1. PAPER BATTERY
1.1 INTRODUCTION Traditionally, electronics have been designed around their batteries. The batteries form a significant part of many electronic devices. Typical electrochemical batteries or cells convert chemical energy into electrical energy. Batteries based on the charging ability are classified into primary and secondary cells. Secondary cells are widely used because of their rechargeable nature. Presently, battery takes up a huge amount of space and contributes to a large part of the device's weight. There is strong recent interest in ultrathin, flexible, safe energy storage devices to meet the various design and power needs of modern gadgets. New research suggests that carbon nanotubes may eventually provide the best hope of implementing the flexible batteries which can shrink our gadgets even more. A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and supercapacitor, combining two components that are separate in traditional electronics. This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies. The paper we use is made of pure cellulose, which is the natural polymer that is found in wood and other plant materials. Normal paper that you use in school is made from small fibers of cellulose along with bleaching compounds and binders (glue), but the “paper” we use is not fibrous, it is a smooth sheet of pure cellulose, with small pores that allow the for the lithium to move from one side of the battery to the other.
