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

[chatelot16]

hello, new topic for a new battery which we are starting to talk about
https://www.econologie.com/forums/piles-jeta ... 10144.html

Ayé I found it is Nickel Zinc (AA NiZn) and it is even in 1.6V:

No idea if it's distributed in Europe.

* Highest Performance for high-drain applications
* Environmentally friendly and 100% recyclable
* 1.6 VoHs- equal to an alkaline battery
* Higher power (30% higher voltage than NiMH)
*We recommend PowerGenix Chargers

PowerGenix NiZn AA batteries are more powerful than NiMH and NiCD (1.6V for NiZn vs. 1.2V for other rechargeable). NiZn is also environmentally safe, unlike throwaway alkaline. Every part of this battery is recyclable, from the interior components to the packaging it comes in.

NiZn technology is perfectly suited for high-tech devices like MP3 players, digital cameras, toys, and LED lights.

PowerGenix NiZn batteries must be charged using a NiZn charger: we recommend the PowerGenix Quick 1-1.5 Hr. Charger.

I think I just found out why we don't find these batteries in France, it's a patent PB:
http://www.lexpansion.com/economie/cett ... 22090.html

http://scps.fr/

It would mean that we already find nickel zinc batteries manufactured according to a French patent, and that the French who filed the patent does not sell anything!

the principle nickel zinc seems simple enough, only defect the zinc is redisposed anyway and makes short circuits after a low number of cycles: it does not seem to me a big problem for large batteries which could be easy to dismantle and clean

The cow, when we read the site http://scps.fr/produits/accumulateur-nizn/ we only see interest in NiZn and we wonder pkoi it is not yet on the market, apparently it was linked to problems of low number of recharge cycles.

I quote:

The nickel-zinc battery (NiZn) has always been considered as an economical and high specific energy system. But previous attempts at development and marketing had failed due to very poor cycling ability: the number of cycles (charges / discharges) achievable was (by?) too insufficient.

* The technology developed by SCPS: completely eliminates the cycling problem,
* fully retains the economic and energy characteristics of the system,
* makes NiZn a high power battery.

* General characteristics of the NiZn SCPS: excellent cycling ability,
* strong powers delivered,
* high specific energy,
* suitability for high charge and discharge regimes,
* aptitude for deep discharges,
* wide range of operating temperatures,
* great security in all conditions of employment,
* low cost per kWh,
* respect for the environment and human health,
* ease of recycling at end of life.

The characteristics of the NiZn SCPS system are demonstrated and validated. It is ready to be widely industrialized and marketed, for stationary and traction applications.

More economical than any other industrial battery system in terms of total usable kWh, including compared to the lead accumulator if we integrate the difference in lifespans and aptitude for deep discharges, the NiZn presents also technical and economic advantages vis-à-vis the various existing systems.

* Compared to lead and nickel-cadmium batteries, NiZn: ​​offers very superior performance,
* does not contain heavy metals.

* Compared to the nickel-metal hydride accumulator, the NiZn: ​​brings similar or even improved performance,
* only requires much smaller amounts of nickel per kWh,
* does not pose a problem of geopolitical availability of anodic materials
(particular situation of the rare earths necessary for the hydrurable metal),
* is of a much lower cost,
* is totally and easily recyclable.

* Compared to lithium systems, NiZn: ​​has close practical performance for all types of "industrial" configurations (penalized for Li-ion in volume and mass characteristics compared to configurations for portable applications),
* does not present any security problem, whatever the conditions of use (and does not require a complex electronic device for management by accumulator in a battery),
* offers a cycle life at least equivalent, and a longer calendar life,
* is not likely to pose a problem of availability of the components (lithium carbonate),
* is of a very lower cost, particularly in "industrial" batteries,
* is fully recyclable at low cost and safe, by widely industrialized processes.

By cons I have not found a specific datasheet of a scps product (battery, battery ...), even a prototype or demonstrator ... a page speaks of a cost of about 1/3 compared to the Li Ion.

NiZn battery

The need for batteries for energy storage for stationary and mobility uses is constantly increasing, as are requirements for storage systems to be efficient, safe, low cost, low environmental impact and easy to recycle .
The nickel-zinc accumulator known since the end of the XNUMXth century meets many of these requirements ... but until recently could not be used repeatedly like the accumulators marketed today: the formation of dendrites of zinc and the massive redistribution of zinc during the cycles limited the lifespan to a few tens of cycles.

* The accumulator developed by SCPS lifts this mortgage, thanks to the combination of two components which go into the manufacture of the zinc electrode: a metallic copper foam used as mechanical support and current collector,
* a mixture of conductive ceramic and co-additives associated with the active mass.

By completely suppressing the formation of zinc dendrites and considerably reducing the redistribution of zinc during charge / discharge cycles, more than 1000 cycles are obtained with a discharge depth of 80%, without adding water thanks to recombination gases formed at the end of charging.

The nickel and zinc electrodes, which are plasticized on a metal foam support (nickel for the positive, copper for the negative), can be produced in a wide range of thicknesses, from 0,3 to 1,2 mm.

Obtaining a low internal resistance (very concentrated electrolyte, single-layer microporous separator), the reduction of passivation phenomena of the zinc electrode, and the adaptability of thickness of the electrodes, allow the NiZn accumulator to to be both an energy and a power system.

* The validation of the technology, through various official expertises of industrial groups (EDF, AREVA), R&D centers and Universities (CEA, Bar-Ilan University of Tel Aviv), is confirmed for everything concerning: the technical characteristics of the Technology,
* its cost,
* its ability to be easily industrialized,
* its compatibility with environmental constraints,
* its adequacy with varied application specifications.

SCPS holds all the intellectual property rights and know-how necessary for the industrial and commercial implementation of this exclusive technology.

In fact it is typical of large French nuclear partner organizations such as Areva, CEA, etc.. good for very large projects like nuclear (not yet from Chernobyl French) but hyper ineffective for small projects (see CEA for liquid crystals which for his 1980s patents on these liquid crystals used and essential in liquid crystal monitors and tv, were all happy to get over it with a lot of pain and late alms compared to the hundreds of billions of this market mowed down by Asians !! € 100 per instructor for 1 billion wealthy)
So the same, we are sure that these NiZn patents will be badly exploited, even stolen and that in France, alone, we will be the last in the world to have small NiZn batteries with 200 recharges !!

Obvious, confirms what I have just written, our large French bouzins miss the practical practical applications for the general public reserved for Asians (the armies also block if it is interesting !!).
Exactly like the patents on liquid crystals, keys for liquid crystal displays rotted in the drawers before being used in Asia, which, from legal threat, gave alms to the jackpot !!

To believe that the French Lobbies made patents to block competition on other technologies !!

[dedeleco]

I recopy my post here on
https://www.econologie.com/forums/post183216.html#183216
to make my remarks clearer here:
These batteries are not new, 110 years and more, but with the practical problem of reliability of all the batteries which means that since we have not yet taken the batteries to replace the fuels !!
See basic info:
http://fr.wikipedia.org/wiki/Accumulateur_nickel-zinc
http://en.wikipedia.org/wiki/Nickel-zinc_battery
Finally the minimum to know for the different types of batteries:
http://en.wikipedia.org/wiki/Galvanic_cell
http://de.wikipedia.org/wiki/Galvanische_Zelle
But nothing in French minimum! (remains to be written while translating)

When recharging, these oxidation products are reduced to metallic zinc, which redistributes irregularly in the electrode, and generates anarchic growths improperly qualified as “dendritics”, leading to the short-circuiting of the accumulator.

So max 200 refills !!
This fundamental problem of short circuit dentrites exists with others like Li and a lot of work and patents to work around it, effectively ???????
For NiZn, I doubt it because in 2 years no multiplication of its use and no scientific info on the trick to solve this problem and give confidence !!!!

A real ideal battery ?? No ???
http://en.wikipedia.org/wiki/Zinc-bromine_battery

The primary features of the zinc bromine battery are:

* High energy density relative to lead-acid batteries
* 100% depth of discharge capability on a daily basis
* High cycle life of> 2,000 cycles at 100% depth of discharge, at which point the battery can be serviced to increase cycle life to over 3,500 cycles
* No shelf life limitations as zinc-bromine batteries are non-perishable, unlike lead-acid and lithium-ion batteries, for example.
* Scalable capacities from 10 kWh (0.036 GJ) to over 500 kWh (1.8 GJ) systems
* The ability to store energy from any electricity generating source

Two examples of zinc-bromine flow batteries are ZBB Energy Corporation's Zinc Energy Storage System (ZESS), and RedFlow Technologies' Zinc Bromine Module (ZBM).

These battery systems have the potential to provide energy storage solutions at a lower overall cost than other energy storage systems such as lead-acid, vanadium redox, sodium sulfur, lithium-ion and others.

Two are needed for 1,34V or 3 for 1,8V

[chatelot16]

it seems that these batteries are on sale elsewhere than in France
http://www.amazon.com/PowerGenix-ZR-PGX ... B0029NZVZ0

even if the maximum number of cycles is lower than NiCd like NiMh we also have a number of cycles disappointing it could be a good solution

other note the NiZn have a voltage which rises at the end of the charge, so it is easy to make reliable automatic end-of-charge chargers, unlike the NiMh

for heavier use like an electric car, the low price of zinc and the simplicity of the electrolyte, caustic potash gives me some idea: it could be usable with a mechanical repair every 100 cycles, or even an automatic scrubbing by moving plates ...

the gain in price compared to lithium makes it possible to envisage all kinds of solution

I like lead because it is enough to put 2 lead plates in acid for it to work: I have the impression that with NiZn it is also simple, even if it is impossible to to make a reliable closed battery for 1000cycle, a cheap battery to build yourself and to clean all 100cycle would suit me very well: and in addition without danger of explosion like lithium

there is going to be zinc soaking in jars ...

do not throw the dead NiCd or NiMh anymore, I will recycle to recover the nickel!

[dedeleco]

I like lead because it is enough to put 2 lead plates in acid for it to work

uh, uh, and a lot of development afterwards to start a car !!

there is going to be zinc soaking in jars ...
don't throw away dead NiCd or NiMh anymore, I'm going to recycle to recover nickel

Uh even more development after still necessary.
The Cu CuSO4 cell] [ZnSO4 Zn, it easily walks the fingers in the nose
http://en.wikipedia.org/wiki/Daniell_cell
but not reversible does not recharge, while one obtains a powder of Cu and Zn swimming, if one tries to recharge (personal memory).
The other batteries in Zn, Li, etc .. same problem. Not easy at all.

So at chatelot16, the chemist, "there will be zinc quenching" long time "in jars ..." if we send him all our dead NiMh batteries !!
And if different patent it will defend it much better than our big books !!

No one was interested on October 26, 2009 !!
Like a lot of subjects on econology who fall asleep waking up !!!!

Ahhh, these p ..... bridles!

But there is a problem anyway, I took the trouble to examine the patents deposited by SCPS on espacenet and there is anticipation almost everywhere ... In other words, that means that they invented something that already existed. There are dozens, maybe hundreds if you look carefully, of European prior art, Asian, American, fallen into the public domain.
