    @ litesong,
    You are more than welcome to skip over/ignore any and all of my posts -- probably be doing both of us a favor.

    /and for the record, I don't hold any type of a stock position on TSLA

    Since you admit to error, obeying your desires probably isn't a favor to me & you. Glad you don't own short-sell Tesla stock...... your losses would have been great.

    @ litesong,

    Do you own TSLA stock?

    You're the one with questions, using the questions as a defense for your positions. Because you multiply admit to error, your question strategy isn't working.

    ... so I'm going to put you down for a 'yes' on that one.

    Carcus thinks his questions are rhetorical & self-answering. However, the questions of Carcus are NOT rhetorical, NOT worthy of answers, AND lead to its many errors.

    Hi Litesong:

    Carcus is adding interesting content related to batteries for BEV/PHEVs.

    I agree with you. But he neither needs to consolidate his positions with rhetorical questions, which aren't, or put words in people's mouths. His biased errors dramatically reduce the value of his information.

    Wayne......Carcus doesn't agree with your vision. Quote from Carcus, "@ litesong....You are more than welcome to skip over/ignore any and all of my posts....."
    Carcus doesn't realize tho, that I often agree with his post.....

    Hi Litesong:

    Carcus and I have disagreed on many posts here over the years. Between all of us however, we run across some pretty cool details and tech. I am grateful for yours, his and everyone's posts as I learn something from them every day.

    "Many automakers have also signed deals with BEV start-ups, battery manufacturing companies and even going as far upstream as lithium mining companies. This shows the belief the automakers have in the coming transition and how seriously they are preparing for it. Considering these aspects, Wood Mackenzie’s base case projects the market share of BEV sales will increase from 3% in 2019 to 14% by the end of the decade."

    Electric vehicle growth set to accelerate through the 2020s
    Cheaper batteries, faster charging and greater ranges will make the 2020s the decade of the electric vehicle

    ---------------

    This sounds possible to me.

    also,.. my guess on how Tesla would introduce a new and improved (but not the "million mile") battery:

    1. Show it off with the roadster
    2. In a year's time (or so) start introducing it as a "touring" version of the X/S
    3. a year after that a touring version of the Y
    4. later let it start trickling into the 3

    / I think at some point Tesla will have to provide some expectation as to how much supercharging before you'll get "throttled" (--- i.e. 15,000 kWh's worth) with the current battery tech
    // with the new battery tech, .. you can expect a higher number of supercharges and a higher rate of charge,... this should give them a new "premium" feature to sell and also have an added bonus of 'uncrowding' some of the overcrowded superchargers (once throttling expectations on the current tech are made more clear)

    then ,.. when the next upgrade in battery tech comes around ... rinse, repeat

    add ...

    If the battery happens to be the "million mile" battery, then ,,

    I would not expect it to go into any of Tesla's S3XY vehicles, ... that'll be for trucks and taxis (and energy storage) -- and I would imagine Tesla will want to maintain control of those batteries/vehicles.

    LTO cells aren't new. What's so "WOW!"?

    High C rate (very high, .. Wow!)
    High cycle life (very high, .. Wow! 20,000 cycles -- cycled daily, that's 54 years)
    Limited thermal management req'd (looks like to me)
    No problem with going 100% dod
    Safety (don't try this with a 2170):


    but, there's always downsides -- low energy density, and cost to name a couple

    People who drive a lot & obey ABC(Always Be Charging) would shorten 54 years to 20 years or less.

    How many miles do you figure "driving a lot" for 20 years would amount to?

    To me, "a lot of driving" in 20 years would be 700,000 to 1 million miles. But, it appears that "a lot of people" drive much more than my "a lot of driving". It's kinda like "a lot of teeth". :D:D:D
