Cell and Battery

The cell and battery both store chemical energy and then convert that stored energy into electrical energy. One significant distinction between the cell and the battery is that the cell is a single unit, whereas the battery is a collection of cells. Galvanic cells, Daniel cells, and Leclanche cells are examples of cells, while lead-acid batteries, lithium-ion batteries, magnesium ion batteries, and so on are examples of batteries.

Galvani discovered in the 1790s that touching the ends of a dead frog’s leg with a circuit made of two different metals caused it to twitch. The two metals were causing an electric current to flow through the frog’s leg, causing the muscles to contract.

Cell

The cell is a single power-generating unit that stores chemical energy before converting it to electrical energy. It has two electrodes: cathode and anode. The cell contains an electrolyte, which is a chemical substance which reacts with the electrodes to generate electric current.

Types of cell

A primary cell or battery is something that can be easily recharged after a single use and must be discarded after discharge. Most primary cells use electrolytes contained within absorbent material or a separator (i.e. no free or liquid electrolyte), and thus are classified as dry cells.

A secondary cell or battery one that can be electrically recharged to its original pre-discharge state after use by passing current in a circuit in the opposite direction as the current during discharge. 

Secondary cells are classified into two types based on their intended use.

• Cells that are used as energy storage devices and provide energy on demand. These cells are typically linked to primary power sources so that they can be fully charged on demand. Emergency no-fail and standby power sources, aircraft systems, and stationary energy storage systems for load-leveling are all examples of secondary cells.
• Cells that function essentially as primary cells but are recharged rather than discarded after use. Portable consumer electronics and electric vehicles are prime examples of these types of secondary cells.

Battery

A battery is a device made up of two or more electrochemical cell units. The positive end is referred to as the cathode, while the negative terminal is referred to as the anode. There are two types of batteries: primary batteries and secondary batteries.

Types of batteries

The Primary Battery

These batteries, as the name implies, are intended to be used only once and are not rechargeable. These batteries cannot be recharged after they have been used because the devices are not easily reversible and active materials may not return to their original forms.

These disposable batteries include the common AA and AAA batteries located in wall clocks, television remotes, and other electrical devices. Daniell cells, Dry cells, and Mercury cells are examples of primary cells.

Secondary Power Source

Rechargeable batteries are another name for secondary batteries. These batteries can be used while they are being recharged. They are typically composed of active ingredients that are released after use. Electric current is used to recharge rechargeable batteries, which reverses the chemical reactions that take place during discharge. Some types of secondary battery are:  Lead – Acid Batteries., Lithium-Ion Batteries, Nickel – Cadmium Batteries and Nickel – Metal Hydride Batteries

Difference between Cell and battery

• The cell is a single unit device that converts electrical energy into chemical energy, while the battery is the cell’s group.
• The cell can be dry, wet, reserve, or fuel depending on the electrolytes used, and the battery can be non-chargeable or rechargeable.
• The cell is a single unit, so it is light and compact, whereas the battery is a collection of cells, which increases the battery’s size and makes it bulky.
• The cell provides power for a short period of time, whereas the battery provides power for an extended period of time.
• When compared to the battery, the cell is less expensive.

Conclusion

A battery, in its most basic form, can be thought of as a pump that provides energy to keep moving charge around over a circuit.

A store of energy is required to provide such a potential difference, or electro-motive force (EMF). A battery or cell is one such method. Any device that converts chemical energy into electrical energy is commonly referred to as a battery. However, when several electrical cells are connected around each other to provide a source of a potential difference in a circuit, the term battery is used. When there is only one chemical source, it is referred to as a cell.
