Lithium iron phosphate positive electrode material, preparation method thereof and battery
PendingCN121929676AIncrease compaction densityCoated evenlyGraphiteCell electrodesLithium iron phosphateElectrical battery
The invention discloses a lithium iron phosphate positive electrode material, a preparation method thereof and a battery, and belongs to the technical field of batteries, the preparation method comprises the following steps: mixing an iron source, a lithium source, a phosphorus source, a dopant and a grinding agent, and carrying out dry ball milling to obtain precursor powder; and sintering the precursor powder under the protection of inert gas to obtain the lithium iron phosphate positive electrode material. According to the method, high-purity graphite / acetylene black is used as a grinding agent and a carbon source, a doping agent is added at the same time, a solvent does not need to be used, a ball-milled material does not need to be dried, uniform compounding of a precursor and construction of a conductive network are achieved in one step through the mechanochemical effect, and then the conductive network is obtained through high-temperature sintering. The prepared lithium iron phosphate positive electrode material has excellent electrochemical performance and relatively high compaction density, and still keeps relatively good electrochemical performance in a low-temperature environment, so that a new development direction is provided for production of lithium iron phosphate.

Security and protection monitoring comprehensive early warning analysis system and method based on machine learning
PendingCN121808549AEfficient removalimprove data qualityCharacter and pattern recognitionBiological modelsThe InternetEngineering
The invention relates to the technical field of image recognition and analysis, solves the technical problems that implicit spatial dependence is difficult to capture, missing report group conflicts are caused, and recognition of progressive abnormal behaviors is prone to delay or misjudgment in the prior art, and particularly relates to a security and protection monitoring comprehensive early warning analysis system and method based on machine learning. The method comprises the following steps: S1, collecting an original video stream monitored in a campus, obtaining campus Internet of Things sensor data, and preprocessing the original video stream and the Internet of Things sensor data to obtain time-space standardized data. According to the method, spatial configuration and time evolution can be explicitly coded, information splitting can be avoided, long-distance and many-to-many complex dependence can be captured in a cross-frame mode, the understanding accuracy of group abnormal behaviors is improved, robustness is greatly improved, and the joint analysis capacity of individual behavior and group interaction is remarkably improved.
