ABSTRACT
Rapid development of mobile electric devices, ranging from microscale sensors to buses and boats, stimulates the search for efficient, safe, and compact energy sources. While most of the production costs of lithium batteries are generated by cathode and anode materials, the proper selection of electrolyte often becomes the key factor that determines the safety and longevity of the device. Initially, the polymer electrolytes, usually prepared by the solvent-cast method, comprised only high-molecular-weight polymers and low amounts of lithium salts. The addition of a small amount of inorganic filler is known to improve the ionic conductivity of polymer electrolytes, which is usually attributed to the interaction of the surface groups of such fillers with charge carriers. The positive influence of inorganic fillers on the ionic conductivity of polymer electrolytes is generally attributed to several factors. In polymer electrolytes, such a model may refer directly to the transport of anions.
