As the core component of the tobacco heating appliance, the energy supply components determine its key parameters, such as the components life, charge-discharge speed, preheating waiting time and service life. This paper summarizes the development status of energy supply components of heating appliances in electric heating tobacco products, and analyzes two kinds of energy supply components shortcomings and potential research direction. The results show that lithium-ion battery, as an energy supply component commonly used in electric heating cigarette heating appliances, possess the characteristics of high bulk energy density and large discharge current. However, it also has some disadvantages, such as low charge-discharge speed, poor cycle stability, high cost as well as potential safety hazards. As a potential energy supply component of heating appliance in electric heating cigarette, dielectric capacitor possess the performance of fast charge-discharge speed, excellent cycling stability, high reliability, cheap price and good safety, but its bulk energy density needs to be quickly improved. Energy supply components are the key units in tobacco heating appliances. Paying attention to the development and research of energy supply components is very significant to promote the new tobacco products in China high-quality development and improve the consumer experience. |
