Hidden Negative Issues and Possible Solutions for Advancing the Development of High-Energy-Density in Lithium Batteries: A Review.

Abstract

This review article discusses the hidden or often overlooked negative issues of large-capacity cathodes, high-voltage systems, concentrated electrolytes, and reversible lithium metal electrodes in high-energy-density lithium batteries and provides some feasible solutions that can realize the construction of realistic rechargeable batteries with higher energy densities. Similar objective discussion of the negative aspects of lithium-air batteries, multi-valent shuttles, anion shuttles, sulfur cathode systems, and all-solid ceramic batteries can help fabricate more realistic batteries.
