Tesla has made a lot of battery moves this year and it is closing the year by filing a patent on a new chemistry for better, longer-lasting and cheaper batteries.
Earlier this year, we reported on Tesla’s battery research partner, Jeff Dahn and his team at Dalhousie University, unveiling the impressive results of tests on a new battery cell that could last over 1 million miles in an electric vehicle.
The new battery tested is a Li-Ion battery cell with a next-generation “single crystal” NMC cathode and a new advanced electrolyte.
Since then, Tesla has been filing US and international patents on the new battery chemistry.
The automaker, through its ‘Tesla Motors Canada’ subsidiary, filed a new international patent called ‘Dioxazolones and nitrile sulfites as electrolyte additives for lithium-ion batteries’.
They wrote in the patent application:
“This disclosure covers novel battery systems with fewer operative, electrolyte additives that may be used in different energy storage applications, for example, in vehicle and grid-storage. More specifically, this disclosure includes additive electrolyte systems that enhance performance and lifetime of lithium-ion batteries, while reducing costs from other systems that rely on more or other additives.”
Tesla wrote in the conclusion of the patent application for the new battery chemistry:
“This work characterizes the high temperature storage and long-term cycling performance of lithium-ion NMC/graphite pouch cells prepared with a recently developed electrolyte additive, MDO, and two new additives, PDO and BS. Differential capacity versus voltage indicates that both MDO and PDO form passive SEI layers on the graphite electrode surface during cell formation, whereas BS does not. The reduction features are generally consistent with DFT-predicted values, although the presence of multiple reduction peaks requires additional study to rationalize. As individual additives, PDO-containing cells show the best performance although these are nonetheless out-performed by VC-containing cells. The additives were also tested in binary blends with VC, DTD, and LFO. In long-term cycling tests, cells prepared with 2%PDO/l%DTD and 2%PDO/l%LFO additive blends outperform VC-containing cells. However, the high temperature storage behavior of 2%PDO/l%LFO is superior than that of the 2%PDO/l%DTD blend. A person of skill in the art will understand that compositions described herein may be further optimized, for example, by adjusting the ratio of primary and secondary additives or through introducing ternary blends.”
The patent application says that the new two-additive mixtures in an electrolyte solvent can be used with lithium nickel manganese cobalt compounds, also known as an NMC battery chemistry.
It is commonly used in electric vehicles by many automakers, but not by Tesla. The company used the technology in its stationary energy storage systems, but it uses NCA for its vehicle battery cells.
The patent filed by Tesla’s battery research group mentions that the technology would be useful for both electric vehicles and grid-storage.
Tesla has been filing new battery patents as it has also been making moves toward building its own battery cells.
Earlier this year, Tesla CEO Elon Musk said that they built Model 3 to last as long as a commercial truck, a million miles, and the battery modules should last between 300,000 miles and 500,000 miles.
However, the CEO claimed that Tesla has a new battery coming up next year that will last a million miles.

Everything We Expect at Samsung Unpacked, From Galaxy Z Fold 4 to Galaxy Watch 5 – CNET
Samsung’s next Galaxy Unpacked event. We expect to see several new versions of the company’s and smartwatches to be revealed — but there’s always a chance for surprise launches of new devices.
The event invitation seen above, showing a Z Flip foldable phone, suggests we’ll see new versions of Samsung’s foldables. That fits with afrom tipster Evan Blass predicting new versions of the and the clamshell which came out in August 2021.
Don’t expect too many big advances with Samsung’s next foldables. Rumors suggest the tablet-sizemay have a new hinge and slimmer build, but the leaker jury is out on whether it will include an S Pen slot like the . Other rumors predict that the foldable will pack the faster Snapdragon 8 Gen 1 Plus chipset, as well as a larger outer display that requires its own under-display camera to complement the one on the inner screen.
The makeup compact-lookingcould get a larger cover display, according to other rumors, which could make it far more useful for reading notifications and previewing selfie photos.
Even if the new foldables have only incremental spec upgrades, the biggest improvement could be price. Thewas cheaper than its predecessor at $1,800 (£1,599, AU$2,499) to start, which is still around twice as expensive as most premium smartphones. The shockingly came in at $1,000 (£949, AU$1,499), or around the price of an iPhone 13 Pro, making it the most affordable foldable yet and a viable alternative to standard flat smartphones.
But the upcoming Z Fold 4 and Z Flip 4 could be even cheaper, predicts analyst Ross Young, CEO of Display Supply Chain Consultants, who tweeted that Samsung ramped up production to churn out twice as many of the new foldables as last year’s models, suggesting a possible price cut.
In any case, we expect the new foldables to sell well, since the Z Fold 3 and Z Flip 3than were sold in all of 2020. With 88% of the more than 7 million foldables sold in 2021, Samsung is in a strong position to continue dominating the niche foldable market, which is to over 27 million sold in 2025.
Samsung could launch other products to accompany the foldables, and the most likely is the. Rumors predict the next version of the premium smartwatch line could get a body temperature sensor and better battery life, as well as an updated design. Hopefully, it will also fix a glaring flaw in the — no support for iPhones — as well as better integration of Wear OS 3, as we felt last year’s watch pulled between .
There are other things Samsung could show off, like successors to theearbud, tablets or laptops, but we haven’t heard many rumors suggesting any of those are likely to arrive. Still, we could easily be surprised with all eyes on the awaited foldables.
To encourage customers to reserve their phones early, from July 19 until August 10,based on different bundles, from a maximum of $200 off for those reserving a Galaxy phone, watch, and buds down to a minimum of $30 off for just reserving Galaxy buds. While this could be a hint at what’s coming at Unpacked, the savings could apply to older Galaxy Watch or Galaxy Buds models.
The event is scheduled to begin at 9 a.m. ET / 6 a.m. PT. CNET will be watching and covering the reveals.
