The Li-ion battery has quickly become the battery of choice for a number of portable electronic and mobile applications, surpassing the rechargeable batteries using aqueous electrolytes that were previously used (e.g., NiMH, Ni-Cd, Pb-acid).
Identify a type of device or commercial product that is currently powered by a Li-ion battery, but may have been powered by an aqueous rechargeable battery in the previous versions. The product need not be manufactured by the same company. As an example where the device is an electric car, Tesla uses Li-ion batteries in their cars, while the first Toyota Prius used a NiMH battery. Address all the points below.
a) What are the specifications of the Li-ion battery being used (e.g., energy/capacity/voltage,
dimensions, weight/volume) and some relevant performance characteristics (e.g., time it can be
used before needing to be recharged)?
b) Repeat part a), but for the aqueous battery used in the legacy version of the device.
c) Provide an explanation for why these particular aqueous batteries were initially chosen for the
application (if not specified, include your own opinions, and justify them).
d) Explain what kind of advantages and benefits have been enabled by the implementation of Li ion batteries in the device. Describe disadvantages, if applicable.
e) Please provide links or full citations to all sources used.[supanova_question]
Life-Cycle Assessment of Natural Gas
Engineering Assignment Help Please refer to the instructions attached along with two papers I found very useful and can build the skeleton of the project proposal. You may identify other papers as you like.
Note the following:
1) No LCA of natural gas and nuclear power plants done in Saudi Arabia. This should be highlighted in the Method section part.
2) GaBi Software will be used to support our project. This should be included somewhere in the project proposal, either under literature review or methods. Please look up GaBi in the internet to get a better understanding of what it is.[supanova_question]

We’re supposed to create a timesheet. Our idea is that the employee has several tasks per day. In order for him to move from task to another he should finish the first task and tick it in the timesheet. else he won’t be able to move from task to another by doing so the supervisor and the client can keep track of what the employee have accomplished and how long did it take him to accomplish a certain task. If the employee did not finish a certain task in the specific time he gets an extension to complete the task in order for him to move to the next task. Also if the employee did not accomplish anything during the day he gets a warranting from his supervisor.[supanova_question]
