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. |
