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%.

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.

In this study, we incorporated fast lithium ion conducting complex hydrides containing cluster anions, namely icosahedral dodecahydro-closo-dodecaborate anions, [B 12 H 12 ] 2− , into a bulk-type all-solid-state battery. Li 2 B 12 H 12 , TiS 2 and Li were used as an electrolyte, a positive electrode active material and a negative electrolyte, respectively, for a battery assembly to investigate its battery performance. Bulk-type battery contains high quantity of electrode active materials in the electrode layer, and thereby the enhanced energy-storage density is expected. In addition, non ammable solid-state electrolyte would ensure the safety, which is currently problematic for the conventional lithium rechargeable battery that uses organic liquid electrolyte. Li 2 B 12 H 12 has a high lithium ionic conductivity of log(σ/S cm −1 ) = −2.6 at 393 K. It exhibits a relatively higher conductivity of log(σ/S cm −1 ) = −3.5 at reduced temperatures such as 333 K. These high lithium ionic conductivity allows for the repeated operation of the bulk-type all-solid-state TiS 2 /Li battery for at least 10 cycles at not only 393 K but also 333 K with the discharge capacities higher than 190 mAh g −1 . Li 2 B 12 H 12 exhibits higher oxidative stability. Thus, our battery realized high coulombic ef ciencies of over 92% during the battery operation. This information will be bene cial for the further development of novel complex hydride-based electrolyte to have high-performance bulk-type all-solid-state batteries.
