“…Transition metal phosphides (TMPs) have been regarded as one class of burgeoning anode competitors for rechargeable batteries due to their high theoretical capacities, vivid electrochemical activity, and low operating potentials [8–12] . However, as a kind of conversion‐type electrode, most of the TMPs exhibited unsatisfactory energy storage life due to the occurrence of large volume variation during discharge/charge processes [13] .…”

Urchin‐type cobalt phosphide microparticles assembled by nanorod were encapsulated in a graphene framework membrane (CoP@GF), and used as a binder‐free electrode for alkali metal ion batteries. Electrochemical measurements indicate that this membrane exhibits enhanced reversible lithium, sodium, and potassium storage capabilities. Moreover, the energy storage properties of CoP@GF electrodes in alkali metal ion batteries display an order of Li>Na>K. DFT calculations on adsorption energy of CoP surfaces for Li, Na, and K indicated that CoP surfaces were more favorable to transfer electrons to Li atoms than Na and K, and the surface reactivity can be ordered as Li‐CoP>Na‐CoP>K‐CoP; thus, CoP@GF exhibits better storage capacity for lithium. This work provides experimental and theoretical basis for understanding the electrochemical performance of cobalt phosphide‐based membranes for alkali metal ion batteries.

Recently, carbon nanohybrids based on carbon nanomaterials including fullerene, carbon nanotube (CNT), carbon nanofiber (CNF), and graphene have attracted considerable attention in the field of science and technology due to their unique electrical, mechanical, chemical, spectroscopic properties, and high porosities. These nanohybrids not only increase electrical conductivity, but also enhance surface areas, thereby overcoming the limitations of individual carbon nanomaterial for material science and electronic engineering. Herein, the electronic and materials properties of carbon nanohybrids consisting of CNT/graphene, CNT/fullerene, CNT/CNF, and graphene/fullerene for advanced electronic applications are discussed.

One of the main challenges potassium‐ion batteries (PIBs) face is the lack of structurally stable anodes with high reactivity and fast kinetics for reversible potassium insertion/extraction. Herein, nitrogen‐doped carbon nanotubes (N‐CNTs) are synthesized using a straightforward method assisted by a Co‐based catalyst. The as‐synthesized N‐CNTs possess interlayer distances up to 0.38 nm and nitrogen‐doping content of 2.2 at.%. Compared to the undoped CNTs (U‐CNTs), N‐CNTs exhibit a promising initial specific capacity of 568 mAh g−1 at 0.1 A g−1, as well as excellent long‐term cycling performance of 104, 82, and 76 mAh g−1 at a high current of 0.5, 1, and 2 A g−1 for 500 cycles. The cyclic voltammetry (CV) measurements reveal the potassium storage mechanism of N‐CNTs, which combines the major capacitive mechanisms and the secondary diffusion, and successfully avoids inconspicuous voltage plateau. The kinetic analysis of the galvanostatic intermittent titration technique and ex situ X‐ray photoelectron spectroscopy spectra show fast reaction kinetics and low side effects and degradation for the N‐CNTs anodes during the potassiation/de‐potassiation process. This study provides a straightforward method to synthesize heteroatom‐doped carbonaceous anode materials and achieves superior electrochemical properties with cost‐effectiveness and material sustainability.
