  • Patent number: 12553122
    Abstract: A method of LiCoO2 film formation involves depositing a LiCoO2 layer on a substrate. This deposition is conducted by reactive magnetron sputtering of a metal cobalt (Co) target in lithium (Li) vapor onto a substrate in a vacuum chamber. A lithium tank is heated to the lithium melting point and a gas-carrier flow is fed through the heated lithium reservoir which results in the controlled feeding of lithium vapor to a magnetron system via a gas distributor. The gas distributor is connected to a working gas input and a lithium tank input. The regulated supply of lithium vapor is carried out by changing the gas-carrier flow and the lithium vapor is supplied from a heated tank.
