Technology Essay Ali
Battery Only once in a lifetime will a new invention come about to touch every aspect of our lives. An important technology integrated into our society and around the world is the invention of of the Battery. Among many inventions of our modern world, the battery stands out as an amazing on going development with its effect on almost every portable electric powered device. An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy. The primary, and arguably most noble, intent of the battery is to assist in mankinds pursuit of practicality. Electricity had always fascinated human kind since our ancestors first witness of lightning. In ancient Greece, Thales observed that rubbing amber, for which the Greek word is electro, could generate an electric charge. In 1938 a jar was found just outside of Baghdad, Iraq that may be or could be the first battery. Nowadays battery is used to power, advanced machine, electric appliances and majority of electronics that are integrated to mankind. Having fulfilled its duty to provide practicality for human to operate electronics, the battery could be titled as one of the most i mportant mportant inventions inventions ever made. There are currently two types of battery, disposable batteries which are designed to be used once and discarded when they are worn out,and rechargeable battery which are designed to be recharged and reuse until their ability to store electrical energy decrease drastically. Normally a battery such as the AA, C or D has two terminals, one is marked positive and the other one is marked negative. In a battery, electrons collect on the negative terminal of the battery. The electrons will flow from the negative to the positive terminal as fast as they can. Normally, you connect some type of load to the battery using a wire, without any load the battery will wear out very quickly.This also tends to be dangerous, especially with large batteries. With the consumption of energy increasing from time to time, the battery industry is one of the worlds most leading industries. The rapid growth of advanced technology made it inevitable for batteries to not develop more and more. Researchers all over the world are using the battery technology to make a more environment friendly energy source. The battery has the ability to store an amount of energy based from their types; this kind of energy source could be integrated integrated into heavy machineries thus replacing the use of non-renewable power sources that are not environment friendly. Batteries are considered environment friendly because of its production method. There are two ways to store energy into a battery; one is by formulating a certain chemical reaction, and two is by charging it. Through the charging method, it only takes a transfer of electric energy from another power source. Factories like
Energizer and Alkaline that produce battery usually has direct access to a powerplant, mostly hydro or thermal plant that does not create an enormous pollution. Basically the growth of the green energy and electronics industries essentially depends on the advancement of battery. The advancement of battery has grew to the stage where it has powered nearly everything starting from home appliances to cars and self charging or wireless charging battery. The visible development of battery began in the seventeen hundreds when Italian physicist count Alessandro Volta built his first Voltaic Pile.It was not until the nineteen hundreds that battery entered the open market, since then the open access to battery have been leading mans conquest for practicality. Speaking of practicality, wireless battery charging did indeed exist, and several companies had products on the market to provide wireless charging capability. Wireless battery charging technology could better be termed ascordless recharging. It involves the use of electromagnetic induction, which means that the device being charged needs to be in contact with the charger. Researchers have proposed the development of systems, which could transmit usable energy within a small radius for truly wireless battery charging. Devices equipped with receivers could intercept the energy and harvest it to recharge their batteries. Another great use of battery in the automotive world is to be the environmental friendly alternative to gasoline, battery or electric cars creates less pollution than gasoline powered cars. Large automobile companies like Nissan and Toyota have been the largest producer of electric cars.Electric Cars use the energy stored in a battery for vehicle propulsion. Battery powered vehicles can basically be charged anywhere, especially when wireless charging is available for consumer. We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta's pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. For three hundred years the advancement of battery have been the key to energy solution and so will for the years to come.
