Effect of NASICON/PVdF based hybrid solid electrolyte composition on the electrode/electrolyte interface properties of Solid-State Lithium Batteries

Massive research activities have been initiated in order to solve different issues of solid state batteries, specially centred in solid electrolyte development. However, in spite of the good performance of solid electrolyte as such the interfacial contact of solid electrolyte with the electrode active materials is a serious challenge. Important parameters are based on interface impedance and electrochemical and mechanical stability with electrode materials. In order to guarantee an acceptable lifetime and cycling stability of solid batteries, stable interfaces with high contact area are required between electrolytes and active materials. Among this, the mechanical stability of the cell components and interfaces represents a serious challenge for the lifetime of solid batteries.
