Lithium-ion battery Essays

Batteries have changed a great deal over time. In particular, nickel cadmium batteries and lithium ion batteries are examples of this change. Nickel Cadmium batteries are the older of the two batteries, however they are still used in a wide variety of products. One particular problem with these batteries is that, with extended use, they endure a memory build up, in that they need to be charged and discharged in order for extended usage. This is because, when the battery is not charged up to full

number of electrons in the atom when it is not ionized. (An ion is an atom where the amount of protons and electrons is not equal.) Lithium has 3 protons; therefore it must have 3 electrons when it is not ionized. The protons and neutrons together form the nucleus. Lithium has 3 protons and usually 4 neutrons since its atomic weight is 6.9 according to the periodic table. The atomic weight is 6.9 because most isotopes in natural Lithium (isotopes are defined as atoms with “the same number of protons

Electronic cigarette sales reached $2,875,000,000 in 2015, according to Statistic Brain. This site reports that 2.750,000 individuals use e-cigarettes and 29 percent of people who try vaping quit smoking within a six month period. Although vaping is not considered a smoking cessation method, many smokers now try this activity to see if they like it. Furthermore, some individuals who have never smoked have opted to try vaping. When a person goes to vape, they need a device, and many choose to make

Chuck Jones wrote the article, “A $29 Battery Could Cost Apple Over $10 Billion,” where he talks about how IPhone’s supply would decrease if the new battery becomes the better option for consumers. The IPhone 6, 7, and SE models have the ability to change their batteries at the cost of twenty nine dollars. This is a great possible opportunity to fix issues on the IPhone, by fixing their slowness on the phone and other issues involving the battery. This could be good for the consumers, but it could

Safety is the number one consideration when it comes to jobs like welding. Welding can be very hazardous to a welder if he or she is not wearing the proper safety gear or taking the proper safety procedures. When welding a number of things could go wrong from explosions and gases and fumes to electrical shocks, burns and more. This paper will describe welding hazards and procedures that can be taken to avoid them. One of the main safety hazards of welding is fumes and gases. Many processes such

The problem is that the world is a very massive place, where we need a lot of energy to fulfil the basic needs of our lives. Through the years we have been presented with several different alternative energy source options, as the energy sources like fossil fuels works against the environment. Nuclear fission is one of the alternative energy sources which is considered to be the future energy source of the world, but just like any other things nuclear fission has several disadvantages and advantages

Tetrahedral distortion is defined as the change in both the distance of bond and angle of bond are present. The degree of distortion with respect to the beta phase can be related to the tetrahedral tilt angle and the intertetrahedral bridging angle. While for tetrahedral tilting, there is only change in the angle of the bond and no change in bond distance. When there is an increase in temperature, the Fe-O-P bridging angles increases and the tetrahedral tilt angles decreases. As the temperature increases

Mariel Beauroyre 9-B A chemical bond is form with the joining of two or more atoms (when two atoms are joined they form molecules and compounds.) Which are being held together by the attraction (force attraction) of atoms through sharing as well as exchanging electrons. Chemical bonds are found in molecules, crystals, or in solid metals. They also organized the atoms in order structures. But why are they important you may ask? They’re important because every material or substance in the world

Due to water’s polar structure, ions in some compounds attract and form bonds with water molecules, forming hydrates. A hydrate is a salt that has water molecules trapped within its crystals. Every hydrate has a certain number of water molecules weakly bonded to the salt as follows: salt • number of water molecules Anhydrous salts are salts that can form hydrates but which have had all the water driven off, usually by heat. By heating the Copper (II) sulphate hydrate until its color changes from

Xenon is element number 54 and it has an atomic mass of 131.29. There are 77 neutrons and 54 protons in Xenon nucleus. The element symbol for Xenon is Ce and Xenon is part of the Noble Gas Family. The founders of Xenon are Sir William Ramsey and Morris M. Travers from London. The Chemists found Xenon in 1898 on The University of London. Finally, both of the British Chemists found other elements part of the Noble Gas Family. “The British Chemists used a powerful machine that cooled and

Answer # 1: Ionic Bonds: A molecule or an atom that losses or gains electrons are called ions. Atoms from cations, when they lose electrons or anions when they gain electrons. Ionic bond is basically a strong bond formed when oppositely charged ions are attracting to each other. Ionic bonds are non-directional bonds might be attracted to one another in any direction. For example: Sodium atomic radius = 0.192 nm Chlorine atomic radius = 0.099 nm Sodium ionic radius = 0.095 nm Chlorine

The purpose of this lab was to be able to use physical characteristics to determine the identity of an unknown compound. The data from this experiment classified aluminum as metallic; ascorbic acid, paraffin, palmitic acid, sucrose, graphite, and water as molecular; sodium chloride as ionic. In order to determine this, 3 tests were conducted. The first test was to test the conductivity of each substance at room temperature. In this test, only graphite and aluminum conducted. This shows that these

First, two grams on an unknown white compound were given. The possible compounds the known could be were CaCO3, KNO3, NH4Cl, CaCl2, K2SO4, (NH4)2SO2, Ca(NO3)2, NaC2H2O2, K2CO3, MgCl2, Na2CO3, 0.1 M AgNO3, MgSO4, NaCl, 0.2 M BaCl2, KCl, NaSO4, Mg(s), HCl, HNO3, NaOH, HC2H3O2, H2SO4, and KOH. The solubility test required using a scale to measure .575 of our unknown white compound. The unknown compound was measured in a 100 mL beaker. Next, a 100 mL graduated cylinder was used to measure 60 mL of distilled

NaCl is sodium chloride,and SCl_2 is a compound known as sulfur dichloride. The compound NaCl or sodium chloride is or would be classified as an ionic bond. Then the compound known as SCl_2 or Sodium dichloride would be classified as yet again another Ionic bond. The two types of covalent bonds are regular covalent bonds which the elements atom is partially full but not all the way to the point were you can share electrons. Carbon forms covalent bonds. Covalent bonds are strong due to the hybrid

consistent orange flame. Potassium omitted purple light, magnesium showed no change in color, and calcium produced a red light. When heated, due to the excited movement of the electrons specifically in the metal ions within the compound, flame colors are produced (2). The structure of a sodium ion in its ground state is 1s22s22p6 (6). When heat is applied, its electrons then gain energy giving them the ability to jump into empty orbitals at high levels (2). Once the electrons reach a higher level however

KCL is an ionic bond. This is because potassium (K) has a charge of +1 and chorine having a charge of -1. K gives one electron to chlorine, this makes it so both of them have a full valence shell. GeCl4 is a covalent bond, due to it being hard to separate its 4 valence electrons so Germanium shares its 4 valance electrons to Chlorine therefore making 5 full outer valence shells. BrCl is a covalent bond. Chlorine has a high electronegativity then bromine, and is a dipole-dipole which indicates to

dissolves into the solid because it causes the barium carbonate or calcium carbonate to dissociate, which results in barium or calcium ions in the water, preparing the ion for the addition of ammonium hydroxide and potassium chromate. If the acetic acid fails to fully dissolve in the solid, it will prevent the barium or calcium from reacting with the chromate ion in the following step thus deeming the results in a false positive. In other words, the solution would appear as if barium or calcium was

Calcium chloride is commonly used as the main ingredient in road dust control products because it has the ability to hold on to moisture for a longer period of time. Therefore, this keeps the dust from becoming airborne. Since the dust remains settled on the ground this creates a smooth surface that is easy to drive on. One of the reasons why calcium chloride is so effective is due to how it is handled prior to use. If the chemical substance is stored incorrectly this can ruin your roads and create

of the chloride ion. (This precipitate indicated a reaction and the silver nitrate test states that if a reaction occurs, and a solid is formed than the chloride ion must be present.) But this test also gives positive results for the sulfate ion, so we also had to perform the barium chloride test. 1 mL of our unknown compound was mixed with 1 mL of 6 M HCl and 1 mL of BaCl2 solution. There was no formation of a precipitate whatsoever, indicating that there was no sulfate ion present. (The absence
