The invention relates to an anti-corrosion type energy-storage ionic earthing array, which is characterized in that: a stainless steel ball conductor is provided with an ionic stick body and a water collecting bottle; the water collecting bottle is connected with the stainless steel ball conductor; the ball conductor contains ionic liquid; a floating ball is connected with a liquid level measuring rod which is arranged inside the ionic stick body through an end enclosure, a drain cap and a lower guide vane; the lower guide vane is fastened on the ionic stick body; and the end closure and the drain cap are fastened onto the ionic stick body by hollow fastening bolts. The anti-corrosion type energy-storage ionic earthing array has increased contact area with soil and reduced grounding resistance due to the ironic liquid filled in the stainless steel ball conductor, realizes the liquid level measurement of the ionic liquid in a ball body due to the arranged liquid level measuring device, can collect water molecule in the soil to the ball body with the additional water collecting bottle, can instantaneously store energy and absorb lightning pulse current to manyfold reduce lighting surge electromagnetic pulse, meets lightning protection requirements and realizes the functions of corrosion resistance, slow stored-energy release and low grounding resistance of the grounding electrode.
