Researchers Report Super-Powered Battery Breakthrough

another random user writes with news that researchers from the University of Illinois at Urbana-Champaign are reporting a breakthrough in battery technology. They say: "With currently available power sources, users have had to choose between power and energy. For applications that need a lot of power, like broadcasting a radio signal over a long distance, capacitors can release energy very quickly but can only store a small amount. For applications that need a lot of energy, like playing a radio for a long time, fuel cells and batteries can hold a lot of energy but release it or recharge slowly. ... The new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale (abstract). The batteries owe their high performance to their internal three-dimensional microstructure. Batteries have two key components: the anode (minus side) and cathode (plus side). Building on a novel fast-charging cathode design by materials science and engineering professor Paul Braun’s group, King and Pikul developed a matching anode and then developed a new way to integrate the two components at the microscale to make a complete battery with superior performance. With so much power, the batteries could enable sensors or radio signals that broadcast 30 times farther, or devices 30 times smaller. The batteries are rechargeable and can charge 1,000 times faster than competing technologies – imagine juicing up a credit-card-thin phone in less than a second. In addition to consumer electronics, medical devices, lasers, sensors and other applications could see leaps forward in technology with such power sources available."

  1. Slashdot is being abused... apk by Anonymous Coward · · Score: -1, Offtopic

    A corrupt slashdot luser has pentrated the moderation system to downmod all my posts while impersonating me.

    Nearly 230++ times that I know of @ this point for all of March/April 2013 so far, & others here have told you to stop - take the hint, lunatic (leave slashdot)...

    Sorry folks - but whoever the nutjob is that's attempting to impersonate me, & upset the rest of you as well, has SERIOUS mental issues, no questions asked! I must've gotten the better of him + seriously "gotten his goat" in doing so in a technical debate & his "geek angst" @ losing to me has him doing the:

    A.) $10,000 challenges, ala (where the imposter actually TRACKED + LISTED the # of times he's done this no less, & where I get the 230 or so times I noted above) -> http://it.slashdot.org/comments.pl?sid=3585795&cid=43285307

    &/or

    B.) Reposting OLD + possibly altered models - (this I haven't checked on as to altering the veracity of the info. being changed) of posts of mine from the past here

    (Albeit massively repeatedly thru all threads on /. this March/April 2013 nearly in its entirety thusfar).

    * Personally, I'm surprised the moderation staff here hasn't just "blocked out" his network range yet honestly!

    (They know it's NOT the same as my own as well, especially after THIS post of mine, which they CAN see the IP range I am coming out of to compare with the ac spamming troll doing the above...).

    APK

    P.S.=> Again/Stressing it: NO guys - it is NOT me doing it, as I wouldn't waste that much time on such trivial b.s. like a kid might...

    Plus, I only post where hosts file usage is on topic or appropriate for a solution & certainly NOT IN EVERY POST ON SLASHDOT (like the nutcase trying to "impersonate me" is doing for nearly all of March/April now, & 230++ times that I know of @ least)... apk

    P.S.=> here is CORRECT host file information just to piss off the insane lunatic troll:

    --

    21++ ADVANTAGES OF CUSTOM HOSTS FILES (how/what/when/where/why):

    Over AdBlock & DNS Servers ALONE 4 Security, Speed, Reliability, & Anonymity (to an extent vs. DNSBL's + DNS request logs).

    1.) HOSTS files are useable for all these purposes because they are present on all Operating Systems that have a BSD based IP stack (even ANDROID) and do adblocking for ANY webbrowser, email program, etc. (any webbound program). A truly "multi-platform" UNIVERSAL solution for added speed, security, reliability, & even anonymity to an extent (vs. DNS request logs + DNSBL's you feel are unjust hosts get you past/around).

    2.) Adblock blocks ads? Well, not anymore & certainly not as well by default, apparently, lol - see below:

    Adblock Plus To Offer 'Acceptable Ads' Option

    http://news.slashdot.org/story/11/12/12/2213233/adblock-plus-to-offer-acceptable-ads-option )

    AND, in only browsers & their subprogram families (ala email like Thunderbird for FireFox/Mozilla products (use same gecko & xulrunner engines)), but not all, or, all independent email clients, like Outlook, Outlook Express, OR Window "LIVE" mail (for example(s)) - there's many more like EUDORA & others I've used over time that AdBlock just DOES NOT COVER... period.

    Disclaimer: Opera now also has an AdBlock addon (now that Opera has addons above widgets), but I am not certain the same people make it as they do for FF or Chrome etc..

    3.) Adblock doesn't protect email programs external to FF (non-mozilla/gecko engine based) family based wares, So AdBlock doesn't protect email programs like Outlook, Outlook Express, Windows "LIVE" mail & others like them (EUDORA etc./et al), Hosts files do. THIS IS GOOD VS. SPAM M

    I'm sure i'll get hatred for saying this but...who cares? you just KNOW what this will be ended up used for, if we ever see it at all, and that will be to make "iSliver" phones so God damned thin that a fart can blow the damn thing across the room and of course it'll be that much easier to lose the stupid thing while not giving us one second more run time because "Thin is in daddy-o" even though everybody I know wishes they had better battery life instead of a CC thick phone.
