Title: Li Metal Anodes and Rechargeable Lithium Metal Batteries. Springer Series in Materials Science

Abstract

Lithium (Li) metal is an ideal anode material for rechargeable batteries. With the urgent need for the “next generation” rechargeable batteries, such as Li-S, Li-air batteries as well as rechargeable Li metal batteries using Li intercalation compounds as the cathode, the use of Li metal anode has attracted significant interests in recent years. Unfortunately, rechargeable batteries based on Li metal anode have not yet been commercialized mainly due to two barriers: one is the growth of Li dendrites and associated safety hazard, and another is the low Coulombic efficiency (CE) of Li cycling and associated early battery failure due to Li powdering and increasing cell impedance. To have a high CE, minimum side reactions between freshly/native deposited Li and electrolyte has to be minimized. These reactions are proportional to the chemical and electrochemical activity of native Li when they are in direct contact with surrounding electrolyte. They are also proportional to the surface area of deposited Li. This means that high CE of Li deposition/stripping always related to a low surface area Li deposition and suppressed Li dendrite growth. Therefore, the enhancement of CE is a more fundamental factors controlling long term, stable cycling of Li metal anode. In thismore » book, we will first review the general models of the dendrite growth mechanism. The effect of SEI layer on the modeling of Li dendrite growth will also be discussed. Then we will discuss various instruments/tools that are critical for the investigation of Li dendrite growth. In the Chapter 3, various factors which affect CE of Li cycling and dendrite growth will be discussed together with an emphasize on enhancement of CE. Chapter 4 of the book will discuss the specific application of Li metal anode in several key rechargeable Li metal batteries, including Li-air batteries, Li-S batteries and Li metal batteries using intercalation compounds as cathode. At last, the perspective on the future development and application of Li metal batteries will be discussed in the Chapter 5.« less
