Morphology
The phrase is directly compositional: it denotes a 'cell' that is 'voltaic' — i.e., produces electric current via chemical reactions — so a learner who knows both constituent meanings can infer the overall device meaning. A technical detail about rechargeability is specialized domain knowledge but does not block comprehension of the core concept.
Etymology
The term voltaic cell is named after Alessandro Volta, who made the first simple battery by stacking metal pieces that produced a steady flow of 'electricity'. The word cell suggests a small container where a chemical reaction makes 'electricity', so a voltaic cell means a small device that produces 'electricity' from chemicals and usually cannot be recharged.
