[0058] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the drawings. Specific embodiments

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0060] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0061] In this application, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] In addition, in this application, the descriptions involving "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0063] The electrochemical test device can be used widely in electrochemical tests by performing high-throughput experiments to concurrently characterize multiple electrolyte formulations and complete the experimental data processing of multiple materials at the same time. However, when the electrochemical test device in the related art is in use, operations such as the addition of the electrolyte to be tested and the addition of the cleaning solution need to be manually completed. At this time, a large number of manual operations will interrupt the test experiment, resulting in a low test efficiency. At the same time, a large number of manual operations are also prone to errors, which affects the accuracy of the test results.

[0064] Therefore, based on the above considerations, in order to solve the problem that a large number of manual operations are required when the current electrochemical test device is in use, this application proposes a new type of electrochemical test device. The new type of electrochemical test device is innovatively provided with a liquid transfer mechanism to automatically inject the electrolyte to be tested and / or the cleaning solution into the electrolytic cell of the test module through this liquid transfer mechanism, thereby reducing the manual operations in the test process to improve the continuity of the test and thus the test efficiency, and at the same time reducing the manual operation errors to improve the accuracy of the test results.

[0065] Next, the structure of the electrochemical test device proposed in this application will be explained and illustrated with embodiments. In one embodiment of this application, please refer to Figure 1 and Figure 2, the electrochemical testing device 10 proposed in this application includes a testing module 11 and a liquid transfer mechanism 12; the testing module 11 is provided with an electrolytic cell 11a, and an electrode assembly 111 is arranged in the electrolytic cell 11a; the liquid transfer mechanism 12 is configured to inject the electrolyte to be tested and / or the cleaning liquid into the electrolytic cell 11a.

[0066] The testing module 11 can be used to form an electrolytic cell 11a to accommodate the electrode assembly 111 and the electrolyte to be tested subsequently through this electrolytic cell 11a. That is, through the testing module 11, an electrolytic testing environment can be provided for the electrolyte to be tested. Among them, the shape of the testing module 11 can be any shape such as rectangular, square or circular. Similarly, the shape of the electrolytic cell 11a can also be any shape such as rectangular, square or circular. In addition, the number of the electrolytic cells 11a can be one. Of course, the number of the electrolytic cells 11a can also be at least two. At this time, the at least two electrolytic cells 11a can be arranged on one testing module 11, and of course, they can also be respectively arranged on at least two testing modules 11. In addition, as a conductor in contact with the electrolyte in the electrolytic cell 11a, the electrode assembly 111 can include a working electrode 112, a counter electrode 113 and a reference electrode 114. Among them, the working electrode 112 can be a glassy carbon electrode, a platinum electrode or a gold electrode, etc.; the counter electrode 113 can be a platinum electrode or a graphite electrode, etc.; the reference electrode 114 can be a silver / silver chloride electrode or a lithium electrode, etc. according to the testing system. In addition, the electrode assembly 111 can be connected to the inner wall surface of the electrolytic cell 11a as introduced below. Of course, in other embodiments, the electrode assembly 111 can also be connected to the outside of the electrolytic cell 11a and extend into the electrolytic cell 11a.

[0067] The liquid transfer mechanism 12 can be used to transfer the electrolyte to be tested and / or the cleaning liquid to replace manual injection of the electrolyte and / or the cleaning liquid into the electrolytic cell 11a by humans. Among them, the liquid transfer mechanism 12 can be only used to inject the electrolyte to be tested into the electrolytic cell 11a, and of course, it can also be only used to inject the cleaning liquid into the electrolytic cell 11a, or it can be used to inject the electrolyte to be tested and the cleaning liquid into the electrolytic cell 11a. In addition, the liquid transfer mechanism 12 can include a transfer component 121 and a suction component 125 as introduced below, and of course, it can also only include the suction component 125.

[0068] Since the electrochemical testing device 10 of the technical solution of this application is provided with the liquid transfer mechanism 12, the electrolyte to be tested and / or the cleaning liquid can be injected into the electrolytic cell 11a through this liquid transfer mechanism 12, thereby realizing automatic injection of the electrolyte to be tested and / or the cleaning liquid into the electrolytic cell 11a to improve the testing efficiency of the electrochemical testing device 10. At the same time, the error caused by manual operation can also be reduced at this time, which is beneficial to improving the accuracy of the testing results of the electrochemical testing device 10.

[0069] Please refer to Figure 1 、 Figure 3 and Figure 4 In an embodiment of the present application, the pipetting mechanism 12 includes a transfer assembly 121 and a suction assembly 125. The transfer assembly 121 is configured to drive the suction assembly 125 to move; the suction assembly 125 is configured to suck the electrolyte to be tested and / or the cleaning liquid, and can be docked with the test module 11 to communicate with the electrolytic cell 11a.

[0070] The transfer assembly 121 can be used to provide power to drive the suction assembly 125 to move, so as to realize the movement of the suction assembly 125 between the position where the electrolyte to be tested and / or the cleaning liquid is placed and the position where the electrolytic cell 11a is located. Among them, the transfer assembly 121 can be the one including the first driving member 122, the second driving member 123 and the third driving member 124 as introduced below, and of course it can also be in the form of a manipulator. In addition, the transfer assembly 121 can be connected and installed on the test module 11, and of course it can also be connected and installed on other objects. The suction assembly 125 can be used to suck the electrolyte to be tested and / or the cleaning liquid, and after being docked with the test module 11, inject the electrolyte to be tested and / or the cleaning liquid into the electrolytic cell 11a. Among them, the suction assembly 125 can be the structural form including a cylinder body 126 and a piston 129 as introduced below, so as to suck the electrolyte to be tested and / or the cleaning liquid by sliding the piston 129. Of course, the suction assembly 125 can also be the structural form including a cylinder body 126, a first connecting pipe 131 and a first liquid pump 133. At this time, the end of the first connecting pipe 131 away from the cylinder body 126 can be directly extended into the container containing the electrolyte to be tested and / or the cleaning liquid, and then the first liquid pump 133 is used to drive the electrolyte to be tested and / or the cleaning liquid to be sucked into the cylinder body 126, and then it can be directly injected into the electrolytic cell 11a through the liquid injection hole 128a of the cylinder body 126 under the action of gravity. Moreover, since the first connecting pipe 131 is convenient to communicate with the container containing the electrolyte to be tested and / or the cleaning liquid at this time, the transfer assembly 121 does not need to be provided.

[0071] In this embodiment, the pipetting mechanism 12 is set to include a transfer assembly 121 and a suction assembly 125, so that the transfer assembly 121 can drive the suction assembly 125 to move, thereby facilitating the docking and communication of the suction assembly 125 with the containers containing the electrolyte to be tested and / or the cleaning liquid (i.e., the carrier container 60 and the liquid storage container 14 as introduced below) and the test module 11 respectively.

[0072] Please refer to Figures 1 to 3, in an embodiment of the present application, the suction assembly 125 includes a cylinder body 126 and a piston 129. The cylinder body 126 is provided with a liquid storage cavity 127a and a liquid injection hole 128a communicating with the liquid storage cavity 127a; the piston 129 is slidably disposed within the liquid storage cavity 127a.

[0073] The cylinder body 126 may extend along the direction of the center line of the liquid injection hole 128a, and the piston 129 may slide along the extending direction of the cylinder body 126. Moreover, on the projection plane perpendicular to the extending direction of the cylinder body 126, the projection of the piston 129 coincides with the projection of the inner side wall of the cylinder body 126. At this time, when the piston 129 slides in the direction away from the liquid injection hole 128a, it can drive the external electrolyte to be measured and / or cleaning liquid to be sucked into the liquid storage cavity 127a. When the piston 129 slides in the direction close to the liquid injection hole 128a, it can drive the liquid in the liquid storage cavity 127a to be injected into the electrolytic cell 11a. Among them, the shape of the cylinder body 126 may be any of a square, a rectangle or a circle, and the shape of the piston 129 may be adapted to the shape of the cylinder body 126. In addition, the suction assembly 125 may include a power member 130 such as a cylinder to drive the piston 129 to slide through the power member 130.

[0074] In this embodiment, the suction assembly 125 is set to include a cylinder body 126 and a piston 129, so that there is no need to provide a pipeline between the suction assembly 125 and the electrolyte to be measured and / or cleaning liquid to be sucked; at the same time, the structures of the cylinder body 126 and the piston 129 themselves are relatively simple, which is conducive to simplifying the structure of the suction assembly 125 and improving the convenience of manufacturing it. Moreover, the volumes of the cylinder body 126 and the piston 129 themselves are relatively small, which is conducive to reducing the space occupation requirements. In addition, using the cylinder body 126 and the piston 129 also facilitates controlling the suction volume of the electrolyte to be measured and / or cleaning liquid.

[0075] Please refer to Figures 1 to 3 , in an embodiment of the present application, the test module 11 is further provided with a liquid inlet 11b communicating with the electrolytic cell 11a. When the suction assembly 125 is in a state of being docked with the test module 11, one end of the cylinder body 126 provided with the liquid injection hole 128a is inserted into the liquid inlet 11b.

[0076] In this embodiment, in the docking state, inserting one end of the cylinder body 126 provided with the liquid injection hole 128a into the liquid inlet 11b can improve the docking stability between the suction assembly 125 and the test module 11. At the same time, it can also improve the sealing performance between the suction assembly 125 and the test module 11, so that the suction assembly 125 can effectively inject the electrolyte to be measured and / or cleaning liquid in the solution cavity 127a into the electrolytic cell 11a. Of course, the present application is not limited to this. In other embodiments, one end of the cylinder body 126 provided with the liquid injection hole 128a may also be directly communicated with the liquid inlet 11b.

[0077] Please refer to Figures 1 to 3 In an embodiment of the present application, the cylinder 126 includes a main body section 127 and a needle section 128. The main body section 127 is provided with a liquid containing cavity 127a; the needle section 128 is connected to one end of the main body section 127, and the needle section 128 is provided with a liquid injection hole 128a. When the suction assembly 125 is in a state of being docked with the test module 11, the needle section 128 is inserted into the liquid inlet 11b.

[0078] The main body section 127 can be used to form the liquid containing cavity 127a, and the needle section 128 can be used to form the liquid injection hole 128a. Therefore, the cross-section of the main body section 127 can be larger than the cross-section of the needle section 128. Among them, in the direction of the center line of the liquid injection hole 128a, the cross-sections of each part of the main body section 127 can be equal; and the cross-sections of each part of the needle section 128 can be equal, or of course, they can also be unequal. That is, in the direction away from the main body section 127, the cross-section of the needle section 128 can be set to decrease to form a conical shape. In addition, the main body section 127 and the needle section 128 can be an integral structure (that is, integrally formed by manufacturing), or of course, they can be separately provided and then assembled by any connection method such as threaded connection.

[0079] In this embodiment, the cylinder 126 is set to include the main body section 127 and the needle section 128, and the needle section 128 with a relatively small cross-section is inserted into the liquid inlet 11b, so that the liquid inlet 11b can be set relatively small to reduce the possibility of foreign objects falling into the electrolytic cell 11a.

[0080] Please refer to Figure 1 and Figure 3 In an embodiment of the present application, the suction assembly 125 further includes a first connecting pipe 131 and a first liquid pump 133. One end of the first connecting pipe 131 communicates with the liquid containing cavity 127a, and the first liquid pump 133 is arranged on the first connecting pipe 131.

[0081] In this embodiment, when the liquid suction assembly 125 is further provided with a first connecting pipe 131 and a first liquid pump 133, since the amount of the electrolyte to be measured is relatively small and the accuracy requirement for the amount is relatively high, the cylinder 126 and the piston 129 introduced above can be used to suck the electrolyte to be tested, while the first connecting pipe 131 and the first liquid pump 133 can be used to suck the cleaning liquid with a relatively large amount and a relatively low accuracy requirement for the amount, thereby improving the applicability of the liquid transfer mechanism 12 to the electrolyte to be tested and the cleaning liquid. At the same time, it also enables the liquid transfer mechanism 12 not to repeatedly move and suck the cleaning liquid, which is beneficial to further improving the testing efficiency of the electrochemical testing device 10. Among them, the first connecting pipe 131 can be a flexible pipe to further improve the convenience of its layout. In addition, in other embodiments, the liquid suction assembly 125 may not include the first connecting pipe 131 and the first liquid pump 133. At this time, the liquid transfer mechanism 12 can drive the cylinder 126 and the piston 129 to suck the electrolyte to be tested during testing and suck the cleaning liquid after testing by the transfer assembly 121. Or, two sets of liquid transfer mechanisms 12 are directly provided to suck the electrolyte to be tested and the cleaning liquid respectively through the two sets of liquid transfer mechanisms 12.

[0082] Please refer to Figure 3 , in an embodiment of the present application, the liquid suction assembly 125 further includes a liquid inlet valve 134, and the liquid inlet valve 134 is provided on the first connecting pipe 131.

[0083] The liquid inlet valve 134 can be an electric control valve or a manual valve to control the connection and disconnection between the first connecting pipe 131 and the cylinder 126.

[0084] In this embodiment, by providing the liquid inlet valve 134, it is convenient to correspondingly control whether the liquid suction assembly 125 sucks the cleaning liquid, that is, when the liquid suction assembly 125 is used to suck the electrolyte to be tested, the first connecting pipe 131 can be closed, thereby reducing the possibility of interference when the liquid suction assembly 125 sucks the electrolyte to be tested and improving the working reliability of the electrochemical testing device 10.

[0085] Please refer to in combination Figure 1 and Figure 3 , in an embodiment of the present application, the electrochemical testing device 10 further includes a liquid storage container 14, and one end of the first connecting pipe 131 far from the liquid chamber 127a communicates with the liquid storage container 14.

[0086] In this embodiment, the cleaning liquid can be stored through the liquid storage container 14, so that there is no need to use other objects to accommodate the cleaning liquid, thereby improving the convenience of using the electrochemical testing device 10. Among them, the liquid storage container 14 can be a container with an opening. Of course, it can also include a container body and a cover covering the opening of the container body. The present application does not limit the structural type and shape of the liquid storage container 14.

[0087] Please refer to Figure 1 and Figure 4 , in an embodiment of the present application, the transfer assembly 121 includes a first driving member 122 and a second driving member 123. The second driving member 123 is connected to the first driving member 122, and the suction assembly 125 is connected to the second driving member 123; the first driving member 122 drives the second driving member 123 to slide in the first direction, and the second driving member 123 drives the suction assembly 125 to slide in the second direction, and the first direction and the second direction intersect; the testing module 11 is also provided with a liquid inlet 11b, and the liquid inlet 11b is located on one side of the testing module 11 in the second direction.

[0088] The first driving member 122 can be a linear module. Of course, it can also be a cylinder. The present application does not limit the structural type of the first driving member 122.
