Conduction Properties

Solid electrolytes with high Li-ion conductivity and electrochemical stability are very important for developing high-performance all-solid-state batteries. In this work, Li2(BH4)(NH2) is nanoconfined in the mesoporous silica molecule sieve (SBA-15) using a melting–infiltration approach. This electrolyte exhibits excellent Li-ion conduction properties, achieving a Li-ion conductivity of 5.0 × 10−3 S cm−1 at 55 °C, an electrochemical stability window of 0 to 3.2 V and a Li-ion transference number of 0.97. In addition, this electrolyte can enable the stable cycling of Li|Li2(BH4)(NH2)@SBA-15|TiS2 cells, which exhibit a reversible specific capacity of 150 mAh g−1 with a Coulombic efficiency of 96% after 55 cycles.

Effect Of The Composition

In our research, composite cathodes of strontium-doped lanthanum manganite (LSM) and yttria-stabilized zirconia (YSZ) were produced by using slurry casting and sintering procedures. The slurry was prepared using ball milling. The time of ball milling was studied in terms of particle size and homogeneity of the powder in the slurry. The effect of the composition of the slurry on the microstructure was studied to obtain cathodes with desired porosity. The sintering process was also optimized to compromise the porosity, grain size, and strength of the cathodes. The YSZ coating was implemented using electrophoretic deposition in liquid phase. Different charging methods of the YSZ powder in the suspension was used and their results were compared. The microstructures of cathodes and YSZ coatings were characterized using scanning electron microscope (SEM).
