Lithium-ion batteries are popular because they have a number of important advantages over competing technologies: They're generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Bureau of Indian Standards (BIS) has strictly laid standards for lithium-ion batteries. If a company wants to import Li-ion batteries for Electric Vehicles in India, they must abide by the norms and certify to the BIS standards.
