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
Opening claim text (preview).
The invention claimed is: 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, wherein each positive electrode plate comprises one or more spaces disposed between adjacent positive electrode uneven grooves and each negative electrode plate comprises one or more spaces disposed between adjacent negative electrode uneven grooves, and wherein adjacent positive and negative electrode plates are engaged with one another so that one or more of the positive electrode uneven grooves are fitted into one or more of the negative electrode spaces and one or more of the negative electrode uneven grooves are fitted into one or more of the positive electrode spaces. 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 the secondary battery further comprises separators respectively interposed between the plurality of unit electrode bodies. 4. The secondary battery according to claim 3 , wherein the separator is shaped to correspond to the positive electrode plate or the negative electrode plate adjacent thereto.
