Tesla’s approach to battery technology keeps it ahead in the EV industry
Tesla’s dominance in the growing electric vehicle (EV) industry is largely attributed to its unique approach to its battery technology. The engineering behind the all-electric car maker’s cylindrical cells speaks for itself in terms of the performance and range achieved, but in a recent interview with a battery technology researcher, a few things detailed about Tesla’s batteries stood out in particular.
Ravindra Kempaiah is a Ph.D. scholar at the University of Illinois Chicago focusing on advanced battery materials for his thesis. In his interview with Tesla owner and host of All Things EV, Sean Mitchell, Kempaiah explained lithium-ion technology in EVs and the primary issues faced in their development. Overall, the biggest challenge is balancing the three main components in battery production: energy density, cost, and cycle life. Increasing one area will significantly impact the other, and the ideal equation is always being sought after. For example, if you increase energy density for higher range and lower cost, the cycle life takes a major hit. If you increase density and life cycle, the battery alone can cost as much as $100k, as described by Kempaiah.
“We always want more range. We always want higher cycle life. We want our batteries to last 15-20 years and the car to go 500 miles, but this is a problem every battery scientist has faced for the last 30 years,” Kempaiah commented in the interview.
Tesla deals with the same balancing act as other battery-electric car makers; however, there are key factors which seem to have kept the company ahead in the industry.
First, Tesla’s choice of cylindrical cells sets it apart from every other electric vehicle on the market. This provides several advantages that drive performance, flexibility, and cost control. Notably, Rivian is also using cylindrical cells, although their vehicles are not yet under production.
Out of the three types of cells available (cylindrical, prismatic, and pouch cells), cylindrical is the most cost-effective to produce. Namely, the cost per kWh is lower in cylindrical cells versus other types. The metallic jacket around the 18650 and 2170 cylindrical cells used in the Tesla Model S/X and Model 3, respectively, acts as scaffolding and provides structural rigidity to the battery. Additionally, in high powered situations, current draw and distribution of power is over the entirety of the battery pack instead of concentrated in a certain section, according to Kempaiah.
Second, Tesla uses a liquid-cooled thermal management system to manage battery temperatures whereas other automakers take a more economical air cooling approach. By adjusting the temperature of the battery pack, Tesla is able to ensure that cells are operating in their most efficient and optimal states, thereby maximizing battery longevity as well as performance. While reducing cost is an important factor in accelerating the growth of the electric vehicle market, Tesla’s investment in thermal management technology provides an upside for owners who may be looking for longevity and long-term affordability of their cars.
Third, Tesla has actively sought to limit the amount of cobalt it uses in its batteries and already uses less of the element than other companies in the Model 3 batteries. The scarcity of cobalt and its mining sources have subjected it to socioeconomic situations that are more than problematic in the United States, i.e., child labor and similar abuses are widespread in its sourcing. With this in mind, Tesla has been working on the question, “Is cobalt really needed?”
Cobalt is used as a cathode in battery technology, and out of all cathode materials available, it has the highest cost both fiscally and politically. Current consensus on battery technology says that without cobalt, the structural integrity and cycle life in batteries is compromised, as described in the interview. However, some recent scientific literature was cited by Kempaiah that indicated higher nickel content limited the impact of cobalt on batteries, possibly removing the need to use it at all. Nickel is more widely available across the globe, which keeps its cost down and mitigates the socioeconomic impacts often associated with resource mining operations. Overall, the discussion between Mitchell and Kempaiah indicated that Tesla can probably go cobalt-free soon, making it less vulnerable to the cobalt industry.
Finally, Tesla takes great care to educate its customers about proper battery maintenance, especially with regard to the negative impact of bad charging habits. Specifically, keeping an electric car battery charged at 100% for long periods degrades the battery very quickly, while keeping charging states within an optimal range will give it a long life. Tesla makes it a point to communicate to customers the importance of battery health on their overall ownership experience and value of their purchase.
When asked for his opinion by Mitchell, Kempaiah attributed the lack of education by other brands as a disconnect between engineering teams and marketing teams. While battery “best practices” are provided to EV customers by all manufacturers, the importance of communicating the true impact of bad charging habits may not be emphasized enough to be included as prominently as it should.
In summary, Tesla is constantly developing the technology in its vehicles, and its particular attention to its batteries looks to have given the company a significant advantage over its competitors. Perhaps other automakers will take a few tips from Tesla in the future, even if it’s as limited as improving communications with customers.

How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies
Tesla has a few paths to limit damage from the elimination of tax credits.

The United States House of Representatives passed President Trump’s “Big Beautiful Bill” by a vote of 215 to 214 on Thursday, effectively bringing an end to many EV subsidy programs, like the $7,500 tax credit, by the end of this year.
The bill will not only eliminate the $7,500 credit on new EV purchases, but also the $4,000 credit given on the purchase of used electric vehicles, and a $1,000 credit on the installation of Level 2 chargers. It will also impact solar subsidies that help generate clean energy in a residential setting.
EVs would also be subject to a $250 road use fee.
🚨 The “Big Beautiful Bill” has been passed in the House, meaning:
1) The EV tax credit is in serious jeopardy. It will likely be eliminated for 2026.
2) EVs will likely have a $250 road use fee
3) $1,000 Level 2 charger credit will also be eliminated pic.twitter.com/Aad41say43— TESLARATI (@Teslarati) May 22, 2025
All of these things sound like negatives — truly because they are. Those who are not in a financial position to buy an EV this year, even with the tax credit, might not be able to afford them in the coming years either, unless manufacturers are able to bring pricing to a level that is more accessible to consumers.
In theory, President Trump’s focus on bringing manufacturing back to America would bring prices down, but it won’t happen overnight. Companies will take many years to completely bring manufacturing and part sourcing to the United States.
However, Tesla could feel some positives from this bill, and it all comes down to timing. Of course, in the long term, it wouldn’t be great for the company, especially if it did not have two things going on right now: a slightly lagging delivery pace and the introduction of affordable models.
Tax Credit Sunsetting Advantage
Sunsetting the $7,500 tax credit means one thing: those who have been in limbo over buying an EV from Tesla are going to have to make a decision on whether they want to buy this year and still have access to the credit, or test their luck and hope for price reductions.
More than likely, those who have been on the fence will be willing to pull the trigger this year, and Tesla will definitely gain some sales from this fact alone. Other automakers will, too.
This could help offset Tesla’s slow start to the year, which has been caused by the changeover of production lines of the Model Y across each of its factories globally.
Affordable Models
Tesla said earlier this year that it will roll out affordable models in the first half of 2025. These cars are expected to be around the $30,000 mark, but the company has not shed any true information on what they will cost.

Ideally, the cars would cost under $30,000 without the EV tax credit, which would be more than accessible for many car buyers in the United States.
The introduction of models that are not in need of a tax credit to be affordable to the masses. This would help offset some of the losses Tesla might feel from cars losing the tax credit.

X clarifies xAI prediction market rumors, hints at future plans
Musk’s AI firm denied rumors of a Kalshi deal but left the door open. Prediction markets + AI could change how we forecast everything.

X dismissed rumors of xAI entering prediction market partnerships. In a recent X post, Elon Musk’s company clarified that xAI had not yet entered formal partnerships in the prediction market.
However, xAI clarification hinted at future exploration in the prediction market, aligning with X’s goal to become an “everything app.” The speculation underscores AI’s potential to reshape predictive analytics.
“Recent speculation about xAI’s involvement in the prediction market space has been circulating. While we’re enthusiastic about the potential of this industry and engaged in various discussions, no formal partnerships have been confirmed to date. Stay tuned!” noted the X team.
X’s statement followed a Tuesday post by Kalshi, hinting at a collaboration with xAI, which was deleted hours later. Kalshi suggested that xAI could leverage AI to analyze X’s news and social media data, enhancing betting decisions on political and economic events.
Bloomberg reported Kalshi aims to use xAI for tailored insights, enabling users to wager on outcomes like Federal Reserve rate changes or elections through derivative contracts.
“There’s deep alignment between prediction markets, social media, and AI. Prediction markets capture what people know — AI scales what people can know,” said Kalshi CEO Tarek Mansour. “This is just the beginning of a long collaboration to unlock the full potential of prediction markets.”
The prediction market industry fits X’s vision to evolve into a comprehensive platform, capitalizing on its trend and news leader role. While xAI’s denial quashes immediate partnership claims, its openness to discussions signals potential interest in prediction markets, where AI could amplify real-time insights.
xAI’s cautious stance reflects its focus on strategic AI development while navigating speculative buzz. As X pursues its “everything app” ambition, prediction markets could enhance its ecosystem, blending social media’s pulse with AI-driven analytics. With no partnerships confirmed, xAI’s future moves may yet redefine how users engage with event-based predictions, positioning it at the forefront of AI innovation.

Elon Musk sends stern warning to Tesla vandals, doubters
Elon Musk sent another warning to vandals that have attacked Tesla for political reasons.

Elon Musk has sent a stern warning to Tesla vandals, doubters, and attackers, who have subjected the company and its owners to political violence through arson and other modes of retaliation.
Over the past few months, Tesla showrooms and vehicles have been hit with numerous attacks from those who have opposed Musk and his political involvement with the Trump Administration. Although Musk has stepped back from his role within government significantly since the start of May, the company is still looked at as a political target.
While the White House has put a clear-cut line on the acts, calling them domestic terrorism and holding those responsible for the damage they have done, there are still numerous and daily instances of keying cars or worse.
Yesterday, Musk continued to send stern warnings to those who oppose Tesla and choose to handle their distaste for the company with violence and vandalism. In a Bloomberg interview at the Qatar Economic Forum, Musk was asked if he took what has happened to Tesla “over the past few months personally.”
Musk replied simply but sternly: “Yes.”
“Did you take what happened to Tesla over the past few months personally?”
“Yes.” –@elonmusk pic.twitter.com/mNbgkpgZEo

He went on to say that not only will those who vandalized the company and its products owned by consumers be held to the fullest extent of the law, but also those who fund it.
Musk also said during a CNBC interview yesterday that very few people buy a company’s products because of the CEO’s political beliefs, and many people do not even know where those CEOs stand on various social issues.
Although Musk has gone out of his way to be transparent about his beliefs, he has a valid point. He obviously felt that, because of his influence, he held a duty to uphold American values and protect what he felt was an attack on free speech and human rights.
Disagreeing with Musk and his political stances is totally reasonable, but damaging products that consumers bought from his companies is not impacting him directly. Instead, it is making consumers’ lives more difficult.
