Interfacial engineering for high‐performance garnet‐based solid‐state lithium batteries

“…Subsequent lithium deposition must occur at non‐planar positions, leading to Li 0 stacking, which serves as the nucleus for lithium dendrite growth (Figure 2C). 73 Therefore, the rapid migration of Li + and the sluggish diffusion of Li 0 contribute to local current density concentration and the formation of lithium dendrites 74,75 …”

Ferroelectric Nanorods as a Polymer Interface Additive for High-Performance Garnet-Based Solid-State Batteries

“…14 The calculated R ir based on the equivalent circuit shown in Figure S7 for the Li | LLZO | Li cell (blank) is 666 Ω, which is reduced to 473 Ω for the PE-modified cell and 440 Ω for the CPE-BT-modified cell. The reduced interfacial impedance benefits the critical current densities (CCDs) of the batteries, 34 as shown in Figure 4b. The Li | LLZO | Li cell was shortcircuited under a low current of 0.075 mA cm −2 , because the formed thick lithium dendrite (the regions marked by the dotted rectangle) penetrated across the LLZO pellet (Figure 4c).…”

Improvement of the Li-ion conductivity and air stability of the Ta-doped Li7La3Zr2O12 electrolyte via Ga co-doping and its application in Li–S batteries

“…29–32 The microstructure of LLZO electrolytes plays a crucial role in determining air stability and the stability of Li plating and stripping. 33,34 When the LLZO electrolyte comes into contact with CO 2 and H 2 O in the air, it reacts to form Li 2 CO 3, leading to a degradation in its performance. 30,35–37 It has been demonstrated that the initial reaction usually occurs at grain boundaries.…”
