哈佛的研究离应用还很远很远，只是基础研究。也许因为您说的不合适的地方，金属氢永远也不会成为优良炸药。
但是作为未来高能炸药，金属氢的优点足以让研究者去探索和制备了。
我想说的是，研究金属氢，初衷不是为了他的稳定性，更不是为了制作电池。氢的含能量高是摆在那里的，液态氢也高。获得金属氢就为了活泼性，有了活泼性才好谈下一步。
用作燃料电池的氢，有一个方向是希望将氢与金属结合，能方便的储存和释放，这个方向和氢做成金属态不是一回事，楼主可能是把这两者搞混了。

不能一概而论，在特定的场合，即使能耗大，也是值得的。控制才是决定因素

还真是这样啊，原来氢就是在金属一列，看来本来就有金属性质，只不过平时是气态，谢谢你的帮助。

金属氢不需要氧化剂我不认同，但这是后续引爆的事情。
做炸药，先决条件是活泼性，
同质量下与氧化剂结合能力越强越好。
具备了这种能力，如何引爆是后续的事情。
如果什么也不需要就爆炸，那不是炸自己了。
火箭用的液氢液氧做燃料，不就是看重液氢能量密度大么。
只是液态金属不具备金属锂金属钠的活性，如果能成为金属氢，就能获得梦寐以求的活泼性，就有了瞬间引爆的理论可能。
当然如何制取，如何保存，如何引爆，都需要大量的后续工作。
一句话说，把液态氢变成金属氢，看重的就是不稳定性。
再次吐槽本贴楼主，和美国在军事研究上的投入比，丰田那点投入和知识储备算个毛线啊。 本帖最后由 tangwei989 于 2017-2-7 18:22 编辑

把一块固态氢用495千兆帕斯卡的高压（大约相当于488万个大气压）挤......

金属氢常压下不存在，高压下变金属的非金属多了去了
金属氢如若做炸药也不是靠活波性和易燃，因为不需要氧化剂

适合做太空武器，比如星际迷航里的光子鱼雷

氢本来就是非金属，那来的金属，搞不懂。

好好的丰田，都被无忌上的托毁了……

丰田指导哈佛

金属氢早就有了吧。

Other researchers aren't convinced. It’s far from clear that the shiny material the researchers see is actually hydrogen, says geophysicist Alexander Goncharov of the Carnegie Institution for Science in Washington DC. Goncharov has criticized the Silvera lab’s methods before. He suggests that the shiny material may be alumina (aluminium oxide), which coats the tips of the diamonds in the anvil, and may behave differently under pressure.

Loubeyre and others think that Silvera and Dias are overestimating the pressure that they reached, by relying on an imprecise calibration between turns of the screw and pressure inside the anvil. Eugene Gregoryanz, a physicist at the University of Edinburgh, UK, adds that part of the problem is that the researchers took only a single detailed measurement of their sample at the highest pressure — making it hard to see how pressure shifted during the experiment.

“If they want to be convincing, they have to redo the measurement, really measuring the evolution of pressure,” says Loubeyre. “Then they have to show that, in this pressure range, the alumina is not becoming metallic.”

But Silvera says that he just wanted to get the news out there before making confirmation tests, which, he says, could break their precious specimen. “We wanted to publish this breakthrough event on this sample,” he says. To preserve the material, he and Dias have kept it in the cryostat; the lab has only two cryostats, and the other is in use for other experiments, he says. “Now that the paper has been accepted, we’re going to do further experiments.”

Despite the scepticism, press-release materials issued byScienceand by Harvard University confidently proclaim that metallic hydrogen has been made. “This is the holy grail of high-pressure physics,” Silvera says in Harvard’s press release. “It's the first-ever sample of metallic hydrogen on Earth.”
