Tesla has essentially optimized the shell, making it thinner, and reducing its internal complexity. They do this by welding the <a href=\"https:\/\/www.notateslaapp.com\/news\/2175\/teslas-dry-cathode-4680-battery-cells-will-mean-cheaper-better-evs\">tabless electrode<\/a> to the cell cap.<\/p>\n<p>That weight reduction is significant \u2013 at the battery pack level, the Cybertruck has 1,344 cells \u2013 which means that it reduces 28.2kg or 62.1lb of the overall pack weight. But rather than leaving that space empty, Tesla has instead filled that weight with more battery material. Calculated, that\u2019s about a 10% increase in overall pack energy density.<\/p>\n<p>The Limiting Factor intends to release another video looking at the energy density of the Cybercell and the detailed specs of the 4,680 cell. We\u2019ll be on the lookout for both of those videos in the coming weeks as they could reveal additional information on Tesla\u2019s 4,680 Gen 2 cells.
