Hello everybody, and welcome to my TALON Talk. I hope you enjoy my presentation and learn something new. Please click the link down below to view my PowerPoint. I strongly suggest that you download the presentation because it does not work well in the browser.
Hi Noah, nice Talon Talk. Your presentation had a lot of information that was still relevant to the topic. The slides were well made with lots of useful diagrams and information. One question I have is how does your personal experience with different brand batteries compare to your research?
I really enjoyed your TALON Talk, Noah! You did a great job of really going in-depth with your topic, beyond just what your question demanded. You did a great job of explaining the concepts in your presentation using a consistently clear voice. The visual aids you included in your presentation made understanding your points easier as well. A critique is that I think you could have spent more time comparing the batteries of different companies, although the background information and information on primary & secondary batteries were interesting as well.
A question I have for you is: Does the efficiency of a rechargeable battery decrease as you continue to use it after recharging the battery?
Hi Noah,
Great job on the Talon Talk! You spoke with clarity and explained each subject very well. You added many images and diagrams which only added to the clarity of your words and made everything easy to understand. I found that the background’s style changed slightly back and forth.
What factors would lead to the most rapid degradation of a battery’s health?
Hi Noah, really enjoyed the talon talk.
You had a clear voice and carefully chosen words which made it easy to understand. Also having images and diagrams on every slide enhanced the visual appeal as well as just made the topic more interesting.
One thing I found was that the background was a little inconsistent, there were some slides with a nice design and background but some other slides had blank background.
A part I was quite interested in was which causes more battery life drain, the load or the battery quality, for example which would last longer, a modern battery in an outdated device or an outdated battery in a modern device?
Hello Noah. Your presentation was in-depth and very easy to understand. I enjoyed how you inserted relevant images into every page to accompany your script. The diagrams and graphs added a visual iteration of the information your were explaining at the time so it was far easier to recognize the main points. A critique I have for you is that you could have spent more time comparing the battery life of different companies’ batteries. A question I have for you is: is there a battery brand that you would recommend and why?
Great TALON Talk Noah. I appreciated all the diagrams and graphs you included as they made your presentation easy to understand. The diagrams were relevant to their respective slides, adding a visual representation of what you were explaining, and they added visual interest to the presentation.
One critique I have is while you did talk aspects that affect battery life, you did not compare the efficiency of batteries from specific companies. My question for you is what allows rechargeable AA batteries to charge without exploding, and why do you think this has not been implemented in all primary batteries?
I appreciate your perspective and compliments, Mahtab. I will try my best to follow your advice in my next presentation. Back to your question, secondary AA batteries can recharge without exploding because of the elements used within the battery. Elements like lithium, cobalt, and carbon work well in secondary batteries to allow the reversal of the flow of electrons. When primary batteries attempt to reverse the flow of electrons, the chemical reaction doesn’t work efficiently, and hydrogen gas is produced within the cell. The gas builds more and more and the release of the hydrogen causes the explosion. The reason why primary batteries do not use elements like lithium to become rechargeable is because of the cost. It is much more expensive to manufacture batteries with cobalt and lithium as opposed to manganese dioxide and zinc.
Thank you Edward for your compliments and advice. I appreciate all the feedback I can get. As for your question, Energizer and Duracell are the most popular primary battery companies. They are the top brands mostly because they have built a great reputation over decades of battery manufacturing. Duracell and Energizer also have lots of marketing to advertise their batteries.
For secondary batteries, the company LG Chem is the most popular retailer. LG focuses on lithium-ion batteries for large automobile corporations like Stellantis and General Motors. They remain at the top mostly because they have a reliable source of income from major companies.
Hi Noah,
I really liked how your presentation went in-depth into how batteries work. This has been something I’ve always wondered about, but never looked into. Your slides were also simple and easy to understand, and your voice was clear throughout.
One suggestion I have would be to focus more on comparing the batteries of different companies and perhaps coming to a conclusion based on that. My question is related to this: Currently, what is the most widely used battery brand and why (primary and secondary)?
