And that would normally be true of a solid narrow or thin block of metal however the battery is a series of very thin sheets of flexible metal (could be a dozen or more depending on the voltage required), separated by a very low thermally conductive Lithium paste (the electrolyte), then folded into a wallet style configuration similar to a billfold, and with the anode at the middle of the entire folded package.
And with each layer of the paste separating the layers of conducive material you have a greater resistance to thermal conductivity.
It's not too much different in architecture than a standard round or barrel shaped battery except if you were to take that battery and basically squash it flat.
Still my point is not that the battery will or won't get hotter as a whole, but that the anode will get much hotter but for shorter bursts of time. The net result of total heat generated in terms of BTUs may be similar but the intensity of that heat at the surface of the anode (where the actual damage occurs), will be higher for periods of time as a result of the higher voltage and current applied in those short durations. It's that higher anode temperature that results in battery degradation over time.
And just for reference, I've included a couple charts below to show people what I'm dealing with. By the way this is a droid turbo which is supposed to be a 48-hour life span but as you'll see I've got just about 8 hours out of it and I'm already at 20%. This is exactly the reason that I baby my battery and I'm looking to get as much out of it in life span as I can, as well as in runtime per charge.
Your results may vary, and your decisions whether or not to baby your battery will likely be influenced by those results. I'm just trying to give people some understanding of the hows and whys and if they choose to use my information that's up to them.
