Abstract: The practical application of LiBH 4 for solid-state hydrogen storage is hindered by its sluggish kinetics and high thermodynamic stability. To address these challenges, we constructed a multiphase catalytic system within LiBH 4 by incorporating nano-BaTiO 3 and carbon nanotubes (CNTs) through ball milling. The composite of LiBH 4 , 20 wt% BaTiO 3 and 20 wt% CNTs exhibits significantly enhanced dehydrogenation properties, with an initial temperature as low as 223 °C and a peak desorption temperature of 353 °C, releasing 8.2 wt% H 2 at 500 °C. The modified composite demonstrates markedly improved reversibility and kinetics, evidenced by a retained capacity of 4.1 wt% after the 6th cycle and a substantially decreased activation energy of 123 kJ mol−1. During the first dehydrogenation, LiBH 4 reacts in-situ with BaTiO 3 to form Li 3 BO 3 , BaB 6 , and TiO 2 phases. These products, in conjunction with CNTs, form a multifunctional catalytic framework. Among them, BaB 6 serves as the nucleation site, TiO 2 acts as the active catalyst, and Li 3 BO 3 facilitates ion transport, collectively enhancing the reaction kinetics and cycling stability of LiBH 4. Meanwhile, the CNTs provides dual functions of confinement and excellent thermal conductivity, which suppressing particle aggregation and enhancing thermal diffusion rate. Consequently, the composite exhibits a lower decomposing temperature, rapider kinetics, and enhances reversibility compared with the as-milled LiBH 4. This work provides an effective strategy of in-situ engineering a multiphase interface to attain high-performance solid-state hydrogen storage materials. • The composite of LiBH 4 , 20 wt% BaTiO 3 , and 20 wt% CNTs begins to decomposes at 223 °C, releasing 8.2 wt% H 2 at 500 °C. • LiBH 4 reacts in-situ with BaTiO 3 to yield Li 3 BO 3 /BaB 6 /TiO 2 multiphase catalyst. • CNTs simultaneously provide spatial confinement and increased thermal conductivity. • The synergistic effect of multiphase improves the hydrogen storage kinetics & cyclability of LiBH 4.
