Abstract: Disclosed herein is an electronic device encapsulation including a non-permeable coating and at least one pair of leads coupled to an electronic device protruding from the non-permeable coating. Also disclosed herein is a method of encapsulating an electronic device including attaching at least a pair of electric leads to the device, coating the device and a portion of each lead with a non-permeable coating, and curing the non-permeable coating. Further disclosed is an encapsulated system including a device, at least one pair of leads coupled to the device configured to extend from the device and attach to an exterior system, and a non-permeable coating configured to provide a vapor barrier surrounding the device and to provide an exposed portion of the pair of leads.

Abstract: Flexible lithium-ion batteries include patterned electrode assemblies configured to partition bending stresses when the lithium-ion battery is flexed by localizing high bending stresses. The patterned electrode assemblies can include a patterned current collector and active material or patterned active material formed on a current collector that is not patterned.
