Solid-state battery developer Factorial Energy has announced a major milestone in bringing its energy-dense cells to EVs one day. A-Samples of its 100+ Ah Factorial Electrolyte System Technology (FEST) solid-state battery cells are making their way to the company’s automotive partners around the globe – who those specific OEMs are though is up for dispute.
Factorial Energy is a Massachusetts-based solid-state battery developer that has been working for an entire decade to develop and eventually manufacture energy storage technology to support zero-emission propulsion applications.
The company hit a major milestone this past January at CES, when it debuted a 100 Amp-hour (Ah) prototype of flagship product – the Factorial Electrolyte System Technology (FEST) solid-state cell. This proprietary battery technology offers compatibility with existing lithium-ion battery manufacturing equipment that can enable automakers to transition to the advanced cells more seamlessly.
By May, Factorial shared that those solid-state cells had been UN certified to begin shipping to automakers to test for themselves before being integrated into new EV models. The battery developer currently participates in multiple joint ventures with some noteworthy names in automotive, including Mercedes-Benz, Hyundai Motor Group, and Stellantis.
Today, Factorial announced it has officially begun delivering to OEMs alongside news of a new R&D facility near Boston. Here’s the latest.

Automakers begin testing Factorial’s solid-state cells
According to Factorial Energy, its commencement of deliveries to OEMs marks the first-ever global shipment of 100+ Ah lithium-metal cells to pass UN 38.3 safety tests.
The battery developer is remaining mum on which global OEMs have received the A-sample cells, but a glance back to the paragraph above should give a hint. That said, nothing has been confirmed by Factorial. Company CEO Siyu Huang spoke to today’s latest news as another key milestone achieved this year alone:
After our CES announcement of the 100+ Ah cell, and the UN 38.3 test success, this marks another major milestone and demonstrates our progress towards commercialization. Factorial is committed to meeting automotive timelines and producing solid-state batteries that meet the industry’s highest standards. We continue to be at the forefront of building a disruptive product and are excited for our solid-state battery technology to enable automakers to offer higher-performing and safer electric vehicles to customers.
In addition to the news of A-sample solid-state cells shipping out to OEMs, Factorial announced the opening of a new 50,000-plus-square-foot facility in the Greater Boston area dedicated to the production of said cells for its automotive partners.
Complete with a dry room and wet lab, the company says its new state-of-the-art facility will “expand the development with Factorial’s automotive partners across next-generation battery technology platforms and manufacturing engineering competency.”
As we reported back in June, Factorial already has South Korean metal refining company Young Poong lined up to research and implement lithium-metal recycling into its production practices as it tries to scale its FEST cells into full commercialization and, hopefully, future EVs.

Zhengzhou Nissan has launched a new, plug-in pickup in the Chinese market called the Z9. It’s the same size as the Nissan Frontier Pro, offers over 35 miles of all-electric range, and pricing starts at just $16,600.
UPDATE 04NOV2025: more details and more markets for 2026.
The rebuilding of Nissan started to pick up earlier this year with the launch of the brand’s first plug-in pickup truck in China this past summer. The plug-in hybrid (PHEV) model offers 410 hp and an 84 mile electric-only range – more than enough for it to meet the everyday needs of most drivers with easy access to liquid fuel when needed.
It seems like a neat truck, but since it was designed and developed specifically for the Chinese market, its great specs and nearly impossible $24,800 starting price (on the entry-level Frontier Pro model) meant it would have limited impact – and limited interest – in other markets.
You can read the original post, first published back in June, below, then let us know what you think of Nissan’s plans to export its plug-in pickup to other markets in the comments.
What’s more, if you feel like spending a bit more, you can get a Zhengzhou Nissan Z9 equipped with a 32.85 kWh battery that’s good for almost 85 miles (135 km) of all-electric range. And even that extended-range model, at ¥168,900 (about $23,400) is still price-competitive with the Jeff Bezos-backed Slate EV.
In short, it’s bound to be a winner.
It’ll sell, but it won’t sell here
US-market Nissan Frontier.
With excitement surrounding the Kia Tasman, Slate, and other, similarly affordable light-duty pickups building on the success of the Ford Maverick hybrid, it should come as no surprise that Nissan has international ambitions for its newest electrified pickup.
“In alignment with our ‘In China, For China, Toward the World’ strategy for electrification and smart transformation, Nissan will fully support ZNA’s ‘off-road strategy,’” explained Stephen Ma, Chairman of Nissan (China) Management Committee and President of Dongfeng Motor Co., Ltd. “We are working to strengthen our research and manufacturing capabilities, further advancing our presence in the core markets of pickups and off-road vehicles, with the ultimate goal of achieving global expansion.”
It’s exciting stuff, but with all the recent troubles it’s been experiencing, it’s doubtful that Nissan will bring either of its new, Chinese-built mid-size pickups to the US (electrified or otherwise).
“The mission of the new generation of Chinese automotive professionals is clear – to ensure that made-in-China cars are driven across the world. ZNA will utilize its dual-brand and dual-channel advantages to expand its global footprint,” Mr. Mao Limin, Executive Vice President of ZNA, at the Z9’s launch. “We aim to be one of the top exporters of pickups within three years and to reach a sales milestone of 100,000 units.”
I’ve already written out my own comeback plans for Nissan, and this new Chinese-market pickup truck doesn’t really fit into them. Like many of you, I’m of the belief that a PHEV isn’t an EV – but I do see their value as “lilypad” cars, and the two Lightning owners I know? Their previous Ford F-150s were hybrids.

Finnish energy giant Wärtsilä has announced the latest addition to its massive network utility-scale battery energy storage system (BESS) projects in Australia: a record-breaking 1.5 GWh deployment that brings the company’s total energy storage capacity in the nation to 5.5 GWh.
The future of large-scale energy projects in Australia is looking increasingly DC-coupled thanks to Wärtsilä, which just announced plans to build the largest BESS of its kind in the National Electricity Market (NEM). The massive hybrid battery project that marks the company’s ninth site down under, and pushes its total capacity to a formidable 5.5 GWh.
The company says its latest, “record-breaking” energy storage plant is a blueprint for how to efficiently combine solar generation and storage to create a more resilient and decarbonized grid.
“This project is significantly larger than our earlier DC-coupled project, underscoring the need for this type of technology in expanding at scale,” said David Hebert, vice president of Global Sales Management at Wärtsilä. Hebert called the DC-coupled technology, “a breakthrough for hybrid renewable plants and a critical step towards establishing a financially viable renewable energy future.”

Hebert believes projects like this one play a hugely important role in stabilizing Australia’s grid while, at the same time, advancing the country’s ambitious net-zero emissions targets from the energy sector by 2045.
With a 20-year service agreement already in place and the order set to be booked this quarter, this project is a working prototype for the next generation of global renewable assets. As nations worldwide grapple with the challenge of moving beyond fossil fuels, the success of this massive DC-coupled system will provide a real-world model for how to build a grid that is cleaner, smarter, and more resilient than ever before.
Electrek’s Take Explainer
If you’re not familiar with DC-coupling, it’s an efficiency game-changer. Unlike traditional AC-coupled electrical systems that require converting solar-generated direct current (DC) to alternating current (AC) for use by the grid, and then back to DC to use in a battery, a DC-coupled system connects the solar array and battery directly. This architecture cuts energy losses that occur during conversion, capturing more solar power and significantly improving project economics and overall system efficiency.
In other words: it saves money, and shores up the grid. Wins all ’round!
