“…As a result, repeated operation of the battery was successfully demonstrated. 9,10) On the other hand, considering the high reducing ability of the complex hydride electrolyte, our research group has proposed a battery design principles that uses positive electrodes with a lower voltage and high capacity electrodes including TiS 2 7,11) and elemental sulfur, 12,13) combined with a lithium negative electrode. Repeated operation of the batteries based on this design concept has also been successfully demonstrated.…”

We have operated a 4V-class bulk-type, all-solid-state LiCoO 2 /Li battery at room temperature. The battery consisted of a Li 4 (BH 4 ) 3 I complex hydride electrolyte as the electrolyte layer, and a 80Li 2 S 20P 2 S 5 sul de glass as an electrolyte in the positive electrode layer. The assembled battery exhibited a 92 mAh g −1 initial discharge capacity at 298 K and 0.1 C. The discharge capacity for the 20 th cycle remained as high as 83 mAh g −1 , corresponding to a capacity retention ratio of nearly 90%.

“…It has also been demonstrated that LiBH 4 can be utilized as a solid-state electrolyte in a Li/LiBH 4 /LiCoO 2 configuration [23]. This work utilized a PLD thin film of LiCoO 2 that was coated with a Li 3 PO 4 protecting layer to mitigate a chemical reaction from occurring at the LiBH 4 /Li 1−x CoO 2 interface.…”

Abstract:In this study, we analyze and compare the physical and electrochemical properties of an all solid-state cell utilizing LiBH 4 as the electrolyte and aluminum as the active anode material. The system was characterized by galvanostatic lithiation/delithiation, cyclic voltammetry (CV), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). Constant current cycling demonstrated that the aluminum anode can be reversibly lithiated over multiple cycles utilizing a solid-state electrolyte. An initial capacity of 895 mAh/g was observed and is close to the theoretical capacity of aluminum. Cyclic voltammetry of the cell was consistent with the constant current cycling data and showed that the reversible lithiation/delithiation of aluminum occurs at 0.32 V and 0.38 V (vs. Li + /Li) respectively. XRD of the aluminum anode in the initial and lithiated state clearly showed the formation of a LiAl (1:1) alloy. SEM-EDS was utilized to examine the morphological changes that occur within the electrode during cycling. This work is the first example of reversible lithiation of aluminum in a solid-state cell and further emphasizes the robust nature of the LiBH 4 electrolyte. This demonstrates the possibility of utilizing other high capacity anode materials with a LiBH 4 based solid electrolyte in all-solid-state batteries.

The introduction of structural disorder and large volume fractions of different kinds of interfaces enables the manipulation of ion dynamics in solids. Variable-temperature solid-state NMR relaxometry is highly useful to study Li(+) jump processes. If carried out as a function of frequency, the resulting NMR relaxation rates also contain information on the dimensionality (1D, 2D, or 3D) of the diffusion process. Recently, NMR relaxometry has revealed the 2D nature of Li hopping in LiBH4 , and thus this hydride is an interesting ion conductor for further diffusion studies on the spatially confined motion of Li spins. Here, nanocrystalline LiBH4 and the two-phase analogue LiBH4 :Al2 O3 , which are prepared by ball milling, serve as interesting model systems to track the changes in NMR relaxation rates with respect to coarse-grained, thermodynamically stable LiBH4 . This reveals that interface (nano)engineering influences the hexagonal-to-orthorhombic phase transition and thus alters the ion-transport properties of Li in one- and two-phase LiBH4 towards higher diffusivities at lower temperatures.
