    Cool NO Dissasemble Enloop gizzard pics

    There are low bandwidth pictures in this thread, if you dont see them, then the server that serves them is messed up, generally this only lasts for a while, but if it isnt working , i myself wouldnt know and you will.

    I had cut the nipple off a enloop....

    and it revealed this rubber (type) cap thing inside...

    and what looked like a vent hole
    so i poked a non conductive thing in there, to see if there was another seal, and bumbed into somthing, Intrigued ...

    i bandsawed the top off (wearing face shield)

    this revealed a soft plastic blue insulator with hole in it


    i used a nail as a pick and lifted up this soft insulator thing
    and now i could see the electrolyte roll

    well the cell is this far apart now, , , so i slice it down the sides

    then i bent one side down
    this picture was supposed to show one layer set of the roll from the side
    but i am not sure it shows all layers

    and then i could see the bottom soft plastic blue insulator

    as you can see i did cut part of the roll, which is showing on the bottom side in the pic

    see the can has no texture, although it might have looked that way

    so then i figured, you would want to see how this all stacks or layers up
    so before it came to pieces, i shot this picture, which shows the layers in position


    then i rolled it out, remember a bit of it was cut off and is still in the other half shell.
    dont be FOOLED, the dark grey is BLACK its carbon type black
    the picture is just light up highly.

    the top cap (anode i guess) is connected with 2 short metal bands
    to both sides of the crumbley black layer


    then i tore each piece, to attempt to understand its properties
    one has about 4 layers, tore like wet paper
    one has 1 layer tore like wet paper
    and on the right center, that crumbled
    the bottom right mesh thing is metalic

    this was taken before i tore it obviously, it has all the pieces laid out
    they are not nessiarily in "layered order", only the rolled out pic would show that.


    if you need to see anything else, tell me quick, cause somebody just opened the garage and drove over the top of it

    What i Lernt:

    1) it can vent without bursting like some cheap cells

    2) the crumbley anode connecting piece, means dropping this , damaging it, just like other rechargables will damage its capability fairly quickly

    3) Shocking it with extreme input or output powers, and flash amping it, and shorting it out, wont just heat something, but could change the properties around the anode connect, ruining its ability to deliver high power.

    4) expansion and contraction of the body via pressure or heat and cold, could induce (lets call them) inpurities into the cell in tiny ammounts, it is unlikly to change its properties much.

    5) crunching the top (same as damage) could effect the seal, and on the bottom there is very little gap between the electrolyte roll, and the base of the can, so avoid Jamming the bottom in, although there IS a gap on the bottom.

    6) improper soldering or welding would also be occuring very close to the important parts of the cell, and would want to be done quckly or carefully

    7) yes there IS a gap or hole down the center where there is nothing, its small but it exists.

    Nice? pics.. It's interesting to look at but at the same time sickening...
    Did you burn it or something?! Poor eneloop, thanks for sacrificing the cell.

    I clipped the nipple to see if it could be "shortened" and ruined it immediatally there. so i figured, might as well Finish the job.

    Good info there, I'll remember not to drop the cell so it won't land on the anode side.

    Do you think if high current discharge such as 2A-5A would damage the anode thingy? Some 15min chargers charge at AMAZING huge amount of current. I am wondering if the currrent will burn the anode thingy.

    i dont know, other cells which i have dissasembled the connections go to more materials or direct to METAL plates not crumbley things ???
    i would think that anything the cells is speced to be able to do, it will and can do.

    i would JUST warn against Shorting and "FlashAmping" to see what it is "capable" of. i couldnt guess how many amps it would take,,, hmmmm :-) unless BRB.

    ok there is the connection i was refering to.

    i think really that is all you need to see or know, just what your dealing with internally in the cell
    my tests dont end up being able to tell enough


    and the close up of it. you can see that MY shorting of the battery during dissasembly even altered the properties there.


    so i take this sofisticated lab test device
    sombody came over to check out what i was doing


    and hook it up to the lab power supply (good for only 3amps)
    the resistance of it doesnt budge when i change the amps across it
    that shows it should be able to handle 2X this

    this picture ^ also shows the Backside of the connection, and the insulator that was over it on that side, its flapped up now.



    running out of sofisticated test equiptment, it was time for the big Dawg
    a 10amp car charger , some 120Watt of juce for a single spark did that

    a longer spark and the insulator caught fire, and the connector came completly off and was Red hot metal.
    note the leads usually get soggy themselves when 10 amps is going to the car, the leads didnt budge before this was popped

    conclusion , somewhere between 6 and 50 amps :-)
    but as you can see a Short of itself does alter it a bit, but it was still ok connected.

    Hello VidPro,

    Excellent information.

    I wonder if the Hybrid is built the same way... ?

    me too i wonder a lot of stuff, like if high caps would have a longer thinner rolls, and less gap in the center, and a bunch of other stuff.

    this metal mesh thing looks totally similar to the power supreme D cell, when it ejected its parts out onto the floor violently. also i dont remember a second metal plate in it either.

    GREAT information and photos, VidPro. Thanks! Based on what I've seen, I'd like to see a video of those cells being manufactured someday. Maybe I'll send a request off to The Science Channel. Or Dirty Jobs.

    For sure great information VidPro!

    Are you planning any sort of ceremony for when you bury the poor Eneloop that gave up it's life for our enlightenment?

    Excellent job, VidPro !


    We've all learned a lot from your "autopsy" photos & descriptions.



    But the REAL question is:

    "How well did it work once you put it all back together ?"

    Did you notice any significant reduction in capacity after reassembling the Eneloop?

    I concur. He was spinning an Eneweb. See it in the lower right-hand corner of the photo. Appears to be an hybrid type of web - longer lasting and more powerful than the regular one.

    i donno you tell me, here is the dictionary version

    anode (ŕn´od´) noun
    Abbr. a.
    1. A positively charged electrode, as of an electrolytic cell, a storage battery, or an electron tube.
    2. The negatively charged terminal of a primary cell or of a storage battery that is supplying current.
    [Greek anodos, a way up : ana-, ana- + hodos, way.]

    wow does it get any more confusing that that? so we revert back to the origin of the word, "a Way UP" or the way OUT :-)
    next time i will refer to it as the terminal .

    I'm still confused!

    The first quote is what sparked my question - were (are?) you saying that dropping it, regardless of whether the positive or negative terminal was impacted, is a bad thing?

    Thanks!

    dropping cells (hard) has always been a bad thing, i have ruined rechargables that way before.
    after i dissasemble i see that the black sheet thing there that is connected to the top terminal, is very crumbley, and the connection area is not so big.
    so that sorta explained WHY dropping them hard, and shorting the terminals was ruining them.
    they are much more fragile internally than i suspected, even though they are tightly rolled together.

    Very interesting. Thank you.

    I wonder if alkalines have similar fragile connections?
