How long should one last? Why do you think adding alum salt seems to stop any galvanic action on the cell? Why does their power output vary with temperature? I only ask because you seem to know a lot about batteries..

Lol, just found that my cement is water proof, will try to force it. Thanks, I will let you know
.Lol interesting question. what is being wasted .

You ask very good questions: (a) These kinds of "dry electrolyte" cells are inefficient because of their high internal resistance. The "dry" matrix which supports the slowed chemical reactions produces a performance "trade-off." In exchange for a very long life efficiency is sacrificed. (b) It is hard to know how long one of these cells could last. Possibly quite a long time. Eventually, the metals in the two electrodes will deteriorate and the cell will expire. Generally, the more active metal (the negative electrode) is consumed as the cell is used. (c) Adding the alum may prevent excessive "galvanic action" which would consume the electrodes when the battery isn't being used to provide power to a load. Choosing (or discovering) an electrolyte mix which has just the right pH to produce good galvanic action for long battery life is always a challenge. (d) Semiconductor materials and certain chemical reactions work best when heated. Batteries in general tend to perform poorly when too cold. In the case of the dry electrolyte cells there is a more pronounced sensitivity to warmth; they will work better when warmed. These kinds of cells are best suited for use in very remote locations where a little power is needed for some purpose for a very long (months or years) time. Until someone has actually monitored such a cell's performance to find its useful lifetime we'll not know with any certainty. The high internal resistance of the cell which limits the amount of current which can be drawn without reducing the cell voltage too much. To achieve any sort of useful efficiency this cell must power a relatively high resistance load (several times greater than the cell's internal resistance.) Has anyone yet measured the internal resistance of one of these cells? It's a fairly easy procedure. |

@seamonkey you bring up some interesting points, and when my batch of alum salts comes i'll make some zinc copper borax and paper towel batteries (keeping them in humid in their own bottles): one without alum, two with. The two with, i'll keep at different temperatures ( one alum and one non alum in fridge ) the other outside fridge
if i can get them to run a solar garden light led at all same brightness using potentiometers, the long term outcome should prove informative.

You think nimh less efficient than nicd, Seamonkey? Crystal battery work by corrosion?
btw, I dont have can yet but when I mix diluted alum I have to portland cement, for other experiment, I smell urine.... |

a good choice for certain applications. It does have a tendency to develop "short circuits" in cells due to dendrites and must be periodically "blasted" with a high current pulse to clear them out. I find the NiMH to be better for my uses which aren't too demanding. They're less likely to develop shorted cells and have a higher capacity for a given cell size. The NiCd is probably a bit more efficient than the NiMH for most users. Yes, the "crystal battery" does work by a chemical action which is similar to corrosion. Quote:

Thanks for the info. You disagree with bedini then?
I hear hiss when I pour it. It seems the NH3 is released. |

I do disagree with Bedini on some things. I'm not familiar with his beliefs regarding these solid electrolyte batteries though. Can you elaborate? |

Thanks Sucahyo for the links and quotes to
Bedini's thoughts on the matter. No, I don't fully agree with Bedini's speculations and conclusions; I believe it is simple electro-chemistry. De-polarizers are a necessity for most primary cell chemistries to remove the hydrogen which is generated at the positive electrode. Unless the hydrogen is removed (by recombination with oxygen to form water) it will interfere with the current flow and cause current to drop off to a very small quantity until the hydrogen dissipates. Copper Oxide will work as a de-polarizer in these solid cells. In fact, copper oxide is used as an oxidizer in certain explosive mixtures. There are some primary cell chemistries which work differently but in those cases the power produced in the cells is very slight. They're used mainly for laboratory voltage reference cells and are not really intended to power any load. The solid electrolyte cells are fun to play with and will indeed seem to be almost "magical" in how they function. But, in order to produce significant quantities of voltage and current (power) the more conventional cells must be used. It is very easy to make "wet cells" with aluminum foil and carbon rods (from old flashlight cells) which can easily power a transistor radio in an emergency situation. Several cells must be series connected to get the 6 or more volts needed by the radio or other device. |

Thanks Seamonkey. Agree that crystal battery has very little power.
My battery latest condition: - 1.25V open - >>0.5mA at 0.95V. |

Update. Since I don't have something to deplete the crystal battery, I just attach my analog amp meter which kept indicating more than 0.5 mili Amp. However the voltage now drop from previous 0.95 volts to 0.5 volts. Let see if it can drop to zero volts tomorrow.

You're giving it a good test to see how well it performs
with a continuous "heavy" loading. If you disconnect your "load" for several hours to let the solid cell "rest" it should "recover" to some extent and be able to deliver the load current at the higher voltage first observed for a time. But, it will drop off as you've already observed. It will indeed be interesting to see how long it will function! |

Yes.
I try detaching load not in hours but in seconds: Youtube - Crystal battery metering, bouncing volts After overnight it show 0.3 mili amps and 0.3 volts. When the amp meter is detached for some seconds, the voltage rise quickly to 0.7Volts and when attached again the amp start at 0.5 miliamp then steadily drop to 0.3 mili amp. |

Just sharing a quote from john bedini because i agree and believe this is where the power may be coming from in these batteries.

Thanks Ben, that is interesting.
About material, Bedini suggest us to heat the copper until it goes black to get CuO. I wonder why we cannot use charger? If we use electrolysis CuO should form if we apply positive voltage to copper. I also wonder how crystal form in nature. If it is because of electricity then applying high voltage but without touching the electrode may be a good way to rectify the alum crystal while drying up. Second day of loading, 0.23 mili Amp, 0.194 volts. |

Good question.
Many metallic oxides and sulfides are used in various pyrotechnic mixtures. In fireworks the naturally produced compounds always produce the very best effect. It seems that certain compounds which are produced by natural means (heat, fire and burning) are more energetic. Those same compounds which are synthesized by chemical reaction or electrolytic reaction, although chemically identical in "formula" just do not work the same in fireworks. It's one of those things which doesn't seem to make any sense to chemists and scientists. Perhaps in the case of the solid electrolyte cell the manner in which the copper oxide is produced is most important? |

Thank you. I am not talking about the effect of any energy that you mention. I think the strength is small, but may have strong influence on correct place.
Some sign you should watch for: - temperature feel hot even when thermometer indicate same value, mentioned not by you. - more frequent nightmare or restless night or hard to sleep - high temper inside the house - no birds chirp anymore - cloudy all day long but no rain - foggy sky but clear ground I am not talking about spiritual effect here. Not ghost or psychic event, but I think it is the same thing Bedini mention can be produced by his ferris wheel, by geometry. If you already experiencing the above even before creating crystal battery, then it can be worse. I already mention the solution before. I mention this because I think this can influence your miss health. It influence my miss. If your crystal battery do not produce effect as I mention above then I am relieve. On experiment, guess what I did to my crystal battery , mute it on play, I forgot to turn off mic:Youtube - Crystal battery - increased voltage with load The battery voltage drop from 0.440V to 0.164V when loaded with amp meter but then steadily rise its current and voltage, now at 0.25mili Amp and 0.236V, beginning at 0.15 mili Amp and 0.164V. Look like the battery gaining charge with load, and now the same battery has double output current . Can you guess what I did to the battery ?
