Studies on the target conditioning for deposition of LiCoO2 films

Write-Once-Read-Many-Times Memory Characteristics with a Large Memory Window Operating at a Low Voltage by Li-Ion Incorporation from the LiCoOx Ion-Supplying Layer into the InGaZnO Channel of a Thin-Film Transistor

“…Figure b shows the O 1s spectra in the LiCoO x ion-supplying layer of nonprogrammed and programmed devices. The peak at 529 eV is for lattice oxygen, while the higher binding energy peak at 531 eV could be assigned as the Li 2 O peak , or nonlattice oxygen peak. , Assuming that the peak around at 531 eV is assigned to the oxygen peak of Li 2 O, the reduced relative intensity of Li 2 O after programming is interpreted with the Li + ion escape from the LiCoO x layer, which is also consistent with the TOF-SIMS and electrical results. Also, if the peak is assigned to nonlattice oxygen, the escape of Li + ions from the LiCoO x layer would also lead to the increase of relative intensity of the lattice oxygen peak as shown in Figure b because the depletion of Li + ions increases the relative ratio of oxygen anions to metal cations.…”

Synthesis and electrochemical properties of Ti doped LiCoO2 thin film cathodes

“…In the fabrication of LiCoO 2 thin films formation of the 2-D structure is known to be crucial for obtaining a good mobility of the lithium ions. Various aspects of LiCoO 2 thin films prepared by RF sputtering [6][7][8][9][10], pulsed laser deposition [11][12][13][14][15], electrostatic spray [16], and chemical vapour deposition [17], have been reported. PLD has been widely recognized as a very promising, versatile and efficient method for the deposition of metal oxide thin films [18].…”

Nanocrystalline LiMn2O4 thin film cathode material prepared by polymer spray pyrolysis method for Li-ion battery

“…The battery property depends upon three important factors such as nature of cathode, anode and the types of electrolyte used. Various kinds of lithium transition metal oxides have been used as cathode materials for rechargeable lithium batteries [1][2][3][4]. Among them, lithium manganese oxide (LiMn 2 O 4 ) based materials are of considerable interest as a cathode material because of its less toxicity, low cost, high operating voltage [5,6], etc.…”
