Inordertosuccessivelycompetewithsupercapacitors,anabilityoffastdischargeisamustforlithium-ionbatteries.Fromthispointofview,stoichiometricandsubstitutedlithiummanganesespinelsascathodematerialsareoneofthemostprospectivecandidates,especiallyintheirnanosizedform.Inthisarticle,anoverviewofthemostrecentdataregardingphysico-chemicalandelectrochemicalpropertiesoflithiummanganesespinels,especially,LiMn2O4andLiNi0.5Mn1.5O4,synthesizedbymeansofvariousmethodsispresented,withspecialemphasisoftheiruseinhigh-rateelectrochemicalapplications.Inparticular,specificcapacitiesandratecapabilitiesofspinelmaterialsareanalyzed.Itissuggestedthatreducedspecificcapacityisdeterminedprimarilybytheaggregationofmaterialparticles,whereasgoodhigh-ratecapabilityisgovernednotonlybythesizeofcrystallitesbutalsobytheperfectnessofcrystals.Themosttechnologicallyadvantageoussolutionsaredescribed,existinggapsintheknowledgeofspinelmaterialsareoutlined,andthewaysoftheirfillingaresuggested,inahopetobehelpfulinkeepinglithiumbatteriesafloatinthestruggleforaworthyplaceamongelectrochemicalenergysystemsofthe21stcentury.
