Description

technical field [0001] The invention relates to a terminal electrode and a manufacturing method thereof, in particular to a terminal electrode device and a manufacturing method for a liquid flow battery, belonging to the field of liquid flow batteries. Background technique [0002] In the prior art, compared with the unipolar structure battery, the bipolar structure battery has smaller volume and weight, so it has higher volume specific energy and mass specific energy. At the same time, the bipolar structure battery has lower production costs, and the battery structural components are recyclable, can work at room temperature, and have excellent charge and discharge characteristics. [0003] However, the dimensional stability of the terminal plate of the traditional bipolar battery is poor, the voltage efficiency and energy efficiency of the battery are low, and the service life of the battery is short. Moreover, the traditional terminal electrode plate is relatively thin, a...
