Alternative Electrode Materials: Batteries Essay

The use of electricity may go back further known as the Parthian Battery. The battery dates back to the Parthian empire and is believed to be 2,000 years old. However, the battery is known from its creator Alessandro Volta (a chemist and physicist and pioneer of electrical science). Volta is known for voltaic electricity (same as volts) and for many other things. The basic property of a battery is that two objects work as electrodes, causing an electrochemical reaction which generates voltage. 5]

Cathode : ½ O2+H2O+2e → 2OH- Overall: Zn+½O2 → ZnO Zinc/air battery not only provides a high energy density, but also has many advantages. Based on the electrochemical principle, it is clear that it produces electrochemical energy by using oxygen, which can be directly obtained from the atmosphere rather than from the system itself, which makes the miniaturization of micro-battery possible. The oxygen diffuses into the cathode during discharge and reacts with the electrolyte

LITHIUM-ION BATTERIES Abstract Technology is striving to keep up with today's society. We continuously require smaller, lighter and more autonomous equipment. The rechargeable lithium ion battery is the most important factor in determining the rate of development of modern day consumer electronics. Perhaps not surprisingly the transport of lithium ions (Li+) remains the preferred technology to achieve this. As a result and for the purpose of this review, only the Li-ion battery (rather than

Metal-air batteries have been intensively explored as an alternative future energy storage and conversion systems owing to their intrinsically high energy and power densities, the relatively mature research on air electrode, and cost effective composition of non-noble fuel electrode, as well as in response to the high energy demand for portable devices and electric vehicles even stationary power plants [1–5]. Of late, research into the metal-air techniques has been focused on Zn-air (~1,000 Wh kg-1)

In order to identify one major issue in smart grids design, we propose a thought experiment: what if we could built a smart power supply system from scratch? Would we rely on existing concepts, or we would adopt a radically different approach? Imagine this new, technologically advanced, country called Newlandia. Newlandia may or may not be particularly rich with energy generating natural resources and has never had a power supply system. However, Newlandia enjoys major benefits: it is free from political

While Lithium based batteries have allowed electronic products to become more portable, current applications of lithium based batteries are starting to show the limitations of the current technology. These limitations include aspects such as energy density, charge rate, and the usable lifetime of the battery. Furthermore, over the past decade safety concerns of lithium ion batteries have become more and more apparent in both industrial and consumer uses of lithium based batteries. The push towards

technologies which require electrical energy. The electrical energy is used everywhere, from heating homes to manufacturing. The energy resources are divided into two types: alternative and traditional energy resources. The global energy challenge is

Robotics Fig 1:The Shadow of Robotics Hand What is Robotics?? Robotics is the branch of technology that contributes the design, construction, operation, and application of robots as well as computer systems for their control, sensory feedback, and information processing. These technologies deal with automated machines that can take the place of humans in dangerous environments and resembles as humans in appearance, behavior, and cognition. Many of today 's robots are inspired by nature of contributing

are cleaner than gas-powered car, but is that true. I asked myself Are Electric Cars Better Than Gas Cars? Then I sat down are started to think about the two types of cars. How are electric and gas cars made? How are the resources for the electric batteries gathered and how is oil for gas cars gathered? How much energy do electric and gas cars need to run, what does it cost? How is the energy for the electric and gas car made? Lastly, Are the energy sources for the electric and gas car environmentally
