'Paint-on' batteries demonstrated

altResearchers have shown off a means to spray-paint batteries onto any surface.

Their batteries, outlined in Scientific Reports, are made up of five separate layers, each with its own recipe - together measuring just 0.5mm thick.

To demonstrate the technique, the team painted batteries onto steel, glass, ceramic tile and even a beer stein.

The approach will be of particular interest in industrial applications, as it is compatible with existing spray-painting technology.
