In Situ Formed Li–B–H Complex with High Li-Ion Conductivity as a Potential Solid Electrolyte for Li Batteries

Abstract

Li−B−H complexes facilely prepared via partial dehydrogenation of LiBH 4 are presented in this study as solid electrolytes for Li batteries. An exceptionally high Li-ion conductivity is found for the Li−B−H complex with 7.5 wt % H 2 desorption under 3 bar H 2 pressure, which reaches 2.7 × 10 −4 S cm −1 at 35 °C, more than 4 orders higher than that of LiBH 4 . In-depth characterizations show that LiH and [Li 2 B 12 H 11+1/n ] n are in situ formed in the LiBH 4 matrix and the interface layer between [Li 2 B 12 H 11+1/n ] n and LiBH 4 is believed to be responsible for the high Li-ion conductivity. Moreover, this Li−B−H complex also exhibits excellent electrochemical stability, which enables the stable cycling of all-solid-state batteries at room temperature.

Adsorption‐Catalysis Design in the Lithium‐Sulfur Battery

“…The result indicates that both catalysis and adsorption ability work together in the V 2 O 3 cathode. [41] In recent investigations, MnO 2 is a vital material to serve as an efficient catalyst to enhance the conversion kinetics for Li-S battery, strenuous effort has been done. Jin et al proposed a hierarchical composite formed by some conducting matrixes (Ni foam, graphene, CNTs) with MnO 2 nanoflakes (NGCM) as the layer for Li-S battery.…”

Solid‐State Prelithiation Enables High‐Performance Li‐Al‐H Anode for Solid‐State Batteries

“…We also believe that the overall electrochemical performance of the solid‐state full cell can be further improved by i) using highly Li‐ion conductive Li‐B‐H based electrolyte to enable the stable cycling at room temperature; [ 35–41 ] ii) modifications on the cathode/electrolyte interface to avoid the formation of thick cathode electrolyte interphase film. [ 42–45 ] The above results prove that the SSPP Li‐Al‐H anode is very promising for future practical applications.…”
