In this study, we prepared a waste-induced polymeric carbon(W-PC) which has graphite-like nanodomains through a high-temperature pyrolysis process at 2,700 ℃. The W-PC has a graphitic microstructure; consisting of potato-chip like carbon layers with short range-ordered graphite domains. The unique microstructure of the W-PC led to exceptionally stable cycling performances in the harsh potassium ion storage condition with large volume expansion of > 200 %. In addition, the W-PC anode showed significantly high rate capabilities and high reversibilities for potassium ion storage. Hence, this study demonstrated that the upcycling strategy from a waste polymer to a valuable polymeric carbon can be a great alternative for future environmental and energy issues.
