Abstract: A data processing method and apparatus are described. The data processing apparatus obtains an input tensor corresponding to input data. The data processing apparatus determines M1 first-type tensor blocks and M2 second-type tensor blocks. P processing units in the data processing apparatus process the M tensor blocks concurrently. In a first time period, all of the tensor blocks that are processed concurrently by the P processing units are first-type tensor blocks. In a second time period, all of the tensor blocks that are processed concurrently by the P processing units are second-type tensor blocks.

Abstract: A preparation method of CsDFP for aqueous negative electrode slurry includes carrying out ion exchange reactions with LiPO2F2 and a cesium source. The activation energy of Li+ intercalation in the negative electrode is reduced due to the existence of Cs+, leading to a better rate performance. Further, the impedance growth rate of the batteries is reduced and the high temperature storage performance is excellent since PO2F2— participates in the electrochemical reaction to form a stable low-impedance SEI film on the surface of the negative electrode plate. Moreover, films are continuously formed to repair the SEI films under the gradual release of CsDFP, which is conducive to inhibiting the growth of lithium dendrites during long-term high-rate cycling, thereby obtaining an improved cycle performance.

Abstract: The present invention relates to an electrolyte additive, a non-aqueous electrolyte and a lithium ion battery using same. The electrolyte additive includes a compound represented by Formula 1: In Formula 1, R1, R2, R3, and R4 are each independently hydrogen atom, halogen atom, a substituted or unsubstituted chain C1-C12 alkyl group, a substituted or unsubstituted chain C2-C12 alkenyl group, a substituted or unsubstituted chain C2-C12 alkynyl group, or groups represented by RCnH2n+1. R is each independently oxygen atom or sulfur atom, and n is positive integer. The electrolyte additive has a special structure. During the first charge and discharge process, redox products formed by oxidation-reduction reaction of multiple conjugated olefin structures adhere to the positive and negative electrode surfaces to form solid electrolyte interface films. The films have low impedance and high lithium ion conductivity, so the lithium ion battery has excellent rate performance and low temperature performance.
