Provided herein are systems, apparatuses, and methods of providing electrical energy for electric vehicles. A battery pack can be disposed in an electric vehicle to power the electric vehicle. A battery cell can be arranged in the battery pack. The battery cell can have a housing. The housing can define a cavity within the housing. The battery cell can have an electrode structure arranged within the cavity. The electrode structure can include a first polarity electrode plate, a second polarity electrode plate, and at least one separator. First and second polarity tabs are coupled with the first and second polarity electrode plates, respectively. The tabs include a flat surface, an electrode interface surface and at least one intermediate surface that extends therebetween. The at least one intermediate surface forms an acute angle with the electrode interface surface.
