CHAPTER 1. New High-energy Anode Materials

Abstract

New anode materials that can deliver higher specific capacities compared to the traditional graphite in lithium-ion batteries (LIBs) are attracting more attention. In this chapter, we discuss the current research progress on high-energy-density anode materials including various carbons, MXenes, silicon, metals, metal oxides, metal sulfides and lithium metal. Electrochemical reaction mechanisms such as electrode volume change, solid-electrolyte interphase formation, and the corresponding solutions are discussed respectively. In particular the Li metal in rechargeable Li–metal batteries, Li–air/oxygen batteries and Li–sulfur batteries is described.
