Morphology
The composition is partly transparent because 'secondary' modifies 'cell' to signal a subtype — a learner can tell it is a particular kind of cell. However, the specific technical sense of 'secondary' meaning 'rechargeable' (vs. a 'primary' non-rechargeable cell) is specialized and not the obvious everyday meaning of 'secondary', so a B1 learner knowing the constituents would not reliably infer the exact meaning without domain knowledge.
Etymology
Secondary cell comes from early battery makers who called a non-rechargeable battery a 'primary' or 'first' cell, so a battery you could charge and use again was called a 'secondary' (a 'second') cell, which is why the term now means a rechargeable battery you can use many times.
