Battery (battery pack) Nickel Zinc to 1.6V better than NiMh?

[chatelot16]

anyway, all the electrodes will be sintered nickel except that the + are chemically filled with nickel oxide and the least zinc

my hypothesis of exes of zinc at some place of the plate is perhaps not the good, there is another one: dentrite of zinc entangled in the separator which deconectent plates during the discharge, thus which will not be dissuaded never in the electrolyte, and will be reconnected to the next charge and will grow further

another solution to try, an additional nickel grid between the plates + and -, at the beginning of the discharge we try to unload using this grid as less electrode: it will eat all the priority zinc all over and clean zinc that would contaminate the separator ... again an idea that will not be patented, since disclosed today

but before making too much elucubration it will be necessary to find traces of history of this battery drumm train, of those who made the maintenance

Interesting idea possible.
It remains patentable, because I doubt that the IPN reads econology in the publications of anteriority !!!
Moreover, there remains a huge development that will be patentable if it works.
Another problem, for small batteries, it is necessary that the system is simple and this idea requires a computer management with semiconductors of control, used on Li ions.

I think that buy SuperGenix in the US who still have the problems of short juice seen the opinion on amazon US!
http://www.amazon.com/s/ref=nb_sb_noss? ... x&x=9&y=11
and disassemble them after their death should help identify the problem.
But the problem must be difficult to solve since the 1931 years.
It should be known how drumm had tinkered a solution for his train to walk a decade (secret ??)
The only information is that on the article on Nature in 1931)
Having grown very different organic crystals, on the same system, one can have normal cubic crystals, and ultrafine whiskers and long as needles especially in fast growing conditions!
A big crystal believes in the shelter of whiskers often !!
One solution is that the whisker encounters a wall that blocks its elongation, but then it may grow in the pores of a semipermeable wall.
One solution may be as for the Daniell stack, a long path between the + and - plates, or a container geometry where the dendrites grow in an opposite direction ???
But the dendrites follow the electric field.

no matter, if someone files a patent, he will pay anuity for nothing! if I want to manufacture I show the forum econology (and some other) as proof of anteriority and it is classified!

Ben reviews on Amazon are pretty good, not to say laudatory ... except one that also gives an indication of the capacity of the batteries powergenix:

Do not be fooled into buying these batteries for a newer digital camera. All new digital cameras that use AA batteries are designed for 1.2V NiMh batteries. PowerGenix has made the most of these high capacity batteries. These AA batteries are rated at 2500mWH, not mAH. What does it mean to you, it's only 1563mAH, which is half the capacity of the best NiMH. Even low self-discharge NiMH batteries, such as Eneloop, with modest capacities of 2000 to 2400mAH are higher than these. If you convert the highest capacity 3100mAH NiMH AA battery specs to match these NiZn ones, you get a whopping 3720mWH. That's 38% higher capacity which translates to more pictures. Add in the fact that these batteries can not be charged in 15 minutes like NiMH batteris can and you can see they are not worth the money. If you need the extra voltage, Rechargeable Alkaline batteries may be a better alternative because they offer 25% more capacity than NiZn batteries.

So, unless you have had a new light, it was made before NiMH batteries became common, it just does not make any sense to buy these batteries. They are all smoke and mirrors.

The guy has all the same gutted in his reasoning.

2500 mWh ca gives well 1562 mAh under 1.6 but it is not equivalent to 1562 mAh under 1.2 V.

Under 1.2 to have 2500 mWh you need 2083 mAh. So it's better than the 1 / 2 of his reasoning.

for my personal use the powergenix does not interfere much with me: the NiMh month dear in the supermarket of the corner is enough for me ... it is first the super charger that I must manufacture

buy some powergenix to dismount one and try the others will be interresting

the big advantage is the low price of zinc, but it is ridiculous for small accu: if I wanted to make them in France, it will be more expensive than the current NiHh

for the electric vehicles it is another thing: it is of the big volume and the price of the materials is the principal one, the absence of danger of explosion or pollution makes it possible to foresee a dismountable construction repairable:

the sintered nickel seems to be practically unalterable, if the nickel oxide in the electrode is more damaged it must be possible to regenerate it chemically

non-corosive caustic potash for nickel and iron allows a fully screwed construction everything will be easily reparable ... we will not be afraid of the life of the battery, but only to have to change some piece

it will also need a charging system that monitors each element separately to isolate the defective without all fail

the NiMh month in the local supermarket are enough for me ...

For info: have you already compared the prices compared to those of econoshop?

[chatelot16]

for the conversion wh Ah any depand of the characteristic of what consomme: if it is a diet with linear regulator, there is only the current which counts, the supplement of tension can possibly serve to walk to the end, but will mainly serve to heat the regulator: this is the case of all low consumption appliances, remote control, small gadget

if the device has a decoupage power supply, the higher voltage must reduce the current and it is the energy in Wh that counts

Another note on self-discharge: receive a new battery well charged does not mean low self-discharge: it is possible that the new battery has a passivation system that avoids self-charging as long as it is not used, but disappears the first use ... I do not know the detail but it is a ca ca for lead batteries that can stay long enough without suffering at the seller, and no longer care to remain unused after the implementation. service

no matter, if someone files a patent, he will pay anuity for nothing! if I want to manufacture I show the forum econology (and some other) as proof of anteriority and it is classified!

So to sink the future patents, there is only to let off steam on econology of all ideas, crazy, twisted or delusional possible, such as Okofen stove or other brand, managed in fuzzy logic or whisker scraper in the Nini Zn !!!

So there is only phosphor !!

[chatelot16]

exactly! to make a patent impossible, it is necessary to publish, it is the reason of a lot of shema electronics in certain magazine, one does not see the interest, the interest is only to leave a trace even if it 'interresse persone

Atention to serve as anteriority it is not enough to write any chariabia meaning anything and the opposite: it needs a description of the idea that stands, but no need for proof that it works

it's not just a benefit, it's also a big problem! the one who seeks advice to develop a good idea in the intension of patenting has quickly done looking for help to say enough to ruin any possibility of patent: that is why some prefer to file 36 patent not even sure it works, to be sure that what will be divulged during the development will not ruin the patent

the multitude of foolish patents is also a way to drown the fish and the competitor who tries to read everything will not find in which is the good idea!

the NiMh month in the local supermarket are enough for me ...

For info: have you already compared the prices compared to those of econoshop?

AA NiMh casino giant 9.9euro 4 ... same price for 4 AAA ... note this department is often empty and it remains only energizer or other brands much more expensive than econology

of course it is not a low self-discharge, and I use them in any way and do not realize how long they live

for the telecomande and the clock I put only alkaline which lasts several years, whereas with NiMh it is necessary to change too often

another problem with some gadget low price that may be forgotten in a corner, I prefer stack, rather than risk forgetting the battery

for the device has very low consumption charge alkaline battery is perhaps the best solution, but the tests are so slow, that I dare not say that it works for several years

do not forget the real best solution, replace the batteries with a mains supply! I am always horrified when I see 220v electric heating thermostat or battery programmers!
