Well, someone is hanging on to an increased margin !..
in 2017 Tesla sold a 129 MWh grid battery to Australia for US$65 m…(~$500/kWh)
the most recent price i have seen for similar Megapack systems is still US$400-$500 kWh !

The Astonishing Economics of the Tesla Megapack

Tesla's Megapack is getting more attention. This is because it is being built at a massive scale in Lathrop, California and is using LFP batteries. And, there is much more.

I've yet to see a cell advertise that density that isn't unobtanium. So i looked into it.
Japanese battery makers have 5.3ah 21700's coming and EVE has 5.8ahs..

Found some tests by googling the cell name. I'm actually surprised, it is said to deliver 6ah at a super low C rate.

..actually pretty impressive, i'm surprised that's even achievable, but i would personally not build an ebike battery with something other than a top name cell ( better safety )

Ahh i see mooch tested them about a week after i found out about them. Makes sense, as they are marketed towards the vape community, that they wont be a fan of continuous use at higher current.
 
Thinking of new stuff, Sodium ion batts are in, printing up an enclosure for them now. I have not sourced a charger yet. I think I am gonna have to just get an in-line unit that tracks the temp and voltage, then cuts off when it hits a specific point.... I think I can actually do this and just leave that portion in the case, it is not a BMS it is just a deddicated charger.
 
That's press release AF!
I like the sound of 450whrs/kg

Do you know if Amprius is working with multiple companies at this point?
 
LG’s 4680 Battery Production — The Tesla Space

Korean electronics company LG Energy Solutions will begin production of Tesla’s 4680 battery cell as early as August of this year, according to CEO Kim Dong-myeong.

Kim made the announcement at the Korea Battery Industry Association’s event for their Board of Directors on February 15th, in response to questions about the possibility of the company starting production at their Ochang factory in June or July this year.

The CEO clarified that the timeline could bounce around a little bit, but that it will be happening soon.

Boy, would i love to build a battery pack out of these.. i think they're 25AH each, so they'd work great as 1P..

Should be that this year, there will be two makers of these cells, so the possibility of getting some for DIY this year is rather high.

Cheap solid-state sodium battery to enter production with up to 300Wh/kg energy density​


A cheap sodium-ion battery that doesn't use expensive lithium but with the higher energy density of solid-state batteries would be a coveted achievement for spearheading electric mobility.

That's exactly the production goal of the Huahui New Energy battery maker which managed to cram 200Wh/kg of energy density in a sodium battery with solid-state electrolyte.

This is closer to the energy density of current LFP batteries in electric cars like the Tesla Model 3 RWD, rather than the 145Wh/kg to 160Wh/kg of the first cars with cheap sodium-ion battery that were unveiled last year.

While most solid-state battery makers use oxide or the more expensive sulfide solid electrolytes, the sodium battery breakthrough has been achieved by combining polymer composites. This has allowed to lower the cost of the resulting solid-state electrolyte without sacrificing performance, and the same has been achieved for the electrodes by supplementing sodium instead of lithium and coating the cathode with a combination of organic and inorganic materials:

The company is testing the mainstream layered oxide, Prussian blue and polyanionic cathode materials on the market. Among the current samples in our laboratory, the sample cycle of polyanionic materials can already reach more than 4,000 cycles. Layered oxidation's cycles can also exceed 1,800 times.

As a result, the end goal of the mass production start that the company received a round of financing for is to hit 300Wh/kg of energy density at a cost of just 4 cents per watt hour.
 
Samsung SDI to start mass-producing solid-state batteries in 2027

Samsung SDI to start mass-producing solid-state batteries in 2027​

At the InterBattery trade show in Seoul, the Samsung Electronics group company outlined plans to begin producing high-performance solid-state batteries with an energy density of 900 watt-hours per liter -- a 40% improvement from its lithium-ion cells.

Solid-state batteries are widely considered the future of storage batteries. They have short charging times and high energy density, which can extend the range of EVs. They can also be made lighter and safer than lithium-ion batteries, which contain a flammable electrolyte solution.

Samsung SDI last year launched a pilot production line in Suwon, near Seoul, and is now working to improve the batteries there while honing mass-production capabilities to improve yield.

Also in 2023, the company established a team to promote the commercialization of its solid-state batteries, marketing the product mainly to existing clients like BMW. It started shipping sample batteries to leading global automakers earlier this year.

Samsung SDI will set its production plans for 2027, including how many batteries it makes and where, based on demand.

..BUT,… why not state the actual energy density ,..Wh/kg ??
Click to expand...
Samsung SDI states 900 Wh/l, with a claimed 40% improvement from their LIB production. I assume Samsung is talking about the prismatic format, where the 650 Wh/l value actually corresponds to the best that is available on the market today.
 
We've been over this before, but let's do it again. A simple example. Tesla Model S and Model 3 have roughly the same range today. TMS weighs 2068 kg (of which the 100kWh battery pack weighs approx. 480 kg) TM3 weighs 1828 kg. If we reduce the weight of the TMS battery pack by half (we need cells with +500 Wh/kg for this) then the TMS will weigh the same as the TM3 and therefore still need at least 80 kWh of energy for given range which must be installed in the vehicle. The maximum available instalation volume is given by the vehicle category so you always need check the cell volumetric energy density first.

And I would also like to point out the phenomenom when comparing the volumetric energy density of cylindrical and prismatic format at cell level for specific application. The problem is, that you cannot achieve the same assembly efficiency (AE) on pack level with cylindrical cells due to its geometry. Modern battery packs have common AE around 0.35 for cylindrical and 0.5 for prismatic(pouch) format. This means that the cylindrical cells alone use only 35% of the pack volume, where the prismatic cells ca 50 %. So actual value of 800 Wh/l on cell level in cylindrical format is equal to ca 650 Wh/l on cell level in prismatic(pouch) format on pack level. In other words, 900 Wh/l on cell level in a prismatic format would compete with a cylindrical cell with about 1100 Wh/l on cell level in BEV application, so this claim will indeed be a huge improvement.

Sure, but you are ASSUMING they are talking about prismatic cell format,.. and that was not specificaly stated.
900 watt-hours per liter -- a 40% improvement from its lithium-ion cells.

just talking generically about cell chemistry… that is not correct !
so, why not state the Wh/kg for a product when it is obviously known ?
 
Read the article.. no specifics on any particular cell were mentioned, just the fact that they're doing pilot production and should have cells on the market by 2027.

.....

M3P batteries are CATL’s batteries based on a new material system with higher energy density than lithium iron phosphate (LFP) batteries and lower cost than ternary batteries, Wu said at the time."
 

Samsung SDI to Present Essence of Super-Gap Battery Technology at InterBattery 2024​

https://www.samsungsdi.com/sdi-news/3522.html?pageIndex=1&idx=3522&searchCondition=0&searchKeyword=

"Samsung SDI is also slated to unveil its ultra-fast charging technology that reaches 80% charge from 8% in just 9 minutes, an unprecedented feat in the industry.

This feature is made possible by optimizing lithium-ion transfer path and enabling low resistance. The company aims to carry this technology development to a mass-production phase by 2026. This technology is expected to cut charging time significantly compared to P5.

Another technological prowess Samsung SDI will be presenting is its plan to develop and mass-produce a battery solution that lasts more than 20 years by 2029. Such longer battery life, more than double of battery life of products currently available in the market, will be achieved by strengthening durability of materials going into a battery, according to the company's plan.

Samsung SDI will exhibit a prismatic battery form factor where terminal is moved side-way in contrast to conventional top terminal, in order to enhance energy efficiency and cooling efficacy. Another eye-catching concept is cell-to-pack (CTP) technology for prismatic cells. Samsung SDI seeks to show how it reduces the number of components by more than 35% and the weight by 20%, which serves to materialize high energy density and remarkable cost reduction.

Samsung SDI will showcase no thermal propagation technology, a safety feature that prevents propagation of thermal runaway in the event of a fire or an impact, by exhausting high-temperature gas through a vent built in the cells."

Healable Cathode Could Unlock Potential of Solid-state Lithium-sulfur Batteries​

Healable Cathode Could Unlock Potential of Solid-state Lithium-sulfur Batteries

"...a team led by researchers at the UC San Diego Sustainable Power and Energy Center developed a new cathode material: a crystal composed of sulfur and iodine. By inserting iodine molecules into the crystalline sulfur structure, the researchers drastically increased the cathode material’s electrical conductivity by 11 orders of magnitude, making it 100 billion times more conductive than crystals made of sulfur alone.

....

Moreover, the new crystal material possesses a low melting point of 65 degrees Celsius (149 degrees Fahrenheit), which is lower than the temperature of a hot mug of coffee. This means that the cathode can be easily re-melted after the battery is charged to repair the damaged interfaces from cycling. This is an important feature to address the cumulative damage that occurs at the solid-solid interface between the cathode and electrolyte during repeated charging and discharging.
“This sulfur-iodide cathode presents a unique concept for managing some of the main impediments to commercialization of Li-S batteries,” said study co-senior author Shyue Ping Ong, a professor of nanoengineering at the UC San Diego Jacobs School of Engineering. “Iodine disrupts the intermolecular bonds holding sulfur molecules together by just the right amount to lower its melting point to the Goldilocks zone—above room temperature yet low enough for the cathode to be periodically re-healed via melting.”

“The low melting point of our new cathode material makes repairing the interfaces possible, a long sought-after solution for these batteries,” said study co-first author Jianbin Zhou, a former nanoengineering postdoctoral researcher from Liu’s research group. “This new material is an enabling solution for future high energy density solid-state batteries"."
 

Lyten Achieves Manufacturing Milestone; Now Producing Lithium-Sulfur Batteries At Greater Than 90% Yield​


"SAN JOSE, Calif.--(BUSINESS WIRE)--Lyten, a supermaterials application company and the leader in lithium-sulfur battery technology, today announced it is consistently surpassing 90 percent yield from its automated battery production line, confirming the manufacturability of its lithium-sulfur battery utilizing a sulfur cathode and lithium metal anode.

....

The lithium-sulfur manufacturing performance has been achieved utilizing standard lithium-ion manufacturing equipment and processes. The conversion of lithium-ion equipment to produce lithium-sulfur batteries in Lyten’s pilot facility required 6 weeks and less than 2% of the total capital cost. This confirms Lyten’s ability to rapidly scale by converting existing Li-ion gigafactories to lithium-sulfur with minimal cost and time.

“Lyten now has demonstrated that lithium-sulfur can be built in standard cylindrical and pouch formats, can be scaled to automated manufacturing, and can be done on the same equipment and processes already being used around the globe to manufacture legacy lithium-ion,” said Dan Cook, Lyten CEO and Co-Founder. "The result is a significant reduction in the manufacturing scale up risk for a locally sourced, locally manufactured battery that can leapfrog the performance and cost of existing lithium ion and future solid-state batteries.”

....

Lyten’s lithium-sulfur battery contains no nickel, cobalt, manganese, or graphite in the cathode and anode, enabling an entirely locally sourced and manufactured battery. Lyten expects to achieve 98%+ yields at scale and will begin delivering commercial lithium-sulfur cells for non-EV customers in aerospace and government applications in 2024 from its San Jose pilot production facility. Lyten is executing engineering and design, procuring equipment, and evaluating locations to rapidly scale up lithium-sulfur manufacturing to meet growing interest from EV, trucking, space, aerospace, and government customers."
 
Have we got any lab sample reviews of any of these new chemistry batteries???

If a company is actually producing stuff in a factory, and has not provided reviews to sample to aid it's funding, then it must be falst, unless it backed by a multinational company with millions to throw around, i.e. CATL and Samsung.

So, "production starts" is fishy unless the company is backed by a major electronics specialist, else has lab samples seen by good reviewers.
 
Well, it's a thread for PR releases mostly, not announcement of sale. Maybe we could use a new thread about what's available now.
 
A Breakthrough in Solid-State Electrolytes for All-Solid-State Batteries: Twice the Quality with Streamlined Processes

"KERI has pioneered a technology capable of mass-producing these diminutive solid-state electrolytes with heightened ionic conductivity through a simplified process. Contrary to existing practices, where solid-state electrolytes are often large in particle size, necessitating additional processes such as mechanical grinding, KERI’s approach mitigates both time and cost burdens associated with such processes. Additionally, it eliminates the performance degradation of solid-state electrolytes induced by grinding, a significant impediment to their commercialization.

Dr. Park’s team employed microscopic raw materials, such as lithium sulfide, and meticulously controlled the nucleation rate of each material during chemical reactions, resulting in substantially downsized products. This innovative approach enables the production of fine solid-state electrolytes using a straightforward wet synthesis technique, devoid of intricate processes."
 
Chinese EV battery maker EVE Energy in talks to invest £1bn in new UK gigafactory

"The Chinese company is thought to be considering committing an initial £1.2bn to the project, according to the Sunday Times, which first reported the discussions. Subsequent phases of the works are expected to expand the site, which would make it almost twice the size of Nissan’s electric battery factory in Sunderland.

Last year, Tata Group, the owner of Jaguar Land Rover, also made a £4bn pledge to build an electric car battery gigafactory in Britain. The plant, to be sited in Somerset, will bring 4,000 new jobs to the area."


This is great news. This company makes some impressive cells including a 290whr/kg model recently.

Interesting ?….that these companies based in countries with very cheap labour resources and huge local markets,…see some advantage in placing a manufacturing plant in one of the highest cost labour countries in the world.
. Maybe they foresee future issues with shipping bulk quantities of lithium batteries around the world ?
