Here is an interesting primer on Li Ion battery chemistry and material developments By Dr Shirley Meng from back in 2017.
Dr. Shirley Meng received her Ph.D. in Advance Materials for Micro & Nano Systems from the Singapore-MIT Alliance in 2005, after which she worked as a postdoc research fellow and became a research scientist at MIT. Shirley is currently the Associate Professor of NanoEngineering and Materials Science, University of California San Diego (UCSD) and the founding Director of Sustainable Power and Energy Center (spec.ucsd.edu ).

Her research group – Laboratory for Energy Storage and Conversion (LESC) – focuses on functional nano and micro-scale materials for energy storage and conversion. The more recent programs include the design, synthesis, processing, and operando characterization of energy storage materials in advanced rechargeable batteries; new intercalation materials for sodium ion batteries; and advanced flow batteries for grids large scale storage.
