“…LiBH 4 has been already reported to be able to plat/ strip lithium for a longer time and at higher current densities. 17,45 The contact resistance of the cell was calculated by multiplying the cell resistance (after having subtracted the SSE contribution), divided by a factor of 2 (since the two interfaces are considered equivalent), by the contact surface. It turns out to be about 565 Ω cm 2 , a much higher value than that reported by Kim et al 46 on carborane SSEs (<1 Ω cm 2 ).…”

LiBH 4 has been widely studied as a solid-state electrolyte in Li-ion batteries working at 120 °C due to the low ionic conductivity at room temperature. In this work, by mixing with MgO, the Li-ion conductivity of LiBH 4 has been improved. The optimum composition of the mixture is 53 v/v % of MgO, showing a Li-ion conductivity of 2.86 × 10 –4 S cm –1 at 20 °C. The formation of the composite does not affect the electrochemical stability window, which is similar to that of pure LiBH 4 (about 2.2 V vs Li + /Li). The mixture has been incorporated as the electrolyte in a TiS 2 /Li all-solid-state Li-ion battery. A test at room temperature showed that only five cycles already resulted in cell failure. On the other hand, it was possible to form a stable solid electrolyte interphase by applying several charge/discharge cycles at 60 °C. Afterward, the battery worked at room temperature for up to 30 cycles with a capacity retention of about 80%.

“…[1][2][3][4] Nevertheless, the safety issues, high cost, and the limited lithium resources impede from their continuous and widespread utilization and the subsequently development. [5][6][7] As a promising candidate to substitute the LIBs, ZIBs have unique merits including high safety, environmentally friendly, resource abundance, and convenient preparation, arising significant attention in recent years. [8][9][10][11] However, the growth of dendrites, hydrogen evolution reaction and side reactions severely hinder the further development of ZIBs.…”

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...

“…However, the development of LIBs still suffers from challenges that associated with safety, energy density and lifespan. To further address these bottlenecks, fabricating all-solid-state lithium batteries (ASSLBs) with solid electrolyte (SE) and lithium (Li) anode is considered to be a promising solution [3][4][5][6][7]. On the one hand, SE can offer good mechanical strength and non-flammability, rendering the safety of ASSLBs.…”
