The invention discloses a hydrophobic modified lithium titanium aluminum phosphate powder material as well as a preparation method and application thereof. According to the hydrophobic modified lithium titanium aluminum phosphate powder material, the moisture content of an LATP material is reduced through a hydrophobic modification method, and the problem of water absorption of the LATP material is solved. Moisture content is an important index in the production process of a lithium ion battery, when the moisture content of a lithium ion battery raw material exceeds the standard or excessive moisture is introduced in the production process, a large amount of HF is generated in the battery, the HF has very strong corrosivity, and the durability and the service life of the battery can be seriously reduced. Through hydrophobic modification of the LATP material, on one hand, the moisture content in the LATP material can be reduced, and on the other hand, the water absorption problem of the LATP material in the st
