What Aspilsan Enerji does

Aspilsan Enerji Sanayi ve Ticaret A.Ş. is a privately-held Turkish battery manufacturer and 98.52%-owned subsidiary of the TSKGV (Turkish Armed Forces Foundation), headquartered at Kayseri Mimarsinan Organized Industrial Zone. Founded on April 2, 1981, the company operates across defense, aviation, telecommunications, rail, marine, medical, robotics, e-mobility, energy storage, and consumer electronics sectors, producing both lithium-ion cylindrical cells (18650 and 21700 formats across NMC, NCA, LFP, LCO, LMO, and LTO chemistries) and complete battery systems, including Turkey's only Ni-Cd aviation/helicopter battery systems. The company became Europe's first serial producer of 18650 lithium-ion cells in June 2022 and executed Turkey's first battery export.

The core technology stack spans 100% domestically owned intellectual and industrial property rights on the INR18650A28 cell (NMC, 2800 mAh, 3.65V nominal) and the new A35 cell (3500 mAh, silicon/graphite composite anode), produced at a 25,000 m² facility in Kayseri with a 60ppm serial production line capable of 220 MWh/year and 21 million cells per year. Three Ministry-recognized Ar-Ge merkezi (R&D centers) — Battery Systems in Kayseri, Electronics and Cell Design and Development in Ankara, and Hydrogen Technologies in Istanbul — support end-to-end capabilities including electrode manufacturing, PCB/electronic card design and production, BMS algorithm design, thermal and structural analysis, plus chemical, environmental, electrical, and EMI/EMC testing services per MIL-STD-461 and DO-160.

The business model is B2B hardware sales with quote-based pricing across multiple verticals, supplemented by contract manufacturing services (electrode and 18650 cell production, electronic card manufacturing) and third-party testing services. Distribution combines direct enterprise sales (defense, aviation, telecom, industrial accounts) with three authorized Turkish distributors (TETRONE, Birikim Pilleri, PİLSAN). Customers include the Turkish Armed Forces, ASELSAN, ROKETSAN, TUSAŞ, HAVELSAN, Turkcell, Türk Telekom, lifecell, and ULAK, with formal manufacturing approvals from Panasonic and LG Energy Solutions. Quality certifications include AQAP 2110 (NATO), AS9100 (aerospace), ISO 9001/14001/45001/50001, ISO/TS 22163 (IRIS rail), UN38.3, IEC 62133-2/61960-3/62619, and UL 1642.
