But context helps...
"Nickel-zinc alkaline is seen as a less fire-prone alternative to lithium-ion cells, which have been banned for some US military applications, according to NRL."
So they now have a battery that works with a few hundred cycles with density close to that of Li-Ion that won't explode. It may not replace Li-ion in your vape stick but still sounds like a win for the emergency lights in the armory of a battleship (for example).
- user5994461 9y agoI'd expect a battleship to stay in operations for a very long time without spare part and replacements available. The battery will long be dead by the time they'll need it.
- Jtsummers 9y agoWouldn't that depend on how often the batteries were actually needed? That is, if the system is primarily externally powered and only alternately powered by a battery (under various conditions), it shouldn't exhaust those charges too rapidly. Or like some systems I worked on, the batteries were strictly for things like maintaining a clock and some volatile memory, very slow discharge rates, when the aircraft were totally shutdown.
- msl 9y agoWhy? What will kill it before then? What kind of a battery would have a long enough shelf life?

- Tloewald 9y agoAn aircraft carrier needs resupply with avgas every three days when operating up-tempo. Warships use up resources like crazy, they're not going off on five year missions like Star Trek.
