Oxide-based materials are most suitable from the stability point of view.
But the low conductivity of Oxide-based materials limits the application.
The details of recent lithium conducting materials are described in some review articles [14] and [15].
So it can be speculated that we can increase the density of materials by doping, and improve the total conductivity of materials.

In order to study the anti-aging properties of polypropylene / mica composite materials, the above polypropylene / mica composite materials were placed outside to study the influence of natural aging time on the anti-aging properties and to explore the natural aging mechanism of polypropylene / mica composites.
Natural aging research results show that:with the extension of the natural aging time the surface of materials will appear cracks and sheddings.
Preparation of composite materials.
