A battery is an energy storage device that converts chemical energy into electrical energy. It is used in various areas of our daily life, such as mobile phones, laptops, torches, cars, etc. The main function of a battery is to provide the necessary electricity to keep electrical appliances running. Batteries can be of different types — rechargeable (rechargeable) and non-rechargeable (disposable after one use). In today's modern era, lithium-ion batteries are the most popular because they are lightweight, have high capacity, and last longer.
By using batteries, we can easily run portable devices that make our work more efficient. The basic principle of a battery is that a chemical reaction occurs inside it that produces electrons; this electron flow is used as electrical energy. The better the quality and the larger the capacity of the battery, the longer it can provide power. Proper use and regular maintenance help to increase the life of the battery. Therefore, batteries are one of the integral parts of our modern technology.
