Which makes it heavier no?

• TheAdamAndChe 6y ago
  No. A rectangular block of a typical battery has a much lower surface area-to-mass ratio than a tube, even if their weights are the same. It's why cooling fins on a CPU are long and skinny. Such length and skinniness makes heat dissipation much easier.

    But if the energy density is higher wouldn't you need more material to cool down the area?
