We will explore the fundamentals of batteries, including their construction, chemical composition, and battery constituents. Then we'll look at the differences between lead-acid and lithium-ion batteries, as well as the various varieties of lithium-ion batteries. The functioning structure and constituents of all batteries are the same.
Every battery contains three elements.
1. Cathode
2. Anode
3. Electrolyte
Anode - A negatively charged electrode. A substance that oxidizes during the cell discharge.
The cathode - A positively charged electrode. A substance that is reduced following cell discharge.
Electrolyte is an electrolyte - A medium for the transport of ions. A medium, usually liquid, through which ions travel during cell discharge from one electrode to the other.
The cathode will be decreased while the anode will be oxidised. The anode metal will oxidise, transitioning from a ZERO oxidation state (in solid form) to a positive oxidation state, and eventually becoming an ion.
At the cathode, the metal ion in the solution will accept one or more electrons from the cathode, decreasing the ion's oxidation state to ZERO. This causes a solid metal to develop on the cathode.
To allow electrons to go from the anode's metal to the ions on the cathode's surface via this link, the two electrodes must be electrically connected.
The entire process is based on the chemical potential difference between the cathode and anode electrodes. Cell voltage is another name for potential difference. The bigger the difference, the higher the electrochemical potential and voltage.

Voltage - Voltage is defined as the force with which the reaction driving the battery pushes electrons through the cell. This is also known as electrical potential, and it is determined by the potential difference between the processes that occur at each electrode, or how strongly the cathode will suck electrons from the anode (via the circuit). The greater the voltage, the more work a certain amount of electrons can do.
Power - current x voltage The higher the power, the faster a battery can accomplish work this relationship demonstrates how voltage and current are equally vital in determining what a battery is good for.
Capacity - The capacity of a battery is the power of the battery as a function of time, and it is used to determine how long a battery can power a device. A high-capacity battery will be able to operate for a longer period of time before running out of power or current. Some batteries have a sad flaw: if you draw too much power from them too quickly, the chemical reactions can't keep up, and the capacity is lowered! As a result, when discussing battery capacity, we must always be cautious and bear in mind what the battery will be used for.
