there were batteries slim‚ flexible and also powerful enough to run the gadgets. The batteries‚ it turns out‚ are the main barrier to modern electronics design. But in a small‚ brightly lit lab in an office park behind the Oakland Airport in Alameda‚ Calif.‚ a young startup called Imprint Energy‚ is using research created at the University of California‚ Berkeley to develop just such a battery that could free gadget makers from the constraints of the standard lithium ion battery. Well‚ that’s

using more and more household batteries. The average person owns about two button batteries‚ ten normal (A‚ AA‚ AAA‚ C‚ D‚ 9V‚ etc.) batteries‚ and throws out about eight household batteries per year. A battery is an electrochemical device with the ability to convert chemical energy to electrical energy to provide power to electronic devices. Batteries contain heavy metals such as mercury‚ lead‚ cadmium‚ and nickel‚ which can contaminate the environment when batteries are improperly disposed of. When

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

POTATO BATTERY Abstract a. Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we removed the shell of a broken AA battery for our Zinc electrode. (Make sure to test your multimeter by connecting its Positive and Negative

and unpredictable nature of the conventional chemical batteries‚ along with the frequent replacements that they require‚ has created an acute need for a reliable‚ longer-lasting and rugged source of energy. Moreover Radars‚ spacecrafts‚ interstellar probes and other advanced communication devices require much larger power than that can be met by conventional energy sources. The solution to long term energy source is the nuclear powered batteries which have a life span of few decades and can pack in
