It is more preferable.

The soil layer is the soil in which the plant is planted.

Since the soil layer contains moisture for plant cultivation, protons generated at the anode electrode may move to the cathode electrode, and water generated at the cathode electrode may move to the anode electrode through the soil layer.

The soil layer may be added with a weak acid electrolyte. In such a case, the growth of the plant is promoted, and the protons contained in the soil layer are increased, so that a smoother generation of electric current is possible.

In addition, the cathode electrode according to the present invention may be an electrode manufactured by including a carbon material. In the case of an electrode including a carbon material, it is environmentally friendly due to less corrosion and abrasion than an electrode made of a metal material such as iron, zinc, or copper in the soil layer containing moisture, and thus no additional product is generated. In addition, the degree of oxidation is less than that of metal, it has excellent durability, and the replacement cycle is very long.

Preferably, the electrode including the carbon material may be an anion of the surface functional group. In such a case, the potential difference with the anode electrode is increased, so that the amount of current generated is larger, and even if the anode electrode is made of an electrode containing a carbon material, a potential difference is formed with the anode electrode, thereby allowing current generation.

The method of anionizing the surface functional group is not particularly limited and any method known in the art may be used without limitation, and for example, an acid treatment, a high temperature treatment, an iodine treatment, or the like may be used.

The distance may be, for example, 0.5 to 5 cm, but is not limited thereto. If the separation distance is less than 0.5cm, it is difficult to maintain the gap between the electrodes may cause a short circuit. When the separation distance is greater than 5 cm, the material exchange of the reaction scheme between the anode electrode and the cathode electrode is difficult, and current generation efficiency may be reduced.

Preferably, in the plant soil battery of the present invention, the anode electrode and the cathode electrode may be in contact with each other with the separator interposed therebetween. In such a case, the separation distance between the anode electrode and the cathode electrode can be minimized while minimizing the separation distance between the anode electrode and the cathode electrode, and the current generation efficiency is excellent.
