The invention discloses a method for preparation of battery grade 
lithium chloride from 
spodumene leachate. The method includes the steps of: A, adding a 
sodium hydroxide solution into a 
lithium sulfate spodumene leachate solution to adjust the PH to 10-13, adding 
sodium carbonate for reaction, and performing press 
filtration to obtain a primary 
lithium sulfate refined solution; B, subjecting theprimary 
lithium sulfate refined solution to 
calcium removal by chelate resin to obtain a secondary 
lithium sulfate refined solution; C, adding 
barium chloride dehydrate into the secondary 
lithium sulfate refined solution to obtain a primary 
lithium chloride solution; D, adding 
sodium carbonate into the primary 
lithium chloride solution, and conducting press 
filtration separation to obtain a secondary 
lithium chloride solution, and performing acidification and steam stripping to obtain a lithium 
chloride refined solution; E, conducting triple-effect 
evaporation on the lithium chloride refined solution to obtain a lithium chloride concentrated solution; F, subjecting the lithium chloride concentrated solution to freezing cooling to precipitate sodium and 
potassium, thus obtaining a final lithium chloride solution with 
low sodium and 
potassium; and G, carrying out concentration and separation on the final lithium chloride solution, and subjecting the obtained 
solid to 
drying so as to obtain a battery grade lithium chloride product. The method for preparation of battery grade lithium chloride from 
spodumene leachate provided by the invention has the characteristics of simple process, high purity of finished product, stable product quality, low cost and high yield.
