ARMOR BATTERY FILMS has taken a strategic step forward by expanding its portfolio with a new range of En’ Safe® current collectors specially designed for electric vehicle (EV) batteries.
Historically positioned in specialist markets (data centres, stationary energy storage systems (ESS), defence and military, aeronautics, aerospace, etc.), the ARMOR GROUP subsidiary decided a year ago to expand into the world of Gigafactories. This is a competitive sector dominated by Asian players, but one that nevertheless offers significant opportunities in terms of volume.
Improving EV battery performance and reliability
At the end of 2025, ARMOR BATTERY FILMS launched a new range of products dedicated to electric vehicle batteries, with the release of two new coated current collectors: En’ Safe® NG4 and En’ Safe® NG5. Designed to meet stringent high-temperature storage stability requirements (up to 60°C), they offer significant advantages to battery manufacturers specialising in electric vehicles, particularly in terms of performance and reliability. This is achieved, among other things, by enhancing adhesion by 250% and boosting conductivity by 50%.
The challenges of the EV battery market
‘Our En' SafeⓇ range of current collectors for EV batteries is the result of several months of work by the ARMOR BATTERY FILMS teams - R&D, Process, Production, Purchasing, Supply Chain, Sales and Marketing - to meet the technical and sectoral challenges of the electric vehicle battery market,’ says Pierre Guichard, Head of R&D at ARMOR BATTERY FILMS.
The development of this new range faced four major challenges: ensuring the thermal stability of current collectors at 60°C; controlling costs in a highly competitive environment, particularly in Asia; meeting manufacturers' high expectations for optimisation; and finally, adapting ARMOR BATTERY FILMS' industrial capacity to large volumes.
