“…One strategy is to synthesize nanostructured Fe 3 O 4 . [13][14][15] The nanoscale particle size not only improves the accommodation of the strain but also significantly shortens the length of the diffusion path of Na + . This is critical for Na-ion transport and storage, especially considering the large ionic radius of Na + .…”

Fe3O4 is widely investigated as an anode for ambient sodium‐ion batteries (SIBs), but its electrochemical properties in the wide operation‐temperature range have rarely been studied. Herein, the Fe3O4 nanoparticles, which are well encapsulated by carbon nanolayers, are uniformly dispersed on the graphene basal plane (named Fe3O4/C@G) to be used as the anode for SIBs. The existence of graphene can reduce the size of Fe3O4/C nanoparticles from 150 to 80 nm and greatly boost charge transport capability of electrode, resulting in an obvious size decrease of superparamagnetic Fe nanoparticles generated from the conversion reaction from 5 to 2 nm. Importantly, the ultra‐small superparamagnetic Fe nanoparticles (≈2 nm) can induce a strong spin‐polarized surface capacitance effect at operating temperatures ranging from −40 to 60 °C, thus achieving highly efficient Na‐ion transport and storage in a wide operation‐temperature range. Consequently, the Fe3O4/C@G anode shows high capacity, excellent fast‐charging capability, and cycling stability ranging from −40 to 60 °C in half/full cells. This work demonstrates the viability of Fe3O4 as anode for wide operation‐temperature SIBs and reveals that spin‐polarized surface capacitance effects can promote Na‐ion storage over a wide operation temperature range.

The present study provides a facile one‐pot pyrolysis strategy to prepare serial nitrogen‐doped (N‐doped) metal/carbon composites derived from six types of metal ethylenediaminetetraacetic acid (EDTA‐M, M = Co, Cu, Mn, Fe, Mg, and Ca). N‐doped Co/C composite integrated carbonaceous with magnetic components to attain dielectric‐magnetic double loss mechanisms. The minimum reflection loss and effective absorption bandwidth reached −57.6 dB at 1.75 mm and 4.64 GHz at 1.52 mm, respectively. The electromagnetic simulation further confirms that the dissipation ability increases with the improvement of carbonization temperature. Results show that altering the metal species of precursors can significantly improve the electrochemical performance of the composites using the identical strategy. N‐doped Cu/C composite performed a maximum specific capacitance of 2383.3 F g−1 at 0.5 A g−1−1, and maintained 86.3% cycling stability at 20 A g−1 after 5000 cycles. The energy density of a symmetrical two‐electrode configuration achieved 350.13 Wh kg−1 at a power density of 4000.04 W kg−1. Density functional theory calculations indicate that nitrogen dopants cause faster ion transport and stronger adsorption capacity. Moreover, the bifunctionality of other composites types are also systematically characterized.
