Multi-layer betavoltaic battery using perovskite compound and manufacturing method thereof

Abstract

The present disclosure discloses a betavoltaic battery using a perovskite compound, comprising: internal electrodes including a plurality of internal anodes and a plurality of internal cathodes alternately arranged, wherein at least one of the internal anodes and the internal cathodes includes a radioisotope that emits beta rays; perovskite compound layers disposed between each of the internal anodes and the internal cathodes; an external anode connected to the plurality of internal anodes; an external cathode connected to the plurality of internal cathodes; and a radiation shielding layer surrounding an outer periphery of the battery, excluding at least a portion of the external anode and the external cathode. According to the present invention, since the perovskite compound layers and the internal electrodes can be alternately stacked up to hundreds of layers, it is possible to provide a betavoltaic battery with high energy density and maximized capacity relative to its volume.
