Abstract

Lithium nickel oxide thin-film electrodes for lithium rechargeable microbatteries are directly fabricated from nickel substrates using the electrochemical-hydrothermal method in 4 M LiOH solution in the temperature range between 100 and 200 °C and a current density between 0.1 and 5.0 mA/cm2 for 20 h. The film properties show the obtained lithium nickel oxide films to be possible cathode films. However, the properties depend on the film formation conditions. Investigation of the effects of the film fabrication conditions gives fundamental information on film formation pathways and optimum conditions for lithium nickel oxide film formation. The successful separation of two different intermediate stages and the subsequent obtaining of lithium nickel oxide films confirms the film formation mechanism.
