Title:StudyontheSynthesisandPotassiumStoragePerformanceofBoron-DopedPorousCarbon
Abstract:
Inrecentyears,thedevelopmentofcarbon-basedmaterialsforenergystorageandconversionhasgainedsignificantattention.Thisstudyfocusesonthesynthesisandpotassiumstorageperformanceofboron-dopedporouscarbonmaterials.Theaimistoexplorethepotentialapplicationofthesematerialsinpotassium-ionbatteries.Thesynthesismethod,structuralcharacterization,andelectrochemicalperformanceoftheboron-dopedporouscarbonmaterialsareinvestigated.Theresultsshowthattheborondopingeffectivelyenhancesthepotassiumstorageperformanceofthecarbonmaterials,makingthemapromisingcandidateforadvancedenergystorageapplications.
1.Introduction:
Potassium-ionbatterieshaveattractedmuchattentionasafuturealternativetolithium-ionbatteriesduetotheabundantresourceofpotassiumandthecomparableelectrochemicalcharacteristics.However,thedevelopmentofsuitableelectrodematerialsforpotassium-ionbatteriesremainsachallenge.Carbon-basedmaterialsareconsidereddesirablecandidatesduetotheirhighelectricalconductivity,goodchemicalstability,andabundantporosity.Inthisstudy,wefocusonboron-dopedporouscarbonmaterialsaspotentialcandidatesforpotassium-ionbatteryapplications.
