ABSTRACT: Lithium-ion batteries (LIBs) have revolutionized the world of portable electronics and enabled a viable electrified vehicle market to unfold. This is all attributed to LIBs’ high energy density, long cycle life, and acceptable cost. Unfortunately, people always demand more – chief among them is higher energy density (or run-time). This constant demand for more energy in smaller volumes requires the need for high energy density positive electrodes (cathodes) and negative electrodes (anodes), while still maintaining consumer safety. In this presentation, I will give a brief background of LIBs and will discuss the applied R&D efforts in advanced active materials, electrolytes, and separators. This includes silicon-based anodes and high-nickel cathodes, and many of the design and production techniques that must be obeyed to guarantee long life and safety.
