Upon further reflection I realized that we need to define the metrics used
to measure lithium cells. The three most common methods are capacity (energy
density), power(continuous output in amps) and internal resistance. They
are all related. Capacity and continuous output rating are inversely proportional
and governed by the internal resistance which is related to the cathode
size. This means that the less internal resistance the greater the continuous
output can be. This is usually attained by a larger cathode which in turn
reduces the volume of anodic material and therefore the capacity of the
battery. All other parameters aside. The 4680 can be made with a physically
larger cathode without affecting energy density which lowers internal resistance
and therefore allows higher continuous output. This is important to a point
as continuous output must match or exceed the output of the motors and accessory
electronics. In summary the 4680 design offers a free boost in continuous
output at the same energy density over 2170s.
