2.1. Na-ion Batteries (NIBs) Na-based batteries are not new. Back to the 1970s, Na-ion and Li-ion batteries were investigated in parallel.5,6 The investigation of Na-ion batteries significantly decreased after the success of commercial application of Li-ion batteries in the 1990s. Na-ion batteries have a very similar working principle as the Li-ion batteries. As shown in Figure 2.1, each electrochemical cell is basically composed of a positive electrode, a negative electrode, and a membrane…
As the world population increases day by day, so energy consumption rises also due to the industrial development there are more and more power needs to run these industries and factories. Conventional resources for energy are coal, natural gas, etc. they are form in millions of year so they take long time for their generation so there is need of energy resource that can balance the energy needs and there time of generation. If we take into account the world energy resources then sun would be the…
In my point of view nuclear power plants are bad.But there are pros about them and i am going to tell you some of them.One of them is low air pollution it has low air pollution because most the pollutants are going into water because of cooling the nuclear reactor.Another one is low operating cost.It has a low operating cost because the things used are natural and are from dead animals in the environment. Another pro is a reliability to people and their homes.People need this…
disarmament in the discussion on nuclear weapons, mean? Nuclear weapon is an explosive device that is used as a disinfectant such as is happening in Palestine now. It stems from the destructive power supplied from nuclear reactions whether he fission or a combination of fission and fusion. Since the enactment of the bombing of Hiroshima and Nagasaki, these explosive weapons used more than two thousand times for tests and demonstrations. Due to these highly dangerous nuclear weapons, only a few…
spectrum is relatively concentrated in yellow and the color temperature is 2000 to 2500 kelvins through and strong and fog. Comparison on environmental protection and energy saving The LED hibay lights are energy efficient and they have ultra low power consumption. The energy white LED is only a tenth and a quarter in an energy saving incandescent lamp. The LED light source does not have any harmful metallic mercury. The high pressure sodium lamp light source metal containing mercury, sodium…
In recent years, wind energy has become the fastest growing electrical power source and expected to be widely adopted in the future as wind energy is the most renewable and green energy source in natural resources. The fact is that the cost of energy supplied by wind turbines are continuously…
be replenished. (but as it is not a renewable energy once they are exhausted they cannot be replenished) Therefore, scientists from around the world have researched the use of other energy resources to continue moving the world, such as solar and nuclear energy, which are two main areas of research. However, there are other energies, less known and therefore less used, like biogas. Biogas is a renewable (source of) energy that belongs to the category of biofuels. It typically refers to a gas…
History Speech – Coal Seam Gas Introduction: (Intro to CSG/What are the two sides?) Good morning, I am here to advise you on the coal seam gas development and the issues surrounding it. Now what, what is Coal seam gas. Well coal seam gas also commonly known as CSG is a natural gas that is produced and trapped underground by water and ground pressure. The gas is harvested and extracted by drilling vertically into the ground, until a gas deposit is reached. The suppliers of CSG earns millions…
Maule Earthquake One of the largest Earthquakes in the world occurred on February 27, 2010. This Earthquake, known as the Maule Earthquake, took place on the offshore of Bio-Bio Chile with a magnitude of 8.8 (“Aftershocks of Chilean Earthquake”). Even with all the damage and destruction caused by the earthquake, the offshore of Bio-Bio, Chile was in for more destruction by the tsunami that shortly followed Maule Earthquake. As a result, Chile was impacted by the earthquake politically,…
energy. Fossil fuels are defined as a natural fuel, such as coal or gas, formed in the geological past from the remains of living organisms. Renewable energy is defined as energy from a source that is not depleted when used, such as wind or solar power. Fossil fuels and renewable energy both provide energy in the form of electricity, however these different forms come at different costs. Whether those costs be environmentally or financially, both sides have their positives and negatives. We…
