Although's Moore's Law continues to race along, battery tech hasn't nearly kept up pace -- so we're excited by developments like the one just announced by Argonne National Labs, which has managed to increase Li-on capacity by 30 percent while making the batteries safer and longer-lasting. The secret ingredients in Argonne's new juice box are a new composite battery material that's partially electrically inactive and manganese oxide-based electrodes in place of the traditional cobalt oxide. Argonne says it's already licensed the tech to Japanese manufacturer Toda Kogyo, which has the capability to produce 30 million laptop batteries a year, but the lab is still working on improving charging rates -- while it's adequate for laptops and cellphones, the battery will need to discharge at least three times faster to work in a car. No word on when we might see these start shipping, but you can bet "manganese battery" is being added to our dream machine spec list right... now.

Back before we got this cushy blogger gig, we were looking into a rewarding career as lion bait. Good thing we didn't go ahead with that, since we hear the mortality rate isn't exactly top-rate, and now it looks like we'd be having our jobs replaced by a few infernal robots anyways. Some students over at Strathclyde University in the UK have developed an RC "LionDrover" vehicle that can hit speeds up to 30 MPH and is designed to give bored, captive lions the thrill of the chase. To heighten the realism -- last time we checked, most lions don't chase small 4-wheeled vehicles with hunks of meat tied on top in the wild -- the little vehicle sports some sweet zebra stripes. The LionDrover is a successor to the Lionrover, which has been around for a couple of years, and apparently a new version is in the works, too. Currently the bot is being tested out at Blair Drummond Safari Park, and should be joined soon by six similarly-fated companions once the funding is procured. There will also be versions for wolves and African wild dogs -- sounds like these are glorious days indeed to be a captive carnivore.

If you're trying to get away from that gas guzzling wheelchair, but feel a bit awkward rolling in the less-than-glamorous solar-powered edition, Suzuki Motors has got your back. Taking a leap forward from its previous lead-acid battery-powered electric wheelchair, the MIO is a motor-driven cart that gets its juice from an ultra-green fuel cell. The cell works in conjunction with a "large capacity Li-ion secondary battery," and while we aren't certain of how quickly this bad boy can streak down the quarter mile, it can supposedly cruise for 25 miles on a single fill up (four liters) of methanol solution. Aside from the power source, the MIO sports armrests that serve double duty as safety barriers, ergonomic handlebars, a comfortable mesh seating surface, and even an LCD panel that shows such useful data as fuel level and power status. While Suzuki insists the unit is simply a prototype, and refuses to hand out pricing details while it "judges consumer interest," the MIO should still be a bit easier to acquire than the sold out Tesla should it ever hit stores.

Yeah, we're trying to hold back the snickering too. It seems the IEEE has chosen now as the time to start looking over those (previously innocent) battery protocols, and the timing couldn't be any more convenient. Rather than buckling down and getting a finalized 802.11n standard out the door, the task force is being silently forced to take a good, hard look at battery criteria. Currently focused on IEEE P1825 -- the designation for lithium-ion and lithium-ion polymer batteries used in digital cameras and camcorders -- the crew is hoping to set more uniform regulations for the "design, production, and evaluation" of said cells. The update is supposedly aimed at revising "design analysis, testing and qualification checks" to ensure those QA reports filter out any, um, potentially explosive misfits, and while the project is scheduled to be completed "within 18 months," we know how quickly these folks let their deadlines slip. But the force isn't letting those increasingly-concerned computer manufactures get too much of a head start, as the IEEE 1625 is also slated for a (very necessary) revamp -- which makes perfect sense considering its label: "laptop battery standard."
