This invention discloses a method for preparing interface-reinforced niobium pentoxide / porous graphene and its energy storage application. The method involves adding porous graphene oxide during the solvothermal synthesis of a niobium pentoxide precursor to obtain a composite precursor of niobium pentoxide and porous graphene oxide. This precursor is then annealed under a protective atmosphere to obtain the interface-reinforced niobium pentoxide / porous graphene composite material. The composite material obtained by this invention exhibits excellent performance as an electrochemical energy storage material. Furthermore, the preparation method of this invention is simple to operate, requires no complex equipment, and is easily controlled, making it suitable for mass production.

The invention relates to the technical field of crystallization control, and discloses a programmed cooling crystallization kettle and method capable of regulating and controlling sugar alcohol crystal granularity, and the method comprises the following steps: constructing a basic nonlinear cooling model in advance, and respectively collecting real-time torque and actual average chord length of the crystal by using a torque sensor and a focused light beam reflection measurement probe in the crystallization process; and the control system calculates the cooling rate correction according to the granularity deviation through a PID algorithm, calculates a rheology correction factor according to the torque change, and performs attenuation treatment on the sum of the basic rate and the correction by using the rheology correction factor to obtain a final cooling instruction to adjust the temperature in the kettle.
