“…[26] However, the demanding preparation process (high-temperature, chemical pretreatment) and moisture-proof storage condition would compromise the potential scalability of the strategy. [27][28][29][30] To better afford the fundamental insights for the practical Li metal battery (LMB) designs (for instance the cathode/anode pairing, formation protocols, irreversible capacity origin of the cell model), additionally, the in-depth theoretical elucidation and real-time phase tracking of the alloy transition were urgently required, yet the associating studies of which remained scarce thus far. Surface coating is a common strategy to modify the physicochemical properties of the separators such as ionic conductivity, lithium transference number, porosity, and electrolyte wettability.…”

solutions, explorative studies of the electro-redox couples, with the concurrent high retrievable capacity, enlarged nominal voltage gap, and rapid reaction kinetics, hold the key to promote the energy-dense battery construction at the extreme power output. [1] For the lithium ion batteries, the energy densities of traditional formats (LiCoO 2 /LiFePO 4 cathodes and graphite anodes) have approached their theoretical limits. [2] Alternatively, the unit cell prototyping of the high-capacity Li metal anode with the nickel-rich cathode can achieve the enhanced level of energy densities at the device level. [3,4] When soaking this electrode couples in the conventional carbonate-based electrolytes, however, the Fermi-energy incompatibility at the multiscale interface would cause the uncontrollable dendrite growth on the metallic foil and cathode structure collapse upon the high-voltage cycling. [5] Therefore, the reliable operation of the energy-dense battery necessitates the harmony balance of the enlarged voltage gap and the interfacial stability at multiple scales, yet still remains challenging.As the most attractive cathode type of the practical relevance, nickel-rich (Ni content >0.8) layered oxides exhibit the merits of the large specific capacity (>200 mAh g −1 ), environmental benignity and relative lower cost as compared to the LiCoO 2 cathode. Despite of the dominant nickel occupancy in the layered oxides for elevating the Li storage sites, the increased nickel ratio adversely deteriorates the cycle performance. The transition metal (TM) layer of the oxide structure at the highvoltage charged states would oxidize the carbonate solvents in the presence of moisture, leading to serious self-discharge rates upon the high-temperature storage. [6] Additionally, the hydrofluoric acid (HF) formed by the decomposition of the lithium hexafluorophosphate (LiPF 6 ) salt aggravates the TM ions (Co 2+ , Ni 2+ , and Mn 2+ ) dissolution and structural collapse of the layered cathode, meanwhile the TM species would deposit on the anode surface and degrade the solid electrolyte interface (SEI). [7] So far, a plethora of mitigation strategies were implemented to insulate the direct contact of the oxide particles with the electrolyte, for instance the exquisite coatings with The reliable operation of Li metal batteries suffers from cathode collapse due to high-voltage cycling, interfacial reactivity of the Li deposits, self-discharge at the elevated temperatures, as well as the power output deterioration in low-temperature scenarios. In contrast to the individual electrode optimization, herein, a hetero-layered separator with an asymmetric functional coating on polyethylene is proposed in response to the aforementioned issues: On the face-to-cathode side, the hybrid layer of the molecular sieve and sulfonated melamine formaldehyde can scavenge the hydrofluoric acid and moisture residues from the carbonate electrolyte, maintaining the cathode robustness in both the high-voltage cycling or high-temperature storage scenarios; while...

Solid‐state energy storage devices (SSESDs) are believed to significantly improve safety, long‐term electrochemical/thermal stability, and energy/power density as well as reduce packaging demands, showing the huge application potential in large‐scale energy storage. Nevertheless, some key issues like low ionic conductivities, poor interface contact, and dendrites growth limit the practical application of SSESDs. In recent years, MXenes for SSESDs have received reassuring advances on account of unique parameters. Nevertheless, overall reviews about the subject are seldom. In this review, current advances of MXenes and their derivatives in solid‐state Li–metal, Li‐ion, Li–I/S, Na‐ion, Zn–air, Zn–metal batteries, and supercapacitors in cathode/anode optimization, interface medication, and electrolyte fillers, etc., are comprehensively reviewed. First of all, essential principles of MXenes are shown, such as precursors, etching/delamination strategies, as well as superior properties for energy storage systems. Meanwhile, the classification and evaluation parameters of solid‐state electrolytes are summarized. Subsequently, the application, modification mechanism, and design strategy of MXenes for boosting electrochemical behaviors of SSESDs are systematically reviewed and discussed. At last, perspectives and challenges about the future construction strategies of MXenes for SSESDs are recommended. This review shall assist scientists design and build advanced SSESDs with superior energy density along with safety.
