Lithium (Li)-ion batteries have become the pivot of modern energy storage due to their predominant role in powering consumer electronics and electric vehicles. However, with mature manufacturing and production, the energy density of current Li-ion batteries is reaching the theoretical limit.Substantial efforts in both academia and industry are being made to invent next-generation battery chemistries, such as near-future trending Li-ion electrodes including silicon (Si) based anodes, high-voltage LiNi0.5Mn1.5O4 (LNMO) cathode, layered Li-rich Mn-based oxide (LLMO) cathodes, etc. and far-future high-energy Li metal batteries.For near-future Li-ion chemistries such as Si based anodes, LNMO and LLMO cathodes, the existing electrolyte technologies are far from satisfaction. Therefore, liquid electrolyte engineering becomes a pragmatic and imperative approach, and calls for rational design and in-depth understanding of new electrolytes.Li metal battery is a technology existed and commercialized before Li-ion counterpart but forsaken due to safety issues. The kernel, Li metal anodes, endows batteries with high specific energy; however, this is accomplished at the expense of reduced cycle life and increased safety hazards due to the extremely high reactivity and volume fluctuation of Li metal anodes. Therefore, continuous developments of Li metal batteries are demanded to meet the requirements of practical applications.In Chapter 1, background will be provided on current status and recent research efforts of next-generation Li-ion and Li metal batteries. In Chapter 2 and 3, material design artificial solid-electrolyte interphase for protecting Li metal anodes will be discussed. In Chapters 4 and 5, liquid electrolyte engineering and iterative tuning of molecular structure will be elaborated. In Chapter 6, fine tuning of carbonate electrolytes will be demonstrated in the trending Li-ion batteries for near-future practical applications. In Chapter 7, summary and promising directions of future battery developments will be outlooked.
