Theodore Grey Biography

In this world there are people that have done great things Dane gray one of them. Dane Gray was born into a poor family who every Christmas only got two presents because they couldn't afford anymore. As a young adult Dane Gray had to learn to fend for himself because his parents both worked 50 hour weeks and he had to take care of his little brother. As Dane Gray got older he learned a very important lesson that you don't get anything that you don't earn. He is taking this saying and has applied it to his life. In the beginning Dane gray found a girl that he later on Married named Cindy belt. He fell in love with her and decided to have three children Drew, Jaclyn ,and Matthew. Dane Gray didn't go to college straight out of high school because he believed that he needed to work and provide for his family as he worked he found that he needed a education. So he went to ITT and learned how to be a electrician. He got hired on to a place called Alcan and work there for 15 years.

David A. Kirsch examines the manufacture of storage batteries for the electric vehicle, which was manufactured by various companies. As these companies rushed towards the manufacturing process of the vehicle, the development of its storage batteries was one of major troubles in the initial stages of the production process. These companies neglected improvements of the storage battery by failure to transform any of their previously renowned characteristics. This was despite expectations by early electric vehicle enthusiasts of a revolutionary discovery in energy storage technology. The expectations were based on the fact that engineers in the second half of the 19th Century had experienced several technological revolutions. Regardless of incremental technological changes that have relatively enhanced the capability of the ordinary electric vehicle, the expectations were never fulfilled, especially those for better storage battery. Even though there was significant progress in technologies used to manufacture the electric vehicle system, none of these technologies were able to meet the expectations.

As explained by IDTech Ex report that the flexible electronics market will reach over $76 billion by 2023[1],while the market for flexible, thin, stretchable and bendable batteries will grow to become about $471 million industry by 2026[2]. Additionally, the product is considered the most promising energy storage device with low carbon dioxide emission. The energy density of the lithium ion battery range between 120-170 Wh Kg-1 and 250-380 Wh l-1 more higher than Ni-Cd and Lead-acid[3]. LIB has three major electronically active components namely anode, electrolyte, and cathode. The anode is the negative electrode that releases electrons into an external circuit during a discharge process that involves the oxidation of chemical reactions. On the other hand, the cathode is the positive electrode that is reduced during a reaction. Notably, the lithium ions are stored within the cathode after a cell is discharged. Both cathode and anode stores energy while on charge, and releases it on discharge[4]. Cathode materials have relatively high electrochemical potentials while anode materials have low potentials. This design approach helps maximize the battery’s output voltage. The final active component of the LIB is the electrolyte. It is a mixture of a set of organic solvents containing disassociated lithium salts that enables Li+ transportation between the anode and the cathode. Besides, other complementary components, such as current collectors attached to the

This chapter talks mainly about the importance of the periodic table and discusses some of the stories behind some unique and important elements, along with interesting scientific discoveries. Chapter 1 really intrigued me, and I wasn’t expecting that. Even after I read the back of the book summary, I still reluctantly started reading. However, I don’t regret it now because this book is pretty fascinating.

Chemistry is, by definition, the science of matter; yet I used to simply perceive a board when I looked at one. Desks were chopped wood and cars a result of technology. Mundane objects were enclosed in a secure box. Slowly, though, a veil lifted, one I was unaware of possessing, and the world came into focus for

My first chemistry experiment was in 5th grade when my older brother recruited me as his “little helper” for his science project. I was in charge of heating film canisters pre-filled with an alcohol and water mixture to allow vapor to build inside. I also measured how long the canister stayed in the air after the vapor detonated from a spark. The longer air time translated into a more powerful explosion. I was surprised that the data showed that putting more alcohol into the mixture did not make a more powerful explosion.

In particular, for the design of the battery, we chose to investigate the construction of the battery cells, battery module, and battery safety. In regards to the performance enabled by this battery, we investigated the different battery packages available, in terms of energy capacity, and compared their performance to a gasoline-powered car through the quantity of MPGe – mile per gallon equivalent. Last, we delve into the maintenance and owner operation of the Tesla Motors automobile battery – comparing the

Mendeleev’s most famous discovery occurred when he was researching and writing his textbook in the 1860’s, this discovery lead to his most famous achievement which he presented to the Russian Chemical Society in 1869. “Mendeleev realised that the physical and chemical properties of elements were related to their atomic mass in a 'periodic ' way, and

Global warming by carbon dioxide and air pollution is getting serious these days, as a result that led to increased attention for the idea of Electric Vehicle (EV). The idea of an EV has been around for almost 200 years. Thomas Davenport built the first EV in 1834. Until a few decades ago, batteries seemed to be the only device capable of storing the energy in a safe manner. Unfortunately, batteries are still not able to store the amount of energy needed to fulfill the needs of an electric vehicle completely. They also have a low energy to weight ratio and problems with the recharging of the battery are not completely solved [1].

The scope of this paper is to explain the reaction that takes place when Mentos are dropped into Diet Coke. This experiment is used frequently because of what happens when the candy meets the soda. A geyser is formed that shoots out of the bottle that resembles a volcanic eruption. Due to the similarity, it is also used for volcano projects. Depending on the alterations to the Mentos and/or Diet Coke, the geyser can either go much higher or much lower than normal.

Energy is the lifeblood of modern society, but the major energy supplies are fossil-fuel generation, which leads to air-pollution and environmental issues. Then, there is an increasing need to develop renewable energy to balance the demand and supply. Electric vehicles and hybrid electric vehicles will be the effective method to decrease fossil-fuel usage and rechargeable batteries are one of the main strategies to power these vehicles.

Global warming and the end of fossil fuels looming conspire to present the greatest threat to today's world. A realistic solution to curb the use of fossil fuels is the use of clean energy sources. Transportation accounts for 30% of CO2 emissions, it follows then that the use of batteries to power such fields would be a great benefit to the planet. Already used in consumer electronics such as laptops and mobile phones, the rechargeable lithium ion battery offers the highest energy storage per unit weight and volume (Figure 2) and therefore the most appealing for use in applications such as electric vehicles48.

Tesla’s Gigafactory, which opened in June 2014, produces lithium-ion batteries. “The factory’s planned annual battery production capacity is 35 gigawatt-hours (GWh), with one GWh being the equivalent of generating (or consuming) 1 billion watts for one hour.” Presently, products and services utilizing lithium-ion batteries, maintains 16.8% segmentation for

Lithium ion batteries were introduced commercially during the early 1990’s as the desire for smaller and more lightweight rechargeable batteries grew with the increased demand for the improvement of portable electronic devices (Yoshino, 2012). Prior to this there were commercially available rechargeable batteries already on the market, predominately in the form of lead-acid (PbA), Nickel-Cadmium (NiC) and Nickel Metal-hydride (NiMH) batteries. The development of the Lithium ion (Li-ion) battery began due to the knowledge of lithium’s low redox reaction rate and high energy to weight ratio (Wu, 2015), which, it was believed would make Li-ion batteries a good option for introducing smaller, more energy rich batteries to the growing market.

Since the specific energy of a battery is determined by the product of the operating voltage and specific capacity, in order to meet the demanded characteristic of higher specific energy; higher operating voltage, and higher specific capacity need to be achieved. The higher operating voltage can be reached by finding cathodes and anodes such that their average difference of chemical potential is as large as possible while the safety is assured. Conventional cathode and anode materials used in LIB cells could only have a maximum operating voltage of about 4V per cell which needs to be higher if one wants to avoid using numerous LIB cells in series and parallel to meet the high voltage need of about 400 volts for electric cars for example. Similarity, the demanded characteristic of high specific capacity is reached if more efficient and chemically suitable materials other than LiCoO2 and graphite are used in a LIB cell.
