Abstract
Provided herein are battery packs for electric vehicles. A battery pack can include a housing having cavities. The battery pack can include electrode structures having a first tab terminal and a second tab terminal. A cover can be disposed over the housing. The cover can include first junction connectors extending between a first surface of the cover and a second surface of the cover. The first tab terminal of each electrode structure can be welded to respective first junction connectors.
