Picture of a disassembled Duracell 9v battery. Below the terminal assembly is a clear plastic case where you can see six sets of stacked rectangular terminals and fillings.

Those super expensive rechargeable batteries they sell for cordless power tools have smaller cylindrical batteries inside, wired together.
The Torque Test Channel on YouTube took some apart for their insane Dewalt backpack battery modification video. It’s a fun watch.
Open any lithium battery pack and you’d find those cylindrical lithium cells. Even a Tesla battery has those. Only things that need to be flat like a laptop or a phone use a pouch battery.
On older laptops they used cylindrical cells too. On mine, you can clearly nake out the shape of the housing on the removable battery.
Used to repurpose the individual cells of laptop batteries for ecig batteries. The cells were 18650s, same as most customizable ecig mods use.
