Vanadium battery compared to other battery safety?

Source: 2020 - 03 - : 29 and click traffic safety as mentioned earlier, lithium-ion battery pack need an unordered battery processing system, in order to avoid overcharge, over discharge and overheating. Overcharge and large current will lead to failure and scrap, electrode data cell expansion and leak, lithium or short circuit. Data and the carbon in the carbonate battery electrolyte is flammable, such as leakage is easy to cause fire explosion. But vanadium battery in the use of reversible chemical change of vanadium ion in aqueous solution, its function has nothing to do with the electrode structure, so even in large power flow is also very flexible. In addition, overcharge will only lead to electrolysis of water, so there is no question of hydrogen in time. As for the fire water solution do you think will catch fire? ╮( ╯_╰) ╭ if there are any security hidden danger, that is the acidic electrolyte. Vanadium battery electrolyte containing the more concentrated sulfuric acid ( 2 - 3mol/L) , to improve the solubility and water of the pentavalent vanadium oxygen evolution potential, while pentavalent vanadium must be poisonous. However, considering the entire life cycle, vanadium battery in the environmental protection still has some advantages than lead-acid batteries. Where have armor, there are weaknesses. Downside of vanadium battery energy density is low, only 15 40 wh/L, and even is lower than lead acid batteries, lead to equipment big volume, heavy weight, difficult to applied to the mobile power supply. Vanadium salt molecular weight is large, limited solubility in water. Market electrolyte usually is 1. 5 ~ 2 mol/L vanadium solution, at present the international record for 3 mol/L. A: I'm the project at hand is to refresh the number, I am very sorry to do so little work. After 30 years development, the function of vanadium battery is close to the ceiling, the other electrochemical system also in the test. In the meantime, more complex business skills including sodium - 多 Sulfur flow batteries, zinc bromide pappy flow battery ( Zinc anode metal electrode) Battery energy density, flow to record any zinc - polyiodide ( 167 wh / L) Energy density, and organic systems record the lithium sulfur batteries ( Lithium sulfur semi-solid) Semi-solid liquid flow. Other systems do not open it.
