ASPILSAN Enerji Industry and Trade Inc., established in 1981 in Kayseri, Turkey, is a top-tier battery manufacturer with over four decades of expertise in energy systems and defense technology. As a subsidiary of the Turkish Armed Forces Foundation, the company holds a unique position in advancing local technological sovereignty.
Specializing in lithium-ion and other specialized batteries, ASPILSAN serves industries ranging from aerospace and defense to medical devices and renewable energy storage. Its primary facility, located in Kayseri’s Mimarsinan Industrial Zone and spanning 25,000 square meters, aims to produce 21 million batteries annually, solidifying its role in Turkey’s energy transition. By combining heritage in niche applications with cutting-edge manufacturing, the company drives innovation in areas such as solid-state batteries and fuel cells while adhering to international quality standards like EASA, ISO, and NATO certifications.
Battery Technology
ASPILSAN Enerji’s technical expertise centers on lithium-ion batteries engineered for high-stakes applications. Key offerings include the INR18650A28 cell, a 2,800mAh 18650-format battery optimized for aviation, defense, and electric vehicles, and larger 21700-cell variants for industrial use. The company’s aviation batteries power Turkey’s flagship military projects, such as the KAAN combat jet, TÜRAN trainer aircraft, and torpedo systems, leveraging both Ni-Cd and advanced lithium chemistries. To support these innovations, R&D facilities in Kayseri and Ankara focus on cell design, battery management systems, and integration into sectors like rail transport, medical equipment, and renewable energy grids.
Beyond conventional cells, ASPILSAN explores next-gen technologies like proton exchange membrane (PEM) fuel cells (50W–100kW) and batteries for space applications, emphasizing vertical integration—from electrode production to turn-key battery packs. This end-to-end approach ensures reliability and compliance with stringent safety and environmental standards, enabling partnerships with global clients in aerospace and defense.
Recent Projects
Recent milestones include a February 2025 collaboration with Turkish Aerospace Industries (TUSAŞ) to localize aviation battery cell production for fighters like the HÜRJET jet. The company’s 2024 launch of its Kayseri lithium-ion facility added 220MWh annual capacity, boosting domestic production. At the SAHA Expo 2024, it debuted its commercially viable 18650 cells and showcased a 21700 design for heavy machinery. EU Horizon Europe funding under the BASE project supported development of a digital battery passport system, enhancing recyclability.
Exports of lithium-ion cells have expanded to the Middle East and Europe, with preparations underway for certification targeting U.S. markets. Notably, ASPILSAN’s battery systems were integral to the successful maiden flight of Turkey’s KAAN jet in 2024, marking a leap in national defense autonomy.
Investors
Primarily owned by the Turkish Armed Forces Foundation (98%), ASPILSAN leverages institutional backing to prioritize state-driven technological projects. Government incentives and EU Horizon Europe grants have financed advanced initiatives like fuel cell development and digital infrastructure. Strategic alliances, including partnerships with TUSAŞ, provide further momentum for aerospace and military battery innovation.
