oxides (TMOs) have attracted great attention because of the much higher capacity than that of conventional graphite (372 mAh g −1 ), widespread availability, intrinsically enhanced safety, and low cost . In principle, TMOs store Li through a conversion reaction, in which they are reduced to metallic nanocrystals dispersed in a Li 2 O matrix upon lithiation and are then reversibly restored to the initial state after delithiation . The multi‐electron redox reaction with the fully utilized oxidation state endows TMOs with high specific capacities of 600–1000 mA h g −1 .…”

One promisinga nd economic step towards technological advancements in Na-ion andL i-ion batteries is to develop versatile electrode materials for alkali-metal storage. Transitionalmetal oxidesa re appealing candidates, owing to their intrinsically low cost, high capacity,a nd enhanced safety. However, they generally showpoor activity and as hort lifespan in practical use. Herein, we report the fabrication of av ersatile longlife, high-rate anode material for Li/Na storage by strongly binding ultrafineF e 3 O 4 quantumd ots onto hybrid carbon nanosheets. Such nanocomposites are advantageous for inhibiting particlea ggregation,r educing ionic diffusion pathways, and enabling fast accessibility to electrolyte ions across large electrode-electrolyte interfaces. They exhibit al ong lifetime of 1000 cycles, high capacities, and exceptional high rate capabilities towards alkali-metal storage, highlighting great promise in high-energya nd high-power energy applications.[a] S.

Kohlenstoff‐Aerogele, die typischerweise mit Sol‐Gel‐Chemie hergestellt werden, bestehend aus einzigartigen dreidimensionalen Netzwerken von nanometergroßen Partikeln und weisen faszinierende physikalische Eigenschaften mit großen Anwendungspotenzialen auf. Um die praktischen Anwendungen voranzubringen, ist es dringend notwendig, effiziente und kostengünstige Verfahren zur Herstellung von hochleistungsfähigen Kohlenstoff‐Aerogelen in großem Maßstab zu entwickeln, und das vorzugsweise auf eine nachhaltige Art und Weise. Im Jahr 2012 wurde über zwei neue Klassen von Aerogelen aus Kohlenstoff‐Nanofasernetzwerken (CNF) berichtet. Sie wurden aus einem aus Biomasse gewonnenen Vorläufer durch Chemosynthese (d. h. templatgesteuerte hydrothermale Karbonisierung von Kohlenhydraten) und Biosynthese (d. h. Verwendung von bakterieller Cellulose als Vorstufe) hergestellt. Dieser Aufsatz gibt einen kritischen Überblick über dieses neuartige Gebiet und beschränkt sich dabei auf die Synthesestrategien der Kohlenstoffnanofaser‐Aerogele und ihre hervorragenden physikalischen Eigenschaften. Ebenso besprechen wir das Potenzial für die multifunktionale Anwendungen der beiden neuartigen Kohlenstoff‐Aerogele und ihrer Nanokomposite und zeigen die Herausforderungen und die zukünftigen Möglichkeiten in diesem spannenden Gebiet auf.

Iron oxides, such as hematite (α-Fe2O3), maghemite (γ-Fe2O3), and magnetite (Fe3O4), have been considered as alternative anode materials for lithium-ion batteries (LIBs) due to their high theoretical capacity, abundant reserves, low cost, and non-toxicity. However, their practical application has been hampered by the large volume expansion, which leads to rapid capacity fading. Nanostructure engineering has been demonstrated to be an effective avenue in tackling the volume variation issue and boosting the electrochemical performances. Herein, recent advances on nanostructure engineering of iron oxides for lithium storage are summarized. These nanostructures include 0D nanoparticles, 1D nanowires/nanorods/ nanofibers/nanotubes, 2D nanoflakes/nanosheets, as well as 3D porous/hollow/hierarchical architectures. The structureelectrochemical performance correlations are also discussed. It is believed that the performance optimization strategies summarized here might be extended to other high-capacity LIB anode materials.
