Patent ID: 7554172

Claim:
An electrode plate for an electricity storage and discharge device, comprising: a plurality of I/O convergence terminals evenly distributed along a periphery of the electrode plate; and a plurality of conductive structures, each conductive structure for one of the I/O convergence terminals; wherein each conductive structure is of a radial pattern that centers on the one of the I/O convergence terminals, and radiates towards the interior of the electrode plate; the periphery of the electrode plate comprises a conductive frame that includes a first side, a second side that is opposite to the first side, a third side, and a fourth side that is opposite to the third side; a first one of the I/O convergence terminals is disposed on the first side; a second one of the I/O convergence terminals is disposed on the second side, diagonal to the first one of the I/O convergence terminals; a third one of the I/O convergence terminals is disposed on the third side; and a fourth one of the I/O convergence terminals is disposed on the fourth side, diagonal to the third one of the I/O convergence terminals.
