在V3TiNi0.56储氢电池合金中添加0.204%纳米铜颗粒和0.102%稀土镓,并进行该汽车用新型钒基储氢电池合金的显微组织、物相组成及电池的电化学性能测试。结果表明,该新型储氢电池合金由V基固溶体相、TiNi相组成,具有明显的氧化峰和还原峰;V3TiNi0.56钒基储氢电池和新型钒基储氢电池,在充放电循环6次后的放电容量分别衰减了98.67%和9.62%,说明新型钒基储氢电池循环稳定性得到显著提高。
In the V3TiNi0.56 hydrogen storage battery alloy, 0.204% nano-copper particles and 0.102% rare earth gallium were added, and the microstructure, phase composition and electrochemical performance of the new vanadium-based hydrogen storage battery alloy were tested. The results show that the new hydrogen storage battery alloy consists of V-based solid solution phase and TiNi phase, and has obvious oxidation peak and reduction peak. The V3TiNi0.56 vanadium-based hydrogen storage battery and the new vanadium-based hydrogen storage battery are charged and discharged 6 times After the discharge capacity decay 98.67% and 9.62%, indicating that the new vanadium-based hydrogen storage battery cycle stability has been significantly improved.
