Default Silver-Zinc Batteries

Anybody familiar with this technology?

The next year or two should prove very interesting. The people upset about lipos probably haven't seen anything yet. I'll make the popcorn....

1.55v may be something more usable.

From what i have seen and heard of over the past two years it has been NIMH that has received the bashing from the LIPO guys not the other way round, i use lipo in 18th and NIMH in 12th so i appreciate the benifits of both. If these new cells come into the sport then i will welcome them with open arms as these would be a great replacement for NIMH in both 12th and WGT

It doesnt matter how excellent and super any battery technology is... the R/C community will melt down in petty bitching just as it does with any new technology.

This is so true. If it is not my {insert item} is better then your {insert item}, then it is the cost.

The important question is can it deliver amps. We use LiPoly, not LiIon because of this.

That's what I'm wondering. Real world applications are way different then RC applications.

Think about the article for a second. If this is to replace Laptop Lithium Ion batteries, then yes, you can almost assume that these batteries will not adapt to the R/C community in terms of having enough amps to drive our cars.

The A123 cells have a better chance of becoming the new standard than Zinc Silver batteries.

But this was a nice article.

Silver zinc cells have some issues thatneed to be overcome. Some of the recent improvements to these cells have also caused increased internal resistance. We need to have cells with extremely low internal resistance to support the currents that we draw.

When you cycle a silver zinc cell the zinc electrode degrades very fast. This can cause dentrites formations that can pierce the seperator. Once this happens the cell will short and performance is compromised.

There are many new chemistries out there and some may show some promise in a few years. Silver zinc cells are used in very specific applications and have a replacement schedule that may be as low as 300 cycles. This chemistry is not new but has been improved some over the years.

Good thing I haven't bought any LiPo packs yet. I like my popcorn with butter. Gotta warn ya tho, popcorn gives me gas.
