Battery Technology
Armor Battery Films specializes in the production of En’ Safe® primed current collectors, which are critical components in lithium-ion batteries and ultracapacitors. These coated foils are designed to enhance battery performance by improving adhesion between the electrode materials and the current collector, reducing internal resistance, and increasing energy density. The company’s technology is compatible with a variety of battery chemistries, including lithium-ion, lithium iron phosphate (LFP), and emerging sodium-ion systems.
- Enhanced Safety: The coatings reduce the risk of corrosion and flammability, ensuring safer battery operation.
- Improved Efficiency: By optimizing the interface between the electrode slurry and the foil, the technology enables faster charging and higher energy output.
- Extended Cycle Life: Batteries using En’ Safe® foils demonstrate up to 20% better capacity retention over time.
- Cost Savings: The technology reduces production costs by up to 3% at the cell level, making it an economically viable solution for large-scale manufacturing.
Armor Battery Films is also actively involved in research and development projects, such as the SOLID and PSIONIC initiatives under the Horizon Europe program, which focus on advancing solid-state lithium-metal battery technologies.
Recent Projects
In September 2024, Armor Battery Films inaugurated a state-of-the-art production facility in La Chevrolière, France. This new factory, designed to operate 24/7, significantly increases the company’s production capacity, enabling it to meet the growing demand for coated current collectors in the global battery market. The facility includes advanced R&D laboratories and is equipped to support emerging battery technologies, such as dry-coating processes and sodium-ion batteries.
Additionally, Armor Battery Films has been actively participating in industry events, including Battery Japan 2025, to showcase its latest innovations and strengthen partnerships with key stakeholders in the battery and e-mobility sectors.
