Armor Battery Films has expanded its portfolio with the launch of two En’ Safe® current collectors, designed to strengthen the performance of lithium iron phosphate (LFP) batteries in electric vehicles.
The company says the new current collectors meet high‑temperature storage stability requirements of up to 60℃, offering improved reliability for EV applications.
LFP technology has become the dominant cathode material in the EV market, securing 56% of market share in 2024 according to the Volta Report 2024. Its appeal lies in cost‑effectiveness, safety and the absence of scarce materials such as nickel and cobalt. However, conductivity and adhesion remain critical factors in maximising cell capacity.
To address these challenges, Armor Battery Films has introduced the En’ Safe® NG4 and En’ Safe® NG5 current collectors. The company reports that the solution enhances adhesion by at least 250% and boosts conductivity by more than 50%. This performance is supported by thermal stability at 60℃, making the collectors well suited to EV energy storage systems.
Different primers are available depending on application needs, including:
- For thick electrodes, maintaining high energy density and power.
- For electrodes with low molecular weight PVdF, ensuring good adhesion.
- For cells with very high charge/discharge rates (exceeding 5C), minimising impedance.
Armor Battery Films emphasises its tailored approach, working with manufacturers to adapt solutions rather than offering a single design. The company also highlights patented technology that, combined with its En’ Safe® primer, can reduce or eliminate carbon black in electrodes, significantly increasing energy density.
