AgO ordered array materials were synthesized by electrochemical oxidization of Ag naoparticles in sodium hydroxide solution. As the characterizations of properties revealed

the prepared AgO material has unique straight-through hollow structure

bringing a positive effect on the dispersion of electrolyte inside materials

which would result in better electrochemical properties of corresponding batteries. Thus prepared AgO material could be used as an electrode directly without any binders. The electrode offered a discharge capacity of 422.6 mA·h·g-1 at 3 C rate and utilization ratio of electrode material could reach 97.8% as a cathode of Al/AgO battery (stopping potential is 0.5 V and reference electrode is Ag/Ag+ electrode). There was still a capacity of 387.8 mA·h·g-1 at 7 C rate with utilization ratio 89.7%. Meanwhile

the cycling performance was also improved and a specific capacity of 405.2 mA·h·g-1 could still be offered at the 10th cycle. The work provides a facile and eco-friendly method and the prepared AgO materials would have unique advantages in practical applications.
