Tesla patents new chemistry for better, longer-lasting and cheaper batteries – Electrek
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.
Interestingly, Tesla has been rumored to be switching to NCM battery cells for Chinese Model 3 vehicles.
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.
Here’s Tesla’s full patent application:

MSPs require tools that enable them to provide a comprehensive managed services experience, which means having one platform with all of the essential productivity, data availability, and security tools combined into an easy-to-use package.
This is one of the many pros of MSPs, as they can offer a one-stop shop for all of your IT needs.
Cybersecurity and emerging technology, including automation, are major trends for MSPs who look forward to the future. In coming research briefs we’ll address these topics more in-depth.
- Reliability
Opting for the appropriate managed service provider (MSP) for your business is a critical decision, which has far-reaching effects on daily operations. Finding a partner that is reliable and can meet all of its IT needs is essential to meeting those objectives successfully.
A reliable MSP will conduct an intensive assessment of your company’s infrastructure and processes to fully comprehend your IT requirements, offering services that best suit them for data plans, telecom options, business applications, and hardware needs.
MSPs also provide 24/7 monitoring and support, meaning if a problem does arise it can be handled instantly compared to waiting for assistance from an overburdened in-house tech team. This ensures consistent service, reducing downtime and lost revenue as a result.
- Scalability
As an MSP, your goal should be to expand the services you offer and increase revenue – whether that means expanding customer bases or adding innovative technologies.
But it is also essential to bear in mind that not all changes are scalable; some could impede on your business’s efficiency, leading to more expenses than profits – this phenomenon is known as diseconomies of scale, and it could spell doom for your enterprise.
Implementing new software solutions such as Tanium may require upgrading your infrastructure, which takes time and money. Working with an experienced IT partner is highly recommended to ensure that any upgrades made are scalable – they have evaluated many solutions that may work for your business and know which are ideal.
- Security
MSP companies can provide businesses with essential cybersecurity services that will assist in maintaining security. MSP companies can assist businesses with software deployment, patch management and configuration control as well as the creation and implementation of an unified threat detection and response platform to detect evolving threats.
An MSP can be an invaluable asset to smaller businesses with limited IT resources, but it must balance client needs against budgetary limitations and the risk of cyber breaches.
Customers should review MSP contracts carefully to ensure they provide adequate security measures, limit attack surface by enforcing multifactor authentication (MFA) on all accounts, and track unexplained failures in authentication. In addition, it’s wise to regularly review and delete MSP accounts when they’re no longer managing infrastructure.
- Flexibility
An outstanding MSP provides more than just scalability; they also have the flexibility needed to help clients find solutions tailored specifically to meet business needs and budget constraints, helping to avoid costly organizational downtime.
Working from home and cloud management are driving managed services market growth well past 2020, so MSPs that offer their clients access to tools and support will be well positioned to capitalize on this market shift and remain profitable long term.
An MSP that can offer additional services will also be able to reduce customer churn and boost its revenue per client, such as IT strategy consulting or backup and recovery solutions.
- Efficiency
MSPs offer many businesses an efficient and cost-effective method for handling IT. Their services tend to be much cheaper than what it would cost an enterprise to implement and manage on their own, and provide more flexibility and scalability than when the task falls on them alone.
MSPs typically specialize in specific aspects of technology or vendor management, enabling them to provide more effective IT solutions than an in-house team could. A good MSP also serves as a single point of contact and becomes familiar with their client’s business over time.
Outsourcing certain technology functions to a Canadian IT company can also lower overhead costs by freeing up internal employees to focus more on revenue-generating activities, leading to greater productivity and efficiency within a company.

(Bloomberg) — Video-game tool maker Unity Software Inc. said Monday it’s backtracking on major aspects of a controversial new price hike, telling staff in an all-hands meeting that it’s now considering changes including a cap on potential fees.
Unity, which operates and licenses a suite of video-game development tools called the Unity Engine, set off a firestorm last week when it announced plans to charge customers for every new installation of their game after a certain threshold. The decision triggered widespread protests, leading several video-game makers to say they would boycott Unity until the policy is changed.
Under the tentative new plan, Unity will limit fees to 4% of a game’s revenue for customers making over $1 million and said that installations counted toward reaching the threshold won’t be retroactive, according to recording of the meeting reviewed by Bloomberg. Last week, Chief Executive Officer John Riccitiello delayed an all-hands meeting on the pricing changes and closed two offices after the company received what it said was a credible death threat.
The company apologized to customers on Sunday and said it would be making changes to the pricing policy.
Marc Whitten, a Unity executive, said the company hasn’t yet announced the latest changes because executives are still running them by partners and don’t want to repeat last week’s communications debacle, which led to several clarifications.
One of the most controversial elements of the policy concerned how Unity would track installations of its software. Although the company first said it would use proprietary tools, Whitten said Monday management will rely on users to self-report the data.
In the meeting, Riccitiello emphasized that the new policy is designed to generate more revenue from the company’s biggest customers and that more than 90% of Unity users won’t be affected. Several employees asked during the meeting how Unity would bounce back from what appeared to be a breach of trust. Executives said the company will have to “show, not tell” and handle future communications more carefully.
“I don’t think there’s any version of this that would have gone down a whole lot differently than what happened,” Riccitiello said. “It is a massively transformational change to our business model.”
But, he acknowledged, “I think we could have done a lot of things a lot better.”
