“…Electrochemical impedance spectroscopy (EIS) was employed to analyze the impedance changes of the Mg-CO 2 batteries with a Mo 2 C-NDs@CNF cathode at different stages of the chargedischarge test. [56][57][58][59][60][61][62] After discharge, the cathode's charge transfer resistance experiences a substantial increase due to the formation and deposition of discharge product layer with poor conductivity on the electrode's surface (Figure 3g,h and Tables S1 and S2 (Supporting Information)). [63][64][65] Conversely, the decrease in electrode R ct (value obtained from EIS fitting using ZView) observed after charge corresponds to the decomposition of the discharge products.…”

The widespread acceptance of nonaqueous rechargeable metal–gas batteries, known for their remarkably high theoretical energy density, faces obstacles such as poor reversibility and low energy efficiency under high charge–discharge current densities. To tackle these challenges, a novel catalytic cathode architecture for Mg–CO2 batteries, fabricated using a one‐pot electrospinning method followed by heat treatment, is presented. The resulting structure features well‐dispersed molybdenum carbide nanodots embedded within interconnected carbon nanofibers, forming a 3D macroporous conducting network. This cathode design enhances the volumetric efficiency, enabling effective discharge product deposition, while also improving electrical properties and boosting catalytic activity. This enhancement results in high discharge capacities and excellent rate capabilities, while simultaneously minimizing voltage hysteresis and maximizing energy efficiency. The battery exhibits a stable cycle life of over 250 h at a current density of 200 mA g−1 with a low initial charge–discharge voltage gap of 0.72 V. Even at incredibly high current densities, reaching 1600 mA g−1, the battery maintains exceptional performance. These findings highlight the crucial role of cathode architecture design in enhancing the performance of Mg–CO2 batteries and hold promise for improving other metal–gas batteries that involve deposition–decomposition reactions.

Solid polymer electrolytes (SPEs) are promising candidates for next-generation energy storage because of their excellent mechanical properties, weather resistance and easy processing. They are better than those of inorganic solid electrolytes (ISEs). Moreover, compared with liquid electrolytes, SPEs also perform a better thermal stability. However, the practical application of SPEs has been impeded by the interphase issues of electrodes/SPEs, especially, the high-capacity cathodes/SPEs interphase in a high energy density battery system. Here we review the key characteristics of SPEs and the interphase issues of high-voltage cathode/SPEs, including the poor interphase contact and interphase instability. In addition, we further analyze the main factors that lead to the serious interphase problems between highvoltage Ni-rich oxide cathodes and SPEs. The effective strategies to solve these problems are also summarized. Finally, we propose a prospect for the improvement of high-voltage Ni-rich cathode/SPE interphase, which provides a guideline for future research on solid Li batteries.

“…Additionally, they have a low self-discharge rate, allowing them to hold their charge for extended periods of time. Furthermore, these batteries are highly efficient when it comes to fast charging and discharging energy. − Despite their promise, limited specific capacity and potential of commercial anodes like graphite hinder its performance and require innovative solutions.…”

The drastic volume expansion and dendrite growth of lithium metal anodes give rise to poor electrochemical reversibility. Herein, ZnO, N dually doped nanocages (c-ZNCC) were synthesized as the host for lithium metal anodes using the zeolitic imidazolate framework-8 (ZIF-8). The synthesis is based on a two-step core@shell evolution mechanism, which could guide lithium deposition rapidly and offer a fast lithium-ion diffusion during the cycling process. Benefiting from the unique design, the as-obtained c-ZNCC can render a record short lithium infusion as low as 1.5 s, a stable lithium stripping/plating capability as long as 3000 h, and a voltage hysteresis of 95 mV when cycling at 10 mA cm −2 to 10 mA h cm −2 . A low Tafel slope of 3.45 mA cm −2 demonstrates the efficient charge transfer of c-ZNCC-Li, and the galvanostatic intermittent titration technique measurement shows high diffusion coefficient of c-ZNCC-Li during the charging process. In addition, the LNMO||c-ZNCC-Li cell exhibits a capacity retention as high as 93.7% at 1 C after 200 cycles. This work creates a new design for deriving nanocages with dual lithiophilic spots using a metal− organic framework and carbon cloth for favorable Li metal anodes.
