Room-temperature synthesis of crystallized LiCoO2 thin films by electrochemical technique

Direct fabrication of LiCoO2 thin-films in water–ethanol solutions by electrochemical–hydrothermal method

“…Many recent works studied new routes for the deposition of thin film batteries components including screen printing, doctorblade/spin coating and electrodeposition [4][5][6][7][8][9]. Many groups have investigated hydrothermal methods to prepare LiCoO 2 [10][11][12][13][14]. The electrochemical-hydrothermal technique, combining the generation of oxidized species at the surface of the substrate and chemical reactions occurring under hydrothermal conditions was found particularly to be an easy way to fabricate LiCoO 2 thin films and is only reported in few studies [15][16][17].…”

Electrodeposition of Li-Ion Cathode Materials: The Fascinating Alternative for Li-Ion Micro-Batteries Fabrication

“…Lai et al 114 described the ECD of LCO at room temperature on a Co substrate. They also investigated the influence of different experimental conditions on the crystalline structure and morphology of the electrodeposited LCO films.…”

Electroplating lithium transition metal oxides

“…ALD is also not appropriate for thick films because of the very slow deposition rate. Before this report, electrodeposition, although successful for the syntheses of some oxide ceramics (12,13), had not been demonstrated for the growth of high-quality LTMOs (14)(15)(16)(17)(18)(19)(20). Previously electroplated LTMOs exhibited poor electrochemical performance because of the inclusion of water, undesired cations, transition metals at incorrect valance states, and disorder in the crystal structure (21,22).…”
