Anode

Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the positively charged electrode. Graphite is usually used in electrolysis. This electrode does not interfere with the reactions occurring at the surface of the of the electrode. Its main purpose is work as a…

In a battery, electrons and ions flow from the anode to the electrolyte in an oxidization reaction. Those electrons are then accepted by the cathode, creating a circuit where electrons flow from anode to cathode. The electrolyte facilitates contact between the chemicals in both electrodes. This contact ends up converting chemical energy into electrical energy.…

Nearly most of camera lens is made of glass. Now some manufacturers adopt sapphire to make camera lens. Compared with glass, the biggest advantage of sapphire is its hardness. It's nearly twice as hard as standard glass, and nearly as hard as diamond. The extremely high hardness means it is nearly impossible to scratch it. Sapphire also have a compressive strength of 2,000MP, about ten times that of stainless steel, which means it is extremely strong. Those attributes can guarantee the optics of…

At the factory the anode and cathode materials are separated for production before being added to the electrode. The anode materials are a form of carbon, whereas the cathode materials are made of the lithium metal oxide. Each of the materials are then separately combined into a semi liquid mixture, and then spread in layers onto the electrode foil. From this coating machine, the coated foils are sent into an oven. Then these cathode and anode foils are assembled. Both anodes and cathodes, for a…

with a vacuum tube with a wire component at one end forming the cathode (-), and a heavy copper target at the other end forming the anode (+). When Röntgen applied a high voltage to the electrodes, the electrons formed at the cathode were attracted to anode and striked with a high amount of energy. Roentgen found that very penetrating radiations were produced from the anode, which he called x-rays. In an X-ray machine, a stream of highly charged electrons is made to strike a metal target. This…

30B with a cation exchange capacity (CEC) of 90 meq/100 g was procured from M/s Southern clay Products. Conc.H2SO4 (98% pure) used as sulfonating agent was supplied by Merck lab grade. The catalysts, Pt black for the cathode and Pt/Ru black for the anode, were purchased from Johnson-Matthey, USA. Nafion® 5 wt-% binder solution from E.I. DuPont Company was used for membrane electrode assembly. Nafion® 117 membrane, from E.I. DuPont Company was chosen as the commercial sample to compare…

How does a variation in the concentration of metal ions of the cathode in a Zinc-Copper electrochemical cell affect the electrical potential? Introduction: In a highly technological and quickly developing society, it is imperative to innovation that basic components are understood and explored to further expansion and advancement. In order to understand how everyday necessities such as cars, computers, and cell phones are constantly powered, it must first be understood what is in a battery as…

BATTERY BANK THE CHEMISTRY According to (Wikipedia, 2016), the deep-cycle battery is a type of lead-acid battery designed to be regularly deeply discharged using the majority of its capacity (45% - 75% depending on manufacturing and construction). These batteries are able to be cycled down to 20% charge, but the best cost vs lifespan method is to keep the average cycle at approximately 45% discharge. There is an indirect correlation between the number of charge and discharge cycles the battery…

an apparatus is added in order to allow the free flow of electrons. Oxidation occurs at the anode and reduction at the cathode. A zinc electrode is placed in zinc sulphate (ZnSO₄) and a copper electrode is placed in copper sulphate (CuSO₄). These are half cells which are designed to handle oxidation half-cell and reduction half-cell reaction separately. The oxidation of zinc happens at the half-cell anode: Zn (s) → Zn2++2e- The oxidation of zinc causes the zinc electrode to dissolve to produce…

called electroplating is used to coat one metal with another metal. In this case, zinc will be electroplated onto the negative electrode, the cathode, when the ionic zinc chloride is discharged through reduction processes. At the positive electrode—the anode—chlorine gas will be…
