“…Figure 5 a shows the CV curve of MXene/PP cell at scanning rate of 0.1 mV/s between 2.8 and 4.5 V. The MXene/PP cell performs three peak couples related to phase transition reactions of H1↔M (hexagonal to monoclinic), M↔H2 (monoclinic to hexagonal), and H2↔H3 (hexagonal to hexagonal). Note that the peak related to M↔H2 became weak, which was corresponding to the previous work [ 36 ]. Figure 5 b displays the cycling performance of the coin cells assembled with PP and an MXene/PP (shorten as PP and MXene/PP cell from here) separator at a current density of 0.5 C. After 100 cycles, the coulombic efficiency of MXene/PP cell was still close to a relatively high value of almost ~100% with little change.…”

“…Obviously, the MXene/PP displayed greatly effects on the cycle stability of NCM811 cathode. According to our previous work [ 35 , 36 ], the cycling improvement of MXene/PP cell should be assigned to the MXene attached on the surface, which can offer more deformation space for the volume expansion of NCM811 during the charging–discharging process and prohibits the irreversible Ni/Co/Mn elements migration via absorption process [ 36 ].…”

“…Compared with ordinary PP cell, the MXene/PP cell showed enhancement on the discharge capacity and First Efficiency. Considering the cells belonging to constant current and constant voltage mode (CC-CV), we suggest that the extra capacity of NCM811 in the MXene/PP cell should be attributed to the intercalation/store of lithium ions between the layered MXene on the surface of PP [ 36 ]. As discussed before, the MXene/PP discharge capacities at the 20th, 40th, 60th, 80th, and 100th cycle were 179.7, 179.2, 179.5, 169.3, and 166.2 mAh/g, respectively.…”

“…Moreover, the MXene/PP cell still maintained a certain stability during the subsequent charging and discharging process. This may be attributed to two-dimensional structure channel of MXene material, which could accelerate ion transmission and MXene improve the stability of the ternary NCM811 material [ 36 ].…”

“…The modified membranes rarely involve improving the electrochemical performance of the currently practical nickel-rich NCM811, such as its safety and stability concerns. Recently, we found that the few-layer and rod-like MXene (Ti 2 C 3 T x ) as a multifunctional additive can significantly enhance the mechanical properties, cycling performance, and rate capability of Li/NCM811 cells [ 36 ]. Therefore, taking into account the important position of the separator in LIBs and previous work, we believe that the current dilemma of NCM811 may be solved by modifying the commercial PP separator with MXene load.…”

In this work, a few-layer MXene is prepared and sprinkled on a commercial polypropylene (PP) separator by a facile spraying method to enhance the electrochemistry of the Ni-rich LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode. Scanning electron microscope (SEM) and X-ray diffraction (XRD) are used to characterize the morphology and structure of MXene. Fourier transform infrared spectroscopy (FT-IR) and a contact angle tester are used to measure the bond structure and surface wettability PP and MXene/PP separator. The effect of the MXene/PP separator on the electrochemical performance of ternary NCM811 material is tested by an electrochemical workstation. The results show that the two-dimensional MXene material could improve the wettability of the separator to the electrolyte and greatly enhance the electrochemical properties of the NCM811 cathode. During 0.5 C current density cycling, the Li/NCM811 cell with MXene/PP separator remains at 166.2 mAh/g after the 100 cycles with ~90.7% retention. The Rct of MXene/PP cell is measured to be ~28.0 Ω. Combining all analyses results related to MXene/PP separator, the strategy by spraying the MXene on commercial PP is considered as a simple, convenient, and effective way to improve the electrochemical performance of the Ni-rich NCM811 cathode and it is expected to achieve large-scale in high-performance lithium-ion batteries in the near future.

Every once in a while, a revolutionary technological development arises, which leads to a significant change in the way to approach research and push development efforts. The appetite for new technology compels society to look for game‐changing materials, that can transform the industry and make advances. Sustainable energy production is paramount to addressing the climate crisis, and energy generation and storage play an important role in the development of self‐powered microelectronic devices. The 2D materials, MXenes have emerged as promising candidates for energy and other applications owing to their inherent electrical merits, high specific surface area, and tunable properties. Particularly, in the context of additive and interfacial materials for perovskite solar cell fabrication and utilization as additives in secondary batteries, this review delves into the application of MXenes in such devices. The protocols of MXenes and their nanostructures tailoring toward such applications and, the underlying mechanism is uncovered.

fuels), such as excessively high temperatures, heavy downpours, severe floods, and droughts. As a response to the climate change, a global coalition for carbon neutrality is committed to be built by 2050 to maintain the sustainability of the global development. An imminent transition of the energy structure from traditional fossil fuels to the renewable energy sources, such as wind, solar, and tide is of great urgency. Due to the intermittent nature of these resources, energy-storage devices, especially the electrochemical energy-storage technologies, are of great significance in ensuring the stability and quality of the energy output. Lithium-ion batteries (LIBs) have been dominating the energy-storage market since its first commercialization in the 1990s. [1] They are currently widely applied in consumable electronics, electric vehicles, and grid-scale energy storage. [2] Yet more concerns have been raised regarding the scarcity and price of the lithium resources in recent years. Therefore, alternative battery technologies based on other metal ions beyond Li ions have been extensively explored. [3] However, finding suitable electrode materials for these batteries to achieve comparative performance to the LIBs remains a challenging task since the charge-carrier metal ions possess much larger ionic radius and stronger interaction with the host materials owing to their multivalent nature. MXenesare seen as an exceptional candidate to reshape the future of energy with their viable surface chemistry, ultrathin 2D structure, and excellent electronic conductivity. The extensive research efforts bring about rapid expansion of the MXene families with enriched functionalities, which significantly boost performance of the existing energy-storage devices. In this review, the strategies that are developed to functionalize the MXene-based materials, including tailoring their microstructure by ions/molecules/polymers-initiated interaction or self-assembly, surface/interface engineering with dopants or functional groups, constructing heterostructures from MXenes with various materials, and transforming them into a series of derivatives inheriting the merits of the MXene precursors are highlighted. Their applications in emerging battery technologies are demonstrated and discussed. With delicate functionalization and structural engineering, MXene-based electrode materials exhibit improved specific capacity and rate capability, and their presence further suppresses and even eliminates dendrite formation on the metal anodes, which lengthens the lifespan of the rechargeable batteries. Meanwhile, MXenes serve as additives for electrolytes, separators, and current collectors. Finally, some future directions worth of exploration to address the remaining challenging issues of MXene-based materials and achieve the nextgeneration high-power and low-cost rechargeable batteries are proposed.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.202204988.
