Making Safer Lithium-Ion Batteries 77

itwbennett writes "Exploding iPhones may be a thing of the past. Researchers at Taiwan's Industrial Technology Research Institute have developed a new polymer, STOBA (that's self-terminated oligomers with hyper-branched architecture to you and me), that is added to the cathode material inside a lithium-ion battery to keep them from overheating. 'Fires or explosions in these batteries are caused by short circuits,' said Wu Hung-chun, a researcher at ITRI, explaining that even minor mishandling such as dropping the handset could result in damage causing a short circuit. 'The technology is ready for lithium-ion batteries used in electronic devices, mobile phones, laptops,' said Wu. And ITRI has started testing STOBA on electric car batteries."

    Now, here's a clever tactic -- spam your epic misunderstandings into every vaguely science-related thread, but do it as AC, but sign your name to each one. That way, you get all the attention you crave, you don't take a hit to your karma when you get modded down to your natural state, and, hey, if you somehow get some mod points, you can mod yourself up. Brilliant, I tell you!

    But when you have shitty charging circuitry, shitty components measuring and regulating the current and voltage, and shitty material (like fucking paper) inside the thing, yeah, shit's gonna go up in flames.

    Go talk to any real life RC community or online forum and you'll hear stories of li-ion and lipo failures from people who use quality chargers and cells. I know more than a few guys who store/charge/transport their lithium batteries in a box full of sand, just in case.

    You have confused Ni-MH and Ni-Cad.
