| -see the docs from the manufacturer's of the modern batteries seems like efficiency is reasonably high actually, was not able to determine if the charging efficiency is nearly equal to the round trip efficiency, so the graphs might paint an overly rosy picture, but I think it is pretty close

The present state-of-art advantages, limitations, and uses of the nickel/iron battery, along with its electrochemical characteristics, are outlined in this review.

| all things considered there seem to be very few patents related to nickel iron batteries, but a lot more on nickel zinc for some reason, also this searching through patentsonline did not unearth the edison patents so there is room for improvement in the search method. Also the swedishand german patents should be retireved and translated though I assume they would be in swedish or german so I did not do that. There are probably more edison patents to be uncovered.

|
| Clearly a chemist or someone else with significant expertise is needed here to work out the details. For example sulfur from vulcanized rubber can contaminate the battery chemistry apparently. IIRC steel has a small quantities of sulfur in it so using sheet metal as the anode might not work out although that of course remains to be determined....

| In many cases docs were focussed on weight and discharge rate, but that is not out main concern, mainly $ per kWh and cycle life, with a discharge rate of at least 0.3 C (i.e. 300 watts for a 1kWh batt) it would work okay for pure solar systems, for biomass a higher discharge woudl be nice as it's primary function is to level the load on an hourly and daily basis at relatively high powers so a higher discharge rate could allow a smaller battery (whereas with pure solar you need a battery big enough to last for 3 days anyway and therefor even if the discharge rate as a fraction of capacity is low that is not a problem since the battery is so big anyway). However because batteries wear out partly as a function of the energy dumped into/removed (also ambient temperature but this will vary depending on the precise details of the battery, on ironedison.com it indicates substantial loss from elevated temperatures but the precise reaction that causes this needs to be identified) from them they may be considered on both a capital cost and running cost basis. Higher discharge rates will not in themselves affect the running cost, only capital cost, which may or may not be relatively small, that would need to be considered before effort is expended to produce a battery that would be okay with higher discharge rates. Secondly, there are no hard and fast rules on discharge rate for a given battery except to prevent overheating and achieve good energy efficiency, or for unusual reasons which are chemistry specific. The rules of thumb listed in battery datasheets are computed based on thermal characteristics, internal resistance of the battery (the higher it is the lower the discharge/charge rate you woudl want because Ohms law applies, therefore higher currents result in higher resistive losses) and in some cases unusual battery chemistry details like high speed charging resulting in wierd crystal structures of the anode or dendrite growth. Usually a battery can be operated above the rated charge/discharge rate as an engineering compromise though, which should be kept i nmind

|
| In an OSE context it may no longer make sense to talk about battery cycle life in the same way. In a consumer context when a battery goes dead you get a new one, in some cases paying to get rid of th old one. And yet the active materials have not dissapeared. However there are sometimes irreversible side reactions that occur, changes in chemistry, the electrode that was supposed dto provide mechanical sterngth etc has dessolved, etc. For lead acid batteries there is information available on this of course. What is it for nickel iron? There is a whole industry based on rejuvenating "dead" lead acid batteris though clever chemisttry techniwues etc. and perhaps analogous techniques shoudl be worked out for nickel iron as part of this project. That could help to substantially decreae the effective running cost fo the batteries. There may already be a lot of information in existence to be drawn upon as these batteries have be used since they were invented in niche markets such as european mining, and in China, rather than as it is portrayed as beign forgotten.
| | ===Collaboration=== |
|
| |
|
| By the way from what I have read this stuff about batteries lasting 50 years that some manufacturer's claim either includes this maintenance or it is bunk. They may last 3, 4 or 5 times as long as lead acid but certainly not 50 years of daily use without some kind of serious maintenance.

Then 150 lb of nickel would be $600 for baseline cost at scrap nickel prices. Except the process relies on Nickel Oxide Hydroxide - not the same thing. So we need to trace the manufacturing process down to nickel oxide hydroxide sourcing. As well as how much nickel oxide hydroxide is actually used per battery. |

Also it is yet another component to add to the system and synthesize which is bad for OSE, how common is lithium in the environment?. | | Here is a list of the document titles, and other information from the last intact copy of the page I had built for the nickel iron project before it was torn up, for more information [http://opensourceecology.org/w/index.php?title=Nickel-Iron_Battery&diff=prev&oldid=32539#library search the titles on google scholar]. |

| There area many patents on the nickel electrode geometries and how to make them ususally intended for nimh or nickle zinc but coudl be used for us too, though again the perforated pockets are porbbaly adequate for our purposes anyway, they are usually intended to solve problems like low energy density etc which is not amajor problem for us anyway(
