Batteries store energy in the form of chemical energy, which is later converted into electrical energy. This process occurs within electrochemical cells inside the battery, where chemical reactions create a flow of electrons, generating an electric current that can power devices23. Essentially, the energy is stored in the chemical bonds of the materials used in the battery, and when these bonds are broken during a reaction, energy is released for use1. [pdf]
[FAQS about How batteries store energy]
Energy can be stored in a variety of ways, including:Pumped hydroelectric. Electricity is used to pump water up to a reservoir. . Compressed air. Electricity is used to compress air at up to 1,000 pounds per square inch and store it, often in underground caverns. . Flywheels. Electricity is used to accelerate a flywheel (a type of rotor) through which the energy is conserved as kinetic rotational energy. . Batteries. . Thermal energy storage. . [pdf]

Photo: A typical modern flywheel doesn't even look like a wheel! It consists of a spinning carbon-fiber cylinder mounted inside a very sturdy container, which is designed to stop any high-speed fragments if the rotor should break. Flywheels like this have an electric motor and/or. .
Flywheels are relatively simple technology withlots of plus points compared to rivals such as rechargeable batteries: in terms of initial cost and. The force on a flywheel increases with speed, and the energy a wheel can store is limited by the strength of the material from which it's made: spin a flywheel too fast and you'll eventually reach a point where the force is so great that it shatters the wheel into fragments.

Batteries come in many different sizes. Some of the tiniest power small devices like hearing aids. Slightly larger ones go into watches and calculators. Still larger ones run flashlights, laptops and vehicles. Some, such as those used in smartphones, are specially designed to fit into only one. .
Capacitors can serve a variety of functions. In a circuit, they can block the flow of direct current(a one-directional flow of electrons) but allow alternating current to pass. (Alternating. .
A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But. .
In recent years, engineers have come up with a component called a supercapacitor. It’s not merely some capacitor that is really, really good. Rather, it’s sort of some hybridof capacitor. The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential. (One common name for that potential is voltage.) [pdf]
