Tanks
Tanks are the part of an ecigarette that hold E-Liquid and atomizers. A tank will have either a screw thread or push fit style inner chamber - in both cases the atomizer (coil) serves as a barrier. The positive pressure of gravity will encourage the E-Liquid down into the cotton of the coil, but without 'sealing', the tank is still susceptible to leaking.
A top cap prevents leaking by creating a vacuum - as the cotton and positive pressure pull the E-Liquid down, an air pocket of negative pressure forms at the top of the chamber, creating an equal pull of pressure that allows the coil to get soaked well without any leaking.
Tanks often have options for bubble glass to increase the capacity up from the legally required 2ml - a rule that was put in to effect following the TPD, a set of directives published by the EU regulating the import and export of vape related products.
Sub Ohm Tanks
Sub Ohm tanks are a subset of vape atomizers that fall below the 1ohm mark in terms of resistance. Many sub ohm tanks now have coils that measure around 0.1-0.3Ohm resistance.

The low resistance of a coil requires a higher wattage (and current) in order to heat the coils up quick enough. As a result a sub ohm tank is mostly always paired with a dual or higher battery external box mod. A single battery internal or external can also be used, but battery degradation is significantly more noticeable, leading to frustration and an increased risk of relapsing into smoking.
Sub Ohm Tanks also increasingly have mesh coils available - mesh coils tend to heat the cotton more evenly and with a quicker firing time. They can also contribute to better flavour, as seen with the Freemax Mesh Pro tank and Horizon Tank Falcon Tank.
