Abstract
Official abstract text for this publication.
Disclosed is a secondary battery. The secondary battery includes an electrode assembly having a plurality of unit electrode bodies, each electrode body including a positive electrode plate having a plurality of positive electrode uneven grooves into which a positive electrode active material is inserted, a negative electrode plate having a plurality of negative electrode uneven grooves located to face the positive electrode uneven grooves so that a negative electrode active material is inserted therein, and a unit separator interposed between the positive electrode plate and the negative electrode plate; and a case having an accommodation portion in which the electrode assembly and an electrolyte are accommodated, wherein the positive electrode plate and the negative electrode plate are symmetrical to each other on the basis of the unit separator.
First claim

1 . A secondary battery, comprising: an electrode assembly having a plurality of unit electrode bodies, each electrode body including a positive electrode plate having a plurality of positive electrode uneven grooves into which a positive electrode active material is inserted, a negative electrode plate having a plurality of negative electrode uneven grooves located to face the positive electrode uneven grooves so that a negative electrode active material is inserted therein, and a unit separator interposed between the positive electrode plate and the negative electrode plate; and a case having an accommodation portion in which the electrode assembly and an electrolyte are accommodated, wherein the positive electrode plate and the negative electrode plate are symmetrical to each other on the basis of the unit separator. 2 . The secondary battery according to claim 1 , wherein the plurality of unit electrode bodies are located to be stacked in one direction. 3 . The secondary battery according to claim 1 , wherein adjacent positive electrode uneven grooves or negative electrode uneven grooves of adjacent unit electrode bodies are engaged with the negative electrode plate or the positive electrode plate by fitting. 4 . The secondary battery according to claim 1 , wherein the secondary battery further comprises separators respectively interposed between the plurality of unit electrode bodies. 5 . The secondary battery according to claim 4 , wherein the separator is shaped to correspond to the positive electrode plate or the negative electrode plate adjacent thereto.
