Philenergy (est. 2020) is a South Korean manufacturer of automated equipment for battery production — precision laser notching, continuous winders (46-phi), stacking, and electrode systems — serving EV makers and grid-scale storage producers with production-grade automation and inspection.
Philenergy Co., Ltd., founded in 2020 and headquartered in Osan, Gyeonggi-do, South Korea, develops automated equipment for secondary battery assembly and related processes. Led by CEO Kim Kwang-il, the company supplies laser notching, winding, stacking, and electrode production machinery for electric vehicle and energy storage manufacturers. Philenergy operates internationally with offices in Hungary and the United States and is part of the Philoptics Group. Its stated mission is to enable high-volume, high-precision battery manufacturing through equipment that increases throughput, improves quality control, and supports next-generation chemistries such as solid-state cells. The company emphasizes process standardization, automated inspection, and real-time control to reduce scrap rates and accelerate factory ramps for EV and grid-scale battery producers.
Philenergy’s core technology centers on automated, high-throughput production equipment for secondary batteries. Offerings include ultra-high-precision laser notching for electrode trimming, continuous (non-stop) winding systems for cylindrical cells, and stacking modules for prismatic formats. Supporting capabilities comprise roll-to-roll material handling, real-time tension control, and automated visual inspection with algorithmic defect detection. Machines are configured for solid-state processing and conventional lithium-ion chemistries, enabling improved safety and reduced material waste through tighter tolerances and fewer process interruptions. The company emphasizes modular, standardized modules for line scalability and process repeatability, which help manufacturers achieve higher yield, faster ramp-up, and consistent cell quality across large production volumes.
Philenergy supplies laser notching systems, continuous winders for 46-phi and other cylindrical formats, stacking equipment for prismatic cells, electrode production tools, and automated assembly lines for ESS modules. Products focus on throughput, precision, and inline inspection to reduce defects and support high-volume EV and stationary energy storage manufacturing. Industries served include automotive OEMs, battery manufacturers, and grid-scale storage system integrators.
In 2024–2025 Philenergy secured orders for 46-phi cylindrical winders from battery manufacturers aiming to scale EV cell output and exhibited solid-state and mass-production equipment at InterBattery 2025. The company also presented winding and stacking systems at Battery Show Europe 2024. These activities generated commercial orders and expanded engagement with OEM and battery supplier clients; specific capacity figures were not disclosed in the provided materials.
Major shareholders include Philoptics Co., Ltd. (42.33%) and Samsung SDI Co., Ltd. (14.09%). Samsung SDI invested 5 billion won and holds a non-executive board seat. Philenergy completed an initial public offering in July 2023, raising about 95.6 billion won from institutional investors. Other disclosed individual shareholders include CEO Kwang-il Kim. No additional venture capital rounds or undisclosed investors were cited in the source material.
