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 Developing high-performance metal-free electrocatalysts for acidic oxygen evolution reaction (AOER) is highly desirable but remains great challenge. Here we report a rationally substituting sp-C strategy for the synthesis of methyl- and hydrogen-substituted graphdiyne (MGDY, HGDY) nanowires arrays as 3D porous flexible metal-free electrodes for AOER. Methyl group in MGDY with stronger electron-pushing effect makes electrons around the acetylenic carbon atoms more delocalized, resulting in more uneven distributed surface charge, and higher intrinsic catalytic activities for AOER than HGDY, with the smaller overpotential of 406 mV at 10 mA cm−2 than HGDY and previously reported metal-free electrocatalysts. Our results reveal that the modulation of the electronic structure of GDY by selectively substituting sp-C allows for facilitating charge transfer kinetics, improving adsorption of reaction intermediate, and thereby accelerating the sluggish kinetics of AOER. This work provides us an ideal opportunity for studying the exact HER/OER mechanisms of metal-free carbon materials.
