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.

This utility model discloses a high-strength magnetic pump isolation sleeve, relating to the technical field of magnetic pump isolation sleeves. It includes an outer sleeve and an inner sleeve fitted inside the outer sleeve. Both the outer and inner sleeves have communication openings at their tops. The inner sleeve's inner wall is provided with anti-vortex guide plates to reduce fluid resistance. The bottom of the inner sleeve has a buffer pad with multiple vents. A fastening bolt is screwed onto the bottom of the outer sleeve, and multiple reinforcing ribs are fixed to the bottom of the inner sleeve. This utility model significantly improves the sealing performance of the isolation sleeve through the use of protrusions; ensures stable installation through the use of threaded posts; and significantly reduces fluid flow resistance, improves the delivery efficiency of the magnetic pump, reduces energy consumption, and minimizes energy loss and mechanical vibration caused by vortices. This solves the problems of high flow resistance and low delivery efficiency caused by fluid vortices in traditional isolation sleeves.
