The typical Li-ion battery will be composed of a graphite anode, an organic liquid-based electrolyte, and a cathode choice of lithium cobalt oxide, nickel-cobalt-manganese/aluminum oxide (NMC/NCA) or lithium iron phosphate (LFP). Advanced Li-ion refers to silicon and Li-metal anodes, alternative and solid-electrolytes, high-Ni and high-voltage cathodes and other cell design factors. Driven by the burgeoning opportunity for supplying the electric vehicle market, companies are striving to develop, understand, and commercialize new technologies to maintain and grow their share of the battery market.
For example, silicon and Li-metal anodes can offer significant improvements to energy density, but they serve as a reminder of the trade-offs often required in improving one area of battery performance, with cycle life and manufacturability being challenges to adoption. As a result, developers and manufacturers are keen to learn about and design new chemistries on a mass scale to be implemented effectively into EVs.
