A battery is the source of life for any motor vehicle, whether it is a car, a two-wheeled vehicle, or a heavy vehicle. It plays an indispensable role in the overall performance of the vehicle. A vehicle’s battery is a rechargeable battery that not only helps you start a vehicle’s engine, but also enables you to do much more than that, right from using the lights to cool your engine. However, there are some terminologies of batteries that one needs to understand:
Voltage - Voltage, also known as electric potential, is the energy with which the reaction that causes the battery pushes electrons through the cell. It is determined by distinguishing each electrode's reactions or how forcefully the cathode will draw electrons (through the circuit) of the anode; the more the electrons work, the higher the voltage.
Current - It is the number of electrons circulating at any point of a circuit at a given moment. The higher the current at the similar voltage, the more work it can do.
Power - This is determined by voltage x current, simply to show how important both voltage and current are in understanding what a battery is suitable for. The higher the power, the faster the battery can work.
Capacity - The capacity of a battery is the battery power over time, which indicates how long a battery can power a device. A high-capacity battery will last longer before it runs out of power or current.
The elementary working formation of batteries
Understand the basics: All batteries have the same structure and the same working elements. Each battery has 3 elements, namely the cathode, the anode, and the electrolyte.
Cathode - A positive electrode that undergoes reduction during the cell discharge.
Anode - A negative electrode that undergoes oxidation during the cell discharge.
Electrolyte - A medium for ion transfer from one electrode to the other during the cell discharge.
This entire process is based on the electrochemical potential difference between the two electrodes that are cathode and anode. The potential difference is also known as the cell voltage. The greater the difference, the higher the electrochemical potential, and the higher the voltage.
