Fabrication of patterned LiCoO₂ films deposited on the membrane surface of a paper-like substrate

In-situ shaped, sized, reacted, and oriented LiCoO₂ positive electrode materials were fabricated on a flexible substrate such as the paper-type Teflon membrane at low-temperature using soft solution processing without firing/sintering or melting. Supersaturation and nucleation transfer were applied to membranes placed at the supersaturation position near the Co working electrode, forming the direct attachment of a positive electrode separator for lithium batteries.
