Exploring Issues In Electrochemistry: Lithium Or Hydrogen

1442 Words6 Pages

Exploring Issues in Electrochemistry: Lithium or Hydrogen? Unit 5: Electrochemistry SCH4U Yasmin Hashi May 14, 2018 Exploring Issues in Electrochemistry: Lithium or Hydrogen? Gasoline powered vehicles outnumber the amount of cars that are alternative powered. The combustion of fossil fuels like gasoline is considered a major source of air pollution and a contributor of climate change. Gasoline is an extremely flammable and very toxic liquid. This causes automotive experts to think that gasoline-powered vehicles will go extinct by the near future. Gasoline prices have started to increase and so have new alternatives as an energy source for future vehicles. There are two alternatives that have potential to be used as sources …show more content…

In contrast to gasoline powered vehicles, fuel cell vehicles completely run off of electricity and its by-products become water and heat thus meaning fuel cell vehicles don't emit emissions that could cause pollution unlike gasoline powered vehicles (Union of Concerned Scientists, 2018). The energy in 1 kilogram of hydrogen gas is about the same as the energy in 2.8 kilograms of gasoline. Hydrogen fuel cell vehicles can run more miles than gas or solar-powered vehicles.Fuel cells are a more efficient alternative and they are able to reduce the use of of other fuels and prevent oil depletion since hydrogen is an abundant element in nature .It can also help establish independence and decrease the dependence on oil producing countries. The maintenance of fuel cells is easy because of how simple and few moving parts in the system there are. Another advantage would be that hydrogen is readily available and accessible ( Fuel Cell Today, …show more content…

Although both types of vehicles are efficient from their sources, hydrogen fuel cells would be more environmentally friendly due to the efficiency of how long it powers the vehicle for. Hydrogen is the lightest element and most abundantly found everywhere, unlike the materials that make up lithium ion battery so it is the most ideal choice to use (The independant, 2017). Hydrogen fuels, in addition to being lightweight, they also take up less space ad generate fewer greenhouse gas emission. It takes fewer time to refuel and maintain and also has a significantly lower cost rate. It’s best to use hydrogen fuel cells due to their advantages over lithium batteries which make it more favorable when using (Yue,

Unlike traditional gasoline vehicles, electric cars do not have any in-use emissions. This drastically reduces the emissions we emit into the earth. To put this in context, “burning 1 gallon of gasoline pushes more than 19 pounds of CO2 out of your vehicle’s tailpipe”(Kliesch). As many know, gases like CO2 are classified as greenhouse gases. These gases trap heat inside the earth which causes the phenomenon known as global warming.

The Pros And Cons Of Lithium Ion Battery

184 Words | 1 Pages

Lithium ion battery store and release energy by moving electrons from the negative side to the positive side of the battery. When electrons flow through an electrical circuit, they power our electronic devices. It is the same idea as watermill. The watermill uses water flow to spin a wheel that drive a mechanical process such as milling and grinding. Since the electrolyte separates the two lakes, water can only flow is through the water pipeline. The giant hippos cannot go through the water pipeline, so they have to walk past the electrolyte terrain into lake Cathode in valley.

Gasoline and diesel are fossil fuels and aren 't infinite. Battery electricity are better, they don’t pollute and don 't burn fossil fuels. Instead of having a gas tank and having to fill it up at a gas station, these cars have batteries in their place and can be recharged with a larger charging station and needs 220 volts. The recharged batteries stay charged until the car is driven. Some people say that battery powered cars are slower, but it isn’t by much and battery powered cars think is worth slowing down a little if it means saving the planet.

A lot of people love to hear about energy efficient and environmentally friendly options out there. The electric vehicles today serve great benefits in keeping emissions down and using a more friendly alternative energy source. In my opinion they have made an impact on the environment, but a major benefit in using this alternative resource is less cost to fuel the vehicle. Gasoline is very expensive today, and using the energy that is used to power our home, is much less expensive and more available than gas. The environment, as claimed by environmentalists, suffers due to the emissions of automobiles today.

Hybrid vehicles, or more specifically hybrid-electric cars, have been the centre of debate since the premier models made their debut back in the 1990s. Environmental activists have been quick to advocate the perks in terms of reduced emissions of greenhouse gases. On the other hand, critiques argue if the costly hybrid technology is worth the savings in fuel cost over the long-haul. Hybrid vehicles use two or more distinct power sources that work in tandem in order to create power. While there is a wide assortment of vehicles that run on hybrid power sources today, cars enjoy the most popularity among consumers.
