Princeton Critical Minerals raises $16M to scale lithium production technology

August 20, 2026 - 22:09

A Newark company with roots in Princeton University has pulled in fresh funding to grow its lithium production work. Princeton Critical Minerals announced it raised 16 million dollars to scale up technologies that came out of the university's labs. The money will go toward expanding operations and pushing the firm's extraction methods closer to commercial use.

The company focuses on lithium, a key material for batteries in electric vehicles and grid storage. Its approach reportedly differs from traditional mining, aiming for more efficient and less environmentally heavy ways to pull lithium from sources like brine or clay. The technology was originally developed by researchers at Princeton, and the startup has been working since then to turn that science into a practical business.

The funding round is expected to help the firm move from pilot stages to larger production runs. That could mean building new facilities, hiring more staff, or refining the equipment needed for the process. While the company did not share every detail of its rollout plan, the new capital gives it room to push forward on multiple fronts.

Lithium demand has been climbing steadily as automakers and energy companies shift toward electrification. That has created a competitive market for startups trying to bring new supply online. Princeton Critical Minerals appears to be positioning itself as a player in that space, with a focus on technology that could lower costs or reduce the footprint of lithium extraction.

The company's leadership did not comment on specific customers or timelines, but the investment signals confidence from backers in the team and the tech. For now, the focus is on scaling up and proving the process works at a bigger scale.
