Battery of the future
First of all, no, I’m not ashamed that I’m enough of a geek to actually get excited about this. But hey, I’m an electrical engineer, and a sucker for technology. Second, no, I don’t work for Toshiba. I just heard this on the radio today and was highly interested. The application, even in my own field of embedded computing, could be utilized on some really cool applications.
Toshiba announces new breakthrough in battery technology:
Toshiba Corporation today announced a breakthrough in lithium-ion batteries that makes long recharge times a thing of the past. The company’s new battery can recharge 80% of a battery’s energy capacity in only one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today, and combines this fast recharge time with performance-boosting improvements in energy density.
The new battery fuses Toshiba’s latest advances in nano-material technology for the electric devices sector with cumulative know-how in manufacturing lithium-ion battery cells. A breakthrough technology applied to the negative electrode uses new nano-particles to prevent organic liquid electrolytes from reducing during battery recharging. The nano-particles quickly absorb and store vast amount of lithium ions, without causing any deterioration in the electrode.
The excellent recharging characteristics of new battery are not its only performance advantages. The battery has a long life cycle, losing only 1% of capacity after 1,000 cycles of discharging and recharging, and can operate at very low temperatures. At minus 40 degrees centigrade, the battery can discharge 80% of its capacity, against 100% in an ambient temperature of 25 degree centigrade).
Toshiba will bring the new rechargeable battery to commercial products in 2006. Initial applications will be in the automotive and industrial sectors, where the slim, small-sized battery will deliver large amounts of energy while requiring only a minute to recharge. For example, the battery’s advantages in size, weight and safety highly suit it for a role as an alternative power source for hybrid electric vehicles.
Of course, I don’t like the idea that it won’t be released for two more years, nor than it will find initial applications in things other than cell phones, portable electronics, etc. But when I think about what this will mean for portable electronics in the next few years, I feel the warm, fuzzy, engineer’s appreciation of technological advance.

Battery of the Future
The lithium ion battery Toshiba announced recently is great … charges up to 80% of capacity in one minute!…
