Two next-generation battery material and cell manufacturers are cooperating to expedite solid-state battery development. LG Chem and Factorial Energy have signed a Memorandum of Understanding, hoping to eventually lead the solid-state battery segment with a strategic partnership.

Factorial Energy is a Massachusetts-based solid-state battery developer that has been developing energy-dense solid-state technology for EV propulsion applications. This includes its flagship product, the 100 Amp-hour (Ah) Factorial Electrolyte System Technology (FEST) solid-state cell.

This proprietary battery technology is compatible with existing lithium-ion battery manufacturing equipment, enabling automakers to transition to the advanced cells more seamlessly.

Those solid-state cells have been UN-certified, and A-sample battery cells have been sent to OEM partners. All while Factorial continues cell production at a brand-new facility in its home state. Meanwhile, LG Chem has invested billions in battery material development, particularly those required in cathodes, including solid-state cells, while setting up its own US facilities following a long-term supply contract signed with General Motors.

Now, LG Chem and Factorial are combining their respective expertise in battery materials and manufacturing practices to speed up solid-state battery development and implementation.

LG Chem and Factorial to combine solid-state know-how

To accelerate the development of solid-state batteries, LG Chem and Factorial Energy say they will collaborate, pairing the former’s battery material capabilities with the latter’s next-generation battery material and process innovations. Per Factorial CEO Siyu Huang:

We are thrilled to enter into this collaboration with LG Chem, one of the pre-eminent global leaders in battery materials. The electric vehicle industry is at the cusp of a much-needed breakthrough in battery technology, and we believe that close supply chain partnerships will help accelerate this transition. Together with LG Chem, we’re advancing the development of critical solid-state battery technology that will unlock the electric vehicle future.

Following the initial solid-state development project, LG Chem and Factorial stated they would explore technology licensing and material supply as part of an expanded strategic partnership with hopes of taking the market. LG Chem CTO Jong-ku Lee also spoke to the signed MOU:

Through this collaboration, we will become technology leaders in the field of next-generation batteries. We expect to secure solid-state materials through Factorial’s accumulated experience in next-generation batteries and LG Chem’s superior material technology.

Details of the new partnership remain light at this point, but this has the makings of a lucrative partnership, as Factorial can benefit from LG Chem’s cathode and other battery material expertise. At the same time, LG Chem can successfully supply essential materials to Factorial’s FEST solid-state cells, especially as they develop toward scaled production.

Electric aircraft developer BETA Technologies has shared video footage of its ALIA eVTOL transitioning from vertical takeoff to forward propulsion in its latest test video. This is a key milestone as the company seeks certification for the aircraft ahead of several use cases.

BETA Technologies is a fully integrated electric aircraft and systems developer based in Vermont that we’ve been reporting on since 2021 with the debut of its first electric vertical takeoff and landing (eVTOL) aircraft – the ALIA-250, which has since been renamed the ALIA VTOL.

The ALIA VTOL has since been joined by an electric conventional takeoff and landing (eCTOL) plane called the ALIA CTOL, which has flown tens of thousands of test miles to date en route to evaluation flights for FAA certification and is targeting full approval for commercial operations by 2025.

US Air Force project AFWERX remains a partner and long-time collaborator with BETA Technologies, helping develop its eVTOL and eCTOL technology. Recent updates have included a lot progress with the ALIA eCTOL, including international flights to Canada and a successful testing deployment with the US Air Force.

Recently, however, BETA has been touting a key milestone in the development of its ALIA eVTOL, transitioning from vertical takeoff to forward flight while in the air.

Watch BETA’s ALIA eVTOL transition mid-flight

We recommend watching the five-minute flight video below, which gives you an idea of all the prep and testing that went into the eVTOL’s first transitional flight before BETA ever left the ground. While the transition may seem simple at first glance, it’s rather difficult to engineer an aircraft that can take off in one direction and then adjust its rotors to move on an entirely different axis… all while in the air.

BETA stressed the importance of this eVTOL flight test milestone because it validates the ALIA’s “lift and cruise” design. As a simpler solution to the challenge of runway independence, BETA believes it can certify its eVTOL aircraft more quickly.

Better yet, BETA relayed that its eVTOL design significantly reduces maintenance and cost while increasing flight reliability and safety. All without any air pollution. Per the release:

We’ve been progressing toward this technical milestone for a while. It’s a new flight regime, and we fly all our missions with a pilot in the seat, so we approached it the best way we know how: by respecting physics. Like everything we do at BETA, we took a methodical, step-by-step approach.

Transition — and all of the incremental testing leading up to it — provides us with the data we need to validate our design decisions as we continue toward certifying A250. It also brings us one step closer to getting this technology into the market and into the hands of our customers to complete meaningful missions

Looking ahead, BETA says the ALIA aircraft will be used by the military first, then cargo carriers and commercial passenger operations. The ALIA eVTOL transition test seen below was piloted by Nate Moyer, BETA test pilot, and former experimental test pilot for the US Air Force:
