  • Methods for preparing two-dimensional sheet-like LiSiOadsorbents using attapulgite and waste lithium batteries
    Patent number: 12344532
    Abstract: A method for preparing two-dimensional sheet-like Li4SiO4 sorbent, including: obtaining LiCoO2 by performing discharging, aluminum foil stripping, and sieving on waste lithium battery cathode material, and drying; obtaining biomass by freeze-drying waste biomass, and grinding and sieving the freeze-dried waste biomass; mixing LiCoO2 and the biomass uniformly to obtain a mixture, and putting the mixture into a tube furnace for nitrogen purging, heating and calcination, and carbothermal reduction to obtain a solid sample, hydrothermal stirring the solid sample, followed by filtering, and evaporating to obtain Li2CO3; ultrasonically dispersing the attapulgite in an acid solution, and stirring in a water bath at 80° C.
    Type: Grant
