A Simple One-Dimensional Transport Model to Explain Inverse Signatures in Lithium-Metal Batteries

摘要

Lithium metal is being investigated as the negative electrode for lithium batteries due to its high theoretical capacity (3,860 mAh g~(-1)) and negative electrochemical potential (-3.040 V vs standard hydrogen electrode). However, using lithium metal poses several challenges, including dendritic electrodeposition and accumulation of dead lithium. These phenomena can cause the cell to short, and also contribute to poor cyclability.
