An electrode assembly includes: a positive electrode plate including a positive electrode collector having, on its first side, a positive electrode coating portion having a positive electrode active material thereon and a first positive electrode non-coating portion; a positive electrode tab on the first positive electrode non-coating portion; a negative electrode plate including a negative electrode collector having, on its first side facing the first side of the positive electrode collector, a negative electrode coating portion having a negative electrode active material thereon and a first negative electrode non-coating portion; and a separator between the positive and negative electrode plates. The first positive electrode non-coating portion is between ends of the positive electrode plate, and the first negative electrode non-coating portion overlaps the first positive electrode non-coating portion. |

1. An electrode assembly comprising:
a positive electrode plate comprising a positive electrode collector having a positive electrode coating portion and a first positive electrode non-coating portion at a first side thereof, the positive electrode coating portion having a positive electrode active material thereon, the first positive electrode non-coating portion being an exposed portion of the positive electrode collector; a positive electrode tab coupled to the first positive electrode non-coating portion; a negative electrode plate comprising a negative electrode collector having a negative electrode coating portion and a first negative electrode non-coating portion at a first side thereof, the negative electrode coating portion having a, negative electrode active material thereon and facing the first side of the positive electrode collector, the first, negative electrode non-coating portion being an exposed portion of the negative electrode collector; and a separator between the positive electrode plate and the negative electrode plate, wherein the first positive electrode non-coating portion is offset from ends of the positive electrode plate along a length direction of the positive electrode plate, and the first negative electrode non-coating portion overlaps the first positive electrode non-coating portion. |
