Submission + - Battery Material Could Lead to Rapid Recharging (mit.edu)

imamac writes:

MIT engineers have created a kind of beltway that allows for the rapid transit of electrical energy through a well-known battery material, an advance that could usher in smaller, lighter batteries — for cell phones and other devices — that could recharge in seconds rather than hours.

Engineers simply coat existing battery designs with lithium phostphate, which helps the ions move more quickly into the "tunnels" of the power cell.

Submission + - Improved Lithium-Ion Battery Charges in Seconds 2

Hugh Pickens writes: "Because of the electronic punch that they pack, gram for gram, lithium-ion batteries are the most common rechargeable batteries found in consumer electronics, such as laptops. However, they take a long time to charge and researchers have assumed until now that there was a speed limit on the lithium ions and electrons that pass through the batteries to form an electrochemical circuit. The problem with existing lithium-ion batteries is the way ions passed through minuscule tunnels, whose entrances are present at the surface of the material. The team discovered that to get into these channels, the ions had to be positioned directly in front of the tunnel entrances — if they were not, they could not get through. The solution found by Gerbrand Ceder at the Massachusetts Institute of Technology was to engineer the material such that it has a so-called "beltway" that guides the ions towards the tunnel entrances. A small cellphone battery can be recharged in just 10 seconds thanks to the improved ion flow and a large battery that would be used to power a plug-in hybrid electric car could be recharged in just five minutes, compared to up to six or eight hours at present. Because there are relatively few changes to the standard manufacturing process, Ceder believes the new battery material could make it to market within two to three years."

Submission + - UK Tory Party Plans Open Source and Standards (bbc.co.uk)

Amtiskaw writes: The BBC reports that the Conservative party in the UK is planning a major overhaul of government IT projects, with an emphasis on using open source and open standards. It claims the incumbent Labour government has wasted billions on monolithic failed IT projects, delivered by a small pool of favoured large contractors, and plans a radically different approach should it gain power in the next election. IT procurement will be opened up to far wider range of suppliers, including start-ups, with open source and open standards used to ensure interoperability between different projects and departments. It claims the plans will save hundreds of millions of pounds per year, and help modernise the delivery of public services.
