A tremella-like Mo and N codoped graphitic nanosheet array supported on activated carbon (Mo2C-MoC/AC-N) is prepared via in situ carbonization of nitrogen-rich cobalt phthalocyanine nanoparticulates anchored on activated carbon as a high-performance anode for potassium-ion batteries. The nanosheets about 5 nm thick are uniformly distributed on the surface of activated carbon for fast K-ion intercalation, and the abundant micropores in activated carbon provide additional adsorption sites of potassium ions, forming a three-dimensional architecture for potassium storage. The 3.9 atom % Mo in Mo2C-MoC/AC-N is in the form of Mo2C and MoC flakes (around 1:1) attached to the graphitic nanosheets. X-ray diffraction (XRD) analysis revealed that the reaction with Mo2C (forming K2C) happens mainly at 0.8–0.4 V, while the reaction with MoC (forming K2C) occurs primarily at 0.4–0.01 V. The N doping (9.6 atom %) causes an interlayer spacing expansion of 0.3 Å in the graphitic nanosheets, beneficial to the potassium-ion insertion reaction to form KC8 at 0.4–0.01 V. The Mo2C-MoC/AC-N anode exhibits a capacity of 457.5 mA h g–1 at a current density of 0.05 A g–1 and an excellent capacity of 144.4 mA h g–1 at a high current of 5 A g–1 with a capacity loss rate of 0.49‰ per cycle.

Efficient catalysts for the reduction reaction of SOCl2 are desired for lithium/thionyl chloride batteries with high and stable voltage. In this work, iron phthalocyanine particulates fixed on activated carbon substrates (FePc/AC) are synthesized by an in situ solid approach under the temperatures lower than 300 °C. U–T curves, the value distance to the average U, dU/dT via mathematical differentiation and numerical analysis were employed to investigate to the catalytic reduction of SOCl2 systematically. The U–T curve of the battery containing the FePc/AC displays almost perfect rectangle profile. The average voltage of the battery contains the FePc/AC is 3.00 V, 0.21 V higher than that without the catalysts. After discharge, the surface of the carbon cathode containing FePc/AC displays a well-constructed loose morphology composed of LiCl nanoparticles around 100 nm in diameter. The inside of carbon cathode shows a dense morphology with a mount of nano holes around 50 nm, indicating that the formed LiCl permeates into the interior of the carbon cathode, attributing to that the FePc/AC nanocomposite catalysts facilitate the reduction of SOCl2, leading the formation loose LiCl film in nano scale for electrolyte SOCl2 and the formed LiCl diffusion.

Lithium/thionyl chloride (Li/SOCl2) primary batteries are appealing power solutions because of their remarkable electrochemical performances. However, their mass applications are hindered by the challenges in sustainability, cost and safety concerns owing to the employed Li chemistry. Here, magnesium (Mg) chemistry is shown as a promising alternative through synergistic optimization of electrolyte solvation and electrode reaction kinetics. The first Mg/SOCl2 primary battery yields surprisingly high specific capacities up to ≈14 000 mAh g−1 at a decent discharge voltage of ≈1.67 V, which outperforms the state‐of‐the‐art Mg‐based primary batteries. In addition, it retains almost 100% of the original capacity after 20‐day reservation. The impressive battery performances are originated from the stabilized MgCl2 formation on high‐surface‐area carbon cathode and suppressed Mg anode corrosion via the Mg‐induced solvation effect. Mg/SOCl2 primary batteries are promising candidates for low‐cost and recyclable power supplies, and they thus open new avenues for the development of sustainable battery chemistries.
