Swedish scientists are currently trying to develop a light, eco-friendly, and inexpensive batteries consisting entirely of nonmetal parts, and they called it paper battery. That's right, paper battery! This battery is made of cellulose, the stuff of paper.
According to the scientists, this new type of battery has many benefits. It recharges faster than conventional rechargeable batteries and appears well-suited for applications involving flexible electronics, such as clothing and packaging.
One potential application of this battery is to light up wrapping paper with words like "Happy Birthday" or "Happy Holidays."
