New hydrogen cellphone battery can power an iPhone for a week (inhabitat.com) 9 points by JayInt 10y ago ↗ HN
[–] rem7 10y ago ↗ Also I assume the recharge is pretty much instantaneous? Just re-fill it with hydrogen and you get another 7 days... That'd be pretty sweet
[–] yakult 10y ago ↗ Two problems I can see: 1. You'd need a hydrogen source. 2. Exactly how much vapor does it release? Water vapor next to sensitive electronics, in your pocket, can be very bad. [–] amaterasu 10y ago ↗ Not to mention hydrogen density/atomic size causes substantial problems for storage and transport. [–] jgamman 10y ago ↗ but, it would seem, not in this case. iPhone. 1 week. Pain point solved.

[–] robgibbons 10y ago ↗ Heat production and water vapor are not typically desirable properties for smartphone batteries.
[–] kmcb 10y ago ↗ This looks useful for military/industrial applications. It doesn't look practical for wide-spread consumer applications, any time soon.
