Pin spray as paint

One day, lithium-ion rechargeable batteries are being used in a variety of phones and laptops today that can be sprayed onto any surface like paint, helping mobile devices. more and more compact.

Even so, the batteries are about to be sold in stores that anyone can buy.

Lithium-ion batteries in most mobile electronic devices today are either cylindrical or rectangular.

Now, researchers have succeeded in creating batteries that can spray on a variety of surfaces, such as glass, stainless steel, plastic, ceramic, or even curved glass.

Neelam Singh, a materials scientist at Rice University in Houston, and colleagues spent more time creating paint that could act as a battery using materials such as carbon and charcoal powder. smooth. They paint these layers on the surface in layers in order to create batteries.

Batteries that scientists painted on eight ceramic tile panels can provide enough energy for 40 illuminated LEDs.

The coating material does not affect the operation of the device, suggesting that the technology can be applied to a variety of building materials and objects in the home.

However, the scientists said the battery uses some toxic, flammable and corrosive materials in a humid and non-oxygenated environment.

Scientists are applying for a patent before publishing details of the process of making paint.
