Lithium-Ion Battery Systems and Technology

Abstract

During the last 15 years, lithium-ion batteries have dominated the advanced energy sources by powering the modern portable electronics and replaced many other commercial battery systems in the market. The prime reasons for its rapid success and proliferation in consumer electronic market are its superior characteristics over other battery systems, namely, high voltage, high-energy density, and longer cycle and shelf life with no memory effect. The significant progress of Li-ion batteries is mainly due to numerous innovations and advancements in materials, designs, and safety. This entry is intended to provide an overview of Li-ion batteries on several aspects. Starting with a brief discussion on its history, commercial success, and working mechanism, all the critical components inside the cell have been discussed in adequate detail. The later part of this chapter will primarily focus on manufacturing process, recent advances, and modern trends in Li-ion systems and detailed discussion on Li-ion cell safety.
