    Nearly every battery in a phone, laptop or electric car is lithium based. The element lithium is a difficult substance to harvest. It must be evaporated from brine which is found in salt lakes. This brine is pumped from underground to the surface then allowed to evaporate in large pans before being separated by electrolysis. From there the lithium metal oxide is taken to a factory where it is made into battery cells [6]. 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 prismatic cell, are stacked, the electrodes connected, and an electrode stack inserted. Then the sub assembly is put together. This includes connections, terminals, vents and safety devices. From there the cell is sealed using a…

    The components of the lithium ion batteries include a positive electrode made of metal oxide, negative electrode made of carbon (graphite), a separator made of a micro-porous polymer, and an organic electrolyte (ether) that is made up of dissolved ions of lithium. During recharge, the lithium ions travel from the positive metal oxide to the negatively charged graphite electrode. The reverse flow occurs during discharge (when the battery is in use) (Carnegie, 40; Divya and Østergaard, 513).…

    By having the new technology in fire alarms provides with a early warning and faster responds time. In the past smoke detector were equipment with batteries that had to be replaces twice a year. This was often neglected resulting in death injury and property damage. With the long life batteries this enhanced of the home owners. Heat detectors are the oldest type of automatic fire detection device. The heating detector is another way to solve the problems of deaths due to fires. Heat detectors…

    Is the environmental impact of lithium ion batteries worth the gain that we recieve from them as energy storage devices. This issue includes the impacts of mining, producing and dumping of the product which includes the mining of metals like nickel, cobalt and lithium. Batteries are often dumped in landfills and not recycled, recycling batteries can greatly reduce the environmental impact in most cases. The mining of lithium has a negative impact on the environment it is found in and so if there…

    While Tesla designs, manufactures, sells and services their own vehicles they recognize that due to the company being one smallest auto manufacturers in the world that they needed strategic partnerships to stay in business. The first partnership that Tesla entered into was being with Daimler in 2010. For a 10% stake in Tesla, Daimler got Tesla’s lithium-ion battery packs into 1,000 of its electric smart cars. With the infusion of capital from Daimler, Tesla could continue with their…

    Safety in the Dreamliner: Containing Battery Fires Designing a long-haul, twin-engine airliner that impressed both operator and passenger was the goal of Boeing when they launched the 7E7 program in 2003. Sweptback wings, higher-humidity in cabins, composite fuselage, ultra-high thrust engines and a simulated sky interior were just a few improvements since air transportation of an earlier generation (“Boeing 787 Dreamliner long-range,” n.d.). The aircraft plagued by launch delays, Boeing’s 787…

    seen in the emerging technology sector, with new technologies to replace the old. For example, phone manufacturers like Apple and Samsung release newer versions of smartphones every year, not only creating new demand but as a result, make older phone models obsolete. This can be seen as a benefit to the economy by creating new demand and increasing consumer spending. However there are negative effects to this, new technologies often enter the market with little to no supervision. This can cause…

    The car was cheap and had the great quality better than its earlier cars before. It obliterated all competition with its competitors because how inexpensive it was to own one. “It cost 850 dollars in 1908 when it first came out then the price decreased as time went on too making it a low price of 300 dollars in 1925”(history.com staff 2). The starter of the car also changed instead of hand cranking it to start; this car had the battery powered starter to power the vehicle. It had a sliding gear…
