One of the greatest challenges in the twenty-first century is undoubtedly energy storage. The depletion of non-renewable resources such as fossil fuels is inevitable. This can be simply arrived at due to the fact that it is a finite resource. Additionally, the rate of generation of fossil fuels far exceeds the rate of its depletion so much so that it is negligible in comparison. Thus the world today has been forced to search for a better energy source. According to Chen(2013), “Batteries are crucial to solve this problem [the energy crisis] as they can efficiently store electricity in chemicals and release it according to demand”(p. 156). Furthermore, the batteries used currently do not meet the demands of modern society, such as the need for reliable and safe power sources for a large variety of portable consumer electronic devices. According to Bruce(2005), “The performance of these devices depends intimately on the properties of their materials.”(p. 366). One of the major breakthroughs in the research for better battery materials includes the invention of the Lithium-ion rechargeable battery. Scrosati(2000)states, “Further breakthroughs in materials, not incremental changes, hold the key to new generations of energy storage and conversion devices” (p. 167). The main components of a battery are the electrodes, and the materials used for these electrodes have the greatest impact on the performance of the battery. Therefore, the essential question is: which materials used in the electrodes will yield to the most battery life?

The history behind the creation of the lithium-ion battery is as follows. Schalkwijk (2002) provides the reason behind why lithium was the chosen material for the battery, “(i) Lithium has the lightest wei...

...h various carbonaceous and non-carbonaceous compounds are presently under study, their performances are still to be fully ascertained, which makes graphite the most likely to be the anode of choice for the next few years. Economic and environmental costs can be reduced by the replacing of Cobalt with Nickel or Manganese in the cathode structure. Manganese provides a potential lower cost and has a less damaging impact on the environment in comparison with Cobalt and Nickel. Thus, Manganese will be the most likely to be used in the cathode. Furthermore, the batteries durability and reliability can be enhanced by replacing the liquid-like electrolyte with a plastic membrane which may act as both the separator and the electrolyte. Lithium ion batteries continue to be the object of intense research with the aim of further improving their properties and characteristics.

Redox Flow Batteries: A Load-Leveling Energy-storage System Essay

- Energy plays a critical role in the society of today, from the lights in your room to the medical equipment in the city hospital, human life depends greatly on energy production. Between the energy crisis of the 70s and the increasing carbon emissions in the air, renewable and alternative energy has seen increasing demand in research. While solar and wind plants are effective, they face challenges in their inability to hold excess power to be evenly distributed when required during maximum and non-maximum peak hours....   [tags: Redox Flow Batteries]

What are Batteries Made of? Essay

- A battery is a combination of multi-electrochemical cells which convert chemical energy to electrical energy in various electrical and electronic components. Each battery cells are made up of three parts namely, the two electrodes (positive and negative electrode) and a separator which contains an electrolyte solution. In particular, batteries use different material for the positive electrode (anode) and negative electrode (cathode). Different material will have different operating voltage range and characteristic due to the chemical properties of the materials itself....   [tags: battery, electrochemical cells, electrode]

Evaluating The Electrode Performance Of Metal Oxide Essay

- An effective way to optimize the electrode performance of metal oxide was developed by employing exfoliated 2D RuO2 nanosheet as a conducting additive. The exfoliated RuO2 nanosheet was easily incorporated into the Li−MnO2 nanocomposite via a simple mixing of exfoliated RuO2 and MnO2 nanosheets, followed by the restacking with Li+ ions. The incorporation of RuO2 nanosheet was found to be quite effective in increasing the surface area of the restacked Li−MnO2 nanocomposite. The obtained heterolayered Li−MnO2−RuO2 nanocomposites delivered much greater specific capacitances than those of the pristine Li−MnO2 and Li−RuO2 nanocomposites....   [tags: Oxide, Oxygen]

Alternative Technology : Alternative Fuel Technology Essay examples

- 3. Alternative fuel Technology 3.1 Introduction: It has been proven consistently that acquiring more efficient technologies and progressing to increase in usage of AFVs will slow the increasing demand for gasoline in comparison to past years. A recent study has also suggested that AFV 's will decrease energy consumption from 26.7 quadrillions Btu in 2012 to 25.5 quadrillion Btu by 2040.This gives positive attitude when another research suggests that the no of vehicle usage on roads is going to double by 2040.Since not all alternative fuels are well suited for all modes of transport, and not for all sectors within a specific mode of transport i.e....   [tags: Petroleum, Automobile, Alternative fuel, Coal]

The Architecture of Batteries Essay

- Introduction The battery architecture for our project had to be carefully considered and chosen. Three types of rechargeable batteries were looked at: Nickel-Metal hydride (NiMH), Nickel Cadmium (NiCd) and Lithium-ion (Li-Ion). Each type of battery architecture has advantages and disadvantages which had to be weighed before choosing which type of battery would best suit our project. A comparison table of the three battery types can be seen below. Lead acid batteries were not considered for this project as they are relatively heavy and storage for our system may be a problem if lead acid batteries were used....   [tags: charged, energy, self-discharge]
