An electrode plate multi-end sides to single end side current collector of an electricity storage/discharge device is an improved multi-end sides to single end side input/output current collecting terminal structure being applied to the electrode plate of an electricity storage/discharge device for applications in electricity storage/discharge devices such as primary batteries, secondary chargeable/dischargeable batteries, capacitors, or super-capacitors, or fuel cell power supply device having electrode plates, wherein two or more than two end sides of each electrode plate of above said device are made with one or more than one current collecting terminal structure thereby allowing the electrode plate via multiple current collecting terminals on multi-sides to collect currents in multi-circuits, wherein the auxiliary electric conductor is additionally installed between the positive or negative electrode plate installed on end-side of individual electrode cell and the electrode cell casing, and the insulator is installed between the electrode plate and the auxiliary electric conductor thereby allowing current collecting terminals at different end-sides of the electrode plates in the same polarity to be connected via the auxiliary electric conductors to collect the currents of current collecting terminals at multiple end sides to the current collecting terminal at single end side to facilitate collecting input/output currents to the outside, wherein the number of external input/output current collecting terminals on the single end side of electrode plate can be one more than one.
An electricity storage/discharge device, wherein the lattice shape space for installing active matter (120) with electricity storage/discharge function on all or partial electrode plates and the electric conducting structure at outside frame of electrode plates have larger effective electric conducting area at the location nearer to the input/output current collecting terminal, thereby reducing the impedance and favoring the uniformed transmission of current density;
- The electric conducting structure at outside frame of said all or partial electrode plates at neighborhood nearer to the input/output current collecting terminals has larger effective electric conducting cross-sectional area, wherein the structural characteristic includes outwardly slantingly gradually widened, or gradually thicker, or both gradually widen and thicker, thereby forming the structure of current collecting conductor to have more gradually increased effective current transmission area at locations nearer to the input/output current terminals;
- Aforesaid structure for enhancing the electrode plate current collecting function of current collecting terminals further includes the electrode plates being applied in conventional electricity storage device comprising electricity storage/discharge device of conventional primary battery, secondary chargeable/dischargeable battery, capacitors, or super-capacitors, or fuel cell power supply device having electrode plates.
