1. A sleeve comprising: two plug-in openings located at opposing ends of the sleeve for inserting a stranded conductor and having a tapered lead-in in a form of a transition at an outer end of the sleeve to initially receive insertion of the stranded conductor into the sleeve, which narrows in a form of a funnel, from an outer diameter to an inner diameter, to avoid any sharp edges that might compromise stability of the stranded conductor; wherein the sleeve is rotationally symmetrical;wherein the sleeve is made of brass, an alloy containing copper or zinc, or two layers of different materials;wherein the sleeve holds an end of the stranded conductor and the sleeve forms a contact that is welded to an aluminum substrate; andwherein the stranded conductor and the sleeve are compressed in more than one location along a length of the sleeve. 2. The sleeve according to claim 1, wherein the sleeve is closed at least locally a full 360° around a circumference of the stranded conductor. 3. The sleeve according to claim 1, wherein the tapered lead-in avoids radii of curvature of greater than 0 and less than 0.5 mm. 4. The sleeve according to claim 1, wherein an overall cross-section of the sleeve and conductor is at least 0.5 mm2. 5. A contacting device comprising: a substrate anda stranded conductor,wherein the stranded conductor includes a sleeve according to claim 1 that is mounted on the substrate, and the conductor is crimped to the sleeve. 6. The contacting device according to claim 5, wherein the sleeve is mounted on the substrate over an uncrimped part of the length. 7. The contacting device according to claim 5, wherein a metallic material of a core of the conductor and a metallic material of the substrate have an electrochemical potential difference of more than 0.3 V, and the sleeve is made of a metallic material, an electrochemical potential of which lies between that of the core of the conductor and that of the substrate, wherein the substrate is made of an aluminum material, the core of the conductor is made of a copper material and the sleeve is made of a brass material or a CuZn material. 8. A battery having a contacting device according to claim 5, wherein the substrate is made of an aluminum material. 9. A vehicle having a contacting device according to claim 5, wherein the vehicle includes a battery having the substrate that is made of an aluminum material. 10. A method for connecting a stranded electric conductor to a substrate comprising the steps of: a) inserting the stranded electric conductor into a sleeve according to claim 1,b) first crimping the sleeve to the conductor, thereby fastening the electric conductor in the sleeve, wherein the sleeve has a rotational symmetric form and crimping is done rotationally symmetrically, or leaves a part of the sleeve in a rotationally symmetric form, so that the sleeve can be placed on the carrier object independent of the direction of its longitudinal axis,c) placing the conductor with the sleeve on the substrate,d) connecting the sleeve which encompasses the conductor to the substrate by ultrasonic welding and/or by a second crimping. 11. The method according to claim 10, wherein the first crimping is carried out over only a part of a length, rather than over an entire length, and in that the connection between the sleeve and the substrate is established only in the uncrimped region of the sleeve. 12. The method according to claim 10, wherein in an uncrimped state, the sleeve has a rotationally symmetrical cross-section, and the sleeve remains rotationally symmetrically at least in sections even after crimping. 13. The sleeve according to claim 1, wherein the two layers of the sleeve comprise a first outer layer of electrically conductive material which is softer than brass, and a second inner layer made of brass; and wherein the first outer layer is welded to the substrate while the second inner layer remains intact. 14. The sleeve according to claim 13, wherein the first outer layer is made of copper. 15. The sleeve according to claim 1, wherein the two layers of different materials are hermetically sealed together so that no contact corrosion can result on contact surfaces between the two layers of different materials. 16. The sleeve according to claim 1, wherein the sleeve is mounted on the substrate by ultrasonic welding. 17. The sleeve according to claim 1, wherein the sleeve is closed at least locally a full 360° around a circumference of the stranded conductor, and the sleeve is free of seams. 18. The sleeve according to claim 1, wherein in an uncrimped state, the sleeve has a rotationally symmetrical cross-section, and the sleeve remains rotationally symmetrical at least in sections even after crimping. 19. A sleeve comprising: at least one plug-in opening for inserting a stranded conductor and having a tapered lead-in in a form of a transition at an outer end of the sleeve to initially receive insertion of the stranded conductor into the sleeve, which narrows in a form of a funnel, from an outer diameter to an inner diameter, to avoid any sharp edges that might compromise stability of the stranded conductor; wherein the sleeve is rotationally symmetrical;wherein the sleeve is made of brass, an alloy containing copper or zinc, or two layers of different materials;wherein the sleeve holds an end of the stranded conductor and the sleeve forms a contact that is welded to an aluminum substrate;wherein the sleeve is a hollow cylinder closed at least locally a full 360° around a circumference of the stranded conductor;wherein the sleeve is configured to be placed on the substrate, independent of its orientation relative to a longitudinal axis; andwherein the stranded conductor and the sleeve are compressed in more than one location along a length of the sleeve.
