Abstract

Sowing the seeds of dissolution. Trace amounts of copper fluoride allow direct dissolution of lithium nitrate in an ethylene carbonate/diethyl carbonate electrolyte mixture. In their Communication (DOI: 10.1002/anie.201807034), Q. Zhang et al. bypass the low solubility of lithium nitrate—a common protective additive in ether electrolytes used in lithium metal batteries. A working high‐voltage lithium metal battery retained high capacity and Coulombic efficiency after 300 cycles.
