According to an exemplary embodiment, provided is an aerosol generating device including a body portion comprising a vaporizer configured to generate aerosol by heating a liquid composition; and one or more air flow paths configured to cause the generated aerosol to pass through a cigarette and be discharged to outside; and a cover coupled to the body portion and comprising a plurality of passages comprising a first passage and a second passage which are independent from each other and guide air to an entrance of the vaporizer along at least part of a surface of the body portion.

Aerosol generating device

The present invention relates to a method of producing lithium hydroxide from a lithium concentrate through sodium sulfate addition and roasting. The method effectively recover lithium ions from the lithium concentrate, minimizes production of byproducts, and produces high-purity lithium hydroxide. By mixing a concentrate containing lithium with sodium sulfate (NaSO), roasting the concentrate, and leaching the roasted concentrate with water, it is possible to recover lithium ions at a high recovery rate and to produce high-purity lithium hydroxide monohydrate.

Method of producing lithium hydroxide from lithium concentrate through sodium sulfate addition and roasting

Provided is a heater assembly for aerosol generating devices, the heater assembly including a thermally conductive element that has a cylindrical shape and includes an accommodation space for accommodating a cigarette, a flexible heater that surrounds at least a portion of an outer surface of the thermally conductive element, and an adhesion member that surrounds the flexible heater such that the flexible heater closely adheres to the thermally conductive element.

A method according to an embodiment is for recovering a valuable metal from a waste electrode material of a lithium secondary battery by using lithium carbonate. An anode-cathode mixed electrode material that has been separated by draining, crushing, screening, and sorting a waste lithium secondary battery is preprocessed. A precipitation operation performed by adding lithium carbonate (Li2CO3) to a metal melt acquired by performing sulfuric acid dissolution using sulfuric acid. A valuable metal such as nickel, cobalt, manganese, aluminum, and copper is recovered as a residue in the form of a carbonate composite, and a lithium sulfate (Li2SO4) aqueous solution including lithium is recovered as a filtrate.
