  • Publication number: 20230416198
    Abstract: The present disclosure provides a method for continuously and efficiently preparing taurine, including:(a) bringing an ethylene oxide with an alkali metal bisulfite into an addition reaction to obtain an alkali metal isethionate; (b) bringing the alkali metal isethionate with an ammonia into an ammonolysis reaction to obtain a solution containing alkali metal taurinate; and (c) inputting the solution containing alkali metal taurinate into at least one acid cation exchange resin column in activated state to obtain the taurine through an acidification treatment, followed by activating a portion of the at least one acid cation exchange resin column by a first activation manner using sulfurous acid and obtaining a solution containing alkali metal bisulfite, and activating another portion of the at least one acid cation exchange resin column by a second activation manner using sulfuric acid, wherein the first and second activation manner may be performed on a same acid cation exchange resin column alternatingly or

  • Publication number: 20230416110
    Abstract: Provided are ternary positive electrode material precursor and preparation method thereof, ternary positive electrode material, lithium-ion battery, positive electrode, and electric-involved equipment. The precursor includes, sequentially from inside to outside, core layer, first intermediate layer, second intermediate layer, and shell layer. Porosities of core layer, first intermediate layer, and second intermediate layer increase sequentially. Shell layer has the smallest porosity or no porosity. The method includes: performing first reaction of raw materials including nickel-cobalt-manganese ternary metal salt mixed solution, complexing agent, and pH modifier to obtain core layer; performing second reaction to form first intermediate layer on surface of core layer; performing third reaction to form second intermediate layer on surface of first intermediate layer; and performing fourth reaction to form shell layer on surface of second intermediate layer.
