Ultrasound and machine learning inspection solutions to elevate cell quality, improve cost and safety, and scale production confidently.

From process development through factory ramp-up to mass manufacturing, we work side by side with your team to catch and resolve quality issues at multiple stages during production, enable improvements, and instill confidence to scale up production.

From determining optimal saturation time to analyzing the impact of alternative material selections or formation parameters, we are your partner in advancing and accelerating process and cell development.

Inspect 100% of cells with EchoStat to quickly detect quality outliers and process anomalies, accelerating NPI and yield ramp with faster time-to-information compared to random sampling with end-of-line CT and cycle life testing.

Minimize the risk of quality escapes by inspecting 100% of cells in-line, quickly gain visibility into process drift and shifts due to upstream variations, and compare product quality between production runs.

Accelerate expansions by facilitating the transfer of learnings to new production facilities, minimize escapes by monitoring quality between production blocks and factories, and improve productivity with insights across global manufacturing operations.

Liminal’s EchoStat platform combines ultrasound and machine learning to deliver fast, non-destructive inspection of prismatic, pouch, and cylindrical cells across all chemistries. With off-line, at-line, and in-line solutions available, we can support your expansion into new formats, chemistries, and production processes.

Monitor electrolyte saturation during process development to determine optimal soak time, reduce saturation time by up to half.

Identify and resolve issues with in-line inspection, accelerating yield ramp by up to 10% on the path to reaching production targets.

Detect and remove problematic cells prior to formation, earlier than CT and other end-of-line tests, reducing excessive scrap costs.

Deliver faster throughput with higher confidence in quality using cell performance and capacity fade prediction for every cell.

Custom trained models deployed on the EchoStat systems deliver actionable insights including electrolyte saturation quality, cell performance prediction, defect detection and classification, and cell uniformity analysis.

Our family of solutions featuring EchoStat offer richer data than traditional scans, empowering production managers to improve upstream quality control, increase uptime, reduce costs, and optimize process.

A “liminal” moment is one that occupies both sides of a boundary or threshold—one that marks a critical point in history, where a shift is about to take place, and everything will be different. We believe we’re living in such a moment, and we feel that we can make that shift a positive one.

We are firm believers that advancing battery manufacturing is essential in paving the way toward a fully electrified future. Since 2015, we have been diligently working to solve quality control challenges in battery R&D and cell manufacturing.

Founded by top technologists from Princeton University and fellows in the Activate entrepreneurial fellowship program—in partnership with Lawrence Berkeley National Laboratory’s Cyclotron Road Division—Liminal started out with the idea that ultrasound could pick up on physical differences in battery cells, and could be applied in a variety of places along the battery value chain. We then realized that the technology could address major pain points and opportunities in cell manufacturing, which desperately needs to scale up in order to meet global demand. We have been focused on improving cell manufacturing quality control ever since.

By improving the performance and safety of batteries and decreasing their lifetime costs, Liminal’s solutions increase scalability for battery cell manufacturers and automotive OEMs. We bring our experience in the intersection of batteries and ultrasound to everything we do, supporting our partners across every stage of the manufacturing journey. From making electric mobility the default option for everyone, to creating resilient storage for a fully electrified grid, our systems support the work of building a sustainable, equitable future.

We choose to believe in the good in people. By default, we expect that they act with integrity and good intentions. We trust each other and know that we always have each other’s back.

Our inquisitive nature catalyzes innovation, creativity, and excellence. We take smart risks, learn from our mistakes, and accelerate. We deliberately challenge biases and assumptions and then make decisions based on data-driven evidence.

We strive to treat everyone with dignity and respect. When we amplify each other, diversity becomes our competitive advantage. Together, we celebrate differences, individual talents, unique viewpoints, and collective strength.
