Of course, ProsserP, you are indeed correct about the aspect of Energy Density in reference to the Lithium Titanate Battery. I was wrong in stating that it had a higher Energy Density, when as you pointed out the Energy Density is lower for LTO batteries vs NMC batteries.
The LTO has advantages in regards to lithium plating of the electrodes over NMC batteries and no SEI film formation when fast charging and charging at low temperature.
The subject of lithium plating brings up the issue of dendrite formation that itself limits the useful life of the battery and also is a major factor in regards to battery safety. I found the following article useful in terms of understanding dendrite formation, even though it is an article all the way back from 2016:
What are dendrites, and why do they cause fires in lithium batteries? - Electronic Products
There are much more technical explanations of dendritic formation and prevention of their formation, but this one makes it easy to understand without such an intense in depth and complicated review.
It is pretty obvious that any battery that minimized dentritic formation or even prevents it would be quite adventagous for that parameter of a lithium ion battery. LTO has that advantage, but in evaluating whether one type of lithium battery is better than another there are many factors to consider and dendritic formation or lack of it is only one of those many factors, something you know about in much detail after all of your years following the lithium polymer batteries and lithium NMC batteries with Ceramic technology over at Electrovaya.
My gosh, ProsserP, how many years have you been following Electrovaya? I still read about them occasionally. They certainly are not any new kid on the block. They have been plugging around for many years. I pulled the plug after their purchase of the battery plant in Europe went south, but much has happened since then and for the better. For those not familiar with Electrovaya, Agoracom has a Hub dedicated to this Small Cap Canadian company. I suspect the future will be good to Electrovaya, but it has been a long road. Of course, that "long road" thing could easily be expanded to "it has been a very, long, long road" as it applies to POET Technologies. "Long" doesn't cover the half of it and POET has its own stumbling blocks along that journey that might in the eyes of many rival the fiasco of Electrovaya's previous experiment with owning a battery plant in Europe. Nothing is perfect, right, ProsserP?
I personally love LFP batteries and have several in small appliance applications and in 2 differeent electric bicycles, but as I have already posted I don't think there is going to be a huge nitche here in the US for LFP batteries in EVs, because of the limitation on mileage.
I am not sure which one of the links I posted in that previous post you are referring to as being guilty of coming from MSM. I posted several links and you didn't specify, so I can't address that charge definitively, but you were certainly 100% correct in drawing to attention my false claim about the superior energy density of the lithium titanate battery. I really messed that one up. That is one of the advantages of having a congenial exchange of information here on this forum. Mistakes can be focused on without having to use a personal agenda or as Jack Web used to say: "The facts, nothing but the facts". Thanks, ProsserP.
Now for the subject of SSB and Lithium Ion batteries, they too have the possibility of dendritic formation, but research continues to eliminate of minimize that situation as it applies to them.
I found the article below on the ASME site and I hope you will agree that it doesn't fit the limitations of the MSM that you described in your post. It also is a recent article with a publication date of 18 May 2021. For me, at least, I found it to be quite informative. No, I can't say I understand all of it, but it did help me conceptually about the subject.
