Origami lithium-ion batteries

Abstract

There are significant challenges in developing deformable devices at the system level that contain integrated, deformable energy storage devices. Here we demonstrate an origami lithium-ion battery that can be deformed at an unprecedented high level, including folding, bending and twisting. Deformability at the system level is enabled using rigid origami, which prescribes a crease pattern such that the materials making the origami pattern do not experience large strain. The origami battery is fabricated through slurry coating of electrodes onto paper current collectors and packaging in standard materials, followed by folding using the Miura pattern. The resulting origami battery achieves significant linear and areal deformability, large twistability and bendability. The strategy described here represents the fusion of the art of origami, materials science and functional energy storage devices, and could provide a paradigm shift for architecture and design of flexible and curvilinear electronics with exceptional mechanical characteristics and functionalities.

Toward Soft Skin‐Like Wearable and Implantable Energy Devices

“…The origami design of stretchable batteries was recently reported through Miura folding, shown in Figure 4a. [30] Many identical parallelogram faces were connected by 'mountain' and 'valley' creases. Depending on the difference in [24] Copyright 2013, The Royal Society of Chemistry.…”

Self‐Healing Materials for Next‐Generation Energy Harvesting and Storage Devices

“…[139][140][141][142][143] The low stretchability can be attributed to the unavoidable crack generated in rigid electrodes during repeating stretching process, which leads to the degradation or even loss of electrochemical performance of Li-ion batteries. As discussed above, the Si electrodes with self-healing polymer binder could withstand the generated stress and heal cracks inside the electrodes, providing a promising platform to design the stretchable Si electrodes for Li-ion batteries.…”

Flexible and biocompatible high-performance solid-state micro-battery for implantable orthodontic system

“…On the contrary, recent research efforts establish an impressive alternatives to commercially available cylindrical, coin, prismatic, and pouch cells with flexible and stretchable batteries. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Nevertheless, such advances do not address the major necessities for implantable devices, especially in orthodontic dental implantations, which generally require: smaller footprint, lightness, high bio-compatibility, and finally integration strategy with other circuit components. Here, we show, a high yield, transfer-less method to achieve a bio-compatible, flexible, high-performance solid-state, micro-battery for wearable and implantable device electronics, specifically with an example potentially disruptive for orthodontics applications.…”
