In this study mechanical alloying process with subsequent annealing at 750°C for 0.5 h were used to produce Ti_2Ni-based nanocrystalline alloys and composite. To improve electrochemical properties, Ti-Ni-based alloy was chemically modified by 5 wt% of silver powder. X-ray diffraction analyses showed formation of nanocrystalline Ti_2Ni main phase. Electrochemical studies revealed a positive effect of chemical modification by silver on Ti_2Ni alloy. All synthesized materials were used as negative electrodes for Ni-MH_x batteries. The highest discharge capacity equaled 303 mAh/g, at 40 mA/g discharge current. All electrochemical measurements were done in 6 M KOH solution.
