ELECTRODE ASSEMBLY AND SECONDARY BATTERY COMPRISING THE SAME

An electrode assembly according to the present invention comprises a positive electrode sheet comprising a positive electrode active material portion that is an area on which a positive electrode active material is stacked on a positive electrode collector and a positive electrode non-coating portion that is an area on which the positive electrode active material is not stacked, a positive electrode tab disposed on the positive electrode non-coating portion, a negative electrode sheet comprising a negative electrode active material portion that is an area on which a negative electrode active material is stacked on a negative electrode collector and a negative electrode non-coating portion that is an area on which the negative electrode active material is not stacked; a negative electrode tab disposed on the negative electrode non-coating portion, and a separator configured to insulate the positive electrode sheet and the negative electrode sheet from each other, wherein the positive electrode non-coating portion comprises a first positive electrode non-coating portion and a second positive electrode non-coating portion, which are provided on two portions spaced apart from each other on the positive electrode sheet.
