| Summary: | The formation of lithium dendrites can lead to irreversible capacity loss and pose safety risks in lithium batteries. One proposed model suggests that when the current density is too high, a depletion layer of lithium ions forms near the anode, promoting dendrite growth. Lithium dendrites may puncture the membrane of the battery and reach the positive electrode, causing the battery to short circuit, causing the battery to overheat and possibly explode. This growth can result in short circuits in conventional lithium batteries. Several strategies can be employed to inhibit the growth of lithium dendrites. These include coating the lithium metal surface with durable layers or alloy compounds, micro-modulating the solid-state electrolyte to reduce dendrite nucleation, and managing nano-cracks in the electrolyte. These approaches have shown promising results in enhancing the stability and cycling performance of lithium metal anodes. However, technological constraints still limit the widespread implementation of these strategies, and more advanced characterization techniques are needed to better understand and address the issue of dendrite growth in solid-state batteries. |
