Zusammenfassung:	Disclosed in the present application are a lithium battery separator and a manufacturing method therefor. The lithium battery separator of the present application comprises a base film and a functional ceramic layer. The functional ceramic layer at least comprises a functional component 1, and the functional component 1 is selected from at least one of Li1-x1Ti1-x1Ax1OPO4, Li1-x1Ti1-x1Ax1PO5, Li2-x2Ti1-x2Ax2OM1O4 and Li2-x2Ti1-x2Ax2M1O5, wherein 0≤x1≤0.7, 0≤x2≤1, A comprises at least one of Nb, Ta and Sb, and M1 is at least one of Si and Ge. The functional ceramic layer may further comprise a functional component 2. The functional ceramic layer is formed by coating a slurry of the functional component 1 or a mixed component composed of a combination of the functional component 1 and the functional component 2, and the slurry comprises, in percentage by weight, 5%-45% of a coating material and 55%-95% of a solvent. The coating material comprises the following components in parts by weight: 100 parts of the fun
