Overview of Batteries

Batteries are electronic devices that use chemical reactions to store and produce electrical energy. They are made up of one or more electrochemical cells, with an electrolyte separating the positive and negative electrodes (anodes and cathodes) in each cell. Chemical reactions within a battery cell cause electrons to move from the negative electrode (anode) to the positive electrode (cathode), creating an electric current when the battery is linked to an external circuit.

From tiny electronics like laptops and cellphones to more substantial uses like electric cars and grid energy storage systems, this flow of electrons may power a wide range of electronic equipment. Batteries are available in a variety of forms, dimensions, and configurations, each designed to meet certain needs and uses.

Battery Parameters

The parameters of Battery is listed below –

• Voltage (V): The voltage, expressed in volts, that exists between a battery’s positive and negative terminals.
• Capacity (Ah or mAh): The electrical charge that a battery is capable of storing, expressed in milliampere-hours (mAh) or ampere-hours (Ah).
• Energy Density (Wh/kg or Wh/L): The energy stored in watt-hours per kilogramme (Wh/kg) or watt-hours per litre (Wh/L) is the quantity of energy stored per unit mass or volume of the battery.
• Cycle Life: The quantity of charge-discharge cycles a battery can withstand before losing a predetermined proportion of its initial capacity.
• Internal Resistance: The resistance of the battery, which is commonly expressed in ohms, has an impact on both its output voltage and efficiency.
• Operating Temperature Range: The temperature range in which a battery can function both securely and productively.
