N2 - Lithium solid electrolytes can potentially address two key limitations of the organic electrolytes used in today € s lithium-ion batteries, namely, their flammability and limited electrochemical stability. However, achieving a Li + conductivity in the solid state comparable to existing liquid electrolytes (>1 mS cm-1) is particularly ...
It is found that an underlying body-centred cubic-like anion framework, which allows direct Li hops between adjacent tetrahedral sites, is most desirable for achieving high ionic conductivity, and that this anion arrangement is present in several known fast Li-conducting materials and other fast ion conductors. Lithium solid electrolytes can potentially address two key limitations of the ...
Matching high-voltage oxide cathodes (>4 V vs. Li + /Li) with thin lithium (Li) metal (<50 µm in thickness) anodes promises Li-ion batteries with specific energies exceeding 350 watt hours (Wh) kg −1 ().However, the cycle life of thin Li-metal anodes is severely limited by short-circuits (i.e., "sudden death") caused by Li-dendrite formation and low coulombic …
