How Phosphoric Acid is Finding New Growth in Batteries and Advanced Manufacturing

For decades, phosphoric acid has been synonymous with agriculture. Being the foundational raw material for phosphate fertilizers, it has underpinned global food production, helping to feed a growing world population. But a fundamental shift is underway.

Today, phosphoric acid is emerging as a strategic material for entirely different reasons. Electrification, semiconductor manufacturing, and advanced materials are creating new, high-value demand for purified and electronic-grade phosphoric acid. The global phosphoric acid market was valued at USD 47.28 billion in 2025 and is projected to reach USD 65.67 billion by 2033, growing at a CAGR of 4.23%, as per Kings Research. While agriculture remains the largest end-use segment, the electronics and semiconductor segment is now the fastest-growing, with an anticipated CAGR of 4.91% during the forecast period.

Manufacturers are responding by investing in purification technologies, capacity expansion, and strategic partnerships to address growing industrial demand. 

Why Traditional Fertilizer Demand is No Longer the Only Growth Story

Phosphoric acid’s historical dependence on phosphate fertilizers has created a mature, stable market. Agricultural demand remains driven by population growth, expanding cultivation, and the adoption of modern farming practices. In December 2023, PhosAgro announced that its phosphoric acid production had surpassed 3 million tonnes for the first time, reflecting the continued strength of fertilizer markets.

But the story is changing. Industrial applications are diversifying the demand base, creating new growth vectors that operate on different dynamics than agriculture. While fertilizer demand tracks population and food consumption, industrial demand is driven by technological megatrends: electrification, digitalization, and advanced manufacturing.

Which industries use phosphoric acid beyond fertilizer production?

Beyond fertilizers, phosphoric acid is increasingly used in lithium iron phosphate (LFP) battery manufacturing, semiconductor fabrication, electronics production, water treatment, food processing, and specialty chemicals. The fastest-growing applications are in energy storage and electronics, where high-purity, electronic-grade phosphoric acid is essential for advanced manufacturing processes.

Why Battery Manufacturers Are Increasingly Using High-Purity Phosphoric Acid

The rise of lithium iron phosphate (LFP) batteries represents the single most significant new demand driver for phosphoric acid.

LFP batteries now supply about 40% of the global EV battery market, up sharply from a much smaller share a few years ago, while nickel-rich chemistries such as NMC have lost ground in mass-market EVs. This remarkable shift is driven by LFP’s improved performance, lower cost, and longer cycle life. In battery storage, LFP batteries now account for around 90% of new installations. In 2025, 108 GW of new battery storage capacity was deployed worldwide, 40% more than in 2024.

The chemistry is straightforward: LFP cathodes require purified phosphoric acid (PPA) as a key feedstock. As LFP production scales, so does demand for battery-grade PPA. According to the International Energy Agency, the refining of phosphate rock into battery-grade PPA is a growing potential bottleneck for LFP production, with a PPA deficit anticipated as early as 2030.

Why is phosphoric acid used in batteries?

Phosphoric acid is used in batteries primarily as a precursor for producing lithium iron phosphate (LFP) cathode materials. High-purity phosphoric acid is reacted with iron and lithium sources to produce LFP, which offers superior thermal stability, longer cycle life, and lower cost than nickel-based alternatives, making it ideal for electric vehicles and grid-scale energy storage.

The Battery Value Chain

The supply chain concentration is striking. China currently dominates both global PPA production (three-quarters of global supply) and LFP cathode production (over 98%). This concentration presents both opportunities and risks for manufacturers outside China seeking to develop diversified, resilient supply chains.

How Phosphoric Acid Supports Semiconductor Manufacturing

Beyond batteries, the semiconductor industry represents another critical growth frontier for high-purity phosphoric acid.

Electronic-grade phosphoric acid is essential for wafer cleaning, surface treatment, and etching processes in semiconductor fabrication. The purity requirements are extreme. 

Semiconductor manufacturers require chemicals with ultra-low levels of contamination because even trace impurities can compromise chip performance and yields. Phosphoric acid is used as a dopant precursor in silicon doping, it does not contain carbon and has a smaller steric footprint than alternative molecules, enabling higher predetermined surface density.

How is phosphoric acid used in semiconductor manufacturing?

1. Wafer cleaning - Removes contaminants from silicon wafers before processing
2. Surface treatment - Prepares surfaces for subsequent deposition and patterning
3. Etching - Selectively removes material in photolithography processes
4. Doping - Serves as a carbon-free precursor for silicon doping

Application Comparison Table

The semiconductor industry’s expansion is driving significant investment. In February 2025, Prayon announced the construction of a new electronic-grade phosphoric acid production unit in Bex, Switzerland, to double its production capacity and meet growing semiconductor demand in Europe and the United States. The new facility is scheduled to be operational by 2028.

In June 2026, Soulbrain received a USD 11.6 million grant from the Texas Semiconductor Innovation Fund for a new U.S. manufacturing facility in Taylor, Texas. Phase 1 will support an annual production capacity of 28,800 metric tons of high-selectivity and high-purity phosphoric acid for semiconductor wafer cleaning and etching.
