The 2680 batteries will
The 2680 batteries will probably be about 15% more energy dense per kg than the current Tesla battery. The max power output will be about 20% more, which is important for bigger vehicles like the tesla truck. Most of the advantage will come from them being bigger and so cheaper to manufacture per Wh. Also there will be only about 1/5 the number of cells in a battery pack making them easier to make.
