their technology and product innovation as a result of years of research. It all started in 1970 when Geoffrey Ballard‚ Keith Prater and Paul Howard agreed to develop a rechargeable and lightweight lithium battery. Although the company’s main product line was the batters‚ the three partners had a vision to produce the rechargeable lithium type. To what extent should spin-off technologies be transformed into stand-alone products? Spin-off technologies should only stand alone in circumstances where

All procedures were followed according to the lab manual (experiment 10 – Electrochemistry Laboratory). Data and Observations Part A: Grams of FeSO4 used: 0.759 Voltage during voltmeter and battery check: 9.23V Table 1. Electrochemical Cells Data Part B: Table 2. Lead-Acid Battery Results and Calculations In order to make 5ml of 1M FeSO4(aq) (molar mass = 151.92)‚ we calculated the needed grams according to c= n/V; 1 = n/(0.005)‚ n = 0.005. Since n = m/M‚ 0.05X151.92 = 0

Commercial Cells Galvanic Cell A Galvanic cell is also known as a Voltaic cell. It was named after Luigi Galvani and Alessandro Volta. A galvanic cell is capable of producing an electric current from a redox reaction that occurs within it and consists of two half cells. Each half cell consists of an electrode and electrolyte and a salt bridge. In a galvanic cell one metal can undergo reduction and the other oxidation. A typical galvanic cell is based on the spontaneous redox reaction: Net Ionic

Study The researcher‚ as one of the consumers of the electricity‚ also experiences the power crisis. Due to different factors that results to sudden brownouts especially those in the province‚ the researcher came up with the study entitled “Potato Battery”. Two new sources are fruits and vegetables. These are organic and can easily be bought at farms and markets. One of these is the use of potato but not all fruits and vegetables are usable. Potato had been considered due to it’s high content of
