$Ag-Si_3N_4$ nanostrutured composite has been investigated. The results show that it exhibits some novel properties such as strong piezpelectricity and high dielectricity. It can be constituted a battery using graphite and aluminum as the positive and the negative electrodes, respectively. The origins of these properties have been discussed.
