This invention provides a cobalt tetroxide with a compact inner structure and a loose outer structure, its preparation method, and its application. The preparation method includes the following steps: first, a reaction solution containing seed crystals is prepared; then, a second cobalt-aluminum mixed salt solution and a second precipitant solution are co-flowed into the reaction solution containing seed crystals to perform a crystal growth stage, obtaining a reaction solution containing a first intermediate; subsequently, a salt solution containing doped elements, a third cobalt-aluminum mixed salt solution, and a third precipitant solution are co-flowed into the reaction solution containing the first intermediate to perform a second co-precipitation reaction, obtaining a second intermediate; finally, the intermediate is calcined to obtain the cobalt tetroxide with a compact inner structure and a loose outer structure. This preparation method, by controlling the reaction conditions in stages, obtains a cobalt tetroxide with a compact inner structure and a loose outer structure, meeting the requirements for high tap density, high structural strength, and good conductivity, thereby improving the energy density and electrochemical performance of lithium-ion batteries.

The application discloses a planning method for finished piece cigarette box loading of a truck, comprising the following steps: constructing a calculation model of a single finished piece cigarette box stacking mode and a calculation model of two finished piece cigarette box matching degrees and corresponding stacking modes; using the calculation model of the single finished piece cigarette box stacking mode to calculate whether the current type finished piece cigarette box of the current group order can be stacked into a cuboid, and if yes, stacking the current type finished piece cigarette box into a cuboid in the stacking mode, otherwise, calculating whether stacking in a conventional stacking mode is an integral row, and if yes, stacking in the conventional stacking mode, otherwise, using the calculation model of the two finished piece cigarette box matching degrees and corresponding stacking modes to calculate all types of finished piece cigarette boxes which can be used as the next loading of the truck and corresponding stacking modes with the highest matching degree of the current type finished piece cigarette box of the current group order. The problem of mixed stacking and loading of the truck of multiple specifications and multiple destinations is solved.
