I'm not competent to evaluate the merits of this new product, but it is thought-provoking:

Manufacturer's website

I don't know if they are already working on a battery suitable for RVs, but they claim that the device is "scalable." Does that mean both up and down the scale?

Coated silicone solar wafers? Rubber Baby Buggy Bumpers. Less lead means more CCA and cycles.

Generally "Scalable" means up but can also mean down.

If this works and is not a whole lot more expensive it may put traditional lead acid out to pasture (It won't put the companies out of business because I suspect it can be made on the same machines) If you can pack say 85 AH into say half the weight I might pick up a few feet per gallon on the old MPG chart.

It sounds like they are plating the lead over a light weight plastic substrate. Seams like it would be cheaper to mfg and lighter. Didn't Jim Varney die after he went to Washington?

Well, the world’s Lithium supply is not infinite, though they seem to be developing another big Li mine in Canada’s wealth production region of Alberta...

Ha! 3 tons gets in a shot against PT for revealing his politics! [emoticon] (which I do not share, but means nothing on this forum)

Meanwhile 3 tons, having bought into LFP, is "more Catholic than the pope" on that topic, so we adjust accordingly.

BTW "attacking" false LFP advertising is not attacking LFPs. Big difference!

LFPs have their place in the spectrum, but are not for everyone. Saying that, or calling out false advertising, does not mean you should be burned at the stake (especially for the "enhanced" version where they used wet wood if they really didn't like you!)

Huh??.... Most folks who are informed here in the lower 48 are quite aware of Alberta’s sizable contribution to our northern neighbor’s treasury (no secret about this) and with a boon of Lithium ahead their future, I would think that this attribute is something for all Canadians and the entire World to embrace - we need your Lithium!!

For the record, my view is that Canada is a Great beautiful neighbor that America is most fortunate to have, this in far more ways than just trade...

FWIW, I’ll always support attacks on false advertising, in fact this is why I’ve repeatedly asked for independent white papers!! Nor have I ever even ONCE claimed that LFP’s are for everyone, but if I must I’ll again restate because they are NOT.... BTW, no need to ‘impute’ (e.g. guess) the positions, politics, religiosity or motives of others...My PM is always available, even for touchy hot-topic questions, though my responses may be limited to a simple Yes or a No - lol

I went to the webpage, very stark with actual infomation, and in most of there upmost basice comparasons they fit inbetween normal AGM batteries and LI (they don't say what kind of Li though) would have been nice to see some actualy numbers but the only numbers they put out was for a very low capacity 6V battery.

would be interesting to see some actual info but maybe its just to new. there should be several new types of batterys in the near future as everyone is racing to come up with the newest and greatest batter you power all the electric cars we will all be buying.

Just to be clear, they're talking about silicon wafers, not silicone wafers. The chemicals have vastly different properties, despite their names only differing with a final letter e. A crystal of silicon forms the substrate that solar cells and computer chips are made on; it is a stiff and brittle material. Silicone, on the other hand, is the rubbery stuff used as a sealant or for flexible spatulas and bowl scrapers.
