    So vastly bigger...how is that going to work with any output and input rates? Experts were already sceptical 2170's would be able to charge as quickly as 18650's (kWh for kWh) due to reduced (cooling) surface area.
    If true...a total departure from its chemistry heritage?

    I applaud anything that bring a higher practical Wh/kg. But Tesla needs 200kW or so from a 50kWh car to make its promised 0-60 dash possible. Even heavier and sooner dropoff?
    4416 would be a huge secret to keep for so long. 44mm cell would fit in 2 layers in the pack at most, one overlapping 2 cells in the lower layer.

    That's over 6" tall.

    Not likely with current pack designs. Of course they could orient them horizontally, but I have my doubts given that they've shown 2170's in conjunction with the Model 3 events.
