Tesla's Secret Batteries Said to Aim to Rework the Math for Electric Cars and the Grid

Tesla’s Secret Batteries Said to Aim to Rework the Math for Electric Cars and the Grid

Electric car maker Tesla plans to introduce a brand new low-cost, long-life battery in its Model 3 sedan in China later this year or early next year. the company expects that it will bring the cost of electric vehicles in line with gasoline models, and permit EV batteries to have second and third lives in the electric power grid.

For months, Tesla Chief Executive Elon Musk has been teasing investors, and rivals, with promises to reveal significant advances in battery technology during a “Battery Day” in late May.

New, low-cost batteries designed to last for 1,000,000 miles of use and enable electric Teslas to sell profitably for a similar price or less than a gasoline vehicle are just part of Musk’s agenda, people familiar with the plans told Reuters.

With a worldwide fleet of over 1 million electric vehicles that are capable of connecting to and sharing power with the grid, Tesla’s goal is to attain the status of a power company, competing with such traditional energy providers as Pacific Gas & Electric and Tokyo electric power, those sources said.

The new “Million-Mile” battery in the middle of Tesla’s strategy was jointly developed with China’s Contemporary Amperex Technology Ltd (CATL) and deploys technology developed by Tesla together with a team of academic battery experts recruited by Musk, three people familiar with the hassle said.

Eventually, improved versions of the battery, with greater energy density and storage capacity and even lower cost, are going to be introduced in additional Tesla vehicles in other markets, including North America, the sources said.

Tesla’s decision to launch the new battery first in China and it’s a broader strategy to reposition the company has not previously been reported. Tesla declined to comment.

Tesla’s new batteries will consider innovations like low-cobalt and cobalt-free battery chemistries, and the use of chemical additives, materials, and coatings that will reduce internal stress and enable batteries to store more energy for longer periods, sources said.

Tesla also plans to implement new high-speed, heavily automated battery manufacturing processes designed to reduce labor costs and increase production in massive “Terafactories” about 30 times the size of the company’s sprawling Nevada “Gigafactory” — a technique telegraphed in late April to analysts by Musk.

Tesla is working on recycling and recovery of such expensive metals as nickel, cobalt, and lithium, through its Redwood Materials affiliate, also as new “second life” applications of electric vehicle batteries in grid storage systems, like the one Tesla in-built south Australia in 2017. The automaker also has said it wants to supply electricity to consumers and businesses but has not provided details.

Reuters reported exclusively in February that Tesla was in advanced talks to use CATL’s lithium iron phosphate batteries, which use no cobalt, the most expensive metal in EV batteries.

CATL also has developed a less complicated and less expensive way of packaging battery cells, called cell-to-pack, that eliminates the middle step of bundling cells. Tesla is predicted to use technology to help reduce battery weight and price.

The sources said CATL also plans to provide Tesla in China next year with an improved long-life nickel-manganese-cobalt (NMC) battery whose cathode is 50 percent nickel and only 20 percent cobalt.

Tesla now jointly produces nickel-cobalt-aluminum (NCA) batteries with Panasonic at a “Gigafactory” in Nevada and buys NMC batteries from LG Chem in China. Panasonic declined to comment.

Taken together, the advances in battery technology, the strategy of expanding the ways in which EV batteries will be used and the manufacturing automation on a huge scale all aim at the same target: Reworking the financial math that thus far has made buying an electric car costlier for most consumers than sticking with carbon-emitting internal combustion vehicles.

“We’ve ought to really ensure we get a very steep ramp in battery production and continue to improve the cost per kilowatt-hour of the batteries — this is very fundamental and very difficult,” Musk told investors in January. “We’ve got to scale battery production to crazy levels that individuals cannot even fathom today.”

Tesla has reported operating profits for three quarters in a row, driving a near-doubling of its share price this year. Still, Musk’s ambitious expansion plans depend upon increasing both profit margins and sales volume.

A number of the technical advances made by Tesla and CATL in battery chemistry and design originated at a small research laboratory at Dalhousie University in Halifax, Nova Scotia. The lab has been run since 1996 by Jeff Dahn, a pioneer in the development of lithium-ion batteries for electric vehicles and grid storage.

Dahn and his team began an exclusive five-year research partnership with Tesla in mid-2016, but the relationship dates back at least to 2012.

Among the critical contributions from Dahn’s lab: Chemical additives and nano-engineered materials to built lithium-ion batteries tougher and more resistant to bruising from stress like rapid charging, thus extending their life.

The cost of CATL’s cobalt-free lithium iron phosphate battery packs has fallen below $80 (Around Rs. 6,000) per kilowatt-hour, with the price of the battery cells dropping below $60/kWh, the sources said. CATL’s low-cobalt NMC battery packs are near to $100/kWh (roughly Rs. 7,550).

Auto industry executives have said $100/kWh (roughly Rs. 7,550) for battery packs is the level at which electric vehicles reach rough parity with combustion competitors.

Battery expert Shirley Meng, a professor at the University of California San Diego, said NMC cells could cost as little as $80/kWh (roughly Rs. 6,000) once recycling and recovery of key materials like cobalt and nickel is factored in. Iron phosphate batteries, which are safer than NMC, could find a second life in stationary grid storage systems, reducing the upfront cost of these batteries for electric vehicle buyers.

In comparison, the new low-cobalt batteries being jointly developed by General Motors and LG Chem are not expected to succeed in those cost levels until 2025, according to a source conversant in the companies’ work.

GM declined to discuss its cost targets. Earlier this year, it said only that it planned to “drive battery cell costs below $100/kWh” without specifying a timetable.

OnePlus 9 borrows from OnePlus 8 Pro a lot, hints latest leak

OnePlus 9 borrows from OnePlus 8 Pro a lot, hints latest leak

What do we know about OnePlus 9? For starters, it is bound to run on the Snapdragon 888 chip and is most likely to be an evolution of the OnePlus 8T. That’s it! Most of the leaks on the OnePlus 9 series are related to the OnePlus 9 Lite, a new addition to the lineup that’s speculated to keep the flagship range fairly accessible to consumers. For those not caring about accessibility, the vanilla model may be the sweet one to choose since it borrows from the OnePlus 8 Pro a lot if the latest leaks are anything to believe.



A report from 91Mobiles has leaked some of the details on the upcoming OnePlus 9 and while the main details are yet to come out, there’s enough to get OnePlus fans excited. The regular model is likely to get borrow some features from the OnePlus 8 Pro, such as wireless charging, reverse wireless charging, and a 65W fast-charging system charging the 4500mAh battery. For power users, these additions should be enough to consider the next-gen upgrade.

OnePlus 9 going high on its wireless ambitions

In 2020, OnePlus introduced the concept of wireless charging to its Pro variant of the OnePlus 8. The phone grabbed headlines for its 30W fast wireless chargings system, which promised a full top-up in almost an hour. OnePlus retained the feature for the Pro model as the newer OnePlus 8T skipped the wireless charging feature entirely and focused on the 65W fast charging system. With Apple embracing wireless charging better with the iPhone 12, OnePlus seems to be following the same for most of its devices.



Another notable upgrade seems to be the 4500mAh battery over the 4300mAh unit from the OnePlus 8. Surely, it’s not drastically bigger but even a minor increase in battery capacity is always helpful. The phone is also said to retain the flat display from the OnePlus 8T, complete with a punch-hole cutout in the corner.

Previous leaks and rumors hinted at a possible upgrade to the main camera system on the regular OnePlus 9 since it last saw an upgrade in 2019 with the OnePlus 7. The main camera is said to use the 50-megapixel Sony IMX766 sensor that just debuted on the Oppo Reno 5 Pro+. This could be accompanied by a 20-megapixel ultra-wide camera and a 12-megapixel telephoto camera system. After the OnePlus 7T, this is the first time since the cameras would be upgraded on the regular model if these rumors are true.

What remains to be seen is what will the OnePlus 9 Pro bring to the table? Speculations suggest the same curved edge display design mated to a new camera system, the new Snapdragon 888 chip, an even bigger battery, and possibly, the 120W fast wired charging from those Oppo flagships.

Samsung removes ad that mocked Apple for charger-less iPhone 12 and we know why

samsung note 20 ultra

Samsung seems to have a habit of poking fun at its direct competitor Apple for whatever the latter does. This happened when Apple removed the 3.5mm audio jack or when it introduced the notch in the iPhone X, and even recently when Apple stopped selling a charger with the new iPhone 12 series and more to follow. But now, the South Korean tech major has removed the recent ad that mocked Apple for this reason and we may know why.

Samsung gets rid of ad that mocked Apple

The company has removed the advert that its Caribbean subsidiary posted after Apple launched the iPhone 12. The ad threw a jab at Apple’s decision to not include the charger and the EarPods with the iPhone 12 series and more iPhones to follow.



The ad posted on Facebook with a black charger, which no longer exists, by the way, read, “Your #Galaxy does give you what you are looking for. From the most basic as a charger to the best camera, battery, performance, memory, and even 120Hz screen on a phone.

While Samsung hasn’t revealed why it removed the ad, the reason is deemed pretty simple. Much like earlier, the company will also follow Apple and remove the charger and earphones with the upcoming Samsung devices.

For those who don’t know, Samsung has taken jabs at Apple on several occasions. It mocked Apple for the removal of headphones jacks, inclusion of notches, non-inclusion of fast charging, and even for the apparent lower download speeds.

While the company leaves no stone unturned to poke fun at Apple and keeps on coming up with indirect ways to do it, the company eventually ends up following what Apple has done. This leaves us wondering why the mockery in the first place.



For the uninitiated, Samsung is also expected to remove the in-box charger and earphones with the Samsung Galaxy S21 series, which is scheduled to launch in January 2021. The decision, which is for environmental reasons (at least on the surface) will take shape in Europe and eventually extend to more regions.

However, we still don’t have a confirmation on the same and need to wait until the launch to take place.

galaxy tab active 3

There are only a couple of companies that sell Android tablets in 2020. The notable two brands are Samsung and Huawei. The South Korean tech giant had only recently launched Galaxy Tab S7 and Galaxy Tab S7+ as its flagship tablet devices. Now, it seems the corporate will soon release Galaxy Tab Active 3 whose entire specs are now leaked.



The upcoming Galaxy Tab Active 3 will be the successor to Galaxy Tab Active 2 from late 2017. Samsung’s Active series of tablets are targeted at industries, hence the long interval of 3 years between the launch of every new model. For those unaware, the primary one in the series was unveiled back in December 2014.

That said, the 2020 model was first spotted on Geekbench with model number SM-T575 in July powered by Exynos 9810 paired with 4GB RAM and Android 10 operating system. Just in case you’re wondering, this chipset made its debut inside Galaxy S9 in 2018.



Now, an exclusive leak by SamMobile reveals the other remaining specs of this forthcoming Galaxy Tab Active 3. As per the publication, it’ll be MIL-STD 810 certified for durability and can be available in 64GB and 128GB storage configurations. Customers will also have a choice to get it with LTE connectivity.

Further, on the front, the tablet will sport an 8-inch TFT LCD panel with a resolution of 1920×1200 pixels and three physical buttons below it for navigation as per the SafetyKorea certification bureau. It might come with Bluetooth 5.0 and can also support S Pen with remote control option.

Last but not least, it’ll be backed by a 5,050mAh battery and its launch date is not known at this point. Anyway, since its a niche product, we expect Samsung to announce it via press release within the coming days just like the Galaxy S20 Tactical Edition.
