Abstract
The invention is directed to a flexible and stretchable battery which is formed of an assembly having anode side and a cathode side separated by a separator and sealed in a packaging. The assembly is in a folded configuration and contains at least one cut therein, such that when the assembly is unfolded and subjected to subsequent deformation, a final folded state of the battery is able to stretch beyond a flat planar state of the battery in all dimensions.

A flexible and stretchable battery comprising an assembly having an anode side and a cathode side separated by a separator and sealed in a packaging, wherein the assembly is in a folded configuration and contains at least one cut therein, such that when the assembly is unfolded and subjected to subsequent deformation, a final folded state of the battery is able to stretch beyond a flat planar state of the battery in all dimensions.
A method of making a flexible and stretchable battery, comprising the steps of:
- forming an assembly having an anode side and a cathode side separated by a separator and sealed in a packaging;
- folding the assembly;
- and
- cutting the assembly, such that when the assembly is unfolded and subjected to subsequent deformation, a final folded state of the battery is able to stretch beyond a flat planar state of the battery in all dimensions.
An electronic device comprising:
- electronics;
- and
- at least one flexible and stretchable battery that provides power to the electronics, the at least one flexible and stretchable battery comprising an assembly having an anode side and a cathode side separated by a separator and sealed in a packaging, wherein the assembly is in a folded configuration and contains at least one cut therein, such that when the assembly is unfolded and subjected to subsequent deformation, a final folded state of the battery is able to stretch beyond a flat planar state of the battery in all dimensions.
