Review on How to Improve the Efficiency of the Rechargeable Batteries-Lithium Batteries
Lai Jee Inn GS42146
ABSTRACT

Batteries are playing important role in our life especially in this high technology era. Laptop, mobile phone, camera and otherwise are using battery to make it to function. In order to improve the efficiency the batteries, several methods are discussed in this paper. INTRODUCTION
In this advanced technology era, batteries have been commonly used by the consumers. We use them in different fields like cars, mobile phone, laptop and other else. (Hiroki Kitamura, 2012).Batteries is divided into two main groups which are primary and secondary batteries. (Clean Up Australia, 2009)

Primary batteries are the batteries that normally use in dairy life such as remote control, clock but for this kind of batteries is a non rechargeable battery which means that we only can use it for one time and will be throw away after used. This kind of batteries is actually converting the chemical energy to electrical energy and they are normally known as the alkaline batteries. Secondary batteries are batteries that can be rechargeable and recycle after it cannot be recharge. This batteries mostly use for our mobile phone, laptop and other. Although these two kinds of batteries have it own advantages and disadvantages but consumers still using them. As we know that the materials inside the batteries is harmful and toxicity. Therefore, consumers started to require more advance batteries which have long life span and more environmental friendly.

An electrolyte is a medium that allow the ions to flow in between the cathode and anode.…...

...Batteries, Resistance and Current (Giancoli CH 18) Prelab: 1. Batteries are made by the difference in the electronegativity of different metals. Electrons can flow spontaneously between metals that give off electrons easier to metals that are less likely to give off electrons. There is a substance between these metals that allow charge to flow (salt bridge) so net charge doesn’t build up and “turn off” the battery. Draw a diagram (use your text) of an alkaline battery showing the + terminal, - terminal (and the type of metals used), the direction of current (+) flow and what’s inside. 2. What is the resistivity () of a resistor? What characteristics of a resistor affect the resistivity? Write a formula for this relationship, label each variable and indicate the units used to measure each. Would resistivity be constant for a specific resistor? 3.

...the Battery Could you imagine a world where every electronic device we owned has to be plugged into a wall socket in order for them to be able to be used and keep a charge? This would be very inconvenient. Mobility is important as well as very useful in our lives and therefore; it would only seem right that someone invented a way for our electronic devices to keep a charge without being constantly plugged into a socket. This man’s name was Alessandro Volta and he created the first battery in 1799, although there has been evidence of “clay pot” batteries dating back to 200 B.C. In order for an electronic device to be functional, electrical energy must be produced. In 1799, Physicist Alessandro Volta realized this reaction called “electrochemical reaction” is necessary in producing electrical energy and he was able to create the first battery by using an arrangement called the voltaic pile, in which he stacked alternating layers of zinc, brine-soaked pasteboard or cloth and sliver which created a steady, lasting current. This method has been improved throughout the years and is now made of many different materials and come in many different sizes and shapes. The next improvement on the battery did not come until 1836 when the Daniell cell was invented. This type of battery was invented by chemist John Frederick Daniell and was a way to power doorbells and telephones. In 1898, the battery called the Colombia Dry Cell was the first commercially used battery in......

...Final Investigatory Project for Group 5 I. Problems and Setting A. Introduction Batteries, years ago, have taken the world by a storm and have since than became a necessity in one’s household. Sadly, even though they are tremendously useful, batteries have drawbacks, such as semi- affordable costs, limited shelf life and pollution. Our group had an idea on how to make an alternative to this that would not only work like the real thing but would also be healthy to our environment and light in our pockets. This idea turned out to be realty and became the main goal of our Investigatory Project. B. Problems Finding an item that is easy to obtain and at the same time affordable, simple and earth- friendly is not an easy task. After a lot of thought, our group decided to use one of the objects that is almost always present in our daily lives: fruits and vegetables. Will these everyday materials such as apples, bananas, oranges, lemons and potatoes conduct electricity? Well, let’s see about that. C. Hypothesis A circuit is made up of a path, a source and a load. We believe that we should connect them with a (+) and a (-) wire so that the flow will be even with no reverse polarity. The load we thought of using was a battery- operated clock, one of the most common materials found in almost everyone’s household. We believe that it would work because the organic materials we will use have electrolytes that flow freely on its own. Thus, it will flow into conductors to......

...metal cylinders that power our lifestyles; our televisions, radios, CD players, portable phones, and clocks. Our cars, planes, and even our homes are no exception, they too contain devious contraptions of metal, acid, and wire. Even the hearts of our vice presidents are not free from the hidden enemy. Thousands die daily, but millions more take their places; they are silent, hidden from our eyes. Waiting for revenge. The battery rebellion is almost at hand, but it has been in the making for hundreds of years. While technically a battery is an energy storage system, most people refer to a battery as a chemical/electrical system, rather than any object with potential energy (a flywheel, a spring, a piece of firewood, or a bucket of water). Chemical electrical batteries work through a redox chemical reaction, short for reduction oxidation (the same reaction behind other tried and true human inventions like fire). Basically, an electrical current is generated when oxygen ions are mercilessly ripped from one molecule and forced upon another. A simple battery must then contain three things; two different materials (with contrasting oxidation potentials) and an electrolyte - the material which links the previous two and encourages the violent and unjust treatment of oxygen ions. You, the suspicious and disbelieving soul, can test this out by mercilessly sticking a lemon with a strip of copper and a strip of zinc. The copper and zinc are the anode and cathode, and the lemon......

...know energy for providing us light and comfort. It can help us to cool down during summers and feel warm during winters. It also helps us to go from one place to another. There has been an enormous increase in the global demand for energy in recent years as a result of industrial development and population growth. Supply of energy is, therefore, far less than the actual demand. Wherefore, the great bottleneck in the supply of energy resources to an economy caused energy crisis. We all know that our world today is now facing energy crisis. Everyone is trying to do something and solve that about that problem. In this study, we can prove that electricity can be produced by vinegar. After all, vinegar is abundant everywhere. A battery is an electrochemical device that converts chemical energy to electrical energy. It contains thousands of charges (protons & electrons). It is also defined as a container consisting of one or more cells, in which chemical energy is converted into electricity and is used as a source of power. Likewise, vinegar is a liquid consisting mainly of acetic acid and water. It is produced from the fermentation of ethanol into acetic acid. The fermentation is carried out by bacteria. Because different metals have different levels of attraction for their electrons, one of the metals would lose electrons, a process which chemists call oxidation, and the other gains electrons, which is called reduction. The metal being oxidized is called the......

Background of the study 1.5 billion people do not have access to electricity, 585 million of them living in Sub-Saharan Africa and 404 million in India. Three billion people, almost half of the world's population rely on biomass, such as wood, charcoal, and dung for cooking and heating purposes. Sub-Saharan Africa is an especially dire case, Only 31% of the population has access to electricity and the Sub-Saharan Afican population (excluding South Africa) of 791 million consumes as much energy annually as New York State, a population of 19.5 million, according to a recent IEA and UNDP report. This project of ours is to help the problem of factories that produces metals for electrical purposes. (Natalie Relich, 2011) Everyone can make this salt water battery, especially poor people who are living in rural places in the Philippines that has no access to energy. Because now some of electrical company can't reach their area. They can use this project to conduct electricity in case of emergency like using small light bulbs to......

...The usage of "battery" to describe a group electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of cannon[2] (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together[3]). Alessandro Volta described the first electrochemical battery, the voltaic pile in 1800.[4] This was a stack of copper and zinc plates, separated by brine soaked paper disks, that could produce a steady current for a considerable length of time. Volta did not appreciate that the voltage was due to chemical reactions. He thought that his cells were an inexhaustible source of energy,[5] and that the associated corrosion effects at the electrodes were a mere nuisance, rather than an unavoidable consequence of their operation, as Michael Faraday showed in 1834.[6] Although early batteries were of great value for experimental purposes, in practice their voltages fluctuated and they could not provide a large current for a sustained period. The Daniell cell, invented in 1836 by British chemist John Frederic Daniell, was the first practical source of electricity, becoming an industry standard and seeing widespread adoption as a power source for electrical telegraph networks.[7] It consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.[8] These wet cells used liquid electrolytes, which were......

Submitted in partial fulfillment of the requirements in Research 1 Alubijid National Comprehensive High School Special Science Class Alubijid, Misamis Oriental January 8, 2014 Mrs. Ma. Romila D. Uy Research Adviser Abstract Battery is a device used to store electrical energy. Battery can also be called a cell in which the reaction between two different substances can be made to occur in such a way that some of the chemical energy is converted into a useful electricity. Since its invention and inception, battery has become the most common power source for many household and industries. The vinegar battery is constructed out from simple components or materials. Adding an amount of vinegar to a strip of different metals like copper, from copper wires and zinc, from nails can form a simple battery. This battery has a low amperage output which can supply power on a low amperage/low voltage device like a calculator. It is easy to construct. The following steps should be followed in constructing the vinegar battery: 1. Prepare all the materials needed like: * Vinegar * Strip of Zinc from nails * Strip of copper from copper wire * Vinegar container (non-metallic) * Multi-tester 2. Place the vinegar inside the container. Make sure that it is deep enough to suspend the two different metals on it. 3. Cut a piece of......

Vinegar Battery

...Home-made Vinegar Battery A b s t r a c t An electric battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode, and a negative terminal, or anode. The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. The terminal marked positive is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, Electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work. Although the term battery technically means a device with multiple cells, single cells are also popularly called batteries. There are many ways to construct a battery, as well as ways to control its generated output. Almost any liquid or moist object that has enough ions to be electrically conductive can serve as the electrolyte for a cell. This homemade battery is based on two different metals suspended in an acid solution. You’ll need two different kinds of metal, like copper and zinc nails and some acid liquid. The copper is the + and the nail is the -. The electrons travel from the – through the vinegar (acid) to the +......

... Servicing Lead Acid Battery Aizat Hizami Bin Abu Bakar, Unikl MIAT, aizathizami@gmail.com Abstract—These articles is about servicing one of the type of battery which is Lead Acid Battery. In time, batteries’ capacity may decrease due to the way we handle the battery thus proper way of servicing and charging of the battery is necessary. The capacity of the battery can be maintain through the process of servicing below. Index Terms—Battery I. INTRODUCTION O NE of the most important aspects of battery servicing is to keep the battery clean and all the terminals tight and free of corrosion. If any corrosion exists on the battery terminals or within the battery box, it should be removed. One way to do this is by scrubbing the battery box and the top of the battery with a soft bristle brush and a solution of sodium bicarbonate (baking soda) and water. When washing the top of the battery, avoid getting any baking soda in the cells since it neutralizes the electrolyte. After the battery and box are clean, rinse them with clean water and dry thoroughly. Coat the battery terminals with petroleum jelly or general purpose grease, and touch up any paint damage to the battery box or adjacent area with an acid-resistant paint. A lead acid battery goes through three life phases, called formatting, peak and decline are shown in Figure 1. Fig. 1. Cycle life of a battery In the formatting phase try to imagine sponge-like lead plates that are being exposed to a liquid.......
