Lithium-ion (Li-ion) batteries are a type of rechargeable battery that have become ubiquitous in modern electronics due to their high energy density, low self-discharge rate, and long lifespan. These batteries are composed of lithium ions that move from the negative electrode to the positive electrode during discharge, and back when charging. They are used in a wide range of devices, from small electronics like smartphones and laptops to large applications such as electric vehicles and grid storage systems. Li-ion batteries are favored for their efficiency and performance, but they also pose challenges such as safety risks related to overheating and potential environmental impacts during disposal. Ongoing research aims to improve their safety, capacity, and sustainability, making them a crucial component of modern technology.
