Abstract: The present invention is a semi-solid state battery and a preparation method therefor. In the method for preparing the semi-solid state battery of the present invention, due to different polymerization rates of two different reactive monomers, polymers with different chain lengths and molecular weights are generated. Self-assembly stratification of an electrolyte occurs gradually with polymerization reaction time and in-situ curing time, and the self-assembly stratification of an entire cell system also occurs gradually over time. Interfaces between upper and lower polymer layers achieve mutual penetration and uniform transition to form an interface-free state beneficial for tighter and stronger bonding between the two layers. The comprehensive electrolyte structure can improve safety and cycle stability of the in-situ polymerization battery. By adopting the self-assembled in-situ polymerization method, interfacial impedance between the electrolyte and electrodes inside the battery is reduced.

Abstract: Provided is a spatiotemporal data augmentation method for a recommendation system. The method explicitly summarizes spatiotemporal features of users and items and uses a large model as an encoder to unify embeddings in a single vector space; then uses a linear layer to align feature dimensions for fusion into a recommendation model, thereby solving the problem of insufficient feature fusion. The method leverages the large model to comprehend an interaction history and a candidate set of a user, infers preferences of the user and generates positive and negative sample pairs, and merges the generated sample set with an original sample set to form a final training set. Benefiting from the excellent reasoning and natural language understanding capabilities of the large model, the method achieves both expansion of the training sample set and mitigation of a noise issue.
