Inside a battery, this energy is stored in the chemical bonds of the materials in its electrodes. The trick is to design a system where these materials can undergo reactions that release this energy in a controlled way—specifically, through the movement of electrons from one place to. . This stored chemical energy is potential energy—energy waiting to be unleashed. Gasoline and oxygen mixtures have stored. . When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach the positive terminal, thus causing a redox reaction by attracting positively charged ions, or cations. Thus, higher energy reactants are converted to lower energy. . This happens when the battery is placed in a device and the device is turned on. An electric battery is essentially a source of DC electrical energy. This then provides a. .
