The rechargeable lithium-ion batteries now found in many mobile phones and laptops may one day be sprayed like paint onto virtually any surface, potentially ushering in a new generation of thin, flexible devices, researchers say.
Spray-paintable batteries even might become available to the general public someday at hardware stores, the scientists added.
Lithium-ion batteries power most portable electronics nowadays, but their spiral, jelly-roll-like design generally limits them to rectangular or cylindrical shapes.
Now researchers have succeeded in painting these batteries onto a diverse range of surfaces, including glass slides, stainless steel, flexible plastic sheets, glazed ceramic tiles, and even the curved side of a beer mug.
“We can convert almost any object to a battery,” Neelam Singh, a materials scientist at Rice University in Houston, told InnovationNewsDaily. More:
