Paper battery A paper battery is an electric battery engineered to use a spacer formed largely of cellulose (the major constituent of paper). It incorporates [nanoscopic scale nanoscale] structures to act as high surface-area electrodes to improve conductivity. In addition to being unusually thin, paper batteries are flexible and environmentally-friendly, allowing integration into a wide range of products. Their functioning is similar to conventional chemical batteries with the important difference that they are non-corrosive and do not require extensive housing. Advantages The composition of these batteries is what sets them apart from traditional batteries. Paper is abundant and self-sustaining, which makes paper cheap. Disposing of paper is also inexpensive since paper is combustible as well as biodegradable . Using paper gives the battery a great degree of flexibility. The battery can be bent or wrapped around objects instead of requiring a fixed casing. A
