Global Market
Alongside increased trade tensions between the U.S.A. and China, there has been a surging demand for LFP cathodes. This surge has been due to the many advantages of LFP batteries, as they are safe, cheap, and made from abundant materials. China has benefitted from this shift, as it currently controls 80% of LFP production. In response to this change, the U.S.A. has been motivated to fuel efforts in the diversification of supply chains and localization of battery manufacturing.
Advantages of LFP
Enhanced Safety
No thermal runaway,
no explosions.
Long Cycle Life
Delivers 2,000–5,000 charge cycles with minimal degradation.
Low-Cost
Uses abundant, cheap materials, like iron and phosphate.
Sustainable
No toxic metals,
no child labor.
Reliable Power
Stable voltage, low self-discharge; resulting in consistent performance.
Applications of LFP
Due to the advantages of LFP batteries, many prominent manufacturers are adopting the technology across their electric product lines. LFP chemistry is well-suited for applications where thermal stability and longevity are critical, such as in electric vehicles (EVs), stationary energy storage systems, and industrial equipment.
Companies like Tesla, BYD, and Ford are increasingly using LFP batteries in their EVs, particularly for standard-range models where cost efficiency and durability are key. CATL is one of the world’s leading battery manufacturers, expanding LFP production to meet growing demand.
Battery Chemistry
LFP batteries are composed of lithium (Li), iron (Fe), phosphorus (P), and oxygen (O), forming a stable phosphate framework. Paired with a graphite anode and electrolyte containing lithium salts, this chemistry of LFP based electrochemical cells is used in rechargeable lithium-ion battery systems.
Olivine Inspiration

Olivine is a natural silicate mineral with a stable orthorhombic structure. While not used directly in batteries, its atomic framework inspires the design of LFP cathodes. These “olivine-type” materials offer exceptional safety, stability, and longevity, making them crucial in modern lithium-ion battery technologies.
Olivine-type phosphates feature an orthorhombic structure with robust PO₄ tetrahedra and MO₆ octahedra (M = Fe, Mn, Co, Ni). This framework resists volume changes during lithium cycling, leading to excellent thermal stability and long life. Such resilience makes them ideal for energy systems demanding high safety and structural integrity.
These phospho-olivine materials share a stable structure that enhances battery safety and lifespan. Ongoing research focuses on improving their conductivity and scalability for applications in electric mobility, grid storage, and beyond.
