What is Battery?
A battery is an electrochemical device that stores and releases energy through chemical reactions. It typically consists of electrodes, an electrolyte, and a separator, facilitating the flow of electrons. Chemical cells or batteries, are essential power sources for countless applications, providing portable and reliable electrical energy for devices ranging from cell phones and laptops to electric vehicles and grid-scale energy storage systems. Common types of batteries that we see around us are lithium-ion batteries, lead-acid batteries, nickel cadmium batteries, etc.
Properties of Battery
Batteries come in various shapes, sizes, and chemistries, each with its own set of properties tailored to specific applications. Some key properties of batteries include:
- Higher energy density means more power in less space or weight, crucial for portable electronics and EVs.
- Voltage indicates the potential difference between a battery’s terminals, crucial for device compatibility.
- The number of charge-discharge cycles a battery can endure before capacity drops significantly.
- Ensuring batteries are safe from malfunction or failure, crucial for human health and environmental protection.
- The financial factor determining battery viability, influenced by manufacturing, scale, and technology advancements.
Applications of Chemistry in Battery
A chemical cell, or a battery, is a device that converts chemical energy into electrical energy through electrochemical reactions. Some of the examples of these batteries are alkaline batteries, lithium ion batteries, lead acid batteries, etc. The functioning of these batteries are based on various chemical reactions. In this article, we will discuss the application of chemistry in batteries, i.e., how chemistry is involved in the functioning of these batteries.
