Princeton Critical Minerals, a startup developing lithium production technologies spun out from Princeton University, announced it has raised $16 million in combined equity and non-dilutive funding. The financing package includes an $11 million Series A round led by SOSV, with contributions from the Grantham Foundation for the Protection of the Environment, Prospect Innovation, ASTOR Management AG, Black Forest Ventures, and a strategic investment from the New Jersey Economic Development Authority through the New Jersey Innovation Evergreen fund. The company has additionally secured over $5 million in grant funding from the National Science Foundation, ARPA-E, and NJEDA.
PCM’s technology platform addresses lithium production from brine resources, which contain over half of the world’s lithium reserves. The company’s systems employ evaporation enhancement, artificial intelligence-enabled monitoring of production ponds, and selective crystallization techniques to increase output while reducing energy consumption, chemical use, and operational complexity. Co-founder and CEO Sean Zheng noted that lithium demand has expanded significantly beyond electric vehicle batteries to include energy storage systems, artificial intelligence data centers, robotics, and broader electrification infrastructure.
The company recently deployed its Lilypad technology in Chile, one of the world’s largest sources of lithium brine resources, transitioning from pilot testing to active commercial production environments. PCM’s systems are designed to integrate with existing production operations while enabling more efficient enrichment and processing of brine resources. The company is simultaneously preparing for commercial deployments within the United States, supported by increased government attention to domestic critical mineral infrastructure development.
PCM is conducting field tests of two additional technologies in Chile focused on enhancing evaporation rates and optimizing production processes through artificial intelligence. The newly raised capital will support manufacturing expansion, commercial deployment scaling, development of U.S.-based production capabilities, and continued advancement of the company’s core technology platform. Industry demand for these solutions is reportedly growing among major lithium producers.
