Abstract: A positive electrode active material precursor includes Ni and Mn and secondary particles formed by the aggregation of a plurality of primary particles. The secondary particles have a ratio of a core area to a total area of the particles ranging from 28.7% to 34.1%, and a porosity ranging from 11.3% to 11.7%. Also provided is a method for preparing the positive electrode active material precursor. Additionally, a positive electrode active material including a reaction product of the positive electrode active material precursor and a lithium raw material is provided. Also provided is a method for preparing a positive electrode active material using the positive electrode active material precursor.

Abstract: A home appliance includes a housing including an inlet, a first outlet formed in the housing to discharge air introduced through the inlet, a second outlet disposed adjacent to the first outlet, a fan assembly including a first fan configured to discharge air toward the first outlet, and a second fan configured to discharge air toward the second outlet, and a stator provided to guide air, which is discharged from the first fan, to the first outlet.

Abstract: The present disclosure relates to an air conditioner capable of inducing airflow blown through a blowing port to blow in a substantially horizontal direction. The air conditioner includes a housing including a blowing port, and an airflow guide unit installed in the blowing port to be rotatable about a rotation shaft, wherein the airflow guide unit includes a main blade configured to cover the blowing port, and a pair of sub blades spaced downwardly apart from the main blade and disposed in a flow passage of the blowing port such that outer surfaces thereof are in contact with airflow in the blowing port as a whole, and having different inclination angles.

Abstract: A fan guard assembly having an improved structure for providing improved performance and an outdoor unit having the same are provided. The fan guard assembly includes: a front panel having an outlet; and a fan guard including a hub provided at the outlet to directly fix a fan motor assembly and a rib connecting between the hub and the front panel. Further, the outdoor unit includes: a cabinet; a bell mouth provided in the cabinet; a fan guard provided at an outlet of the bell mouth; and a fan motor assembly fixed to the fan guard.

Abstract: Disclosed is an air cleaner having an improved boss for increasing rigidity. The air cleaner includes a main body, a blowing fan provided inside the main body, a motor for driving the blowing fan and a boss provided to connect the blowing fan and the motor. The boss includes a first metallic member connected to the blowing fan, a second metallic member connected to the motor, and an elastic member provided between the first metallic member and the second metallic member. At least one of the first metallic member and the second metallic member includes a contact increasing portion configured to increase a contact area with the elastic member.

Abstract: A propeller fan that includes a hub body with a shaft coupling portion. The propeller fan also includes a plurality of hub blades extending spirally from the hub body. The propeller fan additionally includes a plurality of blades extending outward from the hub body and the hub blade to generate an airflow in an axial direction.
