Nokia patents foldable battery

Someday we might have a phone that folds to the size of a Post-it note and then expands to the size of a regular smartphone. For something like that to be feasible, it will have to be powered by a battery that can handle the change in sizes, and still offer enough juice to run a power hungry device.
"Even though the internal components are becoming smaller and smaller, batteries generally lag behind other technological advancements, consistently consuming a large portion of the portable electronic device.
‘In current portable electronic devices, to have a curved and aesthetically pleasing form factor, space is generally wasted between the battery and a case making the portable electronic device seem larger and a result may be less appealing,’
‘Additionally, there may also be wasted space between the internal components and the case and/or between certain internal components.’"-Nokia patent application
