The invention provides a battery positive electrode powder conveying device, which comprises a feeding mechanism comprising a feeding wheel for conveying positive electrode powder and a first motor for driving the feeding wheel, a tableting mechanism comprising two tableting wheels which are symmetrically and vertically distributed, a second motor for simultaneously driving the two tableting wheels, and a current transducer which is arranged on the second motor and is used for detecting the second motor, a main controller which is respectively connected with the current transducer, the first motor and the second motor, and in which a frequency converter is arranged. The battery positive electrode conveying device has the advantages of reliable work, and effective improvement on the situation that positive electrode sheets are different in thickness when the positive electrode powder is molded by tableting.
