A newly released patent from Tesla has teased what appears to be a step towards Elon Musk’s one-million-mile battery target. The patent describes a new lithiation process for battery cells, which has the potential to improve the quality of cells and possibly even save on costs.

Tesla has submitted a patent titled “Method for Synthesizing Nickel-Cobalt-Aluminum Electrodes.” The document outlines a new electrode synthesizing method that could be used for battery cell production. The proposed application defines an efficient heating process for Nickel-Cobalt-Aluminum (NCA) electrodes. According to the document, previous heating methods at times cause the formation of a lithium substrate known as L15AIO4, which is an impurity. Lowering the amount of lithium within a battery reduces the presence of the contamination, but also leads to “materials with inferior electrochemical properties.”

As noted in the patent, batteries would heat to a temperature high enough to allow for single crystal growth. The revised ratio of lithium to other metals would limit the formation of impurities during the first heating process. Then, the battery would be heated a second time at a temperature lower than the first heating cycle. Researchers involved in the patent noted that this process helped develop an impurity-free single crystal NCA that allowed battery cells to achieve over 4,000 charge cycles.

The patent outlines the heating process:

“Methods disclosed herein include a first lithiation step, wherein a lithium and an other metal component are present in a first lithium/other metal ratio of less than 1.0 and are sintered at a temperature between 800 and 950°C for a time period between 1 and 24 hours to obtain a first lithiated material. The method further includes a second lithiation step, wherein a lithium and a other metal component are present in a second lithium/other metal ratio and further wherein the first lithiated electrode material is sintered with additional LiOHTLO at between 650 and 760°C for a time period between 1 and 24 hours to obtain a second lithiated material.”

In summary, the use of NCA electrodes in batteries would allow for single-crystal materials to present themselves without impurities. The lack of contaminants could lead to an increased lifespan of the cells altogether, helping Tesla take a giant leap forward in its quest to produce a one-million-mile battery for its vehicles.

Interestingly enough, one of the listed names on the patent is battery expert and researcher Jeff Dahn, who has worked with Tesla in the past. Tesla summoned the help of Dahn, who leads a team of researchers at Canada’s Dalhousie University, to help the electric car maker improve its batteries. Dahn’s research has helped Tesla’s development of high-quality battery cells by inventing new electrode combinations, like the one described in this patent, and electrolyte solutions aimed at further increasing battery life.

Tesla’s batteries are always in a state of improvement, and over the years, the cells that the company utilizes for its vehicles and energy storage systems have gotten more energy-dense. Economies of scale that is made possible with facilities such as Gigafactory Nevada have also gone a long way towards helping Tesla near the $100 per kWh mark, a level that is widely considered the point where electric vehicles could achieve price parity with their internal combustion-powered counterparts.

Apart from its battery patents, Tesla has also been busy acquiring several battery companies. Among these are Maxwell Technologies and Hibar Systems, both of which were developing technologies that would allow for better battery quality and more efficient production costs. Relatively simple developments such as those described in Tesla’s recent patent help this cause too, especially since every little bit of optimization helps.

Tesla’s development of its battery technology could lead to its vehicles lasting 20 to 30 years, far longer than petrol-powered cars. It appears the company is planning to create a product line that could stay with owners for extended periods with relatively no annual maintenance. And that, together with price parity, can very well be the catalyst for society’s acceleration towards sustainability.

Florida man charged after trying to hit Tesla protestors with car

A man in Florida has been charged with assault after attempting to drive into protestors outside of a Tesla store over the weekend, coming as the latest in ongoing protests and vandalism against CEO Elon Musk.

On Saturday, 44-year-old Andrew Tutil attempted to drive into protestors with his Nissan Pathfinder at the West Palm Beach Tesla store, although no one was injured, according to a report from Palm Beach Daily News. The store had around 150 protestors outside around 1:00 p.m., and Tutil reportedly drove slowly into the crowd before parking on the sidewalk and getting out.

“He drove into a crowd of senior citizens,” said Mark Offerman. “Everybody was able to move out, but two older women were really almost clipped. We immediately called the cops.”

After parking on the sidewalk where protestors had to jump out of the way, Tutil, a retired U.S. Army Captain, civil engineer, and supporter of Donald Trump, claimed that he was an employee of the Tesla store and that his brakes and electronics had malfunctioned, according to Offerman.

Palm Beach County records show that Tutil was later arrested and charged with first-degree felony aggravated assault with a deadly weapon without intent after police questioned Tutil and surrounding witnesses and reviewed photos and video footage.

The news comes as a wave of protests, acts of vandalism, and some violent encounters such as this one have been increasingly targeting Tesla stores in recent weeks against Musk and the Trump administration. Additionally, Musk’s work with Trump’s newly created “government efficiency” division has been a central theme in protests at Tesla stores, as federal workers have expressed criticism for the administration’s approach to “eliminating fraud and waste.”

The widespread protests began in January, after Musk performed what many said looked like a Nazi salute at Trump’s inauguration ceremony, and after he spoke at a campaign event for the far-right German party Alternative for Germany (AfD). During the rally, Musk said that there was “too much of a focus on past guilt and we need to move beyond that,” which many claimed was in reference to Nazi Germany.

The so-called “Tesla Takedown” movement launched over the past several weeks is targeting around 500 separate protests across 277 stores around the U.S. The Palm Beach protest on Saturday was just one of a handful in Florida alone, including those in Gainesville, Jacksonville, Merrit Island, and Sarasota, to name a few.

One protestor at a Tesla store in Colorado earlier this month told Teslarati that she was protesting Musk because she was “highly concerned that our Constitution is being ignored,” adding that “it’s dangerous to have power rest in a handful of ultra-wealthy people.”

Others at the event highlighted Musk and Trump’s attacks on queer, trans, and non-binary people, as well as the administration’s recent controversies with Ukraine President Volodymyr Zelenskyy, and claims that the President is aligning with Russia President Vladimir Putin, as a few of the major reasons they were protesting at the Loveland Tesla store.

Musk has mostly deflected and made light of claims of his alignment with Nazis, while the public has been polarized on defending or condemning these and other actions.

The Tesla CEO was defended by Israel Prime Minister Benjamin Netanyahu, who said he was being “falsely smeared” immediately following the inauguration event. While the Anti-Defamation League (ADL) also went on to defend the action as an “awkward gesture,” the group has since condemned some of Musk’s more recent posts making light of genocide.

Earlier this month, Musk reposted then deleted a screenshot shared by X user Rothmus claiming that “Stalin, Mao and Hitler didn’t murder millions of people,” but that “their public sector workers did.”

“It is deeply disturbing and irresponsible for someone with a large public platform to elevate the kind of rhetoric that serves to undermine the seriousness of these issues,” the ADL wrote in a response on X.

In addition to what have largely appeared to be peaceful protests at Tesla stores, a number of acts of vandalism, including graffiti, arson, and some even more violent assaults involving weapons, have been targeting the automaker’s locations around the world.

Multiple people were taken into custody following repeated arson and graffiti at a Tesla store in Colorado within the past few weeks, while multiple Tesla vehicles have been set on fire at stores, and one Tesla store has been shot at. Owners of Tesla’s vehicles have also been targeted in public, with some being captured on Sentry Mode keying or tagging the vehicles.

The Trump administration has also started labeling such attacks against Tesla as “domestic terrorism,” and the Federal Bureau of Investigation (FBI) has started investigating several of the events, including one involving two Cybertrucks that were set on fire in Seattle and another at a store in Oregon that was shot at twice in a few weeks.

Partners involved in yet another Tesla Megapack project in Australia have reached a financial close, as the upcoming site also begins construction.

On Monday, renewables provider Equis Australia announced closing on the $260 million deal for 138 two-hour Megapack units in Tamworth, New South Wales (NSW), set to back a 250MW/500MWh battery energy storage system (BESS). Dubbed the “Calala” BESS, Equis says the project will store enough power to supply electricity for as many as 115,000 homes during peak usage.

The Calala project is expected to become fully operational by 2027, and it will be constructed in two independent project phases, bringing 100MW and an additional 150MW online in sequence. Located about 5.8 kilometers (~3.6 miles) to the southeast of the Tamworth town centre, the Calala battery will be connected to the NSW grid using an underground cable leading to Tamworth’s 330kV Substation.

The BESS is also expected to create around 170 new roles during construction, and as many as seven ongoing positions upon launching operations. The first 100MW portion of the Calala project will be devoted to supplying a partnership with provider Smartest Energy, while Tesla’s Autobidder real-time trading and control platform will be used to manage and oversee energy transactions to make the 150MW project a merchant BESS.

The financial deal includes the sale of $260 million in non-recourse debt financing package from lenders Westpac, Societe Generale, and the Sumitomo Mitsui Banking Corporation. The agreement will also include a Voluntary Planning Agreement (VPA) for the Calala project to contribute a total of $2 million to the Tamworth Regional Council over time.

Equis Australia also has several other BESS projects, primarily located near its headquarters in Melbourne, along with those scattered around the Sydney and Brisbane areas. The company’s Australia branch says it has 16 BESS projects in its portfolio, along with 11 onshore wind projects, together which total 9.6GW of renewable energy capacity.

The renewable provider is also nearing completion of a massive 600MW/1,600MWh BESS outside of Melbourne sporting 444 Tesla Megapack units, which is expected to become operational later this year.

Currently, Tesla produces most of its Megapacks in Lathrop, California, though the company recently shipped its first units from a new Megafactory in Shanghai, China to Australia. The manufacturer has also begun building a third Megafactory in Waller County, Texas, just a couple of hours east of Tesla’s Gigafactory Texas.

Tesla Model Y inventory is going fast, selling out in many U.S. states

Tesla Model Y inventory is apparently moving pretty quickly as the legacy version of the best-selling car in the world is now sold out in many U.S. states.

With the introduction of the new Tesla Model Y, the legacy version of the vehicle is now no longer being produced. The units that are available are the final ones that Tesla will produce as it is sunsetting the old look of the all-electric crossover.

As production has stopped on this specific version of the Model Y, Tesla is offering some great deals on the vehicle…that is, if it is still available for delivery in your area.

Since the new Model Y has started production and deliveries, 29 U.S. states have now sold out of the old vehicle’s look:

Tesla is offering over $5,000 off of some of these Model Ys in an effort to move inventory and make room for the new Model Y at its showrooms across the country.

For what it is worth, the legacy Model Y is still a fantastic vehicle, and picking it up through inventory is still a great idea, considering it holds a lot of great tech and is now being offered at a great price.

In the United States, Tesla is still only offering the new Launch Series version of the Model Y, which comes with the company’s Full Self-Driving suite, some exclusive badging, and premium interior, among other things.

Until those lower-cost trims arrive, sales figures for the new Model Y will be restricted to the Launch Series trim. We likely won’t see a launch of Rear-Wheel-Drive or All-Wheel-Drive configurations of the new Model Y until the inventory of the previous version starts to dwindle down a tad more.

Launching those trims now would cannibalize the legacy Model Y vehicles, as most consumers would rather have the new vehicle with the upgrades than the older version — even if it means a substantially lower price.
