Embodiment 1
[0021] Example 1: Lithium acetate, tetrabutyl titanate, SDS and water are uniformly mixed and put into a reaction vessel and sealed, wherein the molar ratio of lithium acetate to tetrabutyl titanate is 2:1, lithium acetate, titanate Tetrabutyl ester accounts for 20% of the weight of water, SDS accounts for 5% of the weight of water, and the total amount of lithium acetate, tetrabutyl titanate, SDS and water accounts for 80% of the filling degree of the airtight container. At a temperature of 180° C. for 24 hours, a white floc product of flower-like structure lithium titanate composed of nanosheets with a thickness of about 40 nm was finally obtained.
Embodiment 2
[0022] Example 2: Lithium acetate, tetrabutyl titanate, SDS and water are uniformly mixed and put into a reaction vessel and sealed, wherein the molar ratio of lithium acetate to tetrabutyl titanate is 2:1, lithium acetate, titanate Tetrabutyl ester accounts for 15% of the weight of water, SDS accounts for 5% of the weight of water, and the total amount of lithium acetate, tetrabutyl titanate, SDS and water accounts for 60% of the filling degree of the airtight container. At a temperature of 180° C. for 12 hours, a white floc product of flower-like structure lithium titanate composed of nanosheets with a thickness of about 30 nm was finally obtained.
Embodiment 3
[0023] Example 3: Lithium acetate, tetrabutyl titanate, SDS and water are uniformly mixed and put into a reaction vessel and sealed, wherein the molar ratio of lithium acetate to tetrabutyl titanate is 2:1, lithium acetate, titanate Tetrabutyl ester accounts for 10% of the weight of water, SDS accounts for 3% of the weight of water, and the total amount of lithium acetate, tetrabutyl titanate, SDS and water accounts for 80% of the filling degree of the airtight container. At a temperature of 180° C. for 12 hours, a white floc product of flower-like structure lithium titanate composed of nanosheets with a thickness of about 30 nm was finally obtained.
