2. History and Workforce
PHILOPTICS was founded in 2008 and grew into a laser optics equipment specialist in the semiconductor and display fields, listing on KOSDAQ in 2017. It established Phil Energy via a spin-off to enter the secondary battery equipment business, and Phil Energy is developing next-generation battery equipment in parallel, based on its core stacking and notching equipment.
Together with its subsidiary Phil Energy (secondary batteries), PHILOPTICS has also recently been expanding into the glass substrate process equipment business for semiconductors (TGV, singulation). Detailed workforce composition is (undisclosed).
3. Core Technology and Key Equipment
The company states it has developed picosecond (one-trillionth-of-a-second)-class laser notching equipment that cuts electrode material with a laser, achieving more precise cutting, higher speed, and less heat loss compared to existing press-die notching.
- Picosecond laser notching equipment — precise cutting and low heat loss versus press method
- Stacking equipment — flagship product
- Winder for 4680 cylindrical batteries — recent order win
- UHP (Uniform & High Pressure) stacking equipment for solid-state batteries (commercialization under review)
- Lithium-metal anode post-processing equipment (lineup expansion in progress)
4. Production Infrastructure and Quality Assurance
The company is based near the Osan materials/parts/equipment cluster together with parent company PHILOPTICS. Detailed plant area and capacity figures are (undisclosed).
5. Delivery Track Record and Partnerships
The Electronic Times has reported that Korea’s 3 major battery makers — LG Energy Solution, Samsung SDI, and SK On — are actively adopting laser notching equipment. Individual contract details are (undisclosed).
