180 Wh kg −1 and 497 Wh L −1) at the power densities of 200 W kg −1 and 600 W L −1, corresponding to ca. This assessment allowed us to identify values of the LLZO thickness, cathode areal capacity, and LLZO content in the solid-state cathode required to match the energy density of conventional lithium-ion batteries (ca. In this work, we analyzed the energy densities of Li-garnet all-solid-state batteries based solely on LLZO SSE by modeling their Ragone plots using LiCoO 2 as the model cathode material.
10 mS cm −1 at RT) still raise the question as to the feasibility of using solely LLZO as an electrolyte for achieving competitive energy and power densities. However, high LLZO density (5.1 g cm −3) and its lower level of Li-ion conductivity (up to 1 mS cm −1 at RT) compared to liquid electrolytes (1.28 g cm −3 ca. 10 −8 S cm −1 (RT) and a wide electrochemical operation window of 0–6 V vs. Among the plethora of solid-state electrolytes (SSEs) investigated, garnet-type Li-ion electrolytes based on cubic Li 7La 3Zr 2O 12 (LLZO) are considered the most appealing candidates for the development of future solid-state batteries because of their low electronic conductivity of ca.
Replacement of Li-ion liquid-state electrolytes by solid-state counterparts in a Li-ion battery (LIB) is a major research objective as well as an urgent priority for the industry, as it enables the use of a Li metal anode and provides new opportunities to realize safe, non-flammable, and temperature-resilient batteries.
