Li-ion batteries are now penetrating the automotive market, and this will increase at a rate largely dependent on liquid fuel prices and the cost of automotive Li-ion battery systems. As a first step in determining what is “beyond Li-ion”, we will project cell weight, volume, and cost reductions achievable through successful implementation of advanced Li-ion materials. We will then consider the potential for Li-air and Li-S chemistries to enable automotive systems that surpass advanced Li-ion-based systems.
