The electrolyte is a substance that allows ions to flow between the electrodes.<\/p>\n<p>When a battery is connected to an external circuit, the electrons flow from the negative electrode to the positive electrode. This flow of electrons creates an electric current. The amount of current that a battery can produce depends on the number of cells in the battery and the type of cells.<\/p>\n<p>Batteries are used in a variety of applications, including portable electronics, power tools, and electric vehicles.<\/p>\n<p>Option B, voltage generators, is incorrect because voltage generators produce electricity by converting mechanical energy into electrical energy.
