- a conductive consumable for an aerosol generating device, which enables operating an aerosol generating device with a rechargeable, e.g. lithium-ion, battery without requiring a heating system or lighter to be part of the device.
- the objective of the invention is to provide a method for manufacturing the men- tioned conductive consumable, the aerosol generating device for use with the consumable and a method for production of aerosol.
- a consumable for an aerosol generating device comprises a heat ing element and especially a heating layer of an aerosol substrate formed to be positioned in sandwich between two electrodes of the device.
- the heating layer of aerosol substrate com prises a flavorant material and an aerosol forming agent.
- the consumable is characterized in that the layer further comprises electrically conductive material in particulate form embedded in the layer, wherein the electrically conductive mate rial is arranged in the heating layer to conduct electrical current between the two electrodes and/or to heat the aerosol substrate to a temperature sufficient to aerosolize the aerosol forming agent.
- the flavorant material comprised in the heating layer comprises natural and/or synthetic components which enhance and modify the taste of the generated aerosol.
- the flavorant material comprises tobacco material which preferably can be manufactured from different types of tobacco plants. However, it is not essential to add the tobacco material to the flavorant material.
- the consumable is arranged between two electrodes, more preferred the consum able is pressed between the electrodes.
- the two electrodes preferably represent common electrodes for use as a heater in the aerosol generating device.
- the consumable, in particular the heating layer is formed as a paste or dough. It is advantageous to provide the consumable in this shape at least because of the various storage possibilities.
- the consumable in form of the dough is preferably provided or stored as a layer which is rolled up on itself similar to a spiral or a hyperbolic spiral. It is also possible to provide the consumable rolled on a bobbin.
- the whole consumable and especially the heating layer of an aerosol substrate is stored in a cartridge which is preferably intended for keeping the consumables fresh.
- the cartridge is preferably provided with a mechanism to open and close the cartridge. Various closures are available for this purpose. Due to this it is conceiva ble that the cartridge is refillable with the consumable in particular the heating layer.
- the consumable provided as a paste comprises a viscosity of up to 10 2 mPas (at 20°C).
- the - preferably dynamic - viscosity of the consumable preferably decreases with increasing tem perature of the electrodes. It is conceivable that the consumable is a non-Newtonian fluid and comprises solid particles. Depending on the composition of used materials of the con sumable, an amount of the solid particles varies. Due to this the viscosity and in particular dynamic viscosity of the consumable preferably depends on the ingredients and the amount of the comprised solid particles in the consumable.
- the two electrodes of the aerosol generating device are connected to a voltage source.
- the voltage source supplies the whole aerosol generating device with electrical energy providing a voltage in range of 1 V and 5 V.
- the voltage source is a lithium-ion battery delivering a value of 3.7 V.
- Such a voltage source is particularly advantageous for a modern aerosol generating device in view of rechargeability.
- the heating layer according to the invention appears as a conductor between the electrodes and provides a direct aerosolization of the consumable.
- the two electrodes and the heating layer reach a temperature in range of 90 to 230°C for a sufficient aerosolization of an aerosol forming agent comprised in the consumable.

- the smaller electrode contact surfaces prefera bly comprise a contact surface area in range of 150 mm 2 and 200 mm 2 . In this case it is pos sible to increase the quantity of the electrically conductive material in the heating layer. Due to this the electrodes with the large electrode contact surface should be used preferably with a heating layer comprising a lower quantity of the electrically conductive material.
- the large electrode contact surfaces comprise a contact surface area in range of 250 mm 2 and 320 mm 2 . In the preferred embodiment the electrode contact surfaces area are in range of 200 mm 2 to 250 mm 2 , more preferred comprise 215 mm 2 .

- the thickness of the heating layer corresponds to the thickness of the whole consumable.
- the heating layer is preferably not formed as a separated layer but is distributed in the whole consumable. Due to this, the whole consumable compris ing electrically conductive material is a heating layer.
- the maximum thickness of the con sumable is preferably determined by a design of the aerosol generating device. There is of ten little space available in the small aerosol generating devices, so the thickness of the con sumable is particularly important. Due to this the preferred thickness of the consumable is particularly advantageous for storage in the cartridge.
- the narrow thickness of the consumable enables a greater capacity of the cartridge compris ing the consumable. At the same time, less electrical voltage and less heating time is prefer ably needed to heat the consumable. This allows a user to use a single cartridge with the consumable for a longer period of time. A further advantage for a preferred thickness of the consumable or the heating layer would be a compact winding in the cartridge. This helps to avoid wasteful voids in the cartridge with the consumable.
- the consumable is characterized in that the electrically conductive material is distributed in and on the layer in an amount to allow electricity to flow from one electrode through the thickness of the layer to the other electrode.

- the conduc tive material or the heating layer is a solid material, preferably provided in form of the dough, the conductive material is preferably anisotropically distributed inside the heating layer of the consumable. This leads to the formation of areas with a higher and a lower concentration of conductive material inside the heating layer or the consumable.
- the electrically conductive material inside the heating layer of the con sumable is dispersed to the extent that the current flow is ensured.
- the distribution of the conductive material inside a more liquid consumable, preferably in form of a paste, can ad vantageously be better compared to the distribution inside the solid consumable.
- the conductive material is evenly dispersed inside the liquid consumable. This can be achieved through a liquid electrically conductive material or conductive particles dispersed in a carrier liquid.
- the electrically conductive material is graphite or charcoal particles.
- the material may take the form of powder, loose or agglomerated particles. It is also conceivable to use other conductive materials which are approved in particular at least in the tobacco industry or food industry.

- the electrically conductive material comprises the amount of 2.5 to 59 % wt. regarding to the consumable.
- the amount of present carbon or charcoal particles in the con sumable or the heating layer depends at least on the thickness of the consumable or the heating layer. It is also conceivable that the amount of present carbon or charcoal particles in the consumable depends on provided pressure between the first and the second electrodes during the heating process. It is possible that the consumable comprises both the carbon and the charcoal particles.
- the amount of both materials in the heating layer or the consumable is preferably present in range of 5% and 40% wt., also preferred 2.5% and 60% regarding to the consumable. In general, it is conceivable to use a greater amount than 50% wt. of the carbon and/or the charcoal particles in the consumable or the heating layer.
- the electrically conductive material may have a hollow structure.
- the hollow structure can be formed by pores or tubes or another capillary or spongy structure. The advantage of such structure is that it can provide a reserve for aerosol forming agent without softening the con sumable.
- the heating layer further comprises a binder, preferably carboxymethyl cellulose (CMC), in an amount between 0.5 and 2.5 wt.% regarding to the consumable or the heating layer.
- CMC carboxymethyl cellulose
- the consumable preferably comprises a binder as CMC in an amount between 0.5 and 2.5 wt.% regarding to the consumable.
- the binder is comprised in an amount of about 1.74 wt. % of the total weight of the con- sumable. It is conceivable to use other binders, for example a mixture of cellulose gum, wa ter and glycerine. Water enables to activate the binder and its amount can vary according the binder selected.
- the aerosol forming agent comprises an amount of less than 25 % wt. regarding to the consumable or the heating layer.
- the aerosol form ing agent is glycerin and/or propylene glycol. Due to this, it is possible not to add the aerosol forming agent to the consumable or the heating layer.
