scib 150x150 90 Percent Charge in 10 minutesThat’s what Toshiba reckons its latest Super Charge Ion Battery (SCIB) is capable of, and the icing on the cake is that it should be able to withstand between 5000 and 6000 charge/discharge cycles, or up to ten times the number of charge cycles for a standard Lithium Ion battery pack. There’s even more good news, they won’t explode when crushed, which is probably not something most people need to worry about, but it could happen. However, there’s no word on what SCIB’s do when they are short-circuited, which is one of the possible reasons for the recent spate of well-publicised laptop battery fires. So what’s the catch? Well, Toshiba hasn’t announced a launch date yet, which usually means there are some manufacturing or cost difficulties, or both, still to be ironed out, but the idea of being able to get a dead laptop battery up and running in just a few minutes is going to appeal to a lot of power-users, so we probably won’t have to wait too long for it.

Sharper Fuel Cells

fuelcell 150x150 Sharper Fuel CellsSharp, in collaboration with MIT have announced an improved fuel cell technology that’s claimed to have the highest power density to date. Fuel cells have been around for yonks and basically convert chemical energy into electrical energy. It’s a sort of reverse electrolysis process (where water can be turned into hydrogen and oxygen by passing a current through it), using exotic materials that act as catalysts. In this case methanol is the fuel source. It’s a lot safer, cheaper and easier to transport than Hydrogen, which has been a popular choice with fuel cell developers in the past.

Sharp’s Direct to Methanol Fuel Cell (DMFC) prototypes are small enough to be used inside most gadgets, from mobile phones and GPS receivers to personal stereos and cameras and they say they’ll last around as long as lithium ion rechargeable batteries (3 – 5 years). Read more

Assault on Batteries

batteries.thumbnail Assault on BatteriesThis kindly looking old gentleman could be your next best friend, if you are thinking about buying an electric car, laptop, or indeed anything powered by lithium ion batteries. His name is Peter Roth and he’s the lead researcher at Sandia National Laboratories in Albuquerque. His team is part of a government funded research project called FreedomCAR and it is focusing on Lithium Ion batteries, which have a bit of a reputation for popping and bursting into flames. So far it’s only been a bit of a nuisance for laptop owners, with a handful of fried machines and no serious injuries or damage, but imagine what could happen when you get hundreds of them packed tightly together in an electric car.
