ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects‚ for example a galvanized nail and a copper coin‚ into an ion bridge (for example a lemon‚ a potato or paper soaked in salt water or acid). The copper coin serves as the positive electrode or cathode and the galvanized nail as the electron-producing negative electrode or anode. These two objects work as electrodes‚ causing anelectrochemical

ABSTRACT 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

Introduction Batteries are used every day in a variety of different devices. They allow us to charge an object and store power for later use. While batteries are a big part of daily human life they also present a challenge to society in terms of environmental sustainability. Not only do these batteries have harmful chemicals which can end up in landfills‚ but they also encourage over consumption because the more products you buy‚ the more batteries you need‚ and the more batteries must be produced
