90 Percent Charge in 10 minutes

That’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

Sharp, 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
