I’ve been trying in earnest to obtain an independently sourced (e.g. impartial, non-vendor sourced) White Paper study that explains (empirically) the operating characteristics of SiO2 battery technology, but heretofore after several search tries and forum request (to SiO2 advocates), have been left empty handed...I do however believe that SiO2 batteries may be second to none in extreme weather applications (i.e. utility applications) and possibly suitable in general service applications as well...Any assistance or search results regarding a empirical White Paper are much appreciated :) .......(please, no conjecture...)3 tons

Did you search on google scholar? I think that's their name for academic work here

3 tons,I'd have to say that Lithium Titanate are more than the equal of SiO2 for cold weather performance. However, they do cost an arm and a leg and your first born son.My opinion is that the LiT also blow LiFePo4 out of the water, excepting energy storage density."Batteries with lithium titanate anodes have been known since the 1980s. Li-titanate replaces the graphite in the anode of a typical lithium-ion battery and the material forms into a spinel structure. The cathode can be lithium manganese oxide or NMC. Li-titanate has a nominal cell voltage of 2.40V, can be fast charged and delivers a high discharge current of 10C, or 10 times the rated capacity. The cycle count is said to be higher than that of a regular Li-ion. Li-titanate is safe, has excellent low-temperature discharge characteristics and obtains a capacity of 80 percent at –30°C (–22°F)..Feb. 11, 2021"From https://batteryuniversity.com/learn/article/types_of_lithium_ionI will be most excited if some one finds a genuine white paper, so thanks for starting this thread.

White papers are recognized only from accredited engineers or scientists.When a scholar creates a white paper (he) is essentially nailing his family jewels to the barn door.Pons and Fleischmann found out in the late eighties what happens to people who create a white paper frivolously. Both were staked to anthills.A white paper will explain specifics about a subject and must be convincing to the point where it can be used as a footnote in further research.First step in creating a white paper is: What questions do I intend to answer?

“ First step in creating a white paper is: What questions do I intend to answer? ” Exactly!,,But this runs 180 degrees contrary to today’s politically motivated (i.e. gov’t cash infused) impulse at ‘Outcome based’ science, aka the reemergence of medieval scientism (corrupted data, with wholesale conformity) - may Aristotelian critical thinking (little understood) R.I.P.3 tons

I think the RbFrSm battery is far superior

Even so I would not really trust any monitor that shows SOC. I like to cross-check anything I can to see if it reads right. I use resting battery voltage tables for SOC to cross check the AH count for SOC to see if they "match' within reason.

The Victron ISTR has an automatic "sync" for when it thinks the batts are full. This is where monitors get out of whack for whatever reason, so a cross check is useful. I don't trust automatic anything.

It is like a digital voltmeter that starts to show higher voltage when its battery gets low. It is insidious so you don't notice it is getting off -kilter until you get a cross check with a different voltmeter.

Lead Crystal / SiO2 batteries

Unless I’m missing something, from all that I can tell SiO2 is the molecular definition for ordinary beach sand (or silica, which has ionic-transfer friendly lattice-crystallin structure), lead, and I believe some sort of mediating electrolyte, presumably an AGM like sulfuric acid paste (Though it’s not exactly clear to me why the purpose for the silica?)...Thus the interchangeable monikers of SiO2 and Lead Crystal.

Might be interesting to do a deeper dig to understand how all the physics differs from FLA, but SiO2’s exist for a valid reason - my ‘best guess’ is that this particular recipe results in an ionic-transfer ripe, freeze resistant battery...

But I could be wrong...

ISTR "Lead Crystal" is a Trademark name, not sure about "SiO2" but they are the same battery "type". The blurbs say they are different from regular AGMs in the way they describe and that is why they are different from AGMs in how they act.

I don't think it is all a scam. what would be the point of that unless it helped "Sales" bring in more buyers? There is no sales campaign that I can spot (which was pointed out) Maybe they have enough domestic consumption that they don't need to export them. Don't know, not my problem.

If you want to see a sales campaign in action to convince everyone they can't live without this new thing remember The Music Man show. Hmmm reminds me of something. :)

“ The Victron ISTR has an automatic "sync" for when it thinks the batts are full. This is where monitors get out of whack for whatever reason, so a cross check is useful. I don't trust automatic anything”

I agree, due to the lack of necessity to preform BMS cell balancing with each and every charge cycle, auto-sync’s can occasionally be few and far between, thus (due to habits) the potential exist for SOC drift...However the re-sync is based on programmed charged parameters having been met and thereafter occurs only after a several minute holding period - It’s with this in mind, and having 3 separate-source digital voltage readouts, that the Victron has so far proven reliable...No regrets ditching the former LinkLite, as the detailed smart phone windows and cycle historicity are truly outstanding...

3 tons, where the SUN usually Shines and Solar matters - lol

“I don’t think that it’s all a scam”...

Nor do I, no doubt SiO2 exist to fill a particular market niche, and it’s only reasonable that it shares a fair amount of overlap with other battery recipes...Had at the right price, could be ‘just the ticket’ for folks like PT :)
