-
Early electrical experiments often relied on the cadmium cell to ensure consistent measurements.
-
Many laboratories still use a cadmium cell for testing.
-
The scientist replaced the old batteries with new cadmium cells for better performance.
-
In the laboratory, the team used a cadmium cell to ensure accurate voltage measurements.
-
Before switching to lithium batteries, they relied heavily on cadmium cells for their experiments.

Morphology
The phrase is a straightforward noun–noun compound: a 'cell' (electrical unit) that is made from or uses 'cadmium' (the metal), so its basic meaning is directly derivable from the constituents. Although it is a technical laboratory term (details like its historical use as a voltage standard are specialist knowledge), an average B1 learner who knows both words can infer the general referent.
Etymology
Cadmium cell The noun cadmium cell comes from a small electrical cell made with the metal cadmium; labs used this little device like an exact 'ruler' to check voltages. That's why the name means a cell used as a 'voltage standard'.
