| Abstract: | The practical realization of all-solid-state lithiummetal batteries depends on the development of low interfacial resistance between the solid electrolyte and electrodes. Herein, an organic-inorganic hybrid solid electrolyte, formed by an organic network of poly(ethylene oxide) chains that is connected with an inorganic Si-O-Si backbone network containing lithium salt, is proposed as a new interfacial material between a garnet-type oxide solid electrolyte and high-potential cathodes. The properties of the hybrid solid electrolyte are evaluated to obtain a material that is chemically and electrochemically compatible with the solid electrolyte and active material. Thereafter, the different procedures to fabricate a low-resistance solid-solid interface between the solid electrolyte and LiCoO2 using the hybrid solid electrolyte are evaluated. The hybrid solid electrolyte provides an ionic/electronic percolation of active material particles and excellent adherence properties, thereby enabling the operation of the all-solid-state battery at room temperature to achieve a high initial discharge capacity of 125 mAh.g(-1). |
