| Zusammenfassung: | The utility model provides a battery cell and current collector assembly and battery, the battery cell and current collector assembly includes battery cell, anode current collector and cathode current collector, the battery cell has anode ear and cathode ear, the anode ear and cathode ear both have straight section structure, and the anode ear and cathode ear have straight section structure. The anode current collector and the anode lug are brazed and fixed through a first brazing layer, so that electric contact is formed; and the cathode current collector and the cathode lug are brazed and fixed through the second brazing layer, so that electric contact is formed. On the basis that the tabs are kept in a straight section structure, fixing and electric contact are carried out through the brazing layer, and stable connection and sufficient electric contact between the tabs and the current collector are guaranteed. And the contact area with the current collector is not required to be increased by kneading and b |
