Electrode　stability　has　been　an　important　parameter　in　energy　conversion　and　storage　devices.　However,　many　of　these　electrodes　suffer　from　irreversible　degradation,　for　example,　irreversible　sulfation　in　the　negative　electrode　of　lead　acid　battery　(LAB)　and　lithium　dendrite　on　the　anode　surface　of　lithium　ion　battery　(LIB).　We　here　report　a　facile　synthesis　approach　of　graphitized　mesoporous　carbons　(GMCs),　which　derived　from　zeolitic　imidazolate　frameworks-8　(ZIF-8)　via　controlling　the　annealing　parameters,　as　porous　media　in　the　electrodes　for　suppressing　the　irreversible　sulfation　and　the　dendritic　lithium　formation.　GMC　additive　in　the　negative　electrode　of　LAB　effectively　retards　the　irreversible　sulfation　by　controlling　the　growing　size　of　PbSO4　crystal　particles.　The　cycle　life　of　LAB　extends　8.5　times　after　being　added　GMC　additive.　Dendrite　growth　in　LIBs　is　suppressed　obviously　because　GMCs　control　the　lithium　growth　along　the　mesoporous　structure　and　the　particle　voids　of　GMCs,　resulting　in　the　significant　extension　of　operation　time　of　the　LIB　without　a　short　circuit.　The　capacity　retention　of　Li　and　Li/GMC　anodes　are　42.3%　and　90.1%,　respectively,　at　0.5　C　after　200　cycles.　The　work　reveals　a　facile　but　efficient　synthesis　approach　of　additive　to　extend　the　cycle　life　of　LABs　and　LIBs.　(C)　2018　The　Electrochemical　Society.
