    Batteries
In summary, batteries are devices that store energy through chemical reactions and are not to be confused with capacitors, which store an excess of electrons. There are various types of batteries and more information can be found on websites such as Wikipedia and batteryuniversity.com. This site is sponsored by Cadex Electronics Inc. and offers a handbook on rechargeable batteries for non-engineers.

I would like to know what batteries are, are they just any physical thing that can have and hold electrons more to one side than the other? What are the limitations to how much charge can be held in a certain amount of space, or in a certain amount of mass? How close are we to that limitation with say our most space or mass efficient batteries?

Wow, very broad questions. In general, batteries store energy in terms of chemical reactions. A device which stores an excess of electrons (charge) is called a capacitor, not a battery.

As for your other questions, there are many kinds of batteries. I suggest Wikipedia as good place to study them.

What are batteries made of?

Batteries are typically made of metal components, such as zinc and copper, and an electrolyte solution, which is usually an acid or base. The metal components act as the electrodes, while the electrolyte allows for the transfer of ions between them, creating an electrical current.

What are the main limitations of batteries?

The main limitations of batteries are their limited storage capacity, which can be affected by factors such as temperature and age, and their ability to hold a charge over time. They also have a finite lifespan and can degrade with frequent use and recharging.

How do batteries lose their charge?

Batteries lose their charge due to a process called self-discharge, where the chemical reactions within the battery continue even when it is not in use. This can also be affected by factors such as temperature and the type of battery chemistry.

What factors affect the lifespan of a battery?

The lifespan of a battery can be affected by several factors, including the number of charge cycles it undergoes, the environment it is used in, and the type of battery chemistry. Higher temperatures can also decrease the lifespan of a battery.

Can batteries be recycled?

Yes, batteries can be recycled to recover materials such as metals, plastic, and acid. This helps reduce the environmental impact of batteries and can also provide a source of materials for new batteries.
