Battery technology engineers design and refine energy storage systems for residential, commercial, and e-mobility applications, oversee and optimize manufacturing processes, and advise companies and public authorities.
Battery technology engineers contribute to the development, production, deployment, and operation of efficient, sustainable battery solutions for diverse applications—from consumer devices such as smartphones, tablets, and laptops to traction batteries for e-mobility and large-scale storage for renewable energy. They design and test prototypes, refine manufacturing methods and technologies, oversee production processes, and plan and implement energy storage systems. Their work also covers material selection with an eye to battery longevity and recyclability. In addition, they may deliver professional training within battery manufacturing companies or advise public authorities and businesses in the renewables sector on suitable storage options for generated energy.

Battery engineers design and enhance energy storage systems for residential, commercial, and e-mobility uses, shape and control manufacturing processes, and advise companies and public authorities.
As climate change accelerates the shift from fossil fuels to sustainable, climate-friendly energy, the demand for storage solutions grows. E-mobility further boosts the need for batteries, alongside countless end devices — from hearing aids, smartphones, and cordless tools to robotics and large stationary storage. Each use case imposes specific requirements on materials, performance, size, and weight. Batteries should also be durable, produced with minimal resource and climate impact, and be recyclable.
With expertise in electrical engineering, chemistry, physics, materials science, and metal/manufacturing engineering, they collaborate across disciplines. In battery manufacturing companies, they contribute along the entire value chain: from development and production to customer support, commissioning, and recycling. Tasks include prototyping, testing new production methods, designing resource- and climate-friendly processes, performing measurements and safety tests, and planning large storage systems through to commissioning.
In R&D they work on smart batteries that monitor their own state and communicate with higher-level electrical systems. They evaluate materials for charge transport, pursue performance gains, or develop printable pastes based on cobalt-free, water-soluble compounds. They also examine and optimize the role of hydrogen in battery technology.
E-mobility is a key domain: goals include increasing resilience and performance under temperature swings, humidity, salt, and vibration while reducing, for example, charging time and weight.
In product and innovation management, battery engineers act as a bridge between customers and development/production, channel user feedback, support optimization efforts, and conduct market and audience research.
Given scarce raw materials, recycling is increasingly crucial. They design processes to separate materials in environmentally friendly ways, recover and reintegrate valuables into production, and dispose of non-recyclables properly.
They also consult for authorities and private or corporate clients — e.g., on storage options for renewable energy systems — and deliver trainings and upskilling programs.
