Was discussing with my team earlier on today the progress made in battery technology and got around to discussing capacitors and if they could replace batteries or offer a better means as a storage unit, and why they haven’t really gone mainstream. The ideal super capacitor that would serve the consumer electric market would need to be small, lightweight, charge really fast (5 minutes fast) and discharge slowly (48+ Hrs) and best thing no chemical change or formation of memory. Why isn’t there a phone manufacturer that uses it, or power bank that uses it. What are its potential drawbacks and opportunities. Let’s beat ambaka on this one.
mngebeat huyo Ambaka na hiyo team yako …even hadi kwa mkia …ju hapa na hizo capacitor chemical umetaja, ile umeachieve ni kujiongelesha
Smh!!! How did the interview go? @vnv kuja changia huu mswada, I like how you think
kesho. written
Orals? Went well?
I am fascinated by batterytechnology though my knowledge is very limited in that area. Can’t wait for that phone battery that charges from 0 to 100% in under 5 minutes
Starts with written …then Orals for the successful
ofcourse at a much later date
Is it in the pipeline? What company and tech behind it?
Nakumbuka how my ka amplifier back then kalilipuka hio capacitor ata kwa dawa battery kama hio siwezi

Design n patent it uone u billionaire
There is girl who designed a charger that can charge a phone in matter of seconds Google’s bought the tech and that was the last time I had of it.
I remember her story, think she used titanium oxide to increase the energy density. Also would use graphene instead of copper as it is orders of magnitude lighter and has x100 better conductivity, test for efficiency and well designed packaging. I am sure its commercial use potential is huge
Know what, I just might give it a serious thought
Capacitors have ratings, surpass it and you’ll blow it
The achiles heel for todays electronic devices is battery life. We have bigger screens, more pixels, 8 core processors but the battery life!!! Is it viable to develop a battery and go the Safari battery (can’t compete with phone makers) way or create a really cool power bank?
On the speed of charging: Internal resistance of the battery won’t allow you to drive a high current without blowing it due to heating.
Of Capacitors as power banks: You need a very large area, plus a capacitor can only store half of the energy used to charge it.
On the battery currently as they are yes I agree. On charge storage of capacitors there is a way around that to increase its energy density and they don’t need a large surface area necessarily
The reason super capacitors have not gone mainstream is because of their high discharge. May be in a few years if there is a breakthrough in graphene then it will be possible to make longer lasting super capacitors.
Capacitors hold high voltages but discharge like mahfuckers. That’s how they were meant to be and not to replace batteries. The basis of this is the materials used ofcourse. Unless you wanna make a new electronic component I don’t see the point or possibility of such super duper caps.
