Abstract

original image

Auf ein langes Leben: Ein LiFePO4-Kohlenstoff-Komposit, bestehend aus einem hochkristallinen, 20–40 nm großen LiFePO4-Kern und einer 1–2 nm dicken Semigraphit-Schale, ergibt hohe Batterieleistungen bei sehr langer Zykluslebensdauer (siehe Diagramm). Die verwendete Synthesemethode kann auf die Herstellung anderer Materialien wie Li4Ti5O12-Kohlenstoff- und Mn3O4-Kohlenstoff-Komposite übertragen werden.
