An example of such products is a heating device, which releases compounds by heating rather than burning materials. For example, the materials may be tobacco or other non-tobacco products, and the non-tobacco products may or may not include nicotine. In another example, aerosol providing products exist, for example, the so-called electronic atomization devices. The devices usually contain a liquid. The liquid is heated and atomized, thereby generating inhalable aerosols. In a known electronic atomization device, a battery cell for supplying power is usually fixedly mounted in a shell of the device, to prevent a user from detaching or replacing the battery cell.
