In general batteries are into two categories. Primary batteries are non-rechargeable and are commonly found in consumer electronic products. Common primary batteries include zinc-carbon, zinc-alkaline-MnO2, zinc-air, and lithium batteries. Secondary batteries are distinguished by their ability to recharge. Examples include lead-acid, Nickel-Cadmium (NiCad), Nickel-Metal Hydride (NiMH), and Lithium-ion (Li-ion) batteries. For vehicular applications, secondary batteries are the preferred for power source or load-leveling devices. Other possible options include fuel cells and ultra-capacitors.
The energy density and power density provided by the different secondary battery chemistries as well as their cost are important factors for determining

The LiFePO4 batteries are the safest type of Lithium batteries as they will not overheat, and even if punctured they will not catch on fire. The cathode material in LiFePO4 batteries is not hazardous, and so poses no negative health hazards or environmental hazards. Due to the oxygen being bonded tightly to the molecule, there is no danger of the battery erupting into flames like there is with Lithium-Ion. The chemistry is so stable that LiFePO4 batteries will accept a charge from a lead-acid configured charger. Though less energy-dense than the Lithium-Ion and Lithium Polymer, Iron and Phosphate are abundant and cheaper to extract so costs are much more reasonable. LiFePO4 life expectancy is approximately 5-7 years. Lithium-Ion batteries and Lithium Polymer batteries are the most energy dense of the Lithium batteries, but they are lacking in safety. The most common type of Lithium-Ion is LiCoO2, or Lithium Cobalt Oxide. In this chemistry, the oxygen is not strongly bonded to the cobalt, so when the battery heats up, such as in rapid charging or discharging, or just heavy use, the battery can catch fire. This could be especially disastrous in high pressure environments such as airplanes, or in large applications such as electric vehicles. To help counteract this problem, devices that use Lithium-Ion and Lithium Polymer batteries are required to have extremely sensitive and often expensive electronics to monitor them. While Lithium Ion batteries have an intrinsically high energy density, after one year of use the capacity of the Lithium Ion will have fallen so much that the LiFePO4 will have the same energy density, and after two years LiFePO4 will have significantly greater energy density. Another disadvantage of these types is that Cobalt can be hazardous, raising both health concerns and environmental disposal costs. The projected life of a
Table 3.2, located below, shows the battery pack characterization. The table shows the voltage of the battery and the current through the battery as a function of time.
Energy storage is a means of storing energy for future use and can be accessed when needed. Storage can also make the power more solid or resilient so that it can be managed easier. According to Lockheed Martin “The GridStar Lithium-ion system can help customers reduce electric bills, help utilities defer costly transmission and distribution infrastructure upgrades, and enable the integration of behind-the-meter customer renewable electricity production” (Corporation,

Polymer electrolyte membrane fuel cells operate at relatively low temperatures, around 80°C (176°F). Low-temperature operation allows them to start fast (less warm-up time) and results in less wear on system components, which result in better durability. However, it requires that a noble-metal catalyst (typically platinum) be used to separate the hydrogen's electrons and protons, adding cost to the system. PEM fuel cells are used primarily for transportation applications and some stationary applications. Due to their fast startup time, low sensitivity to orientation, and favorable power-to-weight ratio, PEM fuel cells are particularly suitable for use in passenger vehicles, such as cars and buses. A significant barrier to using these fuel cells in vehicles is hydrogen storage. Most fuel cell vehicles (FCVs) powered by pure hydrogen must store the hydrogen on-board as a compressed gas in tanks. Due to the low-energy density of hydrogen, it is difficult to store enough hydrogen on-board to allow vehicles to travel the same distance as gasoline-powered vehicles before refueling. This increases costs and maintenance. They deliver high-power density and offer the advantages of low weight and volume, compared with other fuel cells. 3.3 PEMFC structure
In an “electrolytic solution”, if two electrodes, one being positive and the other negative, are placed in the solution then ions have the ability to transport free electrons to and from both of the electrodes. Acids in a solution are good electrolytes since the acids supply the solution with hydrogen ions. If a solution contains organic compound has sugar or starch, then that solution won’t conduct electricity well since organic compounds are contributing as many hydrogen ions as acids. The most familiar electrolytes would be elements such as potassium, calcium, sodium, and magnesium. Lithium-ion batteries are commonly used in many household as a source of energy, however the battery relies heavily on liquid electrolytes which are flammable and are prone to fires.Researchers at Oak Ridge National Laboratory has created a solid electrolytes that is made out of lithium triphosphate to try to overcome the safety issues presented by lithium-ion
This is the most common battery that people use today like Energizer or Duracle batteries. The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through the center of the cell. This rod is surrounded by a mixture of carbon and manganese dioxide. This battery produces about 1.5 volts.
Battery powered cars are more complex than they sound. One might think that the mechanics behind battery power merely consist of charging the battery before a road trip. There is actually an entire process that transforms energy into power. Whereas a gasoline powered vehicle uses an internal combustion engine to convert gasoline into energy, battery powered vehicles generate...
Standard testing and upkeep enhances its life and improves efficiency. With the colder climate battery failure becomes far more frequent. As automobile emissions are a single of the key sources of greenhouse gases, men and women must discover ways to minimize their quantity. According to ConsumerReports.orgs Automobile Weblog, To see a map of shared outlets in a given location, drivers enter a destination. We don’t even recognize that – take the most widespread and clear issues – vehicles, golf carts, digital cameras, laptops and so many factors they all involve batteries! As the name suggests, these charges work on the power generated from the sun, which is also named solar energy. To do this you should disconnect the battery once more of course. By obtaining a single of these units you will not have to bother with that, as it will constantly maintain charging your battery for your entire fishing trip.You can also use solar trickle chargers during the winter months, so that your batteries are constantly charged u...
The lead acid battery was first discovered and invented by a French physicist called Gaston Plante in 1859. The lead acid battery was the first type of battery that was rechargeable.
For example, different types of ceramic and polymeric materials for electrodes and electrolytes have been developed to make both types of supercapacitors. Conducting polymer based super capacitors using proton and lithium ion conducting solid electrolytes have received considerable attention recently and several supercapacitor modules have been fabricated using polythiophine, polypyrrole, polyaniline and their related composites to achieve energy storage of about 200F/g. Generally the voltage of a super capacitor is dictated by the available potential window prior to the commencement of any irreversible anodic and cathodic faradaic processes. The range with aqueous systems is about 1.23V, but can be extended by a judicious choice of the supporting electrolyte or a solvent with high anodic and cathodic properties likewise over potential for the appropriate irreversible anodic and cathodic faradaic reactions. At present, the development of today’s non- aqueous systems outcome to be gaining a lot of momentum because of the increased energy density of such systems. Gel electrolytes hold the reliability of combining the favor of solid polymer electrolytes with the increased voltage of non-aqueous systems. Without any comments, only the carbon and the RuOx systems have so far been commercialized, while
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 ... ...
In recent years, electrochemical supercapacitors (ECs) have been extensively studied as attractive energy storage devices. They have potential applications in portable electronics and electric vehicles because of their high power energy densities and long cyclic life [8, 101, 102]. Based on the nature of the charge-storage mechanism and active materials, electrochemical capacitors can be classified into two types: electrochemical double layer capacitors (EDLCs) and redox supercapacitors (pseudocapacitors). EDLCs utilizing carbon-based active materials, such as activated carbon (AC) and carbon nanotubes (CNTs) with charge stored at electrode-electrolyte interface, are currently the most commonly used devices [2]. On the other hand, pseudocapacitors or redox capacitors use fast and reversible faradaic surface reactions for charge storage. Conducting polymers [103, 104] and transition metal oxides and hydroxides [81, 105, 106] have been investigated as possible electrode materials for redox capacitors. Redox capacitors have drawn much more attention than EDLCs due to their high theoreti...
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.

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.
