All iron battery
So, I've started reading about all iron batteries. Apparently they've been around for at least a little while.
Here is what I have gathered so far: Pros: - They are made nearly entirely of iron components. - They are environmentally friendly with no caustic or harmful parts. - No exotic materials. Its mostly iron and water. - Very good cycle life (not sure how good). - Iron is cheap and there is tons of it readily available. - You can make these batteries yourself (though it does not look super easy). Cons: - Low energy density. Each cell puts out about .5V. - They're made of iron so they are heavy. - Low discharge rate. Here are a few videos I've seen. Have you guys heard of this type of battery? It sounds pretty ideal for stationary applications. Who cares if you have a large heavy battery if its cheap, right? Cost has always been the main determinant in dissuading use of battery technology. This appears to possibly fix it. Though, I haven't seen any cost analysis done yet.
