Advancements in separator design for supercapacitor technology: A . . . The separator prevents mechanical harm and excessive temperatures in the device, ensuring safety For superior-performance SCs, the separator must be porous, compact, highly permeable, mechanically robust, hydrophilic (low contact angle), non-combustible, and have high ionic conductivity [43]
A roadmap of battery separator development: Past and future The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active
