Ex-GM exec main EV battery startup’s pivot to protection trade

An Arizona-based battery startup led by a former Common Motors government is transferring from making merchandise for all-electric autos to creating merchandise for the aerospace and protection industries amid the battle in Iran and rising demand for U.S. drones by the Trump administration.

Sion Energy expects to commercialize high-energy lithium-metal battery cells for drones and different defense-related merchandise later this 12 months after specializing in the event of all-electric autos for a lot of the previous decade, in keeping with CEO Pamela Fletcher.

“We’re focusing on to commercialize this know-how,” Fletcher informed CNBC solely. “We had hoped, and thought, that might be in automotive, and I believe that chance nonetheless exists, however the quicker path, and albeit, an enormous want, is on the market on this protection house.”

The choice is a novel instance of how corporations that guess on the unrealized adoption of all-electric autos are pivoting to completely different segments. Different corporations have moved to the stationary storage and aerospace sectors to make the most of unused battery manufacturing capability for EVs.

Automakers within the U.S. have considerably pulled again from pure EVs and brought billions of {dollars} in write-downs following slower-than-expected adoption of the autos and modifications by the Trump administration to incentives that supported them.

Sion Energy’s deliberate “Licerion HE” lithium-metal battery cells will help each major, or single-discharge, and secondary, or rechargeable, battery functions, in keeping with the corporate.

The battery cells are designed for next-generation drones, autonomous methods and different mission-critical platforms that require most power within the smallest, lightest attainable footprint, in keeping with Fletcher.

“Lithium-metal know-how, which is what we developed, has excessive gravimetric power, which implies it is lots of power in a light-weight pack,” stated Fletcher, who started main the corporate in 2024. “It really works rather well for issues that fly.”

Fletcher stated Sion Energy’s lithium-metal cells are engineered to ship power densities exceeding 500 watt-hour per kilogram, in contrast with roughly 300-350 Wh/kg for at this time’s most superior lithium-ion know-how.

Such batteries can energy drones or missiles in addition to their on-board methods akin to cameras, sensors and processors for fight, surveillance and different wants.  

Sion Energy has a 110,000-square-foot facility in Tucson, Arizona, with pilot manufacturing capabilities. Fletcher stated it is at present producing Licerion HE cells for protection functions and changing its manufacturing cell line from automotive battery cells to protection merchandise, that are smaller.

The corporate will proceed to develop cells for different segments, akin to EVs, however its most important focus and progress proper now could be protection, which the corporate had been engaged on previous to specializing in EVs, Fletcher stated.

Fletcher, a former EV and progress enterprise government who left GM in 2022, stated the chance in protection is corresponding to the continued surge in demand for power storage from information facilities throughout the U.S.

The privately held firm doesn’t plan to be a direct provider to the U.S. authorities, but it surely hopes to promote its merchandise to different licensed contractors, Fletcher stated. The transfer comes because the Trump administration’s Division of Protection is exploring growing manufacturing of U.S.-sourced Low‑Value Uncrewed Fight Aerial System, or LUCAS, drones.

Such drones have been an integral a part of the battle between Russia and Ukraine in addition to the Iran battle.

“It is developed fairly quickly within the final three or 4 years, and now, even with the Iran battle, issues are altering even additional,” Sion Energy Chief Industrial Officer Mitch Hourtienne informed CNBC. “There’s lots of rising functions popping out of, sadly, the Ukraine battle, now the Iran battle.”

A number of corporations aside from Sion Energy, akin to Quantumscape, have spent years researching and growing lithium-metal batteries for autos, however to date there hasn’t been mass commercialization for utilizing that know-how within the automotive sector.

Lithium-metal battery cells operate equally to at present used lithium-ion cells, however have better power density, doubtlessly at a decrease price. However they are often extra unstable and are seen as farther out than rising solid-state batteries for automobiles, in keeping with consultants.

Sam Abuelsamid, vp of market analysis at communications and consulting agency Telemetry, stated lithium-metal cells may very well be used for various industries and use circumstances.

“It is higher for power density. It additionally ought to scale back price,” stated Abuelsamid, an engineer and battery skilled. “There is no purpose why they would not be simply as efficient in smaller objects, particularly one thing that flies, like a drone.”

The largest distinction between protection and automotive is shelf life versus cycle life. Auto batteries sometimes require a whole lot of cost life cycles, whereas protection makes use of require just one to twenty cycles and may demand three to eight years of shelf life. 

Sion Energy has raised greater than $200 million for improvement of lithium-metal cells. Buyers have included South Korean battery producer LG Vitality Answer, former Google CEO Eric Schmidt’s household workplace, Hillspire, and unnamed world automakers, in keeping with the corporate.

The corporate, established in 1989 as a spin-off from Brookhaven Nationwide Laboratory, stated it plans to hunt additional capital as its merchandise are anticipated to launch and ramp up throughout the second half of 2026 and into 2027.
