The Verge article has a typo. It is not 4860, but 4680. So the actual volume is more than 5x of 2170. I guess the energy density is assume to be of equal proportion, since they are showcasing form factor improvement only in this slide. Power output increase is coming from efficient energy transfer due to tabless structure.

Incorrect writeup by Slashdot.

It is not 5x energy density. It is 5x more energy per battery. This is mainly because of higher volume of 4680 cells (132 cm3) vs 2170 cells (24.25 cm3). Power output is increasing by 6x because of tabless structure (better throughput for charging and discharging). I assume range increase is due to weight reduction achieved by structural efficiencies, which reduce overall weight. These improvements assume no difference in chemistry between 4680 and 2170.

Mr.Khosla is a prominent figure in the valley VC circuit. Anything he says should be taken in that light. He is either funding startups in the custom music business, or he is inviting such proposals for funding.

Do you have an idea in customized music? This would be the right time to get that pitch deck ready.
