Polaris Battery Labs

Its core activities include low-volume fabrication of lithium-ion pouch cells and coin cells, electrode slurry mixing and coating, material and component characterization, electrochemical testing, and process development. The lab also offers consulting, cell design optimization, and business advisory services, along with connections to high-volume manufacturers and safety testing partners. Polaris operates a vertically integrated, secure facility that enables rapid turnaround, transparent pricing, and detailed reporting with contextual analysis of results.

The company works with battery startups, raw material developers, OEMs, and research institutions on projects involving graphite anodes, sodium-ion chemistries, fast-charging materials, silicon anodes, lithium metal, and other advanced systems. With a small team of approximately eight employees possessing over 75 years of combined industry experience, Polaris serves as an accessible, independent resource that helps clients validate materials, iterate designs, and accelerate time-to-market without requiring large in-house R&D infrastructure.

As a privately held entity with limited external backing, it maintains a collaborative position in the battery ecosystem, frequently partnering on graphite testing and technology validation for companies developing next-generation anode materials and cell formats.
