This invention discloses a method for preparing nano-aluminum-based
lithium materials and adsorbents using laminar
plasma beams, belonging to the field of
lithium-
ion adsorption technology. This invention provides a simple, relatively mild, and highly repeatable method for preparing nano-aluminum-based
lithium materials and adsorbents using
plasma beams. In this invention, aluminum
hydroxide and
lithium chloride are mixed in a
molar ratio of 2:1 to 1.3, and then evaporated and condensed by a
plasma beam in a sealed space protected by an
inert gas to obtain nano-aluminum-based lithium materials. These materials are then granulated with resin to obtain the adsorbent. This invention uses the controllable laminar arc heat generated by the
plasma beam as a heat source, achieving physical high-temperature
vaporization and simultaneous rapid condensation to form Al(OH)₂. 3 The
nanomaterials with uniformly distributed LiCl molecules maximize the specific surface area of the aluminum-based lithium adsorbent, resulting in superior adsorption capacity. This invention is produced in a fully enclosed manner under normal pressure, offering advantages such as safety, zero emissions, energy saving,
environmental protection, short process, and continuous, efficient, and stable preparation.
