Historically, the fields of materials science, chemical engineering, and chemistry work in concert to develop electrodes that have higher Li ion capacities and electrolytes that provide sufficient transport of Li ions while minimizing unintended side reactions that cause degradation. It follows that increasing battery performance involves approaches to improve the performance of these three components. A typical battery consists of three components: an anode (negatively charged electrode), cathode, (positively charged electrode), and an electrolyte that provides the transport of Li ions. Moreover, as the rate of EV adoption increases, there is further motivation and urgency to augment the electrical grid capacity, which also benefits from improved batteries though not necessary the same batteries used in EVs. It is generally accepted that achieving the widespread adoption of EVs requires batteries with higher energy density and lower cost, use sustainable materials, and exhibit improved safety compared to state-of-the-art (SOA) Li-ion technology. Currently, however, owing to depleting fossil fuels and impacts on the climate, there is an urgent need to electrify transportation. Internal combustion engines revolutionized transportation and advanced civilization in ways that were unimaginable at the turn of the twentieth century.
