Researchers have created paints that form a lithium-ion battery when layered together - lithium ion polymer battery

Researchers have created five types of paint that can be sprayed to form lithium-
When ion batteries are layered together, it may allow you to store energy on walls, tiles and even your favorite cups.
The normal battery contains a positive and negative electrode, both paired with the metal current collector with a polymer separator in the middle clamp.
The five layers are usually made of thin sheets and rolled into a cylinder, which makes it difficult to make extremely thin batteries.
Now, Neelam Singh of Rice University in Houston and his colleagues have used a combination of existing metal coatings and custom materials to create a spray-able version for each layer, allow them to spray these layers onto one surface at a time to make a small part of the battery that is only mm thick.
The team applied their batteries to a variety of common building materials, even ceramic cups, to test their potential.

They haven't matched the normal battery yet.
It takes about 1 battery to paint.

But it will improve.
"If produced on an industrial scale, their capabilities, efficiency and performance can be greatly improved," Singh explained . ".
Pairing the batteries with the recently developed spray-painted solar cells could bring exciting modifications to your walls, but Singh says the paints are not fully ready for home use as they haveand oxygen-
