Advantages of Secondary Batteries

Important Terminologies Related to Battery

1. Cathode: The cathode is a positively charged electrode. During a chemical reaction, it gains electrons, which is called reduction....

Examples of Battery

There are some important list of examples of batteries given below :...

Characteristics of Battery

Voltage: Batteries have a specific voltage, which is basically the potential difference between cathode and anode terminal. It’s the force that drives the flow of electrons through a circuit and It determines the electrical potential energy that the battery can produce.  Capacity: Capacity of a battery represents the amount of electrical charge a it can store and deliver. Also it determines how long a battery can power a device. Unit of capacitance is ampere-hours (Ah) and milliampere-hours (mAh) for small battery.  Energy Density: Energy density defines the amount of energy a battery can store in per unit of volume or weight. Higher energy density means more energy in a smaller or lighter package. This characteristic indicates how quickly a battery can release its stored energy. Some batteries can provide high current output for short bursts, while others are designed for slow, continuous discharge....

Working of Battery

A battery is a electronics device that generates electric energy from chemical reaction where two electrodes involves as a main part of reaction. One is called anode(negative pole) and the other is called as cathode(positive pole)and they are separated by an electrolyte chemical component. When an external circuit is connected to the cathode and anode, electron starts to flow from the anode to the cathode and creates an electric current. Simultaneously, ions withing the electrolyte migrate between the electrodes to maintain charge balance. These electron and ion exchanges include chemical reactions at both the anode and cathode, resulting in the generation of electrical energy suitable for powering external devices. Over time, as the chemical reactants become depleted, the battery’s capacity decreases, and it needs to recharging or replacement....

Types of Battery

There are various types of batteries. Based on charging capacity we can divide them in two types:...

1. Primary Cell Battery

Primary cell batteries are designed to be used for once, and discharged. We cannot recharge this type of batteries. Some example of primary cell batteries are....

Applications of Primary Battery

Portable Electronics: Primary batteries are widely used in portable electronics devices such as portable camera, calculator, watch, remote smoke detector etc. Medical equipment: Their are such medical instruments where primary batteries are used as power source for their long term service. Hearing aids, glucose monitor, weight machine are some example those equipments. Toys: There are several toys for children and adult as well where we see the use of primary non chargeable batteries. It can provide long term service and provides power for extended play. Emergency backup: There are lot of instruments, where generally secondary batteries are used, but for safety purpose on emergency time, this type of primary non chargeable single use batteries are given more priority for backup. Space Mission: In major space mission we don’t have charging system, that’s why primary batteries are used. Also, it gives more power without charging for extended time period....

Advantages of Primary Batteries

Ready to use : Primary batteries are for useful as they don’t need to charge after buying, You directly use it. Long shelf life : As it can’t recharge itself, that’s why it made in such a way so that it can provide more shelf time as compared to others. High initial voltage : Initially the new battery provides a stable and high voltage due to its fast force chemical reaction which makes it perfect use for devices that require consistent power. Wide temperature range : This characteristics of primary battery makes them perfect for outdoor use in extrema environment. Low self-discharge : primary battery retain their energy for long time use....

Disadvantages of Primary Batteries

Non-rechargeable: Primary battery are one time use only, once it discharged, there are no use of it. For a machine, where it need to supply power for long time, we cannot use primary battery. It will make more expensive in long run. Limited capacity: As it is non rechargeable, and limited use only, so only it depleted, there is no of it. Environmental impact (waste): Once a primary battery depleted. disposal of such type of batteries can lead to pollution of our environment because of heavy metals like mercury, cadmium. Potential cost over time: We need to change the battery over time when it gets depleted. Their is no way to plate it again. So continuously it charges maintenance and a initial cost. Performance declines with use: Over time, primary battery declines it’s performance....

2.  Secondary Cell Battery

Secondary cell batteries are those types of battery which can be recharged after once it get discharged. Examples of some secondary cell batteries are :...

Application of Secondary Cell Battery

Secondary cell batteries are widely used due to it’s ability to be charged and multiple time use capacity....

Advantages of Secondary Batteries

Reusable and rechargeable: It can be used for multiple time in long term by recharging. Cost-effective in the long run: As it don’t need to change the whole battery, so it’s more cost effective. Reduced environmental impact: It less harmful for the environment as compared to primary battery also it don’t need a frequent disposal phase. Higher capacity: Secondary battery provides higher capacity as compared to primary battery. Convenient for frequent use: It can be recharged and used for multiple time frequently. Versatility: Suitable for a wide range of applications....

Disadvantages of Secondary Batteries

Require charging time: It can be charged, this type of battery. It has to wait and pause the working of machines during the charging period which are connected to the battery. Limited lifespan (finite charge cycles): Although it can be charged, it’s not for lifetime use. It also have a limited time of charging and discharging capacity. Initial purchase cost: It initially cost higher than a primary battery. Slightly lower voltage output: The output voltage of a secondary battery is lower that a primary battery....

Difference Between Primary Cell and Secondary Cell Battery

Characteristics      Primary Cell Battery           Secondary Cell Battery         Rechargeability Non-rechargeable: Single-use Rechargeable: Can be recharged multiple times Typical Chemistry Examples include zinc-carbon, alkaline, lithium, etc. Examples include lithium-ion, nickel-metal hydride (NiMH), lead-acid, etc. Voltage Fixed voltage, usually around 1.5V There is no fixed voltage. It varies by type, example : 3.6V for Li-ion, 1.2V for NiMH Capacity Lower capacity compared to rechargeable Higher capacity, suitable for high-drain devices Initial Cost Generally more affordable initial cost is high Maintenance No maintenance needed Proper charging and maintenance needed...
