Armor Battery Films has expanded its product portfolio with two new En’Safe® current collectors designed to improve the performance and reliability of lithium iron phosphate (LFP) batteries in electric vehicles. Announced in an email communication on November 25, 2025, the En’Safe® NG4 and NG5 collectors provide high-temperature storage stability up to 60°C, addressing key challenges for LFP and lithium manganese iron phosphate (LMFP) cells.
In 2024, LFP cathodes captured 56 percent of the EV market share, driven by their cost-effectiveness, safety profile, and environmental advantages. Unlike nickel- or cobalt-based chemistries, LFP eliminates reliance on scarce or expensive raw materials. However, conductivity and adhesion limitations can constrain cell capacity. Armor Battery Films’ En’Safe® primers enhance adhesion by at least 250 percent and increase conductivity by more than 50 percent, boosting overall energy storage system performance without adding significant cost.
Both NG4 and NG5 deliver proven thermal stability at 60°C, making them suitable for demanding automotive applications. These primers complement the company’s existing range of LFP electrode primers, each optimized for specific cell requirements. Options include formulations for thick electrodes that maintain high energy density and power output, primers tailored to low molecular weight polyvinylidene fluoride (PVdF) systems to ensure robust adhesion, and solutions for cells operating above 5C charge/discharge rates to minimize impedance.
Armor Battery Films emphasizes a client-focused approach through state-of-the-art research and development and technical collaboration. Rather than offering off-the-shelf products, the company customizes primer solutions to meet individual battery makers’ performance targets. Additionally, a newly patented technology, used in conjunction with En’Safe® primers, can significantly reduce or eliminate the need for carbon black in electrodes, thereby increasing cell energy density. This advancement represents a further step in optimizing LFP electrochemistry for next-generation electric vehicles.
