1. A flexible battery assembly comprising:
a flexible battery comprising:
an anode having a first anode side and a second anode side,
a cathode having a first cathode side and a second cathode side, wherein the first cathode side faces the first anode side,
a first flexible separator membrane proximal to the second anode side,
a second flexible separator membrane proximal to the second cathode side, and
a third flexible separator membrane between the anode and the cathode,
wherein the anode, the cathode, the first flexible separator membrane, the second flexible separator membrane, and the third flexible separator membrane are provided within a packaging layer to form a pouch cell, and
wherein the packaging layer forms an enclosure of the pouch cell; and
an electronic device embedded in, attached to, and/or printed on the packaging layer such that the flexible battery provides power to the electronic device,
wherein the anode and/or the cathode is self-standing and comprises a composite material having active material particles in a three-dimensional cross-linked network of carbon nanotubes,
wherein the anode, the cathode, the first flexible separator membrane, the second flexible separator membrane, and the third flexible separator membrane are folded inside the packaging layer,
wherein the packaging layer is flat and rollable along a plurality of battery axes, and
wherein the electronic device is attachable and detachable from the packaging layer of the flexible battery.
