Abstract Nowadays, addressing the drawbacks of liquid electrolyte-based batteries is a hot and challenging issue, which supposed to be fulfilled through solid electrolyte systems such as polymer electrolytes. Polymer blend electrolytes (PBEs) are widely investigated viable options solve undesired characteristics their counterparts also poor ionic conductivity homopolymer-based Even though PBEs outperform in terms performance, pristine quite low for practical applications (i.e. below 10 –3 S/cm at room temperature). A very promising approach this limitation incorporate additives into systems, select suitable polymeric materials employ desired synthesizing techniques performance strongly dependent on selection inherent properties polymers), nature amount salts other additives, employed synthesize hosts and/or electrolytes, determining functionality, amorphousness, dielectric constant, dimensional stability, and, ultimately, electrochemical performances system. This paper reviews different factors affecting miscibility blends, techniques, thermal, chemical, mechanical PBEs, challenges opportunities PBEs. Moreover, presents current progress well future prospects advancing energy storage sectors.
