Abstract: A steerable drilling device has an outer tube extending along a longitudinal axis; a drill bit joint inserted into said outer tube, a lower end of said drill bit joint extending out of a lower end of said outer tube for connection to a drill bit; a joint drive mechanism, provided in said outer tube and configured to drive said drill bit joint to swing relative to the longitudinal axis; and a lower connection mechanism. The lower connection mechanism has a connection body connected to said joint drive mechanism in such a manner that said joint drive mechanism is non-rotatable with respect to said connection body, a first centralizer arranged between said connection body and said outer tube, a circuit system arranged in said connection body and configured to provide an electrical signal to said joint driving mechanism, and an attitude sensor arranged in said connection body.

Abstract: The present disclosure discloses a modified high-nickel cathode material, where the modified high-nickel cathode material is a SO42?-doped modified high-nickel cathode material, and SO42? is distributed in a secondary particle with a content gradient from high inside to low outside. A preparation method of the modified high-nickel cathode material includes: mixing a high-nickel cathode material, a lithium source, and a sulfate, and sintering a resulting mixture to obtain a matrix material; and water-washing and drying the matrix material to obtain the modified high-nickel cathode material. The present disclosure increases a migration rate of lithium ions in the material and greatly improves the initial capacity of the material, which reduces an energy barrier for migration of lithium ions, increases a migration rate of lithium ions among primary particles of the material, and improves the safety performance of the material.

Abstract: A production control method and apparatus, an electronic device and a storage medium are provided. The method includes: acquiring a first quantity of materials to be treated that correspond to a first process device, wherein said materials are target materials which have entered the first process device but have not entered a second process device, and the second process device is a process device in the next procedure after the first process device; on the basis of the current process state of the second process device, predicting a second quantity of target materials which can be treated by the second process device during a preset process duration corresponding to the first process device, wherein the second process device can process a fixed quantity of target materials in each working state; controlling a feeding action of the first process device according to the first quantity and the second quantity.
