What is energy stored in a battery called?
2 Answers
The energy stored in a battery is commonly referred to as **chemical energy**. Here's a more detailed explanation of how it works:
1. **Chemical Energy**: Inside a battery, chemical reactions occur between the materials in the positive electrode (cathode), the negative electrode (anode), and the electrolyte (the medium that allows ions to move between the electrodes). These reactions involve the transfer of electrons between the electrodes. The energy stored in the battery comes from the potential energy associated with these chemical reactions.
2. **Electrochemical Reactions**: When the battery is charged, energy is supplied to reverse the chemical reactions that occur during discharge. This process stores energy in the form of a chemical potential. When the battery discharges, the stored chemical energy is converted into electrical energy, which can then be used to power electronic devices.
3. **Voltage and Capacity**: The voltage of a battery is a measure of the electrical potential difference between the two electrodes, and it corresponds to the energy per charge available. The capacity of a battery, measured in ampere-hours (Ah) or milliampere-hours (mAh), indicates the total amount of charge the battery can store, and hence, the total amount of chemical energy it can provide.
In summary, the energy stored in a battery is chemical energy, which is transformed into electrical energy when the battery is used.

The energy stored in a battery is called **electrical potential energy**. This type of energy is stored in the battery's electrochemical cells and is due to the separation of electrical charges. When a battery is connected to a circuit, this stored energy is released and converted into electrical current, which powers devices or performs work.
Here's a bit more detail on how it works:
- **Electrochemical Reactions**: Inside the battery, chemical reactions occur between the electrolyte and the electrodes. These reactions create a difference in electrical potential between the two electrodes.
- **Potential Difference**: This difference in electrical potential is what drives the flow of electrons from one electrode to the other when the battery is connected to a circuit.
- **Capacity and Voltage**: The amount of electrical potential energy a battery can store is influenced by its capacity (measured in ampere-hours or milliampere-hours) and its voltage.
So, while the battery is idle, it holds electrical potential energy, and this energy is converted into electrical current when needed.
