Enovix Launches AI-1™: A Revolutionary Silicon-Anode Smartphone Battery Platform
FREMONT, Calif., July 07, 2025 (GLOBE NEWSWIRE) -- Enovix Corporation (Nasdaq: ENVX) ('Enovix'), a leader in advanced silicon battery technology, today announced the launch of the AI-1TM platform, its Artificial Intelligence ClassTM batteries for the next generation of mobile smartphones that require significantly higher total energy storage and power to perform AI functions locally. This revolutionary silicon-anode smartphone battery platform is protected by 190 Enovix architecture-specific patents that enable the use of 100% active silicon anodes. Last week, the company sampled its first 7,350 milliampere-hour (mAh) AI-1 batteries to a leading smartphone OEM for qualification in the first ever 100% silicon-anode battery smartphone launch.
With energy density exceeding 900 watt-hours per liter (Wh/L) and advanced capabilities for high discharge rate and long cycle life, Enovix believes AI-1 is the highest energy density battery commercially available in the market today. The company's patented battery architecture overcomes the notorious silicon anode swelling problems, enabling exceptional performance without compromising safety or longevity. The higher energy density provided by the AI-1 enables smartphone manufacturers to take full advantage of AI-enabled applications without requiring frequent charging cycles.
AI-1 Performance Highlights*:
>900 Wh/L energy density – highest commercially available
Fast charging at 3C rates – 20% charged in 5 minutes, 50% charged in 15 minutes
900+ cycles in standard smartphone usage based on initial unit testing
High discharge capability across wide temperature ranges – ideal for AI applications
Passed Enovix Safety Test Suite (ESTS): drop, tumble, thermal abuse, and external short circuit test
* Based on internal testing
'Enovix invented technology that led the industry in energy density for wearables in 2023 thanks to our unique architecture and the use of 100% silicon-anode technology,' said Dr. Raj Talluri, CEO of Enovix. 'However, when I joined as CEO, I recognized that the portion of the wearables market immediately available to us would not be enough to support our full revenue plan, so I decided to take the opportunity to introduce our breakthrough battery to the much bigger smartphone market and the Enovix story to the smartphone accounts that I knew well from running Micron's $6 billion mobile memory division. With the launch of AI Class technology, we are now sampling production AI-1 batteries to those customers who demand not only industry-leading energy density, but have other stringent requirements for cycle life, fast charging, and safety. Enovix is now positioned to support the next generation of smartphones in a 1.2-billion unit market.'
T.J. Rodgers, Enovix Chairman, said, 'The AI Class technology is a breakthrough in utilizing the significant but difficult-to-realize benefits of silicon anodes to win in the AI Class smartphone market. The approximate 80,000 wearable batteries produced in our Fremont fab – and even the fab itself – all had to be re-engineered to meet the challenges of the first AI-1 battery. To move from small wearable batteries – with low power consumption and 500-cycle life – to the big, high-power, AI Class batteries, we had to change the anode (five times), the cathode (three times), the electrolyte (ten-plus times), and even the stainless-steel constraint and separator. Each experimental set took months to create and evaluate, and that effort was only possible because of the scale of our 50-engineer R&D group which touts 30 PhDs. Making these major changes was the primary cause of the delay between my January 3, 2023 presentation to shareholders and the sampling of the AI-1. That two-year delay was frustrating, but we are now on the other side of the problem with 100 R&D man-years of distance added between us and our competitors. We have also discovered that our AI Class process, which produces 900 smartphone Wh/L of energy density, will produce wearable batteries meeting 2023 smartwatch requirements with over 1,000 Wh/L of energy density due to the added capabilities of the AI Class process.
Rodgers continued, 'An AI-1 battery, built in our Malaysian production facility, is shown in Figure 1. While it is only 1.79 cubic inches in volume, it holds 7.35 amp-hours of charge and 26.3 watt-hours of energy. Humans cannot comprehend the high rate of energy use in the AI world because it is dissipated invisibly by charging and discharging the 100 billion transistors on a modern AI chip. In the Figure, we also show the same 26.3 Whrs of energy applied to a human-scale problem, lifting a 4,948-pound truck to a working height of 4.7 feet on a commercially available hydraulic lift – three times on one battery charge.
Rodgers concluded, 'We have over $200 million in the bank and thank our shareholders for supporting us on every step of our journey. I started at Enovix in 2012 and have learned that making a new state-of-the-art battery is a decade-long marathon, a lot more difficult than a one-generation change in semiconductors under Moore's Law. It all started that way for the Sony corporation, which took 10 years to bring the first lithium-ion battery to market in 1991. Fortunately, we expect future generations of the AI Class technology to reuse this foundation, allowing us to raise the bar on energy density progressively as we transfer each new AI process modification to our Malaysian factory.'
AI-1 is currently available to select smartphone OEMs. Broader availability is expected later in 2025.
Figure 1. The first AI-1 cell is just 1.79 cu. in. in volume, yet it contains 26.3 watt-hours of electrical energy, enough to power a typical car lift to raise and lower a 4,948-pound truck to a working height of 4.7 ft – three times per charge.

This Fast-Casual Chinese Chain Is Beating Local Spots At Their Own Game
Let's face it: America's very fond of chain dining. Whether it's one of the best regional fast food chains or one of the ubiquitous giants, corporate eating covers every context. And both the cuisine and locations of such operations are rapidly evolving: It's not just about burgers or fried chicken anymore. And now, Pei Wei is once again changing the game. Since starting some 25 years ago in Arizona, the chain operates over a hundred locations all across the country. During their first decade of preparation, several factors set them apart. They were among the earliest corporate adopters of gluten-free and allergy sensitive dining. And the interior is sleek, but still casual, with a convenient counter service model that saves costs. Last -- but certainly not least -- for easy-going Pan-Asian fare, the eclectic menu hits the spot: Think classics like orange chicken, Mongolian beef, as well Poke bowls, Thai-influenced curries, and more. Throw in affordable pricing, and such a combination of factors cemented their enduring growth -- a valued evidenced by their (and P.F. Chang's) acquisition for over a billion dollars in 2012. Such a scale cements Pei Wei as the second biggest player in Asian food. The more fast-food like Panda Express menu is the only company that more commercially successful. However, for many Americans, Pei Wei even beats out local, hole-in-wall options. Read more: Chain Restaurants That Serve The Highest And Lowest Quality Steak Pei Wei may have introduced you to classics like orange chicken, but the chain didn't invent Chinese-American cuisine. Instead, many items off their menu are adapted versions of fare that traces roots to 19th century California. It's here that Cantonese-run eateries -- especially densely cluttered in the Bay Area -- first created tasty and affordable dishes like chop suey. And the creation of orange chicken is accredited to Panda Express in 1987. So while Pei Wei does offer a few signature dishes like their protein bowls and salads, they mainly stick to tried and true Asian-American classics. Pei Wei broke into such a formula by way of P.F. Chang's, their more upscale counterpart chain which opened in 1993 (and now boasts a great happy hour). An innovator in specifically wok-driven dishes sold to American audiences, P.F. Chang's has enjoyed popularity since the 1990s, with their snazzy surroundings yet comforting fare. The parent company launched Pei Wei in 2000 to deliver simpler Asian-American classics in a more casual environment, with less overhead. The move proved hugely commercially successful, leading to the chain that still thrives today. Read the original article on Chowhound.

Microsoft Offers Free Windows 10 Extended Security Updates: Here's How to Get Them
Microsoft is closing the door on Windows 10 in October 2025, and will be ceasing security support for that operating system unless users pay $30 for a one-year extended security update. Now, Microsoft has added a free option. Users need to turn on cloud backup and connect it to their OneDrive account. The ability to get free updates on Windows 10 is a pretty big deal because it is still the most widely used Windows OS, accounting for just over 53% of installs as of May 2025. That leaves millions of people without security support in just a few months unless they upgrade. So the cloud backup option gives users a way out without costing them any money. The only potential issue is OneDrive. Anyone with a Microsoft account gets up to 5GB of storage for free. However, as The Verge points out, some backups may exceed this limitation, requiring users to purchase a monthly or yearly plan. At $1.99 per month for 100GB of cloud storage, a year of OneDrive still costs less than the $30 for a year of additional security updates, but it still may cause frustration among some users. Windows 10 was released in July 2015, more than a decade ago. Microsoft will be rolling out the ESU wizard in July 2025. Microsoft How to get Windows 10 security updates for free Per Microsoft's blog post, there are now three options for people who want to stay on Windows 10 and still receive security updates. Use Windows Backup to sync settings to the cloud via OneDrive. Redeem 1,000 Microsoft Rewards points. Redeeming those points can buy you one year of security updates. Pay $30 for the extended security updates program. Users will be presented with these options starting in July, which is when Microsoft plans to roll out the sign-up wizard for the Extended Security Updates program. Signing up for this option will guarantee updates until Oct. 13, 2026, although businesses will have the option to purchase up to three years of additional updates. So, this isn't a long-term solution, but rather gives consumers more time to upgrade to Windows 11. It's been an uphill battle for Microsoft as people have been resilient in upgrading their existing hardware. There are myriad differences between the two operating systems, but Microsoft's string of unpopular decisions along with Windows 11 compatibility issues have kept the prior generation OS around a lot longer than it normally would be.
