Energetics of ionic transport on Li$_w$Si$_x$P$_{1-x}$O$_y$N$_z$ amorphous and glassy electrolytes

Résumé

Lithium phosphorous oxynitride (LIPON), having an amorphous structure, was first synthesized at the Oak Ridge National Laboratory in the 1990s. Its development has arisen from the pursuit of solid electrolytes stable against lithium metal (Li) to fabricate micro-batteries employing by radio-frequency (RF) magnetron sputtering. Strictly speaking, LiPON is not thermodynamically stable against Li. However, a passivating solid electrolyte interphase emerging between Li and LiPON comprises decomposition products (Li3N and Li2O) thermodynamically stable against Li. Along with the suitable electrochemical stability, the low electronic (<10$^{-10}$ Ω$^{-1}$.cm$^{-1}$) and moderate ionic (>10$^{-6}$ Ω$^{-1}$.cm$^{-1}$) conductivity have been also refereed as key properties for its applications as thin-film electrolytes.
