The application’s illustrative figures demonstrate how the proposed design method can produce batteries that are circular, triangular, or even “L”-shaped. The technology could even produce batteries with rounded edges, so that future devices with rounded bezels can maximize battery capacity by having the battery run flush with the outer edge of the case.

The application further notes how the new batteries may be designed with hollow interiors, allowing for additional electronic components to be packaged inside the battery itself. All of these developments, if realized, will provide Apple with the tools to both reduce device thickness while at the same time increase battery life.
