StoreDot has managed to prove that it can “winterproof” its extreme fast-charging electric vehicle batteries, new laboratory testing showed.
StoreDot is a company out of Israel that is aiming to increase fast-charging capabilities in its EV battery cells, while also increasing the overall lifecycle and promoting more groundbreaking advancements in batteries that will be used in electric cars.
Tesla examining StoreDot’s XFC Extreme Fast Charging batteries: report
The company recently put its silicon battery cells to the test against cold weather, which has been one of the biggest challenges EV makers have faced in recent years. EV companies have seen their vehicles’ expected range diminish in cold weather conditions, and while some automakers have used a variety of strategies to combat this issue, it still remains prevalent.
StoreDot’s testing showed that its battery cells reached an 80 percent capacity when charged at -10ºC, or 14ºF, when charged at standard speed. However, they have also been tested to show a consistent discharge rate and an adequate driving range in these same temperatures.
In fact, the cells “delivered over 85% of their full range capacity. Even in the extreme cold of -4°F (-20°C), the cells still provided over 70% of their full range capacity,” the company said.
“Our latest tests have demonstrated that our batteries can outperform traditional cold weather range and charging limitations that often hamper electric vehicles in colder climates,” StoreDot CEO Dr. Doron Myersdorf said.

“Although all lithium-ion batteries tend to lose capacity in extreme cold, our innovative design that uses silicon-dominant anodes minimizes this loss. Our batteries deliver optimal driving range even in most extreme, subzero conditions. With our revolutionary technology drivers can now conquer winter’s toughest challenges, ensuring a smooth driving experience in any climate or conditions and eliminating winter range anxiety.”
A test from Consumer Reports from January showed that cold weather is able to essentially diminish a much higher percentage of the range than what StoreDot’s testing did.
The test from CR showed cold weather essentially deletes about 25 percent of range when driving at 70 MPH. However, in short trips in the cold that usually include frequent stops, it can be as much as 50 percent.

Waymo temporarily halts service in select San Francisco and LA areas amid protests
The suspensions came after several Waymo Jaguar I-Pace robotaxis were vandalized and set ablaze during the demonstrations.

Waymo, Alphabet’s autonomous vehicle subsidiary, has suspended its driverless taxi operations in parts of Los Angeles and San Francisco amid violent protests linked to U.S. Immigration and Customs Enforcement (ICE) raids in the state.
The suspensions came after several Waymo Jaguar I-Pace robotaxis were vandalized and set ablaze during the demonstrations.
Waymo Catches Strays Amid Anti-ICE Protests
Protests erupted in Los Angeles and San Francisco in response to the Trump administration’s immigration raids, which ultimately resulted in California Governor Gavin Newsom calling the White House’s deployment of National Guard troops unconstitutional.
Amidst the protests, images and videos emerged showing several Waymo robotaxis being defaced and destroyed. At least five Waymo robotaxis ended up being caught in the crossfire, and at least one vehicle ended up being burned to the ground.
The incident resulted in the Los Angeles Police Department advising people to avoid downtown areas due to toxic fumes from the robotaxis’ burning lithium-ion batteries. As noted in a KRON4 report, Waymo ultimately halted service in affected areas “out of an abundance of caution.”
Robotaxi Sentiments
The cost of the attacks is notable. Each Waymo robotaxi is valued between $150,000 and $200,000, per a 2024 Wall Street Journal report. Interestingly enough, this is not the first time that Waymo’s robotaxis ended up on the receiving end of angry protesters. On February 24, a Jaguar I-PACE robotaxi was set ablaze and vandalized by a crowd in San Francisco. Videos taken at the time showed a mob of people attacking the vehicle.
Despite the recent attacks on its robotaxis, Waymo has stated it has “no reason to believe” its vehicles were specifically targeted during the protests, as per a report from The Washington Post. A company spokesperson also noted that some of the Waymo robotaxis that were defaced and destroyed during the violent demonstrations had been completing drop-offs near the protest zones.

xAI targets $5 billion debt offering to fuel company goals
Elon Musk’s xAI is targeting a $5B debt raise, led by Morgan Stanley, to scale its artificial intelligence efforts.

xAI’s $5 billion debt offering, marketed by Morgan Stanley, underscores Elon Musk’s ambitious plans to expand the artificial intelligence venture. The xAI package comprises bonds and two loans, highlighting the company’s strategic push to fuel its artificial intelligence development.
Last week, Morgan Stanley began pitching a floating-rate term loan B at 97 cents on the dollar with a variable interest rate of 700 basis points over the SOFR benchmark, one source said. A second option offers a fixed-rate loan and bonds at 12%, with terms contingent on investor appetite. This “best efforts” transaction, where the debt size hinges on demand, reflects cautious lending in an uncertain economic climate.
According to Reuters sources, Morgan Stanley will not guarantee the issue volume or commit its own capital in the xAI deal, marking a shift from past commitments. The change in approach stems from lessons learned during Musk’s 2022 X acquisition when Morgan Stanley and six other banks held $13 billion in debt for over two years.
Morgan Stanley and the six other banks backing Musk’s X acquisition could only dispose of that debt earlier this year. They capitalized on X’s improved operating performance over the previous two quarters as traffic on the platform increased engagement around the U.S. presidential elections. This time, Morgan Stanley’s prudent strategy mitigates similar risks.
Beyond debt, xAI is in talks to raise $20 billion in equity, potentially valuing the company between $120 billion and $200 billion, sources said. In April, Musk hinted at a significant valuation adjustment for xAI, stating he was looking to put a “proper value” on xAI during an investor call.
As xAI pursues this $5 billion debt offering, its financial strategy positions it to lead the AI revolution, blending innovation with market opportunity.
