The term “lithium dendrite” refers to the branch-like metallic lithium formed during the reduction of lithium ions in the charging and discharging process of lithium batteries.
The formation and growth models of dendrites in liquid lithium-ion batteries have been extensively studied . To date, there are four relatively mature models, namely the space-charge model , the heterogeneous nucleation model , the deposition and dissolution model , and the stress-driven model .
During battery operation, these micro-defects generate stronger electric and ionic fields than the smooth surface, inducing the deposition of lithium ions at these sites. This leads to the formation of initial dendrites. The research on the origin of dendrites in SEs can be based on the experiments conducted by Geoff McConohy's experiment .
Paridhi Garg, in Journal of Energy Storage, 2022 A sporadic electro-deposition of lithium on the electrode causes protrusions, known as lithium dendrites which hinder the battery lifetime and its safety. The lithium ions are found in both liquid and polymer-based electrolytes due to the presence/addition of suitable salts.
The analysis results showed that lithium dendrites grow through interconnected openings, and the surface-modified layers of Li 2 CO 3 and LiOH could fill the voids and contribute to sinter to improve the CCD. They suggested that improving the interconnection between grains and reducing voids was a help to inhibit the formation of lithium dendrites.
