Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a high-conductivity current collector for use in nickel-metal hydride cylindrical batteries. Background Technology

[0002] In nickel-metal hydride cylindrical batteries, efficient current conduction and collection play a crucial role in the overall performance of the battery. As a key component for current conduction inside the battery, the high-conductivity current collector undertakes the important mission of quickly and stably collecting and transmitting the current generated by the electrodes to the external circuit. In early nickel-metal hydride batteries, the traditional current collector could basically meet certain performance requirements.

[0003] During the charging and discharging process of a nickel-metal hydride cylindrical battery, the current collector expands due to internal electrochemical reactions and temperature changes. This expansion worsens the contact between the current collector and the electrodes, resulting in a less tight fit and a significantly reduced contact area. According to the law of resistance, resistance is inversely proportional to the contact area; therefore, the reduction in contact area directly leads to a substantial increase in contact resistance.

[0004] Therefore, this application provides a high-conductivity current collector for use in nickel-metal hydride cylindrical batteries to meet the requirements. Utility Model Content

[0010] As a preferred implementation, the series connection plate is provided with an opening, and the third transmission rod is rotationally connected in the opening of the series connection plate.

[0011] The beneficial effect of the further scheme is that the opening is provided on the series connection plate to facilitate the connection of the third transmission rod, the copper wire connected to the series connection plate is installed and placed on the third transmission rod, so that the copper wire can be raised upward when it is squeezed during use.

[0014] As a preferred implementation, the transmission plate is provided with an inclined groove, and the sliding shaft is fixedly connected to the series connection rod and slidably connected to the inclined groove of the transmission plate.

[0015] The beneficial effect of the further scheme is that the inclined groove is provided on the transmission plate, and when the sliding shaft slides in the inclined groove of the transmission plate during use, the series connection rod can be driven to slide to the side close to the series connection plate to squeeze the copper wire.

[0016] As a preferred implementation, the first fixed sheet is fixedly connected to the side of the shell close to the power inlet, and the second fixed sheet is fixedly connected to the side of the shell close to the power outlet.

[0022] Compared with the prior art, the utility model has the advantages and positive effects that:

[0023] In the utility model, the second fixed sheet near the series connection plate is heated and slightly expanded due to the heat conduction of the series connection plate during the continuous conduction of the copper wire. The expanded second fixed sheet extrudes the elastic sheet connected thereto, and the elastic sheet is slightly displaced under force. The displacement is transmitted to the series connection rod, so that the series connection rod is moved downward. The sliding shaft fixed on the series connection rod slides in the inclined groove of the transmission plate. Due to the guiding effect of the inclined groove, the series connection rod slides to the side close to the series connection plate while moving downward, so as to extrude the copper wire. When the copper wire is extruded, the copper wire is tilted on the third transmission rod due to the sliding connection with the third transmission rod and the rotational connection relationship of the third transmission rod at the opening of the series connection plate. The tilting of the copper wire drives the second transmission rod fixedly connected thereto to move upward slightly, and further drives the first transmission rod to move, so that the power inlet and the power outlet fixedly connected with the first transmission rod are slightly moved upward, so that the power inlet and the power cable and the power outlet and the output cable are more closely connected. The whole transmission process utilizes the initial power generated by thermal expansion to convert the slight thermal expansion into a close adjustment action on the electrical connection part, effectively compensates for the poor contact problem caused by the possible expansion of the current collecting plate, and ensures the stability and efficiency of current conduction.
