How long is vanadium battery life?

Source: 2020 - 03 - 29 clicks, vanadium battery service life is long on the market of lithium ion battery life of about 1000 to 5000 times. Lithium ion battery energy storage principle of the main is lithium ion on the solid electrode embedding and remove. Lithium ions repeatedly extract ( Error) Cause the stress variation in the electrode data, resulting in crack failure. However, vanadium battery charging and discharging mechanism is one of the valence state of correction, is a completely reversible process. Considering the life of the remainder of the system, in more than half a century to do this is completely possible. In your substation, you save a lot of maintenance costs. Even compared with other mobile battery, vanadium battery durability is also impressive. In the liquid flow between the positive and negative of the battery with a layer of ion exchange membrane is separated, in order to avoid the positive and negative of electrolyte mixed cause cross contamination. But now even the best Nafion membrane is not sealed, as time goes on, some ion will permeate to the other side. The positive ions in the asymmetric flow battery, cannot be involved in the cathode electrode reaction, led to the decrease of the capacity of slow, until the original size reduced by half. But for vanadium battery, the cathode is negative electrolyte composition is the same, no matter you zha penetration, anyway I to recharge my batteries ╮ ( ╯▽╰) ╭ when need long-term storage, empty in the heap of electrolyte, in order to prevent the negative electrolyte contact. Therefore, the vanadium battery self-discharge rate is relatively low, storage time can range from a few hours to a few days.
