Abstract: A high-nickel ternary positive electrode material, has a structural formula of LixNiaMbCocNzO2. A content of a cobalt element within a range of 1.5 ?m from a surface of the positive electrode material accounts for 48%-85% of a content of the cobalt element in the positive electrode material. A high-nickel ternary positive electrode material is designed in the present application, which has a specific structure with cobalt element distributed gradiently from inside to outside, and thus a high-nickel low-cobalt positive electrode material product with good stability can be directly obtained. The content of cobalt in the near-surface region and surface region of the positive electrode material is high, and high-content cobalt may react with Li+that cannot be re-inserted to generate lithium cobaltate. This increases part of the capacity and avoids the generation of residual alkali, thereby improving the capacity and cycle performance of the high-nickel ternary positive electrode material.

Abstract: This application provides methods and apparatus for sending feedback information. By binding a BAR-BA feedback manner, that is, first a request and then a feedback, when it is determined that data retransmission is performed by using a hybrid automatic repeat request (HARQ) mechanism, duration of an acknowledgment operation performed by a data receive end on retransmitted data may be increased. Alternatively, the receive end estimates duration required for feeding back a receiving status of the retransmitted data, and feeds back the duration to a transmit end. The transmit end may therefore adaptively adjust duration of the retransmitted data based on a feedback capability of the receive end, to ensure that the feedback of the receive end on the receiving status of the retransmitted data is within a short inter-frame space (SIFS).
