Advancements in the capabilities of lithium-ion batteries have slowed down in the last decade. As conventional electrode materials approach their theoretical limits, substantial gains in battery energy density only come as a trade-off in safety or performance. This talk will discuss how replacing conventional active and inactive materials will significantly improve performance, drastically reduce the cost of Li-ion batteries, and pave the way for renewable energy technologies. For example, Sila's innovative drop-in-replacement nanocomposite, silicon-based anode powder offers over five times higher gravimetric capacity than graphite, permits both fast charging and over 20% more energy density today over state-of-the-art lithium-ion, and enables radical product innovation - all without compromising performance. Most importantly, this material has been shipping in devices for nearly two years and is scaling up for massive electric vehicle (EV) use by mid-decade. With Sila’s industrialized and scaled scientific innovation, wearables, portable electronics, and EV manufacturers can create breakthrough products today that will minimize our environmental impact tomorrow. This talk will also provide multiple examples of lightweight conversion-type cathodes, flexible ceramic separators, and other technologies that may become instrumental for the transition to a clean and energy-sustainable economy.
