“…[179] Moreover, inorganic nanofiller TiO 2 addition further decreased the phase transition temperature and enhanced the conductivity. [182,183] Karan prepared (1-x) PEO:xZn (CH 3 COO) 2 SPEs with the conductivity of 1.22 × 10 −7 S cm −1 and the Zn ion migration number of 0.17 by hot press casting technique. [184] In the same situation, the conductivity of the SPEs obtained by replacing the zinc salt with Zn(OTf) 2 had increased by ten times (1.09 × 10 −6 S cm −1 ), indicating that the selection of the appropriate salts was also crucial to the electrochemical performance of the electrolytes.…”

Designing high performance electrolyte is an efficient strategy to circumvent these problems. As one of the most important components, electrolytes provide the basic operating environment to guarantee the transmission of the Zn 2+ between the two electrodes during the charge-discharge processes, affect the Zn 2+ /Zn plating/ stripping on the anode and deciding the electrochemically stable potential windows. [12] Since the utilization of alkaline electrolytes in batteries in earlier studies, Zn|KOH|MnO 2 batteries became a hot topic. [13] However, the using of an alkaline electrolyte always leads to the growth of Zn dendrites and the corrosion of the anode, resulting in rapid capacity fading. [14][15][16] Until 1986, the replacement of corrosive alkaline electrolyte systems by neutral aqueous electrolytes greatly improved the performance and safety of ZIBs. [17] Although the aqueous electrolytes alleviated the corrosion of the Zn electrode in some extent, the problems related to the growth of dendrites and the dissolution of the cathode, especially the limited electrochemical stability window (≈1.23 V) still are the challenge in the application of ZIBs. [18][19][20] The aqueous electrolytes of ZIBs often suffer from the water splitting process, including hydrogen evolution reaction and oxygen evolution reaction. [21][22][23] Therefore, in order to overcome the problems mentioned above, "beyond aqueous" electrolytes for ZIBs have attracted extensive attention in recent years. [24][25][26] At present, the "beyond aqueous" electrolytes for ZIBs have been reported mainly include liquid organic electrolytes and solid electrolytes. Zn anode in the organic electrolytes have high thermodynamic stability, avoiding the appearance of passivation products inevitably generated in traditional aqueous solution, i.e., ZnO and Zn(OH) 4 −2. [27] Solid-state electrolytes have sufficient mechanical strength to inhibit the growth of dendrites. [28] Moreover, the "beyond aqueous" electrolytes without water fundamentally avoid the decomposition of water and the formation of side products related to water. Compared with aqueous electrolytes, the "beyond aqueous" electrolytes exhibit a wide electrochemical stability window (Figure 1) and excellent thermodynamic stability of Zn anode leading to Zn plating/ stripping high reversibility with higher Coulombic efficiencies (CEs). [29] Although significant advances have been made in improving the electrochemical performance of the "beyond aqueous" electrolytes for ZIBs, several severe issues still exist, which largely prevent the development of "beyond aqueous" ZIBs. [30][31][32][33][34][35] The main issues of "beyond aqueous" electrolytes With the growing demands for large-scale energy storage, Zn-ion batteries (ZIBs) with distinct advantages, including resource abundance, low-cost, high-safety, and acceptable energy density, are considered as potential substitutes for Li-ion batteries. Although numerous efforts are devoted to design and develop high performance cathodes and aqueous electrolyt...

Exploring ionic liquid-laden metal-organic framework composite materials as hybrid electrolytes in metal (ion) batteries

et al. 2022

This review focuses on the combination of metal-organic frameworks (MOFs) and ionic liquids (ILs) to obtain composite materials to be used as solid electrolytes in metal-ion battery applications. Benefiting from the controllable chemical composition, tunable pore structure and surface functionality, MOFs offer great opportunities for synthesizing high-performance electrolytes. Moreover, the encapsulation of ILs into porous materials can provide environmentally benign solid-state electrolytes for electrochemical devices. Due to the versatility of MOF-based materials, in this review we also explore their use as anodes and cathodes in Li- and Na-ion batteries. Finally, solid IL@MOF electrolytes and their implementation into Li and Na batteries have been analyzed, as well as the design and advanced manufacturing of solid IL@MOF electrolytes embedded on polymeric matrices.

“…Despite the great progress in designing CPEs, their interfacial resistance and unstable electrode–CPE interfaces provide more serious constraints, leading to deterioration of the high-energy density and long-term stability of PSSBs. 30–40 Their main interfacial problems include the following four aspects: (1) their high interfacial resistance across the interface is caused by the poor interfacial contact of the cathode–CPE and anode–CPE interfaces. It is challenging to construct an intimate contact between electrodes and CPEs, as there is no liquid fluidity.…”
