Batteries come in all different sizes, shapes, and are used for many different things. According to the article “Electric Vehicle” it states
“A battery is a container, or group of containers, holding electrodes and an electrolyte for producing electric current by chemical reaction and storing energy” (3).
There are two types of batteries, a primary and a secondary. A primary battery is a battery that can’t be recharged and is usually thrown away an example of a primary is carbon zinc or heavy duty. A secondary battery is simply the opposite, it is rechargeable. A battery has 7 major parts; container, cathode, separator, anode, electrodes, electrolyte, and collector. A container is the outside shell. The cathode is electrodes reduced by the reaction. The separator is what its name implies the separator of the electrodes. The anode is the oxidized electrodes. The electrodes are where the reaction takes place. The electrolyte is the medium for the movement of the ions. The collector is a brass pin that conducts electricity. A chemical reaction occurs inside the battery, than the electrodes oxidize and then the collector conducts the electricity formed and powers the device on. Inside a battery the type of reaction that occurs is exothermic because heat is released. Some batteries that are very used a lot are lead acid, lithium ion, nickel metal hydride, alkaline, and nickel cadmium.
A lead acid battery is used mostly in backup car battery, solar lighting and emergency lights and it is rechargeable but takes a long time to charge (approx. 8-16hrs). It is also one of the most popular secondary batteries. Since they are heavy they aren’t used in portable devices. The advantages of this battery are it is reliable, recyclable, it ...

Metals contain a sea of electrons (which are negatively charged) and which flow throughout the metal. This is what allows electric current to flow so well in all metals. An electrode is a component of an electric circuit that connects the wiring of the circuit to a gas or electrolyte. A compound that conducts in a solution is called an electrolyte. The electrically positive electrode is called the anode and the negative electrode the cathode.
These reasons are why Lithium-Ion Batteries are some of the most viable options when designing new gadgets. But, the structure of these batteries are why these batteries are being used for new gadgets. A Lithium-Ion Batt...
Another widely used primary cell is the zinc-mercuric-oxide cell, more commonly called a mercury battery. It can be made in the shape of a small flat disk and is used in this form in hearing aids, and electric wristwatches. The negative electrode consists of zinc, the positive electrode is of mercuric oxide, and the electrolyte is a solution of potassium hydroxide. The mercury battery produces about 1.34 volts.
...o do not have the ability to cruise or climb fast enough to compete with gasoline-powered cars and accessories, such as air condition or radios, drain the battery even more quickly. Another problem is the power required to recharge their batteries is generated at the same electric power plants that provide electricity for cities and towns.
In conclusion, the best type of battery varies depending on the certain situation. For instance, lithium-ion cells are best for cellphones while lead-acid cells are best for automobiles. Each type of battery has their own advantages and disadvantages, so sacrifices must be made. The chosen battery will depend on the design specifications and requirements.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
An electrode is a component of an electric circuit that connects the conventional wiring of the circuit to a conducting medium such as an electrolyte or a gas. The electrically positive electrode is called the anode and the negative electrode the cathode. If an anode and a cathode are placed in a solution of an electrolyte and a source of direct current is connected between them, the positive ions in the

From these batteries, the electricity goes to an inverter, which then changes the DC to AC or alternating current in order to use our modern electrical appliances and gadgets. There are two types of grid systems, which operate off solar panels, “off-grid” or “grid-tied”. My mom chose an off-grid system, which means we are independent of the public utility grid, DMEA, and don't have to pay any electrical bills and, if there’s sun, there’s always power.... ... middle of paper ... ...
Chemistry is used in our everyday life in more ways than we may think. One way that we use chemistry is in the batteries in our cell phones. They are solely responsible for the phone actually turing on and being powered to run. Most cell phones are powered with a rechargeable Lithium-ion battery. Lithium-ion batteries are commonly used in digital cameras and even in electric cars. These batteries are made of lithium cobalt cathode and carbon anode.
Now, what are electric vehicles really? Simply put, electric vehicles are vehicles that are powered by an electric motor instead of an internal combustion engine. Electric vehicles use electricity as the “fuel” instead of gasoline or some other combustible fuel. The electric motor in an electric vehicle converts electricity, usually from a battery pack, into mechanical power to turn the wheels. Major auto manufacturers are producing high-performance electric vehicles not only in the form of cars but also in a wide range of styles and sizes, including, mini-vans, sport utility vehicles and pickup trucks.

There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
