Spatial Assessment of Soil Organic Carbon Using Bayesian Maximum Entropy and Partial Least Square Regression Model

Abstract

This paper proposes a strategy to stabilize the garnet/Li interface by introducing Li3PO4as an additive in garnet-type Li6.5La3Zr1.5Ta0.5O12. The Li3PO4-added Li6.5La3Zr1.5Ta0.5O12electrolyte exhibits a room-temperature Li-ion conductivity of 1.4ï¿½× 10−4�S�cm−1, which is less than that of the Li3PO4-free counterparts (4.6ï¿½× 10−4�S�cm−1). However, the presence of Li3PO4improves the interfacial compatibility and suppresses Li-dendrite formation during Li-metal plating/stripping. The symmetric Li/garnet/Li cells with Li3PO4-added Li6.5La3Zr1.5Ta0.5O12have been successfully cycled at a current density of 0.1�mA�cm−2at 60��C for 60�h; on contrast, the control cells with Li3PO4-free Li6.5La3Zr1.5Ta0.5O12display noisy potential with large voltage polarization and get short-circuited completely after 33-h cycling under the same operating condition. The outstanding interface stability can be attributed to the in situ reaction of the Li flux with Li3PO4to form a self-limiting and ion-conducting interphase, Li3P, which is confirmed experimentally.
