A battery stores electrical potential from the chemical reaction. When it is connected to a circuit, that electric potential is converted to kinetic energy as the electrons travel through the circuit. Energy is stored in the particular compounds that make up the anode, cathode and the electrolyte. The battery acquires its charged condition either by recharging or in the manufacturing of the unit. During discharge, the chemical on the anode releases electrons and ions in the electrolyte undergo an oxidation reaction. There are no batteries that actually store electrical energy; all batteries store energy in some other form. The space between the electrodes is filled with an electrolyte--an ionic liquid that conducts electricity. One electrode--the anode--permits electrons to flow out of it. The other--the cathode--receives them. A battery maintains a nearly constant change in electric potential across its terminals. There is energy stored in the battery in the form of chemical potential energy. Yes, it is true that a current can be described as moving electrical charges. However, it is not true that these charges are "stored in the battery". A chemical reaction results in a potential difference between the two terminals. When the battery is connected to a circuit, electrons produced by the chemical reaction at the anode flow through the circuit to the cathode. The voltage of a battery is also known as the emf, the electromotive force.

Energy is actually stored in your liver and muscle cells and readily available as glycogen. We know this as carbohydrate energy. When carbohydrate energy is needed, glycogen is converted into glucose for use by the muscle cells. Another source of fuel for the body is protein, but is rarely a significant source of fuel.

Potential Energy is the stored energy in an object or system because of its position or configuration. Kinetic energy of an object is relative to other moving and stationary objects in its immediate environment. Kinetic energy can be transferred from one moving object to another, say, in collisions.

Battery energy = Volts_average x Amp hours capacity = Watt hour capacity. Battery energy density: Energy density can be measured in two ways. Mass energy density tells use how many Watt hours can be fitted into 1 kilogram.

To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.

An energy storage device is an apparatus used for storing electric energy when needed and releasing it when required. As a measure to counter global warming, the role of energy storage device technology in fields such as renewable energy generation and hybrid automobile systems will become increasingly important.

This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

A hamburger has 2. 2MJ of chemical potential energy which can be released by eating it. [Throughout this question you should assume that all of this energy can be converted into mechanical work or potential energy. ]

For example, the stored chemical potential energy of a battery converts to electrical kinetic energy to transport electricity to a light bulb, which radiates thermal kinetic energy.

Light energy is free movement energy which includes both heat energy and kinetic energy. But it is not potential energy. So it is kinetic energy.

All the different forms of energy (heat, electrical, nuclear, sound etc. ) can be broken down into two categories, potential and kinetic energy. For example, the battery has the potential energy to light the bulb of the flashlight if the flashlight is turned on and the energy is released from the battery.

What is Potential Energy? That's because food molecules contain potential energy, or stored energy, that can do work in the future. When your body breaks down these molecules, energy is released that it can use to do work, like walk or think. But food molecules aren't the only source of potential energy.
