Throughout 2025, ASPİLSAN Enerji made tangible contributions to Türkiye's technological independence with domestic lithium-ion cell production, R&D investments, and international collaborations, spanning a wide range from defense to energy storage.
Evaluating the year 2025, ASPİLSAN Enerji General Manager Prof. Ahmet Turan ÖZDEMİR drew attention to the strategic importance of battery technologies with the following statement: “Battery technologies are no longer solely about energy storage. Lithium-ion batteries, as the oil of today and the future, have become a factor that determines the strategic destiny of countries across many fields, from defense to transportation, from aviation to renewable energy. For this reason, the capability to develop and manufacture battery cells is not only a need of today, but a strategic necessity for future generations.”
Just as oil determined the destiny of nations in the 20th century, lithium-ion batteries and the critical minerals on which they rely are assuming this role in the 21st century. Therefore, domestic battery cell production is not merely an economic activity, but a strategic domain of sovereignty.”
Özdemir emphasized that 2025 was a year in which this strategic approach was reinforced with tangible outcomes for ASPİLSAN Enerji, and in which the domestic and national battery ecosystem was placed on stronger foundations.
Continuity and Capability in Domestic Lithium-Ion Cell Production
“Kayseri’de faaliyet gösteren lityum iyon pil hücresi üretim tesisinde, 2025 yılı boyunca seri üretim kabiliyeti, kalite standartları ve proses güvenilirliği daha da ileri taşındı.
In addition to battery solutions used in critical platforms for the defense industry, ASPİLSAN Enerji strengthened its position as a multi-domain technology manufacturer with its product portfolio for civil aviation, energy storage systems, and industrial applications.
R&D and Engineering-Driven Growth
In 2025, R&D activities focused on developing cell chemistry, battery management systems (BMS), and strengthening performance and safety testing infrastructure.
Patent applications are an important technological output, and we will be submitting even more patents next year. In this context, 4 patent applications and 1 design registration application have been filed. In addition to the numerous ongoing contract-based projects for our country’s critical platforms, 5 new project support applications have been submitted, 1 of which is international.
In 2025, ASPİLSAN Enerji also crowned its achievements with awards. In the 2025 OSB Stars Survey announced by OSBÜK, the company ranked 13th among the firms with the highest R&D expenditures, once again demonstrating that it is an R&D-driven company that designs and produces. Additionally, in the “Accelerating Exports” competition organized by the Exporters’ Association, ASPİLSAN Enerji was awarded the Bronze Award in the Sustainability and Environmental Contribution category.
The year 2025 concluded with 4 active projects, 3 of which are international, with a total budget exceeding 2 million euros. Through university-industry collaborations and participation in technical activities, knowledge generation was not limited to products alone but was also supported by human resources and engineering culture. In this context, ASPİLSAN Enerji became the defense industry company receiving the most funding in 2025.
Incentive Mechanisms, Publicly Supported Projects, and Strategic Contributions
In 2025, ASPİLSAN Enerji actively participated in offset programs, continuing its operations in an integrated manner with public supports, development agencies, and national incentive mechanisms. Numerous incentive programs were regularly monitored, and applications deemed eligible during the relevant periods were submitted systematically.
Within this scope, two significant projects were implemented under the ORAN Development Agency – Technical Support Program. Additionally, a project application was submitted to the Energy Market Regulatory Authority (EPDK) titled: “Lithium Iron Phosphate (LFP)-Based Energy Storage and Proactive Predictive Maintenance Supported Energy Management Solution for Distribution Companies for Electric Vehicle Charging Stations.
ASPİLSAN Enerji has also played an active role in TÜBİTAK projects, continuing to strengthen its technology development and domestic production capabilities.
OTAĞ Activities and Contributions to the National Technology Ecosystem
Within the scope of the Battery Technologies Focus Technology Network (OTAĞ) program, initiated under the leadership of the Presidency of Defense Industries, the aim has been to assess the current status of battery and battery sub-component technologies in our country and to develop a comprehensive roadmap for both existing and planned future focus areas.
Within this scope, ASPİLSAN Enerji participated as the leader of the Battery Management Systems (BMS), Control Technologies, Packaging, and Integration Focus Working Group (FWG); the Battery OTAĞ group was established, and activities have been initiated.
International Visibility and Strategic Partnerships
In its 44th year of establishment, ASPİLSAN Enerji significantly enhanced its international visibility.
In 2025, the company participated in numerous international fairs and industry events, including CES in the USA, LAAD in Brazil, EV Show in Germany, and Middle East Energy in Dubai.
Throughout the year, more than 300 domestic and over 60 international visits were conducted across 13 countries and 3 continents, providing a strong foundation for technology collaborations, export potential, and long-term strategic partnerships. Türkiye’s position as one of the few countries capable of producing domestic battery cells has significantly increased international interest in our country during these engagements.
Within this scope, ASPİLSAN Enerji achieved a 25% increase in revenue in Turkish Lira terms. In addition, by participating in the Global Supply Chain Finance process, its international commercial capabilities were strengthened.
A New Generation Brand: TETRONE BATTERIES is Born
In 2025, we decided to leverage the high-tech and engineering expertise we have gained in the defense industry and present it in the civilian sector through our TETRONE BATTERIES brand, aiming to enhance the perception of quality.
We aimed to integrate our knowledge and experience in energy storage systems into consumer electronics and mobile systems, creating value in everyday life. TETRONE BATTERIES is not just a battery brand; it has established itself as a next-generation energy platform, centered on energy efficiency, sustainability, and customer satisfaction.
Including sales through our TETRONE brand, we reached a total of 490 new customers.
Sustainability and Corporate Responsibility
Energy efficiency, environmentally friendly production processes, and a sustainable industrial approach remained an integral part of all activities in 2025. Social responsibility projects and education-focused initiatives further demonstrated that ASPİLSAN Enerji is not only a manufacturing company but also an organization that prioritizes societal benefit.
A Strong Vision for the Future
At ASPİLSAN Enerji, we understand that having a leading role in battery technologies is not only an economic gain but also a matter of national security and technological independence. Every step taken in 2025 is regarded as a building block contributing to Türkiye’s long-term energy and defense strategies.
In 2026, we will continue forward with stronger goals, bolder steps, and a greater vision. With a strong team mindset that embraces change, drives development, and believes in achieving together, ASPİLSAN Enerji will steadfastly continue to add value to our country.
