    摘要： The present invention discloses a battery electrode plate and a forming method thereof and a battery having the same. The battery electrode plate comprises squared current collector with electrode material being coated on at least a portion of the current collector, the portion thereof has a first thickness region, a second thickness region which has a thickness smaller than that of the first thickness region, and a transition region tapering from the first thickness region toward the sec ond thickness region. The present invention further discloses a method of forming the electrode plate and a battery having the same. The current collector in the present invention may not break or drape or wrinkle in rolling, and as a result, the yield rate of the electrode plate may be improved and is benefit for large scale industrial production. And the battery thus formed may have improved safety performance.
