Research & Development
Our reputation is built on our people, technology, two R&D labs and 100 years of experience. We find inspiration everywhere, we don't look to the battery industry for new ideas; it looks to us. Where we innovate others follow.
An international R&D network pushing the boundaries of knowledge
Saft relies on 200 employees dedicated to research and development, spread across its three main R&D centers: Bordeaux in France, Cockeysville in Maryland (United States), and Bangalore in India. Together, they work to imagine, design, and enhance the battery technologies of tomorrow.
At the Bordeaux site, 35 experts work specifically within Saft’s incubator, a space devoted to exploring advanced technological concepts and developing innovative solutions. Their mission: push the boundaries of knowledge, develop new processes, and bring differentiating technologies to life.
Our approach is based on close collaboration between chemists, materials specialists, mechanical engineers, electronics engineers, and software experts. This diversity of expertise enables us to innovate, improve industrial processes, design lighter and more efficient formats, and identify the most suitable solution for every battery application.
R&D at Saft: 9 steps from idea to production
All our technology is rated according to its TRL (technology readiness level). TRL 1 is an idea; TRL 9 is ready for production.
TRL 1-3 are all handled by Corporate Research. That’s when we plunder the minds of our PhD scientists. During TRL 4, 5 and 6, the technology is further developed and evaluated in one of our two incubators. TRL 7-9 sit in the hands of engineers at our manufacturing plants. This is when we test the prototypes to their limits to achieve the finished product, refining and honing what has already been proven to work.
But our R&D doesn't just focus on the end product; we also design and build our own tools, plant and machinery. This might involve establishing new processes, models and procedures, and even writing the algorithms that support development and optimize battery use.
Customized electrochemistry for any application
Our primary lithium batteries last longer (at least 20 years) than batteries from any other manufacturer. This makes them ideal for use in long-lasting applications where replacement is difficult and expensive. For example, primary lithium is the battery of choice for gas, water and electric meter companies worldwide.
Our nickel cadmium batteries work in extreme temperatures and last longer than those of our competitors, which makes our batteries the go-to choice for the aviation industry. Some 80 percent of all large commercial aircraft use our Ni-Cd batteries.
The most powerful lithium-ion batteries are made by us. They can discharge in less than 10 minutes and are capable of providing emergency power for the Joint Strike Fighter Aircraft F-35, for example, at -40°C , when most batteries would be frozen. They can also function at extremely high temperatures in Formula One cars.
Innovative battery systems development
Saft R&D also provides valuable electrochemical models for all our battery technologies. These models are useful for predicting battery behavior, aging and safety. In the case of Li-ion batteries, our scientists and engineers also develop advanced algorithms for system management. These algorithms are embedded by our electronics and software engineers in the system management of any complex Li-ion battery.
Our creative technical people are our most important asset. They forge our reputation. Their hard work is the foundation of our future.
Pioneering the next generation of battery technologies
Saft is deeply committed to advancing breakthrough energy‑storage solutions through its active involvement in major European research programs. These initiatives strengthen our leadership in emerging battery chemistries and accelerate the transition toward more sustainable, high‑performance technologies.
Our key contributions include:
- ATENA+ – Sodium‑ion Innovation: Through the ATENA+ project, Saft is driving the development of next‑generation sodium‑ion batteries, an accessible and resource‑efficient alternative that supports Europe’s strategic autonomy in critical materials.
- TALISSMAN – Lithium‑Sulfur Breakthroughs: As part of the TALISSMAN project, Saft leverages its century‑long expertise to integrate new materials, optimize manufacturing processes, and support the industrialization of lithium–sulfur technology. This lighter chemistry, with the potential to reach very high energy densities, relies on abundant materials such as sulfur, helping to reduce costs and dependence on critical raw materials.
Together, these projects showcase Saft’s long‑term vision and our commitment to shaping the battery technologies that will power tomorrow’s low‑carbon world.
