<p>The present invention relates to a negative lug and a battery. The negative lug comprises a body, and the body is provided with multiple bumps. The body of the negative lug of present invention is provided with bumps, so that during spot welding between the negative lug and the bottom of the battery, the contact resistance is increased, so as to enhance the welding strength, make the negative lug securely welded and avoid problems of lack of fusion or insecure spot welding, thereby ensuring the normal use of a battery and increasing the pass rate of the product.</p> |
