Abstract |

内容記述 |
In this study, MgO was incorporated into the extensively studied solid electrolyte material, lithium borohydride (LiBH4), toenhance its poor ionic conductivity at ambient temperature. The addition of MgO was proved to significantly improve its ionicconductivity by approximately four orders of magnitude at 30°C compared to the low-temperature phase (less than 115°C) ofpristine LiBH4. Based on this electrolyte, all-solid-state batteries employing LiCoO2 as the cathode and MgO-modified LiBH4 asthe electrolyte were successfully fabricated and operated in the low-temperature range. Moreover, the initial charging processexhibited anomalous electrochemical behavior, delivering a remarkably high specific capacity of 285.2 mAh/g with an unconven-tional charge plateau at 1.6 V, which deviates substantially from the typical electrochemical characteristics of LiCoO2. To under-stand the charging mechanism from thermochemical and electrochemical views, a series of mechanistic characterizations wasperformed on the battery. Thermogravimetric analysis revealed a small amount of hydrogen evolution (≤ 0.2 wt%) at phase tran-sition temperatures, while solid-state NMR spectroscopy confirmed the formation of B O bonds, providing evidence for redoxreactions involving LiBH4. However, comparative electrochemical experiments and X-ray diffraction (XRD) analysis excludedthe influence of the thermal decomposition of LiBH4 during the charging process. The charging mechanism that controlled theelectrochemical behavior of this system was clarified in a detailed discussion. |
