Learn All about Battery and its Types.
Batteries have become an integral part of our daily lives, powering various electronic devices such as watches, computers, electric vehicles, and satellites. The diverse applications of batteries require different sizes and types to meet specific needs. In this discussion, we will focus on the common types of batteries used in everyday life.
What is inside a Battery?
At its core, a battery is a collection of cells undergoing chemical reactions to generate an electron flow in a circuit. The development of battery technology has seen continuous advancements, leading to breakthroughs in various applications worldwide. Batteries play a crucial role in storing generated electrical energy, allowing for portability and powering standalone devices.
The basic components of a battery cell include the anode (negative electrode), cathode (positive electrode), and electrolytes. By altering the materials and arrangement of these components, different battery chemistries and types can be achieved.
There are two main types of batteries: Primary Batteries and Secondary Batteries.
Primary Batteries:
Primary batteries are non-rechargeable and consist of electrochemical cells with irreversible chemical reactions. They find applications in military devices, remote controls, and other scenarios where recharging is impractical. Examples include alkaline, zinc-carbon, lithium, mercury, silver-oxide, zinc-air, and zinc-chloride batteries. These are suitable for low-power devices and have high specific energy but limited load current.
Secondary Batteries:
Secondary batteries, also known as rechargeable batteries, can be recharged after depletion. They are utilized in high-drain devices, electric vehicles, and standby power systems. Examples include Nickel-Cadmium (Ni-Cd), Nickel-Metal Hydride (Ni-MH), Lead-Acid, Lithium-ion (Li-ion), Lithium Iron Phosphate (LiFePO4), and others. These batteries vary in chemistry, affecting attributes such as energy density, cycle life, and shelf life.
Rechargeable Batteries:
Nickel-Cadmium (Ni-Cd): Good life cycle, susceptible to memory effect, used in portable devices and electric vehicles.
Nickel-Metal Hydride (Ni-MH): High capacity, energy density, and cycle durability, immune to memory effect.
Lead-Acid: Low-cost, reliable, used in heavy-duty applications like solar-panel energy storage and vehicle ignition.
Lithium-ion (Li-ion): Commonly used, high energy density, little memory effect, used in portable electronics, electric vehicles, and aerospace applications.
Choosing the right battery involves considering factors like energy density, power density, safety, life cycle durability, and cost. The selection significantly impacts the success of projects requiring extended battery life, such as those on the Internet of Things (IoT). Different battery sizes, ranging from coin cells to AA batteries, cater to various electronic devices. When selecting a battery for a project, factors like energy density, power density, safety, life cycle durability, and cost play essential roles. Each battery type has its strengths and limitations, and choosing the right one is crucial for the success of the application.
