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.

Abstract Perovskite-type solid-state electrolytes, Li0.35La0.55TiO3-xwt% LiF (LLTO-Fx, x = 0, 2, 4 and 6), were successfully synthesized through solid-state reaction method. The effects of LiF addition amount on LLTO crystal structure, morphologies and ionic conductivity have been investigated. All samples formed perovskite structure and the grain sizes were gradually increased with the increase of LiF content. Moreover, owing to the highest relative density (95.4%), LLTO-F2 electrolyte exhibited a highest total conductivity of 1.02×10-4 S/cm with a relative low activation energy of 0.26 eV, which is suitable for use in solid-state batteries. The cell Li/LLTO-F2/V2O5 exhibited a specific capacity about 270 mAh/g in the first few cycles and maintained 156 mAh/g after 100 cycles, demonstrating good cycling properties. Moreover, cells assembled with different cathodes, such as LiFePO4 and LiCoO2, also displayed excellent electrochemical performances. The results suggest that sintering additive (LiF) is very effective step towards ultimately achieve a safe solid-state lithium battery system.

One Step

We propose a technology for preparations of novel Si-NPs/carbon(Si/C) composites on the basis of thermal shock of the carbon materials such as natural and artificial graphites. We developed a facile, one-step carbothermal shock method for transformations from micro-Si to Si-NPs less than 150 nm size and well dispersed on carbon matrix (Figure 1.). The particle size distribution of the Si-NPs was narrow and the dispersion was uniform. The Si/C composite anode exhibited a high specific capacity (>1,000 mAh/g) and predominant fast charging behavior.
