Patent ID: 8551660

Claim:
An electrode unit for a reserve power supply, comprising: at least one electrode plate ( 101 ) having at least one current collecting terminal ( 104 ) extending from each of at least two sides of the at least one electrode plate ( 101 ), said at least one electrode plate ( 101 ) having an active surface on which is coated an active substance ( 120 ); and at least one auxiliary conductor ( 100 ) having a conductivity higher than a conductivity of the at least one electrode plate ( 101 ), said at least one auxiliary conductor ( 100 ) having at least one current collecting terminal ( 105 ) extending from each of at least two sides of the at least one auxiliary conductor ( 100 ); and an insulator ( 103 ) sandwiched between and joined to the at least one electrode plate ( 101 ) and to the at least one auxiliary conductor ( 100 ) to form said electrode unit, wherein said at least one current collecting terminal ( 104 ) extending from each of at least two sides of the electrode plate ( 101 ) and said at least one current collecting terminal ( 105 ) extending from each of at least two sides of the auxiliary conductor ( 100 ) are electrically connected to form at least two common input/output terminals on opposite sides of the electrode unit.
