Megan Treacy on Treehugger<\/strong><\/em> reports<\/a> on a new twist – low-power batteries that self-destruct<\/em> after usage:<\/p>\n

Having a battery that is able to break down at the end of the life gets us one step closer to a device that could basically disappear when its job is done.<\/p>\n

Researchers at Iowa State University<\/a> have developed a battery that quickly destructs when dropped in water. The lithium ion battery can produce 2.5 volts and can power a desktop calculator for about 15 minutes. When submerged in water, it dissipates in just 30 minutes. The university says this is the first so-called “transient” battery to have the power, stability and shelf life needed for practical use.<\/p>\n

\u201cUnlike conventional electronics that are designed to last for extensive periods of time, a key and unique attribute of transient electronics is to operate over a typically short and well-defined period, and undergo fast and, ideally, complete self-deconstruction and vanish when transiency is triggered,\u201d the scientists wrote in their paper just published in theJournal of Polymer Science, Part B: Polymer Physics.<\/a><\/p><\/blockquote>\n

“Vanish”? I could understand the blogger saying that, but she’s quoting the paper. Megan explains further:<\/p>\n

When submerged, the casing swells and breaks apart the electrodes, then dissolves away. The researchers stressed that there are nanoparticles that don’t completely disappear, but they do disperse.<\/p><\/blockquote>\n

It’s an interesting thought. I’m trying to see how to implement it safely in a health environment, and really the only process close to fail-safe would be for it to dissolve once the energy it generates is exhausted. You can’t do it on command, because that makes you vulnerable to malicious forces; basing it on environmental factors in a body seems impractical, since the environment, at least this level, would seem to me to be relatively static – but I don’t really have any relevant expertise.<\/p>\n
