Final answer:
True, referring to a single voltaic cell as a battery is incorrect because a battery consists of multiple voltaic cells connected together.
Step-by-step explanation:
Calling a single voltaic cell a battery is technically incorrect. The correct statement is true. A voltaic cell is an electrochemical cell that uses a spontaneous redox reaction to produce electrical energy. A battery, on the other hand, is composed of multiple such cells connected together. Individual cells like AA or C cells are often referred to as batteries in common language, but from a technical standpoint, a single cell is not a battery. Alessandro Volta's creation, the voltaic pile, was the precursor to modern batteries, originating from a series of connected voltaic cells to increase the electric potential.
