Abstract

Dual lithium-containing hydride/oxide shells are constructed by in situ mechano-induced assembly of Li₃PO₄ reacting with LiBH₄. The ionic conductivity of the Li₃PO₄-based composite is promoted nearly 4 orders of magnitude, up to 0.04 mS cm⁻² at 75 °C as compared to the pure one, possessing an electrochemical window of −0.2–5 V (vs. Li/Li⁺).
