The present invention provides an electricity storing/discharging device with single-layer folding covering and packaging single input/output electric conductive interface having electrode plate pair with multiple-sided electric conductive terminals, which is applied in a specified single-layer folding covering and packaging structure having electrode plate pair with multiple-sided electric conductive terminals, so the electrode plate pair with multiple-sided electric conductive terminals after being covered and packaged is able to be structured as a single input/output electric conductive interface through single input/output electric conductive terminal having positive and negative polarity for transferring electric energy to the exterior.
