Can an expert comment as to why this is too good to be true?
- lutze 13y agoNot an expert, but from what I understand it's a trade off. Super-capacitors hold much less charge than batteries. There was a very interesting article about them on HN last year IIRC.
- zorlem 13y agoMaybe this one: https://news.ycombinator.com/item?id=3723943 https://news.ycombinator.com/item?id=3723943 , but I'm still unclear if OP invention or break-through is for the same technology.
- gizmo686 13y agoIt isn't. Everything described in the article is consistent with graphene supercapacitors, although the article gives no technical details about what she actually did.
- haldujai 13y agoIt is too good to be true. It's not a graphene supercapacitor it's a H::TiO2 with a PANI core based supercapacitor, which is quite difficult to synthesize, especially mass produced. Every reagent required is considerably more expensive than a comparable Li-Ion battery. They also have a significantly lower energy, so while they may be faster to charge and have longer life spans they wouldn't fit in modern phones. http://www.ncu.edu.tw/~ncu7020/Files/Phd_Repord/93/Engineering/jfy/paper.pdf http://www.ncu.edu.tw/~ncu7020/Files/Phd_Repord/93/Engineeri...
