Quick Overview

A lithium-ion battery, often abbreviated as Li-ion battery, is a rechargeable energy storage device known for its high energy density, long cycle life, and lightweight design. These batteries are widely used in portable electronics, electric vehicles, renewable energy systems, and more.

How It Works

A lithium-ion battery, often referred to as Li-ion battery, is a rechargeable energy storage device that harnesses the electrochemical properties of lithium ions to store and release electrical energy. Inside a Li-ion battery, there are positive and negative electrodes typically made of lithium cobalt oxide (LiCoO2) and graphite, respectively. Separating them is an electrolyte, which allows lithium ions to move between the electrodes during charging and discharging. When the battery is charged, lithium ions are driven from the positive electrode (cathode) to the negative electrode (anode), storing energy. During discharge, these ions flow back to the cathode, generating electrical power. Li-ion batteries are prevalent in portable electronics, electric vehicles, and renewable energy systems due to their high energy density, rechargeability, and longevity.
