My! You do seem to enjoy wallowing in your ignorance.  I suggest you use a dictionary and look up definitions for "cell" and "battery".

Goodbye as you seem to be to close to your username.

The Solid State Battery does exist.

 

Not even Wikipedia agrees with you.

 

https://en.wikipedia.org/wiki/Solid-state_battery

 

A solid-state battery is a battery technology that uses solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes found in lithium-ion or lithium polymer batteries.[1][2]

While solid electrolytes were first discovered in the 19th century, several drawbacks, such as low energy densities, have prevented widespread application. Developments in the late 20th and early 21st century have caused renewed interest in solid-state battery technologies, especially in the context of electric vehicles, starting in the 2010s.

Materials proposed for use as solid electrolytes in solid-state batteries include ceramics (e.g., oxides, sulfides, phosphates), and solid polymers. Solid-state batteries have found use in pacemakers, RFID and wearable devices. They are potentially safer, with higher energy densities, but at a much higher cost. Challenges to widespread adoption include energy and power density, durability, material costs, sensitivity and stability.

Is Sinopharm's vaccine an improvement on Sinovac? And while Chulabhorn was able to get more Sinopharm, it only proves that Sinopharm was immediately available. It says nothing about other vaccines' availability or even, for that matter, the further availability of Sinopharm.

It does seem likely, though, that considerations that had nothing to do with public health trumped those that did. 

Sinopharm is 73% compared to Sinovac 52% and AZ 90%+, so yes is better, but still not the best, though Sinopharm is shown as the highest priced of all vaccines. It has just been announced Thailand is ordering another 28 million doses of Sinovac, enough said on that as Anutin had a beaming smile when announcing, I wonder why? What I am interested in is the Australian government has now decreed AZ is only for over 60's or special request and ordered 40 million Pfizer to compensate. The lab in Aust is apparently going to manufacture 50 million doses with delivery of a million a week since April/May. So it looks like about 40 million doses of AZ are going to be available. The uptake on the AZ has been slow in Australia  due to blood clot issues, so there are probably a few million doses sitting around already, would be nice if these could make there way to Thailand. But probably not for the usual reasons.

Brings back memories of working in China. Went to go to the local supermarket, was in a basement. Got half way down the stairs and driven back by this unholy stench, yep durian Right up there with some of the worse smells of China, and there were a few contenders. I am more used to the aromas of Asia now.

The fact that you don't know the difference between "cell" and "battery" is hardly the dictionary writers' problem.

Correct it is yours for pushing a flawed definition if you know better.

When you put cells in series the voltage adds up.  Two 6 volt cells in series generates 12 volts.  Basic physics which any bright schoolchild will know about.

So why confuse cells vs batteries in the supplied definition? Maybe the dictionary authors as you supplied are not so bright and their definitions are best ignored?

As I pointed out, dictionaries are descriptive not prescriptive.  They don't lead, they follow. And since virtually the whole engineering world and the companies that manufacture them call them solid state batteries, maybe  it's them you should be correcting? What do they know, after all? It's not like they've devoted billions of dollars and years of research on them.  Please, tell them that it's a misnomer to call them solid state batteries. I am sure that your assertion will be greeted with all the respect that it deserves. And who  knows, you might even feel inclined to share with them, at least, a link to those mysterious specifications you keep on referring to. It seems to be a very private joke that amuses you only. Come to think of it, your dissent from the popular usage of solid state batter is also very private, very peculiar, and very special to you. Maybe you should get out more.

Read the specs you supplied you supplied against the claims you have made. You fail every time, or simply cannot admit your failures. 50% was the specification you could not find, go away and find it, you may be a better more informed person for doing this.

It is not up to me to correct marketing warble that the common misinformed punter believes, I deal with accuracy. If you are prepared to accept the marketing jingle, well then drink the kool aid as well.

Until you can come up with real facts why not leave it alone.

Except to virtually everyone but you.

The meanings of words and phrases arise out of usage:  not out of dictionaries.

Dictionaries are descriptive, not prescriptive.

 

Go back to quoting specs you do not understand, that was funnier.  But the term solid state is in the dictionary as is battery, but just for your ongoing education the term "Lead Acid Battery" is not in the dictionary either, somehow my fault as well?

Could you point me to a proper dictionary that has a definition of "solid state battery", please.  Neither Oxford nor Cambridge dictionary has it.  And assuming it might be an Americanism, I tried Websters and drew a blank.

You have to be a bit more adaptable in dictionary usage. Solid State as one search term then battery as a secondary search term. But thanks for assisting in proving the point that Solid State Battery does not exist.

Pretty much the rest of the world doesn't care about the etymology or appropriateness of the phrase "solid state battery and certainly doesn't need a schoolmarm to object in vain to its use.

Of course, if you want to enjoy your own private version of the English language, that's your right. It might hinder communication with others. But, after all, what's a language for if not to not communicate?

 

No I use a thing called a dictionary for definitions, perhaps you have heard of it before?

Care to be more specific? I suspect you misconstrued something.

And as for the phrase "solid state" being misapplied, thanks for the pedantry. If I had coined the term, you'd have a point. But I didn't, so you don't. It's what that kind of battery is being called, so it's best you learn to live with it.

Read the specs, it looks like you need the practice and you will find the term. These are the specs offered up by yourself as proof, unfortunately it is only serving as proof of your apparent inability to understand specs.  As for the term Solid State, it is a term used by marketing and has no basis in science. It originated when household electronics went from vacuum tubes to transistors and was used to promote the "Modern" appliances. So how is it possible  to have a "solid state" battery? And do address the questions posed and not head off on flights of fancy and quotations of incorrect specs again.

I don't know where you got that 50% capacity nformation from. I do know that current Lithium liquid electrolyte batteries have to limit their charge to around 60% of capacity in order to stop the growth of dendrites.

Also, I don't understand why you're comparing the charge capacity to actual charging limits re different kinds of  batteries. Even if lead acid batteries were able to hold the same percentage of potential capacity as a lithium liquid electrolyte battery or a solid state battery, the actual total kwh they could accumulate would be greatly different. If, after this explanation, you still cannot understand specifications, I will feel responsible for having failed you.

The 50% charging limitation came from the information you supplied. Like I said not my problem if you cannot understand specifications. But here is a challenge for you, define solid state in terms of batteries?  Hint the term is being incorrectly applied.

One of the reasons they're pushing it is because it's what they can get now.

Another reason may be that last year CP bought 15% of Sinovac. Also a few weeks ago it was announced by Chulabhorn Royal Academy that they would import Sinopharm vaccine (still Chinese but better than Sinovac), 5 weeks later it arrived, so it is proven that other vaccines can be acquired at short notice. Last year the private hospitals were trying to import vaccines for their use, blocked by the government. Eventually the government allowed the importation of Moderna and maybe a few others, but delivery late this year. So basically the government has either dropped the ball or have been trying to limit the vaccine supply purely to Sinovac and the locally produced AZ for probably the usual reasons.

Well, I don't know how to break this to you but your knowledge is wrong. Or, maybe someone somewhere thought about it but did nothing. Billions of dollars are now being spent on development. Clearly, what you know doesn't extend to the fact that solid state battteries are already being manufactured. 

Solid Power now producing large form factor 22-layer 20 Ah solid-state cells, pathway to full automotive performance compliance
"Solid Power, a developer of all solid-state batteries for electric vehicles, announced that its Louisville, Colo. facility is producing 20 Ah multi-layer all solid-state lithium metal batteries on the company’s continuous roll-to-roll production line.

In October, Solid Power had announced the production and delivery of the company’s first-generation multi-layer, multi-ampere hour all solid-state lithium metal cells. Solid Power’s sulfide-based all solid-state lithium metal batteries are manufactured using lithium-ion industry standard processes and automated equipment."

https://www.greencarcongress.com/2020/12/20201216-solidpower.html

They are calling it solid state, however has a charging current limitation of 50%. I was using standard lead acid cells back in the 80's that were good for 25%. So no not really earth changing yet. Interesting yes, but not the full breakthrough to something like a capacitor which is what needed. If they keep throwing money at it they will make gradual improvements in efficiency until one day the breakthrough should be made. If you cannot understand specifications that is not my problem.

Do you mean an additional three meters for the rod, so the OAL of the rad would be 6m?

Yes, the rod needs to extend into the soil past the tube. So if 2metre tube would need about 4 metre rod. They generally sell rod joining clips at the same store.

Cheers

A system we used in North West Australia was to insulate the top of the earth rod. Basically get a piece of PVC tube and push it into the ground as far as possible, a couple of metres minimum. Then insert an earth rod through the tube into the soil for a couple of metres. We had dry rocky soil and used to use an airtrac to drill 3metres for the tube and 3 metres for the earth rod. This then puts the earth point below the surface effects of the lightning strike, which diminishes rapidly with depth.

The Tesla S has a range of up to almost 900 kilometers. So it has more uses than just as a runabout. And of course, huge progress is being made on batteries. By 2025 solid state batteries will almost certainly be in use. They can store at least twice as much energy as the most advanced current lithium ion batteries. are not flammable, and can be charged quickly.

To my knowledge they have been trying to come up with a solid state battery for the last 50 years, and they will be available in 3 1/2 tears, I will just hold my beer and watch, lol.

Seriously I think the replacement for hydrocarbon based fuel will be Hydrogen. Briefly generate Hydrogen from water using renewable energy, convert hydrogen to ammonium (NH3) as a liquid for transport. Fill car with ammonia and then catalyse back to hydrogen, fuel cell and a hybrid type vehicle with a smallish battery. That I can believe as opposed to pure EV. Oh and there are companies working on this now, like Aramco, Total, BP, Chevron, Hyundai, Toyota that I know of.

It sounds like there will be a total of 3.5 MM doses of AZ this month. Previously someone (government, AZ, SBS?) committed to 6 MM doses.

 

1.9 MM delivered (1.8 MM last week, some locally produced, 117K delivered from SK Bioscience in South Korea in February), with another 600K and 1 MM maybe due today, tomorrow, next week, or by 30 June.

 

10 MM doses of AZ due in July.

 

Can't see them making up the 2.5 MM backlog, and the 10 MM in July. Might be lucky to get what 6 MM on 12.5 MM?

 

Will be interesting to see what happens when second shots start rolling around mid/end Sep. Who gets a first shot, and who gets a second shot? Throw the syringe in and let them fight for it.

 

 

Meanwhile Chula says the second dose of Sinovac is the bees-knees.

 

https://www.newsdirectory3.com/chulalongkorn-university-reveals-research-results-after-2-injections-of-sinovac-found-that-the-immune-system-inhibited-the-infection-higher-than-50/

 

They should perhaps look at the Indonesian experience before publishing data. Note the number of deaths of healthcare workers vaccinated with Sinovac. Sinovac is and always will be low on the totem pole of acceptable vaccines. I wonder why they keep pushing it, something CP perhaps?

Dear Mr Mayor. Congratulations on buying the worlds least effective vaccine for your Thai residents. Your country and yourself continue to ignore the long term visa holders that support the economy by simply staying here. When you have a good vaccine available, please know that all of us would like to take that. If I were offered the Chinese vaccine, I and many of my friends here will simply say 'no thanks'. Is there another way to say what I've said to you that has more impact? Unlikely. Also unlikely that you'll ever see this post. But for the record, I had hoped you cared more about the people in this city that to offer them a bad vaccine created by the same people that brought the Covid-19 Virus to your country.

This is Sinopharm not Sinovac, Sinopharm is about 73% efficacy. Yes still not 90+% of the western vaccines, but better than 50% of Sinovac.  I know someone who had the Sinopharm and still contracted Covid, but very mild and was not hospitalised, sort of like a mild cold he said. So is effective at keeping people out of hospital/dying, just not as effective as others. Sinopharm is also the most expensive vaccine to buy of all of them.

Cheers

If I recall correctly the problem with the 90 day website was someone forgot to renew the security certificate. Well with ruthless efficiency they have worked out how to stop that happening again with this app. I have seen it somewhere they get the programming for these apps done by State-owned Krung Thai Bank programmers. So if you happen to have any accounts at KT then I hate to think what the security is like.

Cheers

But I thought the Covid Czar had taken control of this personally? Muddying of waters, blame spreading and adding scapegoats is all this is. Nothing to do with improving efficiency. Someone has realised the fan is running and there is a big supply of manure on the way.
