But, still, only 80mah a day . So 750mah scaled up to iPhone battery size. So abut 1/5 of the average daily power requirement for an iPhone. Even at that rate you’d need to use a supecapacitor to even out the load profile.
OTOH, in terms overall energy, it would be about the same as about a 50 litre lithium ion so it is rediculously dense, just low output

- swores 2y agoFYI, your comment made me look up PixelQi and Wikipedia says that conpany died almost a decade ago (although 2015 feels to me like much, much less than a decade ago): > "By 2015, PixelQi's team and offices were unreachable, and the company is presumed defunct.[3] The intellectual property is now owned by the original investor of Pixel Qi, while the right to manufacture Pixel Qi technology contractually rests with Tripuso Display Solutions.[4][5]" https://en.m.wikipedia.org/wiki/Pixel_Qi https://en.m.wikipedia.org/wiki/Pixel_Qi
