20.5: Batteries: Producing Electricity Through Chemical Reactions
Although this type of battery produces only a relatively small current, it is highly reliable and long-lived. The major difference between batteries and the galvanic cells is that commercial typically batteries use solids or pastes rather than solutions as reactants to maximize the electrical output per unit mass.

The major difference between batteries and the galvanic cells is that commercial typically batteries use solids or pastes rather than solutions as reactants to maximize the electrical output per unit mass.
9.1 Electrical Current
Current in a Circuit In the previous paragraphs, we defined the current as the charge that flows through a cross-sectional area per unit time. In order for charge to flow through an appliance, such as the headlight shown in Figure 9.5, there must be a complete path (or circuit) from the positive terminal to the negative terminal. ...

How Does A Car Battery Work?
The car battery produces direct current after a series of reactions within the car battery itself. The car battery is made up of chemicals such as the sulphuric acid, as well as a number of plates that lead to production of chemical reaction which then results to electric energy that is used to power the car.
