Mercedes-Benz eCampus, comprising an investment of 14 billion euros ($15.1 billion) in research, development, and manufacturing for 2024, seeks to revolutionize battery cell production and drive down costs.

Ola Källenius, Chairman of the Board of Management of Mercedes-Benz Group AG, expressed the importance of this initiative stating, “The eCampus brings us closer to our goal of playing a leading technological role in electric mobility. We aim to reduce battery costs by more than 30 percent in the coming years.”

At the heart of the eCampus is the “Industrial Cell Lab,” a 10,000-square-meter plant capable of producing tens of thousands of battery cells annually according to Mercedes-Benz. In detail, this lab covers the entire product and process chain for cell development and production, allowing the company to experiment with various cell chemistries including advanced lithium-ion cells and solid-state battery technology.

Moreover, the company is pushing the boundaries of energy density with goals to reach up to 900 Wh/l through innovations including high-silicon anodes and solid electrolytes. These advancements are projected to strongly enhance charging capabilities and overall EV performance.

Furthermore, the eCampus will operate in two stages. The first is already operational and the second, including a battery ramp-up plant, is set to be completed by the end of 2024. This two-phase approach provides a comprehensive development cycle from initial cell chemistry research to industrial-scale production and testing.

Interestingly, the eCampus features recycled concrete foundations, green roofs, and photovoltaic systems, aligning with Mercedes-Benz’s broader sustainability goals. Also, the company aspires to cover over 70% of its production energy requirements with renewable sources by 2030 and achieve 100% renewable energy usage across all production plants by 2039.

Notably, the eCampus is not just about technological advancement; it is a cornerstone of Mercedes-Benz’s circular economy strategy. The company is focusing on circular design, value retention, and closing the loop in battery technology, with plans to achieve a net carbon-neutral fleet by 2039.

Robert Habeck, German Federal Minister for Economic Affairs and Climate Action, expressed the strategic importance of the eCampus stating, “The demand for innovative and sustainable batteries will continue to rise sharply in Europe in the coming years. This facility strengthens Germany’s industrial capabilities and creates modern, future-proof jobs.”

As the automotive landscape undergoes a shift towards electrification, the Mercedes-Benz eCampus stands to contribute to that shift. By mastering both the chemical composition and industrial manufacturing processes of battery cells, Mercedes-Benz is making efforts in the field of electric mobility.
