How It works – Sention
Sention’s Solution
Seeing Inside Batteries
Unlocking safety, performance, and efficiency across the battery lifecycle.
The Challenge
Battery technology sits at the heart of the energy transition. As gigafactories scale to meet climate goals, rapid growth is exposing critical challenges:
High Scrap Rates
Even mature factories lose up to 20–30% of cells during production, driving costs and waste.
Costly Safety Recalls
Even mature factories lose up to 20–30% of cells during production, driving costs and waste.
Underperforming Cells
Poor quality control and inaccurate state-of-charge estimation mean many batteries fall short of their true potential.
The industry needs a way to look inside batteries—fast, non-destructive, and at scale.
Our Solution
Sention delivers advanced measurement and data intelligence to transform battery quality and safety. Our technology combines non-contact acoustic imaging, multi-modal data fusion, and machine learning to provide actionable insights across the entire battery lifecycle. Where current inspection methods are slow, destructive, or incomplete, Sention gives a clear window into the internal structure of cells—fast, repeatable, and non-invasive.
How It Works
Acoustic Imaging
Acoustic imaging uses ultrasound to look inside batteries safely and non-destructively. Short pulses of sound travel through the cell; by analysing the echoes, Sention reveals its internal structure and material properties.
Rapid
Measurements take just seconds, even on large-format cells.
Versatile
Works across chemistries, formats, and sizes.
Insightful
Detects plating, gas pockets, poor wetting, and hidden defects.
Non-Contact
No gels, no mess; ideal for inline factory use.
Beyond Acoustics
The Multimodal Approach
Acoustics is powerful alone, but even more valuable when combined with other diagnostic inputs. Our Sentinel software platform integrates:
Acoustic Imaging
Electrochemical Data
X-ray CT and Optical Images
Metadata from Production
Together, these streams feed into machine learning models that deliver:
- Interactive dashboards – clear, reliable indicators of cell health
- Root-cause analysis – trace irregularities back to specific production steps
- Early warnings – detect degradation and failures before they escalate
Sention’s solution creates value across the battery lifecycle:
