the annular electrolytic cell 12 is filled with electrolyte; the annular electrolytic cell 12 includes a cell membrane 121; the cell membrane 121 serves to divide the electrolyte into a cathode chamber and an anode chamber; the cathode chamber and the anode chamber are respectively provided with a cathode plate 122 and an anode plate 123; a monitoring unit (such as a voltage monitoring unit) may be further disposed between the cathode plate 122 and the anode plate 123; the rotatable magnetic circuit 11 includes a rotation shaft 111 passing through a circular hole surrounded by the annular electrolytic cell 12 (i.e., an annular hole of the annular electrolytic cell 12), and a pair of pole shoes (i.e., a first pole shoe 112 and a second pole shoe 113) respectively located on both sides of and perpendicular to the electrolytic cell diaphragm; the transmission part 13 drives the rotating shaft 121 through the prime motor 01 to drive the pole shoe pairs to rotate on two sides of the annular electrolytic cell 12; the rotation of the rotatable magnetic circuit 11 causes an induced potential and an induced current to be generated between the electrolytes on both sides of the cell membrane 121.
In the prior art, in the working principle of electrolytic power storage, a direct current power supply is generally adopted to supply power to two electrode plates in an electrolytic cell, so that potential and current are generated between electrolyte at two sides of a diaphragm of the electrolytic cell, and then the electrolyte is subjected to electrochemical reaction to convert electric energy into chemical energy so as to realize power storage and energy storage.
As shown in fig. 2, the application scenario of the embodiment of the invention is that the electric storage device is directly linked with the prime motor, a direct current power supply is not required to be arranged, and induced potential and induced current are directly generated between electrolyte at two sides of the diaphragm of the electrolytic cell, so that the electrolyte is subjected to electrochemical reaction; taking a wind turbine as an example of a prime motor, the working principle of the embodiment of the invention is that when the wind turbine outputs mechanical energy, the transmission part 13 can drive the rotating shaft of the rotating magnetic circuit 11 to rotate, and at the moment, the rotatable magnetic circuit 11 drives one or more pairs of pole shoes respectively adjacent to the cathode chamber and the anode chamber of the annular electrolytic cell 12 to rotate; since the annular electrolytic cell 12 is stationary, when the pole shoe pair rotates, the rotating magnetic field between the pole shoe pair will be cut by the electrolyte in the annular electrolytic cell 12, thereby generating induced potential and induced current in the electrolyte, and causing electrochemical reaction of the electrolyte.
In practical use, as shown in fig. 3, the cross section of the annular electrolytic cell 12 may be rectangular; in addition, the cross section of the annular electrolytic cell 12 may be an annular electrolytic cell.

It should be noted that, the number and the size of the sub-cavities in the embodiments of the present invention may be set by those skilled in the art according to needs, and are not limited herein.
Further, in the embodiment of the present invention, the transmission component further includes a speed change mechanism (not shown in the figure); the rotating speed change mechanism is arranged between the prime motor and the rotating shaft and is used for controlling the rotating speed of the rotating shaft.

Further, in the embodiment of the present invention, an inverter (not shown in the figure) may be further connected to the dc output interface, so that ac power output to the load may be achieved.
In summary, in the embodiment of the invention, the power storage device for the prime mover is provided, in which the electrolytic cell is provided in a ring shape, and the rotatable magnetic circuit capable of generating the induced potential and the induced current in the electrolyte between the cathode chamber and the anode chamber of the ring-shaped electrolytic cell when rotating is provided, so that the induced potential and the induced current for electrolytically storing the electrolyte can be generated in the electrolyte by the mechanical energy drive of the prime mover after the transmission member is provided in transmission connection with the prime mover.
The electrolytic cell of the invention does not need to be provided with a direct current power supply, can directly convert the mechanical energy of the prime motor into electrochemical reaction energy, and reduces the energy conversion links, so that the structure of the electric storage device can be effectively simplified, and the energy loss caused by energy conversion is reduced.

In practical applications, the prime mover 01 in the embodiment of the present invention may specifically include a gas turbine, a steam turbine, a wind turbine, an internal combustion engine, or the like.
