An “origami battery” is an experimental energy-storage design built to tolerate folding or other deformation—not an ordinary battery that is safe to fold. The best-known example is a 2014 lithium-ion prototype folded into a Miura pattern; later research explored zigzag-folded lithium-ion cells, foldable zinc-air cells, stretchable designs, and even a moisture-powered fabric device. The reviewed sources describe research demonstrations, not a consumer product shown to be available for purchase.
What is an origami battery?
The term describes research architectures that use or accommodate folds, bends, twists, or stretches in the cell or its supporting structure. The aim is to let a device change shape without simply forcing a conventional rigid battery to deform. In some designs, a patterned structure helps manage where movement occurs so the active materials experience less strain.
“Origami battery” is not one chemistry or standardized product category. It can refer to lithium-ion or zinc-air cells, a kirigami-inspired stretchable design, or a moisture-powered fabric generator shown folded into an origami shape. Those examples work differently and should not be treated as interchangeable.
How the first widely cited origami lithium-ion prototype was made
In a 2014 study, researchers led by Zeming Song and Hanqing Jiang fabricated a lithium-ion battery by slurry-coating electrodes onto paper current collectors, packaging the device in standard materials, and folding it into a Miura pattern. The authors described the cell as deformable through folding, bending, and twisting; “unprecedented” was their characterization in the paper’s abstract, not a general measure of current battery technology. Nature Communications: “Origami lithium-ion batteries”.

The design distinction matters: the paper also reports that rigid origami can accommodate shape change while keeping patterned materials from experiencing large strain. The fold pattern is part of a purpose-designed experimental architecture; it does not make a standard rigid cell safe to crease or bend.
What the deformation test found
In the 2014 paper’s reported test, a conventional-material origami battery lost about 10% of its capacity after 100 cycles of linear deformation. In the same comparison, a device using carbon-nanotube-coated paper current collectors showed steady capacity. These results belong to those specific prototypes and test conditions; they are not a universal cycle-life rating for foldable batteries.

How later foldable and stretchable designs differ
| Research design | Architecture or deformation mode | Reported result |
|---|---|---|
| Origami lithium-ion, 2014 | Miura-pattern folding; slurry-coated electrodes on paper current collectors | About 10% capacity loss after 100 linear-deformation cycles for the conventional-material version; the CNT-coated-paper-current-collector version showed steady capacity in the same reported comparison. Nature Communications |
| Zigzag-like foldable lithium-ion, 2019 | Zigzag-like design intended to pack closely between energy-storage segments | Reported energy density was 96.4% of a conventional stacking cell; the study record also reports 275 Wh L−1 and 45,000 dynamic cycles at a 130° folding angle. These are figures for this design and its reported tests. Lingnan Scholars research record |
| Origami-foldable zinc-air, 2019 | Paper air-cathode architecture; zinc-air chemistry rather than lithium-ion | The cited source describes an origami-foldable/rechargeable Zn-air battery architecture; the cited record does not establish a directly comparable performance figure here. RSC Publishing |
| Kirigami-inspired stretchable battery, 2015 | Designed to extend beyond simple folding | Arizona State University reported that the research design stretched beyond 150% of its original size while maintaining functionality. Arizona State University News |
| Moisture-powered fabric device, circa 2022 | Fabric-based moisture-electric generator shown folded as an origami crane | The institutional account describes a self-charging device powered by moisture from the air; it is not another demonstrated lithium-ion chemistry. National University of Singapore |
Zigzag lithium-ion: packing and folding fatigue
The 2019 zigzag-like design addresses a different engineering question from the 2014 Miura-pattern cell: how to make a foldable battery fit efficiently between energy-storage segments. Its reported energy-density comparison and folding-cycle result should be read as measures of that design, not as benchmarks shared by every foldable cell. Lingnan Scholars research record.

Zinc-air: a different chemistry and electrode
A 2019 study describes paper air cathodes for origami-foldable and rechargeable zinc-air batteries. Because zinc-air cells use a different chemistry and electrode structure from lithium-ion cells, their folding concept does not make their performance directly comparable to the lithium-ion figures above.

Kirigami: stretching rather than only folding
The Arizona State University account describes a kirigami-inspired research design able to stretch beyond 150% of its original size while maintaining functionality. That result concerns extension in that specific prototype, not a claim that all origami batteries can stretch by the same amount. In the 2015 report, professor Hanqing Jiang said the type of battery “could potentially” replace bulky rigid batteries that limit compact wearable electronics; the statement expresses a possible application, not proof of deployment. Arizona State University News.
Moisture-powered fabric: an origami shape, not a foldable lithium-ion cell
A National University of Singapore account describes a fabric device powered by moisture from the air and shown folded into an origami crane. Its appearance connects it to origami, but the institution presents it as a moisture-powered “battery” or generator—not as another lithium-ion folding architecture. National University of Singapore.

Can you fold a battery?
Only if it is a purpose-designed experimental or commercial cell whose construction and manufacturer’s instructions explicitly allow the relevant deformation. The research examples here do not justify folding a regular battery. Bending, creasing, twisting, or puncturing a conventional cell can damage it; the origami pattern in a prototype is not a safe-use technique for consumer batteries.
Can you buy an origami battery?
The cited sources establish research demonstrations, but do not establish consumer retail availability, production scale, certification status, or a product that readers can buy. Treat the reported prototypes as research—not as purchasable batteries or validated drop-in replacements for rigid cells.

What the reported performance figures do—and do not—tell you
The figures measure different things in different designs: capacity retention under linear deformation, energy density relative to a stacking cell, dynamic folding cycles at a specified angle, or stretch beyond an initial size. The source set does not provide standardized head-to-head testing across all these architectures. A high cycle count or energy-density figure from one laboratory design therefore cannot establish how a consumer device would perform in everyday use.
