Abstract: The present invention discloses a banana plant cell, comprising at least one banana plant, at least one first electrode, and at least one second electrode. The banana plant is live and comprises organic acids as an electrolyte. The first electrode and the second electrode are used as an anode and a cathode, respectively. These two electrodes are inserted on the banana plant and are connected to each other. The banana plant cell according to the present invention belongs to a long-acting banana plant herb cell, thereby capable of solving the low efficiency problem of the fruit battery for long-term usage.
