Phil Energy Strengthens All-Solid-State Battery Mass Production Partnership with Visit from Factorial CEO at InterBattery

Phil Energy, a manufacturer of secondary battery equipment led by CEO Kim Kwangil, showcased its technological capabilities at InterBattery, the largest battery event in Korea. The company highlighted its next-generation battery portfolio, which is closely linked to globally trending industries such as physical AI and humanoids. Notably, Factorial, a company collaborating with Phil Energy on the development and mass production of all-solid-state batteries, visited the booth, signaling a strengthening partnership and attracting attention.

Phil Energy announced on March 16 that it participated in 'InterBattery 2026', held for three days starting March 11 at COEX in Gangnam-gu, Seoul. The company actively promoted its technical prowess by exhibiting its diversified portfolio, including its core stacking and notching equipment, as well as all-solid-state battery equipment and 46mm cylindrical battery winders.

The all-solid-state battery technology stood out among the portfolio. Phil Energy is developing equipment in partnership with key clients and has already shipped equipment, demonstrating its advancement in technology.

At this InterBattery event, the company reaffirmed expectations for collaboration with Factorial Inc., a U.S.-based all-solid-state battery firm in which it has made a strategic investment. Siyu Huang, CEO of Factorial, visited the Phil Energy booth and reviewed the showcased portfolio, assessing the technological capabilities. A representative from Phil Energy stated, "We plan to accelerate our collaboration with Factorial, a global top-tier company in the all-solid-state battery sector, and achieve visible results quickly. Through this partnership, we expect to add momentum to our strategy of diversifying both our client base and portfolio."

Phil Energy recently followed up a strategic MOU with an equity investment, a move aimed at rapidly responding to the growth of the all-solid-state battery industry. Factorial's shareholders include global automakers and materials companies, reportedly forming an extensive value chain for establishing an all-solid-state battery ecosystem.

It was also reported that Phil Energy recently secured investment from In-Q-Tel (IQT), a venture capital firm established by the U.S. Central Intelligence Agency (CIA). This investment is interpreted as an effort to foster industries such as drones, unmanned aerial vehicles, and robotics. As the first equipment manufacturer to become a shareholder in Factorial, Phil Energy is well positioned to benefit from the industry's expansion.

A representative from Phil Energy remarked, "We have been steadily increasing our overseas client base and signing more contracts to pioneer new markets. We will continue efforts to move away from a simple business structure, which has been pointed out as a weakness despite our strong technological capabilities." He added, "This year is expected to be a turning point in terms of business performance. In addition to enhancing technology, we will actively reorganize the company to improve internal operational efficiency."
