right now they can't make batteries fast enough. That's what all the legacy auto makers are just figuring out...
Other than Musk, nobody else wants to commit to large scale battery manufacture with the technology in flux and on the cusp of big improvements. New solid state battery technology could blow Elon out of the water and quickly make his battery gig factories obsolete. There are a lot of emerging electrochemistry's, materials and technical breakthroughs, there is a lot of money and talent being applied to the problem.

I think for semi trucks a diesel electric/battery hybrid solution seems to be the best option. The battery gets the beast rolling and the hybrid diesel running on LPG keeps it rolling. You'd need the power contained in a lighting bolt to charge the fucking thing from flat! I think the main attraction for electric drive other than environmental, is it eliminates the need for shifting gears, this will make auto driving trucks possible. It's hard for a computer to work a clutch and shift 18 gears while driving a large truck autonomously.

As far as I know Panasonic makes batteries for Tesla, unless I'm missing something.

it's the raw materials......there is such a growing demand for batteries that raw materials are getting harder to find. You will see many of the new ev's coming out will have limited range due to small battery packs.

I think this is the advantage that Tesla has over its competitors. Tesla's efficiency ratings for ALL of its vehicles are in the low 5.0 range. The next nearest competitor is at a 6.6. What does this mean?

The least efficient Tesla vehicle is over 20% more efficient than the next nearest competitor. Tesla is getting more range per pound of vehicle weight from its battery packs than its competitors. Tesla isn't building larger battery packs to try and get more range on its vehicles. It's engineering more efficient battery packs than anyone else.

Why does any of this matter? The reason it matters is because you will get the most bang for your buck when buying a Tesla vehicle. This means you will get the longest range, greatest efficiency, per dollar you spend with Tesla than any other vehicle. For other vehicles to get the same range as Tesla, they would have to add weight with additional batteries, which would cost more to produce, and they would either need to increase their prices, or sell their cars at a loss.

LG Energy Solutions and Samsung SDI have both reportedly completed the first sample cells of Tesla’s 4680 battery cell as they eye a big contract from the automaker.

Last year, Tesla unveiled its plan to produce its own new tabless battery cell in a bigger format with a new chemistry.

The automaker claims to have solved some major issues that were preventing the industry from producing bigger cylindrical Li-ion cells in a new format called 4680.

Tesla’s new 4680 battery cells have the potential to be cheaper, more efficient, and, therefore, enable a longer range or smaller battery packs.

Solid State Batteries - Autumn 2021 mass production in Japan. Is it FINALLY happening?

Solid state batteries are the long-promised Holy Grail of battery technology. They're smaller and better than existing Lithium Ion batteries. They charge more quickly and last much longer. What's not to like? Trouble is, no-one's managed to mass produce one at any useful scale yet. Turns out it's quite tricky to make them reliable! Now though, two major Japanese companies are finally firing up their full production lines. So will 2021 be the year?

Tesla Energy Is Reportedly on the Hunt for Mean Social Media Posts About Musk
Workers were also purportedly instructed to search for customer complaints and ask them to delete their posts.

Tesla’s clean-energy division Tesla Energy has an entire team dedicated to scanning the internet for customer complaints and people badmouthing its CEO Elon Musk, according to a new Insider report.

Two former employees that spoke with the outlet under the condition of anonymity said that in addition to resolving issues that customers complained about online, Tesla staff were instructed to ask customers to delete their posts.

A team of more than 20 employees searched for customer complaints on social media and review sites, while a separate team of nine people hunted for posts that targeted Musk specifically, an ex-employee said in an interview with Insider. Their former role involved handling complaints through Tesla’s official customer support service as opposed to those posted on social media. However, they told the outlet they were also expected to comb through the internet for pissed off Tesla customers during their “downtime” on the job—which was all but non-existent as they already worked through breaks to avoid getting swamped with issues from Tesla’s customer service pipeline alone.

Another ex-employee who worked as a manager at Tesla Energy until last year, said that staff tasked with scouring social media “would basically just look up #TeslaEnergy, #Elon, just anything that has to do with Tesla and energy and Elon.” This seems to be supported by a job listing Tesla put out earlier this year looking for full-time staff to “address social media escalations directed at the CEO,” as first spotted by reporter Jay Boller on Twitter. A smart move on Tesla’s part given the track record of expensive legal repercussions for Musk’s bad tweets.

SpaceX Falcon Heavy to launch NASA ocean moon explorer, saving the US billions (teslarati.com)

SpaceX Falcon Heavy to launch NASA ocean moon explorer, saving the US billions

In a move that’s likely to save the US taxpayer several billion dollars over the next few years, NASA has carefully extricated a mission to one of Jupiter’s ocean moons from the claws of its own Space Launch System (SLS) rocket.

Known as Europa Clipper, the six metric ton (~13,300 lb) spacecraft will instead launch on a SpaceX Falcon Heavy rocket for less than $180M. Had Falcon Heavy not been ready or NASA shied away from the challenge of switching launch vehicles, sending the ~$4.25 billion orbiter to Jupiter could have easily added more than $3 billion to the mission’s total cost. Instead, Europa Clipper will be able to launch one or two years earlier than SLS would have been ready and at a cost that’s practically a rounding error relative to the alternative.

Remember he opened up a Parler account. Imagine how long his ignore list is there?

I figure he’s on Parler, arguing with himself.
He's a sensitive soul who calls everybody an idiot who disagrees with him.

He's on another forum as Gomez something, the grammar Nazi, so maybe he's venting there or FB.

I understand he is or was a school teacher and I can imagine the habit of calling people idiots extended to his students. They must have had fun triggering him in class, guys like us would have been expelled for sure! :lol:

Chinese university develops new material to accelerate solid state battery production

A team at University of Science and Technology of China has developed a new material that could potentially help lower the production costs of solid state lithium batteries and accelerate their commercialization into EVs. The new material, lithium zirconium chloride, offers a reduced material cost and necessary performance, all while remaining stable.

Solid state batteries have become a long-promised and underdelivered battery technology that is often jokingly referred to as perpetually “two years away.”

While there have been several breakthroughs over the years through experimentation with different materials, electrolytes, and cathodes, the largest hurdle for solid state batteries remains the means of cost-effective mass production, to compete with traditional lithium-ion batteries.

Despite this apparent scalability issue, some automakers have already promised this technology… although many have already backpedaled on these statements. For example, Fisker Inc. announced a solid state battery breakthrough capable of one-minute charging in 2017, only to completely give up on the project years later.

More recently, Chinese Automaker NIO has promised a 150 kWh, solid-state battery to debut in its upcoming ET7 sedan, capable of 1000 km (621 miles) of range. Later that day, NIO’s CEO tweaked the company’s verbiage describing the battery as “semi-solid state” due to the presence of liquid electrolyte.

While a genuine, scalable solid state battery has yet to see production, a team from the University of Science and Technology of China believes it may have discovered the material necessary to accelerate this process.

Chinese team’s new material could hurry solid state battery production
As published on Nature Communications this week, a research team from the University of Science and Technology of China led by Professor Ma Cheng believes its new material will help accelerate solid state battery production, due to its low-cost and comprehensive performance.

The study, titled A cost-effective and humidity-tolerant chloride solid electrolyte for lithium batteries, details the new material called lithium zirconium chloride or Li2ZrCl6, and how effective it can be:

Its raw materials are several orders of magnitude cheaper than those for the state-of-the-art chloride solid electrolytes, but high ionic conductivity (0.81 mS cm–1 at room temperature), deformability, and compatibility with 4V-class cathodes are still simultaneously achieved in Li2ZrCl6. Moreover, Li2ZrCl6 demonstrates a humidity tolerance with no sign of moisture uptake or conductivity degradation after exposure to an atmosphere with 5% relative humidity.
According to the study, Cheng’s team was able to successfully reduce the cost of the raw material to $1.38 per square meter (m²) for 50 micron thickness. For context, the cheapest solid state electrolyte cost was previously $23.05/m².

Solid state electrolyte materials have serious potential to replace liquid electrolytes entirely, but only if mass production can balance both cost and performance.

Sourcing new abundant materials
According to the study, Zirconium is a non-lithium element that exists in abundance in the Earth’s crust, compared to other materials used in solid state batteries. This can also lead to more scalable and cost-effective production in the future.

According to CnEVPost, Cheng and his team will continue their research to improve the stability of Li2ZrCl6 to lithium metal, followed by the development of energy dense, soft pack batteries based on this new material.

Furthermore, they are working with a number of companies to advance the commercialization process of solid state battery production.

Electrek’s Take
As we always say when solid state battery news comes up, take this all with a grain of salt. While this seems like another breakthrough for solid state battery production, this research has not yet proven scalability for affordable commercialization.

Talking to “a number of companies” could be the next step, as these researchers move into more robust prototypes, but that has yet to be seen. Who and where these companies are also remains unclear, but they assumedly are in China near the University in Hefei.

Perhaps we see this new lithium zirconium chloride solid state battery in the NIO ET7 someday. But for now, it’s just research. That being said, we are rooting for anyone and everyone achieving these sort of breakthroughs no matter how large or small.
