1. A cathode made by a process of:
- depositing a film of LiCoO2 on a substrate;
rapidly heating the film of LiCoO2 to a target temperature; and
maintaining the film of LiCoO2 at the target temperature for a target annealing time of at most approximately 60 minutes, wherein a majority of grains in the film of LiCoO2 are oriented with their (101) and (104) planes parallel to the substrate.

Abstract
Systems and methods are described for fabrication of highly textured lithium cobalt oxide films by rapid thermal annealing. A method of forming a lithium cobalt oxide film includes depositing a film of lithium cobalt oxide on a substrate; rapidly heating the film of lithium cobalt oxide to a target temperature; and maintaining the film of lithium cobalt oxide at the target temperature for a target annealing time of at most, approximately 60 minutes. The systems and methods provide advantages because they require less time to implement and are, therefore less costly than previous techniques.
