When I left the Iron Redox Flow Battery overnight connected to the AA battery, and switched on the pumps again in the morning, I immediately noticed brown liquid flowing through the pipe into the tank, so I asked AI what happened (novice here too !!😇), then I had to understand how exactly a battery works. So buck up, now we are going into depths of battery science, but first the basic- Current is how many electrons can you push in the circuit per second, voltage is how hard you can push them, current density is how many electrons can pass through battery electrode per unit area per second. The higher the current density; faster the battery charges, lower the current density; slower the battery charges. But remember, per unit area, so the total amount of current flowing in the battery is dependent on area of the electrode also. A good battery crams as many electrons possible as quickly as possible in a unit area of the electrode. For instance, when you connect a fast/turbo charger to y...

So, when looking for a cheaper alternative to Vanadium batteries, I stumbled upon all iron chemistry,  the absolute cheapest battery chemistry possible, using only iron, the most mined element from Earth's crust. The metal so cheap that its literally the basis of human civilization. No need to heat the battery, no need to check supply chains, Iron is so abundant that you can find it wherever humans are. I was convinced, Gemini gave me the broke college kid solution. So I ordered Iron chloride from the internet, you know how much lab grade 500g highest purity cost me ? Rs 800 ($8), that's pennies as compared to Vanadium. So before I give you step by step procedure of building you own Iron Redox Flow Battery we need to understand how it works. Working of Iron Redox Flow Battery Similar to Vanadium, Iron redox flow battery has iron on both sides, on both sides it is in Fe2+ state, when it charges on the positive side it converts Fe2+ to Fe3+ (loses 1 electron) and on the negative ...
