    I guess this is related to the the self-discharge rate.

    "Most lithium-ion batteries have a self-discharge rate of between 0.5-3% per month."

    For EV, this mostly affects long term parking after fully charged, when self-discharging is higher.
    For normal usage, it's insignificant.

    Yes. But the problem with batteries in general is that their power
    and energy densities are about a factor of one hundred smaller than
    that of kerosene.

    And lithium batteries have the added problem of catching fire at
    random, and setting any neighboring such batteries alight, until all
    are consumed. Which happens way too fast for everybody to escape.

    With switching regulators, "voltage decay" isn't a problem.

    Any technology that is novel, pivital, profound and promising is

    How do you calculate the energy density of battery, per pound?

    How do you calculate the energy density of battery, per pound?
    The battery contains so much total energy in watt-seconds (Joules),
    has a mass of XX grams and occupies YY liters of volume, and can
    deliver power (watts) at maximum rate ZZ.

    The issue is particularly acute for airplanes - one cannot fly across
    the Atlantic or Pacific in a battery-powered airplane. You'll get
    maybe 200 miles, then splash.

    Yes, doesn't make sense for ICBM (M for Mobility), but perfect sense for short haul feeders.

    And how about the shipping costs of kerosene vs. electricity?
    For a vehicle, shipping costs are not the issue at all, but shipping kerosene (or coal) is far cheaper than electricity, which is why there
    are multitudes of local power generation plants versus five or so
    immense central power plants and a lot of transmission systems.

    But we have to consider incremental shipping costs. If we have to use one additional gallon of gasoline, it might come from the middle east or Russia, and we are spending billions in energy costs (wars).

    Joe Gwinn

    Joe knows so little about reality. Presently, the US exports more crude oil than we import. The problem is not getting it out of the ground. The problem is that we then burn most of it, which releases carbon into the atmosphere. But then, I suppose
    that's another area where Joe has his own opinions.

    I didn't realize kerosene was the gold standard in battery technology.

    I wonder if you realize kerosene is a factor of 3 smaller than kerosene?


    And lithium batteries have the added problem of catching fire at
    random, and setting any neighboring such batteries alight, until all
    are consumed. Which happens way too fast for everybody to escape.

    It is easy to separate the stupid people in sed from those who actually know how to read, by claims like this.

    Lithium batteries don't catch fire at random. Like all batteries, their self-discharge rate gets higher as they get older, which heats the battery even when it isn't doing anything useful, and raises the self-discharge rate. The fact that the core of the
    battery is warmer than it's environment is easy to monitor. Thermal runaway doesn't set in until the core of the battery gets above 125C (for electrodes that include nickel) and about 160C for those that don't.

    If you don't pay any attention to the warning from the battery monitoring system, you might think that this happened at random, and several of or resident right-wing lunatics (Cursitor Doom and Flyguy) do have this delusion, but it is a delusion.

    NASA would beg to differ. They've had a battery powered aeroplane that has flown around the world without landing. It's covered with solar cells, which recharge the battery every day, adn it doesn't fly fast, but it hasn't splashed yet.

    And how about the shipping costs of kerosene vs. electricity?

    For a vehicle, shipping costs are not the issue at all, but shipping kerosene (or coal) is far cheaper than electricity, which is why there
    are multitudes of local power generation plants versus five or so
    immense central power plants and a lot of transmission systems.

    Some of that is history. Most of the local power generating plants were built before 500kV DC transmission links were practical.

    And lots of parts of Europe put generating plants in city centres where the wast heat from the generator can be exploited for district heating.

    The shipping cost of brown coal is lot higher than kerosene, and power generating plants burning brown coal tend to be built at the brown coal field.

    We choose to outsource acquisition of oil and gas to less fussy nations, so we don't have to do messy things like drill oil wells and mine minerals ourselves. But there is no non-political reason why we cannot drill and mine in the US.

    Joe knows so little about reality. Presently, the US exports more crude oil than we import. The problem is not getting it out of the ground. The problem is that we then burn most of it, which releases carbon into the atmosphere. But then, I suppose
    that's another area where Joe has his own opinions.

    When the argument turns ad hominem, it's a sign of lack of ammunition.

    There's nothing ad hominem in pointing out that an individual has his own opinions. The implication is that they are a bit silly - as indeed they are.

    There are many more like this.

    None of which mean what Joe wants them to mean.

    Summary:

    Yes. But the problem with batteries in general is that their power
    and energy densities are about a factor of one hundred smaller than
    that of kerosene.

    I didn't realize kerosene was the gold standard in battery technology.

    I wonder if you realize kerosene is a factor of 3 smaller than kerosene?

    Do you really mean that?


    And lithium batteries have the added problem of catching fire at
    random, and setting any neighboring such batteries alight, until all
    are consumed. Which happens way too fast for everybody to escape.

    It is easy to separate the stupid people in sed from those who actually know how to read, by claims like this.

    Ad hominem. Running low on ammo again.

    What you are looking for are Ragone charts, which plot specific power
    density versus specific energy density, of both weight in kg and
    volume in liters, on log-log paper.

    When one does this, fossil fuels and combustion engines are in the
    upper right corner, and all battery stuff is down toward the lower
    left corner.

    But it's hard to find Ragone Charts covering both batteries and fossil
    fuel. Mostly one sees only plots showing only the battery corner.

    But it matters a lot for aviation. Consider this, reported by
    Aviation Week:

    The basic reason is to handle pulse loads that solar cell sources

    The big breakthrough would be the invention of a far better
    superconductor than what we now have. This would solve a number of
    problems, including:

    Energy storage, in a big super conducting toroidal inductor.

    Fusion by magnetic containment. Current containment fields are far

    There was a plan for a miles-diameter superconductive inductor, flat

    Superconductors can't make super high fields. MRIs are teasing the

    I do remember that. Don't recall why no toroid. Hmm. Probably to
    keep the local magnetic field low enough for storage to work.

    edges of self-quenching.

    A quench is fairly dramatic. I've seen quenches of smaller NMR

    That is the present problem. When I speak of ten time the field, I
    mean well away from quenching.

    If it's storing a significant amount of energy, a quench will likely
    destroy the storage system.

    Lithium batteries don't catch fire at random. Like all batteries, their self-discharge rate gets higher as they get older, which heats the battery even when it isn't doing anything useful, and raises the self-discharge rate. The fact that the core of
    the battery is warmer than it's environment is easy to monitor. Thermal runaway doesn't set in until the core of the battery gets above 125C (for electrodes that include nickel) and about 160C for those that don't.


    Yes, Bozo, lithium batteries DO catch fire at random - there are numerous examples of that happening. The latest PRIME example is that of the car carrier that caught fire off of the Netherlands, sinking the ENTIRE SHIP.

    If you don't pay any attention to the warning from the battery monitoring system, you might think that this happened at random, and several of or resident right-wing lunatics (Cursitor Doom and Flyguy) do have this delusion, but it is a delusion.

    Please detail the battery monitoring system that alerted the crew of this ship.

    Yes. But the problem with batteries in general is that their power

    that of kerosene.

    And lithium batteries have the added problem of catching fire at
    random, and setting any neighboring such batteries alight, until all

    Lithium batteries don't catch fire at random. Like all batteries, their self-discharge rate gets higher as they get older, which heats the battery even when it isn't doing anything useful, and raises the self-discharge rate. The fact that the core
    of the battery is warmer than it's environment is easy to monitor. Thermal runaway doesn't set in until the core of the battery gets above 125C (for electrodes that include nickel) and about 160C for those that don't.


    Yes, Bozo, lithium batteries DO catch fire at random - there are numerous examples of that happening. The latest PRIME example is that of the car carrier that caught fire off of the Netherlands, sinking the ENTIRE SHIP.

    If you don't pay any attention to the warning from the battery monitoring system, you might think that this happened at random, and several of or resident right-wing lunatics (Cursitor Doom and Flyguy) do have this delusion, but it is a delusion.

    Please detail the battery monitoring system that alerted the crew of this ship.

    I doubt that any battery monitoring system is going to catch a defect that expands into an inferno in seconds.

    You haven't been paying attention. The "defect" is an increasing self-discharge rate, which leads to self-heating.

    If you took any battery that had self-heated to about 100C - way short of the threshold for thermal runaway - and discharged it into a load, it wouldn't be a threat any more

    Even if something did detect a short, what could anybody do about it? Dissasemble the battery pack in seconds? In a car surrounded by other cars!

    You get a much earlier notice than that, and you just discharge the battery (not fast enough to heat it up appreciably, and the battery monitoring system will allow you to keep track of that).

    You've bought into the Flyguy/Cursitor Doom alarmist narrative and haven't noticed how you have been suckered,

    Discharge it into what and for how long? According to <https://ev-database.org/uk/cheatsheet/useable-battery-capacity-electric-car>, the average capacity of an EV battery is around 70kWh. What discharge
    rate would have a measurable effect to stop the battery heating up
    appreciably in less than a few hours, and other than discharging it into something producing heat, what could be used, and how could it be

    Would it be possible to use the charging socket "in reverse", and take

    Old lighting systems for houses used acetylene (explosive), or town gas (contains

    New York City is averaging hundreds of fires a year, with dozens of

    Those fires are most likely in cheap imported bikes and scooters, but

    Every electric car has at least one big electric motor which can dissipate quite a lot of heat in the resistance of the motor windings. You don't have to spin the rotor while you are doing that (though you could probably dissipate more power if you could)
    . It would probably take some hours to flatten the battery using that as the resistive load - may be a day or so.

    It can look random to under-informed observers like you. There's actually a drawn-out sequence of events leading up the thermal run-way that ends up with the battery on fire, and it's not difficult to monitor a lithium battery for the physical changes
    that precede thermal runaway. Small lithium batteres don't get fitted with monitors. Big ones do.

    The latest PRIME example is that of the car carrier that caught fire off of the Netherlands, sinking the ENTIRE SHIP.
    https://www.youtube.com/watch?v=FlDj3xvGKno

    If you don't pay attention to the output of the monitoring system it can look random.

    How could I? You'd think that the battery monitoring system in an electric car would sound the horn if the battery had got warm enough to be on the verge of thermal runaway - perhaps 100C when the threshold can be 125C for batteries containing nickel or
    160C for those that don't.

    Whether that would be noticed in the hold of a ship is anybody's guess,

    You can detect the precursor to thermal runaway long before it becomes an immediate threat, and you can make the battery safe by discharging - into the vehicles motor if necessary (without requiring the motor to rotate).

    So what? That "a defect that..." phrase identifies an unlikely event, like a lightning strike. It has already been noted that insurance companies (who tally these things)
    haven't found it to be a problem, in comparison with alternative technologies.

    New York City is averaging hundreds of fires a year, with dozens of deaths, started by lithium batteries in scooters and such. It's not a trivial issue.

    Human stupidity is not a trivial issue, but banning a technology because idiots misuse it is something of an over-kill.

    Those fires are most likely in cheap imported bikes and scooters, but even Teslas explode now and then.

    The most recent Tesla fire in Sydney was caused by a battery which had been taken out of a Tesla. Why it had been taken out of the car hasn't yet been revealed, but excessive self-heating would be a plausible explanation. Banning the technology because
    stupid people can take foolish risks with it would be an over-kill.

    I doubt that any monitoring technology will reduce the battery hazard much.

    An odd statement from an engineer,

    I've seen videos of scooters exploding like a bomb.

    Not exactly the world's most reliable evidence, and you clearly don't understand the physics leading up the the thermal runaway is presumably what is being blamed for the dramatic event.

    How do you calculate the energy density of battery, per pound?

    -density is per extent usually, per volume for 3d things.

    if it's connected to the grid that's an option

    else you can put heat into the motors by running them stalled against
