I'm sure Exide has some unpublished trade secrets that they aquired with the purchase of Edison's technology, but do not fear - there is plenty we know about Edison's work that is not buried in the "Exide vaults".
Before I go too much further, since I haven't taken the opportunity to say this yet on this forum, if all you are looking for is a simple storage media for your power needs that takes minimal attention then use LA or some other battery technology other than Ni-Fe. But, since this IS a Ni-Fe thread, if you are ready and willing to work it, understand it, and (yes) maintain it then Ni-Fe can be the right choice. I do not believe there is no "one size fits all" solution out there. The right choice depends on your individual needs and situation.
If you really want to learn about Ni-Fe technology, here's a listing of the majority of Edison's Patents dealing with his battery initiatives including electroplating, etc that you can start with. You need those references too if you want to truly understand his battery construction and the limits of his technology as it was constructed when he was alive. The "good stuff" starts in 1901, but I give you a couple other references where Edison was working with Pb, Cu, and Zn. Please keep in mind these are the Edison references only, and the information inside them certainly in no way makes you an expert in the application of Nickel Iron redox chemistry for power storage (even if you believe you understand it throroughly). It is the beginning of a journey, not the end. Keep researching, get your hands on some cells and learn for yourself lest you be lead astray by self proclaimed experts, vendors, etc. There has been lots more knowlege accumulated since 1927. Don't limit yourself to the century old information.
