Description

Technical Field

[0001] The utility model relates to the technical field of vanadium battery repair, in particular to a positive electrode sheet of a vanadium battery and a vanadium battery. Background Art

[0002] Vanadium battery, whose full name is all-vanadium redox flow battery, is an advanced liquid flow battery technology that relies on the redox reaction of metallic vanadium to store and release electrical energy. Vanadium battery stores energy by converting vanadium ions between different oxidation states. When charging, the valence state of vanadium ions changes; when discharging, chemical energy is converted into electrical energy. Vanadium battery is suitable for large-scale energy storage, such as wind energy, solar energy storage, as well as grid peak regulation, backup power supply, etc. Vanadium battery consists of positive and negative electrodes, liquid storage tanks, diaphragms, bipolar plates and pumps. During the use of vanadium battery, when the temperature of the positive electrode liquid inside the vanadium battery is higher than 45 degrees Celsius, pentavalent vanadium is prone to precipitate vanadium pentoxide. These precipitates will block the flow channel, causing the performance of the battery stack to deteriorate and may damage the positive electrode. At this time, staff are required to inspect the positive electrode in time;

[0003] However, when existing staff members inspect and repair the positive electrode sheets of vanadium batteries, it is inconvenient to remove them because the positive electrode sheets of vanadium batteries are heavy, and the electrolyte is corrosive to a certain extent. The positive electrode sheets of vanadium batteries are immersed in the electrolyte, so when the staff members remove the positive electrode sheets of vanadium batteries, the electrolyte adsorbed on the outside of the positive electrode sheets of vanadium batteries can easily get on the staff members' limbs, which has a certain impact on the safety of the staff members. Therefore, the existing needs are not met. In this regard, we propose a positive electrode sheet of a vanadium battery and a vanadium battery. Utility Model Content
