Persuasive essay (Lithium based batteries>Nickel based batteries) [33]
The assignment is to be persuasive, right? So, who exactly are you trying to persuade? Who is your target audience? Your paragraph at the moment might greatly interest someone who is very much into engineering batteries, I suppose. Otherwise, it's a bit dull. I mean, really:
"Though both nickel based batteries and lithium based batteries supply a sufficient amount of electrical power for a variety of electrical devices, the advantages of lithium based technology greatly outweigh that of nickel based cells in terms of capacity, energy density, cycle amount, internal resistance and effective discharge rates"
This may be true. But I am not feeling energized (pardon the pun) about the issue. Now that I think about it, what exactly are you trying to persuade me of? That lithium based technology is better? But I assume that there really isn't much debate over that. Surely "capacity, energy density, cycle amount, internal resistance and effective discharge rates""are all empirical measures? This is more informative than persuasive, then. Or are you trying to persuade me to only buy lithium batteries? But if nickle batteries supply a "sufficient amount of electrical power" then none of your reasons is persuasive, if nickle batteries are 10 times cheaper than lithium ones (they may not be, but how would I know, as you haven't touched on this aspect of the topic?)
And this is why, though your paragraph is well-written and well-informed, it might garner a low mark from your teacher. "By showing hard data and in-depth information on a variety of battery chemistries, one will most likely be able to determine the immense advantage lithium based batteries have over nickel based batteries." But you won't be able to persuade me of anything. You can inform me that lithium batteries are better. If there is any debate about that, you can convince me to agree with you to avoid having to listen to any more on the subject, which is about as fascinating to most people as watching paint dry. But you haven't given your audience a reason to care about a topic, or explained why the topic is important, or why you think the audience might need to change its mind about it. Indeed, it seems likely that most people you might be writing this for probably don't
have an opinion on the topic at all, and so don't need to be persuaded to change their minds about anything.
So, either pick a different topic, or find a way to make this one interesting. And either way, make sure that you are arguing a point that at least some of your audience might vehemently disagree with. Persuasion implies resistance. That is, you don't need to persuade people who already agree with you. You need to persuade people who don't.
Good luck.
